The heat will continue to build for at least another day or two before some relief arrives late Sunday or Sunday night. That is when a cool front will arrive which will at least knock temperatures back to near normal after enduring several days of much above normal temperatures. In fact, triple digits are expected for this afternoon and again Saturday afternoon from along and west of Hwy 75. The more eastern counties should be spared the triple digit heat, but it will be close.
Quite frankly I had thought the cool, wet spell we enjoyed in the middle of August would prevent any triple digits to end the month; but this late summer heat wave looks like it will be strong enough to make it happen anyway. We expect to be right at 100 this afternoon and Saturday afternoon will likely be the hottest of this cycle with some lower 100s a good bet. Sunday will also be hot, but more cloud cover is expected in advance of an approaching cool front and that should keep temperatures in the mid-upper 90s, so it will be close again on Sunday.
After that, we get some relief as the cool front pushes through the state Sunday night followed by a brisk NE wind for Monday. Upper 80s to lower 90s are then expected through the middle of the week which is at least closer to normal for this time of year.
Wish I could say we will also get a good soaking when that front moves through, but right now it looks like only some scattered showers/storms can be expected during the day Sunday and through the overnight hours, ending Monday morning. At least that suggests Labor Day itself should be relatively pleasant with a brisk NE wind, lots of sunshine, and daytime temperatures near 90.
After that, a stronger cool front with the potential for better chances of showers/storms should be coming our way along about that following weekend. Too early to get too excited about those prospects, but that looks to be our next best chances for widespread showers/storms.
In the meantime, stay tuned and check back for updates.
