High pressure has continued to build in today with most of the rain in Alabama this afternoon, but a few storms have fired in East Mississippi. As high pressure approaches tonight and then tomorrow, it is bringing the warmest air of the season. As of 2pm, it is 98 in Bastrop, LA and 94 in Vicksburg. We won't hit 98, but mid 90s look solid area wide.
As high pressure arrives, the sinking air associated with it will limit rain chances for most of East Mississippi, making the best chance at rain tomorrow in our West Alabama counties, especially our eastern most locations (like Demopolis). Rain chances remain small for Thursday as well before an area of low pressure rounds the southern side of the high in the Gulf of Mexico and starts to reintroduce rain chances for all of us for the weekend.
Highs look to remain at or above 94 the next 7 days. Now, the only real impact on highs will be any storms that form prior to about 3pm, and they will keep highs from getting to the mid 90s. Otherwise, heat and humidity abound the next 7 days. Tomorrow and Thursday especially could be oppressive with heat indices reaching 105 in the afternoon hours.
