The elevated UV index and higher pollen count are just additional concerns on how a perfectly sunny day could be a problem. The Heat Advisory issued earlier this week is still in effect for today for central MS, the delta and nearly all counties along the Mississippi River. Highs are expected to climb to near 96 degrees; the heat index may hit 100 as early at 10am this morning and 'stay' there or go higher. There's a 20% chance of rain, but that's not looking like a sure bet at all, winds SE 5.
Tonight we'll have a better chance of spot showers in the forecast as the moisture in the atmosphere goes on the rise. Temps will fall back to the mid 70s, but more clouds will be in place. Thus, the increased moisture may give us more of a humid / muggy feel during the overnight period. And winds will be light from the south east.
Tomorrow we'll still have a 20% chance of rain, according to this morning (Thursday) forecast models, but the possibility of rain looks more promising. We'll want the rain to hit us because it will relieve us from the oppressive heat, when it finally arrives. Temps will rise to the mid 90s, and the heat index will quickly rise back to 100 or more during the afternoon. Saturday the chances of rain go up to 60%, with a chance of T-Storms that could be severe. Next week, we cool significantly AFTER the rainfall...
