Today was another summer day! Highs reached 84-89. Highs tomorrow will reach 85-90, as they will Sunday. Enjoy summer in mid-September this weekend with mostly sunny skies Saturday & skies becoming partly cloudy Sunday.
Heat indices will peak at 88-94 with east to east-northeast winds at 8-16 mph. Lows will drop into the 60s at night.
It still appears Florence will dump heavy rainfall, leading to massive flooding in the Coastal & Piedmont Carolinas, right into the Appalachians.
As for us, a very weak cold front Monday-Tuesday may bubble up a few isolated showers/t'showers here with humid 80s.
Wednesday looks dry with 80s.
However, as strong cold front approaches Thursday, the old circulation from Texas tropical disturbance will ride up into our area. As it combines with a disturbance/low pressure out of Colorado to Kansas, lots of showers/storms will blow up.
After a windy, very warm to hot, humid Thursday front/storm system should blow up severe weather to our west & northwest Thursday. Severe weather is possible Thursday to Thursday night northern Missouri to southern Wisconsin, Illinois & even far northwest Indiana.
As for us, we may see some severe risk Friday with rain/storms moving in with windy conditions. Also, widespread 1-3" rainfall event is possible.
Supercell Composite Index for Thursday PM:
At this point, it appears that some isolated severe risk may occur Friday.
Note the high Precipitable Water values pulling northeastward into our area from Texas, which will enhance the rainfall.
Much cooler, windy weather will rush in next weekend with highs only in the 60s to around 70 & lows in the 40s.
The remnants of a Pacific tropical system with another strong cold front will bring widespread rainfall after that. Another brief warm-up with gusty winds will precede it.
After that, an even colder shot of air will plunge in. Overnight lows in the 30s to 40s are likely with highs only in the 50s to 60s.
