Good morning! Patchy fog can be seen across East Tennessee this morning, so use caution as you head out. Through today, we will see a mix of cloud cover, sunshine, and isolated showers. The bulk of this will begin to edge in tonight, as a warm front builds north across the area. A few rumbles of thunder also can't be ruled out. Highs today will top out in the upper 70s to low 80s.
With showers working in this evening and overnight, they will dissipate out toward the early morning and through the early afternoon Wednesday. This will give way to some sunshine as temperatures warm into the mid 80s. Following, a low pressure system (currently in the Southern Plains) will swing through. This will bring widespread showers & thunderstorms Wednesday night and throughout Thursday. The severe threat is low, but not zero. As such, a marginal risk (1/5) is in place and we'll keep an eye on how this whole system evolves.
With rounds of showers & storms expected, some of which could be strong at times, a risk for flash flooding will present itself. This coming from the WPC where a marginal to slight risk for flash flooding is in place Thursday. Rainfall totals will likely topple 1 inch Wednesday night and through Thursday, so know what to do if you live in flood prone areas and low lying locations.
Drier conditions will then prevail through Friday, with a very pleasant and warm holiday weekend on tap. This will continue into Memorial Day as well, with highs Saturday through Monday ranging from the upper 70s and warming towards 90 degrees.
