Rain returns Thursday, then more sun and pleasant temps this weekend

After a somewhat chilly end to last week and near-average weekend, temps have rebounded to above average and will stay there through tomorrow. As another round of showers and some thunderstorms knocks on our doorstep for Thursday, temps will fall back to just below average. Luckily, following these showers, sunny skies and near-average temperatures will make their return for the weekend. Overall, after Thursday's rain, we look to stay mainly dry for the foreseeable future.

Rest of today

Pleasant conditions are expected to hang around for the remainder of the day. Satellite imagery from this afternoon shows a few more clouds beginning to move into the area. Expect for this trend to continue as we move into the evening hours.

Tonight, expect for skies to remain mostly cloudy as overnight lows fall to near 62.


Tomorrow appears to be one of those it may rain/it may not type of days. What do we mean by this? Well for the first half of the day through the early afternoon hours, we should stay dry for the most part with mostly cloudy conditions overhead and highs nearing 79. However, by mid-afternoon to evening hours we will become fair game for some scattered shower activity. Most computer models want to keep scattered showers primary to our north, but it will be pretty close. A stray shower cannot be completely ruled out.

Widespread showers are not expected to arrive until early Thursday morning. 


We've got some bad news for you Miss Rhode Island, Thursday does not appear to be that great of a day weather-wise. Highs will reach near 72 by the afternoon, so a light jacket probably won't be needed. However, you will want a rain jacket and/or umbrella. Showers are expected throughout the day with a few thunderstorms possible.

Now you may be thinking, are we expecting yet another round of severe weather? Luckily, no severe weather is expected with any thunderstorms that may develop, just heavy rain and lightning at times is possible. Why, you may ask? Well, it all has to do with the low pressure system driving the cold front helping to bring the precipitation. The low pressure system (you may have noticed this on the precipitation loop above) tracks through Arkansas and into Mississippi without going to our north. For us, this a good thing because it keeps some of the severe weather ingredients needed away from our area and to the south, leaving us with just some general thunderstorms. 

If you want another nerdy explanation/visualization, look no further. The graphic below represents 300mb (jetstream level) pressure and wind, which is just a big fancy way for meteorologists to get an idea of the overall flow pattern in the atmosphere (i.e. where the trough/ridges are). At the beginning of the graphic, we can see faster winds over the western U.S, forming a ridge-like pattern. By the middle of the sequence, you can see some of these upper-level winds beginning to create a trough-like feature over the eastern half of the U.S. You may notice the bottom of this trough (the U type appearance) moves through areas primarily south of the Memphis area. This just goes to show that what is occurring high in the atmosphere is driving what is occurring at the surface (i.e. where the bottom of the trough is located is closely located to where the "L" appears on the graphic early).

The map above represents 300mb height and winds from Wednesday evening through Friday afternoon. Areas in color represent faster wind speeds, where areas that appear white mean generally slower wind speeds. (Pivotal Weather)

Going back to what we can expect on Thursday, heavy rainfall will be possible at times and could lead to some ponding in low-lying areas. Although, widespread flooding is not expected. When all is said and done, most of the Mid-South is expected to receive around an inch in rainfall, more or less. 

The Weather Prediction Center's precipitation forecast shows around an inch of rain falling across much of the Mid-South between Wednesday's slight chance and Thursday's widespread chance of rain. (Pivotal Weather)


Wave goodbye to the gloomy weather and rain because beginning on Friday we are expecting lots of sunshine in our forecast. Mostly sunny conditions are expected throughout the day with highs reaching near the mid 70s. Keep those sunglasses handy folks!

This Weekend and Next Week

Sunshine for all! Besides some mainly high clouds and a very small chance of a shower, this weekend looks pretty fantastic if you ask me. Temps will remain near average in the mid 70s with overnight lows in the 50s. Saturday and Sunday look to be a good combination of warmer temperatures, but not too warm that they are unbearable. If you have outdoor plans this weekend, enjoy them!

Into early next week, rain chances should remain minimal to non-existent as much of our area remains under the influence of a high pressure system. Additionally, temps could get pretty toasty next week, with highs expected to rise into the 80s.
