Cooler temps for all, rain chances today and to end the week

Oh fall, you have been so good to us this week. I don't know about you, but I have certainly enjoyed the cooler weather we have had over the last few days. Thankfully, this cooler weather looks to stay for a while as we head into the second half of October. Today will continue to be a bit soggy, but we do have a break from the rain chances coming.


While we've stayed relatively dry so far, expect for that to change as we push through the day. Light showers continue to drift towards our area as we speak and will reach us by this afternoon.

While showers should remain light, they will stick around long enough that you will likely want to keep your umbrella handy for the rest of the day. This will be a chilly rain folks. 

Additionally, temps will not warm up that much today. Temps currently sit in the mid 40s and will only rise into the mid 50s by the end of the day. This will leave our highs nearly 20 degrees below normal ("normal" is around 74). Luckily temps won't fall too much overnight, leaving lows around 46 under a mostly cloudy sky.

Tomorrow & Thursday 

After our wet day today we will see a brief, couple day break from all of the soggy rain. Tomorrow and Wednesday look like pretty nice days to embrace the fall weather. While some clouds will be present each day, enough sunshine will be around to help highs warm into the low to mid 60s (which is still a few degrees below average). Overnight temps will cool off into the mid 40s. 

Friday & Saturday

Our period of dryness could only last so long as rain chances return to end the work week and begin the weekend. The main time frame we are looking at showers is anytime from Friday afternoon until Saturday morning. Friday morning and Saturday afternoon/evening look to remain dry at this point. Highs will remain in the low to mid 60s both days with overnight lows falling into the low 50s to near 50.

Next Week

After Friday and Saturday morning's showers, we will begin to transition into a pretty dry period. Most models and outlooks for next week show minimal rain chances through the majority of next week. For those who have wanted a break from the soggy weather, it's coming.

The good news along with this period of dryness is that temps will remain cooler. Even though high pressure looks to build in for much of next week, temps look to remain below average.

Fall Is Here, Sergio brings Sunday rain, then Cold Blast #2

It is no argument that Fall has finally arrived with the surge of cooler air. All of that is thanks to Wednesday's cold front that came through. We do have some changes coming in the forecast over the next seven days; however, no worries! Our cooler weather is here to remain. Instead, we do have a decent amount of rain on the way, thanks partially to Sergio.


A weak boundary moving through this afternoon and into tonight is bringing a short lived chance at some stray rain this evening and into tonight. As mentioned, rain will be light. Likewise, the wave will be weakening as it moves through so not everyone will see rain.

Clouds that arrive with this rain will be sticking around overnight and into tomorrow. These clouds will hold in some heat tonight, preventing us from dipping into the 40s. Instead, we will see lows in the lower 50s. Rain chances drop off tonight and we remain dry until at least mid-day Saturday.

Tomorrow (Saturday)

We start the weekend dry Saturday, but Sergio, formerly a major hurricane in the eastern Pacific that made landfall in Baja California early this morning, plans to change that, along with the help of a new low pressure system. That new developing low is what picks up Sergio and brings it over to the Mid-South. The moisture from this tropical remnant will start to bring light, scattered rain as early as late Saturday afternoon. As we move into the night, rain chances quickly ramp up. Thanks to the clouds Saturday afternoon, high temps remain in the upper 60s. As it stands now, most of the University of Memphis football game vs. Central Florida should remain dry, though if rain does arrive during the contest, it will be light.

3km NAM brings 1-1.5 inches of rain for the Memphis area by Sunday afternoon thanks to Sergio's remnants. (WeatherBell)

Saturday night, rain chances ramp up as steady rain moves in thanks to Sergio's remnants and a northward bound warm front from the parent frontal system that will be steering Sergio. That lifting warm front will bring in some warmer air, so Saturday night we only drop into the upper 50s to right at the 60 degree mark.

Sunday and Monday

If you thought that rain was going anywhere any time fast, you were wrong. The front takes its sweet time getting out of the Mid-South. That said, look for showers through the day Sunday, Sunday night, and into the earlier half of Monday as well. Lighter precipitation is possible during a relative lull Sunday afternoon, but look for rain rates to pick back up Sunday night.

Rain chances remain high, seen here with simulated reflectivity from the GFS model for Sunday evening. (Tropical Tidbits)

Temps through this time will remain slightly warmer than what we've recently seen, until Monday. Sunday climbs into the lower 70s. Sunday night, as the front pushes through, temps will be dropping into the mid 50s. By Monday, the front will finally be bringing with it cooler weather, so our high around 63 will be earlier in the day.


