It's already a mild start to the day as temperatures only dropped to 70 last night. A surface high over the Ohio Valley and a surface low pressure over the Plains will continue to provide southerly winds throughout the day, which should allow us to be rather warm again. Aloft, a rather unimpressive ridge covers the Deep South but this will also continue to support warm temperatures. The main impediment for really warm temperatures today is again the presence of cloud cover. Skies will range from partly cloudy to mostly cloudy at times today, but highs this afternoon should be able to top out near 85. With the soupy air mass in place and slightly cooler temperatures at 700 mb, there will likely be a few scattered afternoon storms. By this evening, cloud cover looks to increase once again and there will be a very small chance for an overnight shower or thunderstorm but most areas should remain dry though. Look for the low to be a muggy 68.
The weekend could be wet at times, especially Saturday afternoon through early Sunday morning as a cold front approaches. This front will pass through on Sunday and will usher in a cooler and drier air mass for early next week. I'm not ready to bite off on the GFS' forecast of upper 40s on Monday morning, but we should be well below normal in the temperature category for a couple of days next week.
