8/27 – Rob’s Monday/Workweek “Wet” Forecast
High-pressure is now centered over the Appalachian Mountains. This has opened the area/region up to deeper Gulf/Caribbean moisture and minimal subsidence to inhibit convective development. The combination of minimal subsidence and ample moisture throughout the atmosphere will create an environment conducive for scattered to numerous showers and thunderstorms today. Expect lower precip chances in areas east of I-55 and higher west of there. This range however is only from 50 to 70 percent. T-storms will fade in the late afternoon and early evening as the sun sets.
The pattern will will gradually shift east into the western Atlantic Ocean and become anchored there through at least the rest of this week. This will result in a relatively stagnant forecast with 40-70% coverage each day. In terms of temperatures, outside of storm influences, highs should be near climatology each day. We will have to monitor heat indices for areas south of the interstate. Biloxi touched 104 yesterday and will likely be close to that each day as dewpoints hover near 80 while temps quickly rise.