Here comes some serious cooler weather, so prep for a true surge of Fall obsession! With the front moving through Monday, Tuesday looks to be the coolest part of our upcoming forecast. Lows Tuesday morning will be in the upper 40s as clouds linger. As we move through the day, there will remain the slight chance of a shower as the front finishes its exit. Meanwhile, cooler air keeps funneling in. By that afternoon, we will only top off in the mid 50s. Talk about Fall-feels!

Look for a new surge of cool air Monday afternoon into Tuesday with lows Tuesday AM in the upper 40s. (WeatherBell)


Wednesday starts with another chilly morning in the upper 40s for lows. In fact, Wednesday, Thursday, and Friday mornings will see lows in the upper 40s. Highs remain pleasant not only for Wednesday, but Thursday and Friday as well where we will have highs in the mid 60s. Skies conditions will vary through this period as Wednesday will see a mix of sun and clouds. Thursday will see cloud cover increasing. By Friday, skies will be mostly cloudy as rain chances start to slightly increase with the introduction of a new system.

Above average temps are almost gone, make way for fall weather!

It's crazy to think that it is almost mid-October and yet we are still setting records. Just yesterday we tied the record for the most consecutive October days at 89+ degrees. Luckily, for those ready for #sweaterweather, fall looks to be on the horizon. A cold front will push through the area late tomorrow, ushering in much cooler temperatures. Additionally, these cooler temperatures look to be hanging around for a while, so get ready for some more fall-like weather folks.

We have had a few questions about Hurricane Michael currently in the Gulf of Mexico. While this system posses no threat to the Memphis area, this is a very powerful storm that is expected to make landfall along the Florida coastline tomorrow. If you are in the area vacationing for fall break, or have friends/family there, be sure to heed all evacuations and listen to local officials about your specific location.

For more information, visit the National Hurricane Center's website at www.nhc.noaa.gov/ 
The cold front moving through our area tomorrow will actually help to quickly steer this storm to the East and away from the U.S. 


Clouds will continue to increase this evening as our aforementioned cold front pushes this way. We could see a shower or two this evening, but the majority should hold off until early tomorrow morning into the daytime tomorrow. 

HRRR model shows a line of showers and thunderstorms slowly drifting eastward overnight and becoming more scattered tomorrow as they move across our area. (WeatherBell)

This blanket of clouds overhead tonight will help to keep temps pretty warm with lows only reaching the mid 70s. 


Our much anticipated cold front arrives tomorrow, but first we must get through one more day of highs in the 80s. 

Overall, tomorrow's cold front will be a little different than the cold fronts we usually see this time of year. We are not expecting a washout and no organized severe weather is expected. Really, many of us may be a tiny bit disappointed in the rainfall we see. Showers and an isolated thunderstorm will be possible throughout the day, but should remain fairly scattered especially into the afternoon hours.

WPC graphic shows the cold front being through our area by tomorrow evening. Rain chances will decrease as the front pushes farther eastward. (NOAA/WPC)

The majority of any scattered showers that do develop should begin to move out by tomorrow evening. Skies will gradually begin to clear tomorrow evening along with cooler temps moving into the area. Lows are expected to dip into the 50s tomorrow night.  

Thursday & Friday

Highs in the upper 60s to near 70. Lows near 50 (and maybe even in the upper 40s in some parts). Oh, and no rain chances. Any way you slice it or dice it, fall looks arrive with a bang on Thursday and stay around for a while. I know a lot of people have been waiting on it, so get your fall activities ready!

This weekend into next week

Say hello to more fall this weekend! Temps will coast in the 70s through the weekend, however, yet another cold front looks to pass through early next week, dipping our high temperatures down even further into the 60s. That's right, highs in the 60s with overnight lows maybe even dipping into the upper 40s. 

Besides some rain chances Sunday and Monday, things look to dry out behind this second cold front into next week. 

Climate Prediction Center (CPC) keeps the Mid-South temps below average through the majority of next week. (Pivotal Weather)
CPC keeps our area right along the slightly above to above average category for precipitation through next week. (Pivotal Weather)
I hope you all enjoy the cooler weather that's on the horizon; I am certainly ready for it!

