Seriously, where is fall?? And a final note from intern Jennifer...


At this point in September I'm feeling a little relatable to Veruca Salt - I want fall and I want it now. I know we're all wishing for some cooler weather, but not seeing much relief in sight for the foreseeable future. For the past week our highs have been about 10° above average for this time of year. In addition to this heat, we are also getting dry. We're halfway through September and have had 0.00" of measurable rainfall. Wow! Let's go ahead and dive in to what we can expect for this next week, and look at some long term models to see what they're thinking.

This map shows the precipitation totals for the mid-south for the past 30 days. As you can see, most of the Memphis metro has not received even an inch of rain in the past month.  


Monday and Tuesday

Ah, I went ahead and clumped these two days together because they have the exact same forecast. At this point I think you can assume what it is (hint it's been the same weather for the past several days). Highs in the mid-to-maybe-upper 90's with heat indices maxing out around 102°. Mostly sunny skies with a 0% chance of precipitation. Those open skies make way for some cooling overnight with lows in the mid-70's. It's a scorcher, so be sure to continue practicing those precautions for hot days.

Wednesday and Thursday

Is this Memphis? Feels like it. 

Mostly sunny and hot conditions will persist as that upper ridge of high pressure above us sticks around and strengthens in fact. Highs for both days are in the mid-90's and lows in the mid-70's. However, as clouds begin to pick up on Thursday, we do have a slight change in the forecast beginning Friday. 


The Weekend

Friday we start to see a slight chance for some thunderstorms developing, but only bringing that up to a 20% chance for now. In other words, don't get your hopes up! Drought tends to beget drought. Not a huge cool down expected with this however, with highs still in the lower-90's.  Lows in the mid-70's for Friday night. Partly cloudy skies will linger into Saturday and Sunday, cooling it down just a tad with highs near 90. By the end of the weekend and into next week high pressure may once again take over, but it appears that this week may be the end of the extremely hot conditions. Let's hope for some 80s! 


Long term

Pumpkin Spice products may be filling the shelves, but with these 8-14 day outlooks, it seems by the end of September fall-like weather still won't be here. Precipitation for the mid-south is "near average" (which might actually mean some rain will fall!),but to our north in the Plains it is looking to be even drier. The temperature map is showing about a 50-60% probability that our temps will be above average. Don't unpack those sweaters quite yet, but rather appreciate the last couple of pool days we can squeeze out of this season!

A final note...

This was a bittersweet blog post, because it is my last one with MWN. I am very happy to announce that I have accepted my first on-air position as a meteorologist down on the Gulf Coast in Mobile, AL at the WALA FOX10 station. I will be working in the evenings alongside the Chief Meteorologist. I have had a wonderful time living in Memphis and interning for MWN. I appreciate all of our loyal followers who interacted with me through the social media platforms. Also a huge thank you to Erik, who helped me develop as a meteorologist and also assisted in my social media presence growing. I enjoyed my time in the mid-south, and I will come back to visit plenty. Thank you to everyone!

Summer 2019 just won't give up

A few weeks ago, it looked like we might be starting to see a reprieve from summer conditions as we headed into September. It seemed like a good forecast at the time! Meanwhile, here we are in the second week of September dealing with another string of mid 90s temperatures. In fact, Monday's high temperature of 98 degrees was the warmest of the summer - or last summer for that matter! What can we expect in the week or so to come? Glad you asked...

Mid-week

We might end up with a bit of an unexpected reprieve today - thanks to a persistent mid-level cloud deck - as temperatures sit in the mid 80s just after the lunch hour. The clouds are slowly lifting to the north and we should end up with some afternoon sunshine that will warm things up pretty quickly. But there might not be enough daylight at that point to make it much over 90. We'll take it!


The sun returns Wednesday and Thursday with mid-summer-like high pressure building at the upper levels. That will warm the low levels back up to the mid 90s for mid-week with almost no rain chance. It's been a long time since we've had meaningful rainfall and that dry ground is contributing to warmer temperatures! Dewpoints will run near 70 degrees, which is humid, but not intolerable. That will mean heat indices likely peak in the 100-105 degree range. Keep that in mind for any outdoor activities!


This weekend

By this weekend, the upper level ridge of high pressure starts to break down a bit, but hot weather continues, abating just a bit as we get towards the end of the weekend. It still looks mainly dry, though a stray shower can't be ruled out as the high weakens a touch.  Look for highs in the mid 90s through Saturday then a bit cooler Sunday.



Early next week

Unfortunately, there are no big cold fronts sitting on our front door waiting to push through, but with high pressure loosening its grip just a bit, a front will likely stall out near our area. There also could be a subtropical or tropical wave near the Gulf coast early next week that could have an influence on our weather pattern early next week. We'll look for highs near 90 degrees with a measure of humidity and mainly afternoon rain chances. Speaking of rain, it's certainly gotten dry the past couple weeks after an overall wet summer hasn't it??

Unfortunately, even the longer-range outlooks still paint our area with a strong chance of above normal temperatures. The only good news is that those "average temperatures" cool a fair amount during September, so mid to upper 80s could be above normal within a week or so. Hang on folks! Fall will be here soon!

The Climate Prediction Center forecasts a high likelihood (60%+) of above normal temperatures across the Mid-South for the period September 17-23.
