3/16 – Rob’s St. Patrick’s Day Weekend Forecast
Rainfall has been moving across the area since sunrise and poised to continue…
A cold front along the lower Tennessee valley will begin affecting the area with showers this morning along with isolated t-storms later morning through this afternoon. Elevated rain chances will continue into Saturday due to the previous frontal boundary stalling across the area and moisture still being in place. Thunderstorm coverage will increase again on Sunday, but more so from the next approaching system. Models show close low racing across the southern portion of the Central Plains Sunday into Sunday night. Local showers and thunderstorm development will be enhanced by lowering surface pressures and lift along a pre-frontal trough swinging through. Another chance for low end severe storms will be possible. This round there will be more shear to support severe storms due to the low being 7291890 closer to the area.
The actual cold front will not get here until Tuesday morning when another trough digs south across the lower Mississippi Valley. Broad toughing will then persist across the area through much of the rest of next week. This will keep temps at to below normal during that time frame and a dry forecast with no rain till possibly the following weekend.
