More warmth this afternoon combined with a disturbance in the upper levels of the atmosphere will set the stage for at least a few showers and thunderstorms. The timing and placement of these storms is up in the air as models do not have a good handle on the current situation, but it appears as if mid-afternoon to mid-evening is our best chance for scattered thunderstorms.
Come Wednesday, a surge of cooler and less humid air will be approaching the region from the Great Lakes. The leading edge of this cooler air is a cold front and ahead of this cold front winds will increase from the west and southwest, however, behind the front winds will be coming from the northwest. The upshot of it all means that we could warm to near 90 Wednesday, ahead of the cold front, with numerous showers and thunderstorms likely as the front passes through the region later in the day. Unlike the past couple of days, heavy rain won’t be the only threat from Wednesday’s storms. The winds aloft will finally strengthen a bit so some of the storms will have gusty winds.
It still looks like a break in the heat and humidity behind the cold front. While there may be a shower or thunderstorm Thursday, the humidity should be on the decline throughout the day. This will set us up for a gorgeous day on Friday with seasonable temperatures and low humidity.
While it looks like it will warm up again next weekend, how the rest of our weather unfolds is a bit up in the air. There are some signs that the return of humid weather will be delayed and if that is the case the weekend could end up dry. We are not totally confident of this happening just yet and that is why we are keeping at least a low chance for a scattered shower or thunderstorm Saturday and Sunday. Stay tuned.