Above normal temps continue, a glimmer of hope towards the middle of next week

Well, Mother Nature certainly hasn't let up on the heat this week as we have neared record temperatures a few days and even tied the record high yesterday. For the near future, things do not appear to change. Highs will remain above average and way too hot for October if you ask me. Rain chances will remain isolated at best. We do have some exciting news as we look ahead towards the middle to end of next week, so you'll just have to keep reading to find out what it is.


We've already reached the upper 80s today with no intentions of stopping there. Plenty of sunshine will help temps to continue to climb this afternoon as we near our high of 91. Why won't these summertime temperatures go away? Well, we have a high pressure currently parked over much of the southeastern U.S. and until something can push this high pressure out, our temps will remain above average unfortunately (or fortunately if you like the hot weather).

High pressure remains well in control over most of the southeastern U.S. (NOAA/WPC)

Temps will fall to 73 overnight under a clear sky.

This weekend

Busy weekend ahead here in Memphis with the Mempho Music Festival and the University of Memphis homecoming game Saturday evening. Depending how you look at things, Mother Nature has provided some good and some meh for this weekend's weather.

The good news is that rain chances will remain minimal, so most of us won't have to worry about rain chances "raining on our parade". This means that sunshine will be around through the entire weekend. The not so good news is that we won't really see any relief from the well above average temperatures we have been experiencing. Highs will tip toe to near 90 both days this weekend with heat index values reaching even higher than that. 

This may be a bit strange to stay for October, but sunscreen and plenty of water is advised for this weekend. With all of these fun, outdoor events, don't let the calendar date fool you; it'll honestly feel more like August than October this weekend. Try to stay cool folks!

A quick glance into next week

For the first half of next week, things look to remain the same. Southerly winds will continue to usher in muggier temperatures with highs in the mid to upper 80s and overnight lows in the lower 70s. Dewpoints will remain in the upper 60s, with isolated thunderstorm chances in the afternoons.

But wait, there is a glimmer of hope as we look to next week.

Medium-range models are hinting at a cold front passage towards the middle of next week, which could bring some decent showers and thunderstorms along with cooler temperatures behind it. While we can't make any promises, this front should usher in some highs in the 70s, which would be really nice to have given the above average streak of high temperatures we're currently in.

This is several days away, so timing and location of the front could still change. However, at least there is a hope that cooler temperatures are on the horizon.

Temps continue to rise; hot for the second half of the week

Just as we were beginning to enjoy the taste of fall, Mother Nature has decided to bring back a semi summer-like pattern to the Mid-South. Throughout the week, high pressure will be building in along the eastern seaboard which will keep winds out of the south. This southerly flow will usher in muggy air and allow temperatures to reach into the mid to upper 80s throughout much of the week.

Unfortunately, even as we look ahead to this weekend and early next week, models are still hinting at this above average temperature pattern. It may be October, but this first week won't quite feel like it.

Along with this high pressure system, rain chances will be spotty at best through the week. Today through mid-week we will have a slight chance of showers and thunderstorms primarily through the afternoon hours. Most of us will likely stay dry, but some of us could win the rain lottery. For the second half of the week and into the weekend, still could see an isolated shower or two, but coverage should be kept to a minimum.


Temps and dewpoints will continue their steady climb today as we welcome October with some above average temps. This increase in moisture will allow widely scattered showers and thunderstorms to potentially develop later today.

The HRRR shows scattered showers developing this afternoon with coverage decreasing after sunset. (WeatherBell)

Highs will reach 86 with overnight temps falling to near 72.  


We will begin to notice temperatures rising even more tomorrow with highs expected to near 87 degrees. Things should be somewhat similar to today with mostly cloudy skies and a chance of showers through the day. Showers and isolated thunderstorms should remain widely scattered. Overnight temps will return to a mild 73. 

Wednesday through Friday

Starting Wednesday, things will get rather toasty with highs each day reaching the upper 80s with some days attempting to near the 90 degree mark. While we may not reach 90, it will still be really hot for October and heat indices will reach the mid 90s with the dewpoints back near 70.

Looking at our overall weather pattern, a high pressure system will continue to build into the Eastern half of the U.S. through the second half of the week. This will help to keep rain chances low, but not completely zero either as a pop-up t'storm or two could develop. 

