Rainfall over the past 24 hours has been very spotty in nature and that trend continues. The few storms that are developing are slow movers and they are producing tremendous amounts of rainfall. Marion County has been a hot spot lately, with rain totals topping five inches. Earlier today a flash flood warning was issued for Lamar County.
The chance for a passing storm or shower will continue through the evening hours tonight. A boundary has stalled over the area and this could serve as a focal point for some lingering rainfall activity. The boundary will continue to weaken with the storm threat shifting a bit eastward tomorrow. It looks like rain will become more isolated tomorrow and on Wednesday due to very weak forcing. Each day we will have heat index values nearing 100, with partly to mostly sunny weather. The storms should primarily be limited to the mid to late afternoon hours and triggered by the peak heating of the day.
A strong upper level storm is expected to move across the Great Lakes region and carve a broad trough out over the eastern United States. This should enhance our coverage of afternoon storms and showers for Thursday and Friday as another front marches southward. Models suggest this front could make a strong push through our area over the weekend. This scenario could certainly bring some heat relief over the weekend, especially over the Tennessee Valley. Right now we’re forecasting highs in the upper 80s for Saturday, with lows in the 60s. By the way, Tropical Storm Ernesto remains on a westerly course and this system is not expected to impact the Alabama Gulf coast this week.
