High temperatures should be warmer than average once again in the lower to mid 80s.
A low pressure system in the southern Plains will push eastward across the Lower Mississippi Valley tomorrow night and then move into the Carolinas by Tuesday afternoon. We could see the development of showers over the northwest and northern portions of the forecast area this evening and overnight, but the threat of thunderstorms through the evening hours will be close to zero.
Showers and a few thunderstorms will be rolling through the area beginning early Tuesday morning and continuing on and off through Tuesday afternoon. Rainfall totals will be low, only at around a quarter of an inch on average.
Tuesday afternoon will see rapidly improving conditions as the front races to the east. The front should be clear of the area by mid-day, and clearing skies and lower humidity values are anticipated by Tuesday afternoon.
Cold air on the back side of the front will be delayed, and a westerly winds will support another warm day with highs climbing into the lower to middle 80s. The cold air will finally push into the area by Tuesday night.
Temperatures should cool into the upper 40s and lower 50s which is actually closer to seasonal norms for this time of year.
