12/14 – Rob Knight’s “Final Week Of Autumn” Afternoon Forecast
The next potent disturbance will move across the lower Mississippi Valley/central Gulf coast region late Tuesday night into Wednesday morning. Rain and showers will be likely with this system Tuesday night, however most areas should again see rainfall amounts mostly under one-quarter inch. The rain chances will be ending rather quickly into Wednesday morning leading to what should be at least a partly sunny and dry afternoon Wednesday with cool highs in the mid-50s to near 60.
A cold area of surface high pressure will settle over the central Gulf coast region Thursday into early Friday. Thursday morning low temperatures will likely be near a light freeze in southwest Mississippi with mid-30s and frost down to the I-10 corridor: coastal Mississippi should be in the upper 30s to lower 40s.
The surface high will shift east of the area Friday and Saturday, and the next disturbance and cold front will move across the area Saturday and Saturday night with a decent chance of showers and possibly a few thunderstorms. Temperatures should trend closer to normal through the weekend.