While it would appear as if a cold front is coming down towards our area, it will unfortunately never make it as the boundary will stall out well to our north. High pressure will remain in control. (NOAA/WPC)

Weekend and beginning of next week at a glance

This upcoming weekend into next week looks to be a general continuation of the second half of this week. Temps will generally stay above average with widely scattered showers and thunderstorms possible each day. 

The Climate Prediction Center (CPC) keeps temperatures well above average through the weekend and into the beginning of next week. (Pivotal Weather)

The CPC keeps the Mid-South right on the edge of slight above to above average precipitation. (Pivotal Weather)

Scattered showers for now, cooler temps & sunshine in sight

Happy Tuesday everybody! It's has been quite dreary over the past few days if you ask me, but luckily things have dried out a bit so far today (this could change later tonight though stay tuned). Right now, we are waiting on a nice cold front to pass through the area that has taken its' sweet time getting to us. This front will help to push out all of this rain and usher in more fall-like temperatures by the end of the week.

I'm certainly ready for some more fall weather. We've seen a lot of rain over the past few days and some of you may be wondering how much more we will see. Well, it depends where you are across the Mid-South region. The Memphis area is right on the bubble of getting not a whole lot to getting a pretty good bit of rain over the next week. The majority of this will fall between today, tomorrow, and then the beginning of next week. 

Weather Prediction Center's 7-Day Quantitative Precipitation Forecast shows the Mid-South receiving anywhere from a quarter of an inch up to about 2 inches over the next week. (NOAA/WPC)
There is a break from all of this rain coming folks and it will be nice when it gets here.

Today & Tomorrow

Our afternoon break from the rain is soon to be forgotten as more scattered showers and maybe even a thunderstorm or two are suppose to move through this evening into the overnight hours. I am still optimistic that the afternoon will stay relatively dry, though outdoor fields will likely still be muddy from yesterday and this morning's rain. Scattered showers should begin to arrive around to a little after dinnertime this evening. Temps will cool to near 70 overnight.

HRRR displays scattered showers and thunderstorms moving through portions of the Mid-South beginning later this evening into early tomorrow morning. (WeatherBell)
Tomorrow morning's commute may be a little soggy as scattered showers will be pushing through the area right around rush hour. We could see a few heavy downpours as these showers push through.

NAM 12km has showers arriving late tonight, sticking around through tomorrow morning, and leaving in the afternoon tomorrow. (Tropical Tidbits)
Showers and isolated thunderstorms will hang around into the early afternoon hours tomorrow. Things should clear out by the late afternoon for any sports practices, but once again fields will likely still be fairly wet from the rain earlier in the day. Clouds throughout the day along with these showers will help to keep temps in the 70s throughout the day.

You may notice that our temps will be much cooler tomorrow than today. Well, we've got some good news for you. As tomorrow's showers are moving through, so will a cold front that will bring cooler temps to the area for the remainder of the week.

WPC's front and weather type graphic highlights the change for showers tomorrow as the much-await cold front pushed through the Mid-South.
This cold front will push through entirely by Wednesday evening, so temps will get much cooler overnight with lows in the low-60s tomorrow night. While this isn't too cold, it is much cooler than we have seen in recent times, so you may need to pull out some fuzzy socks to walk around in if you are into that sort of thing.

Thursday & Friday

Hello semi fall-like weather! It will finally arrive Thursday folks.

We will have some lingering clouds on Thursday, but skies will clear out by Friday to make way for plenty of sunshine heading into the weekend. Highs will be in the mid 70s on Thursday with highs near the upper 70s on Friday. Overnight lows will be in the low to mid 60s.

This Weekend

Saturday appears to be the "better" day of the two this weekend with sunny skies and highs near 80. Northerly winds will remain which will help to keep that muggy feeling out. Unfortunately into Sunday winds will begin to shift more eastward and eventually southerly. This wind shift will allow dew point temps to begin climbing back up, bringing that somewhat sticky feeling back into the Memphis area.

GFS model dew points and surface winds shows cooler, drier dew point temperatures with our northerly winds for the first half of the weekend with warmer, more moist dew point temperatures returning by Sunday along with our southerly winds. (Pivotal Weather)
Temps will begin to warm Sunday as well with highs nearing the mid 80s under a partly sunny sky.

Next Week

Our cooler temperatures could only last so long as warmer temps in the 80s are expected to return next week. The Climate Prediction Center (CPC) has the Mid-South included in the above average temperatures category and slightly above average precipitation for next week.
