An upper-level low will move out of the Southern Plains and into the Mississippi River Valley tomorrow into Wednesday; this will bring an associated surface low and cold front east.
The moisture will result in widespread, soaking rainfall pushing from west to east across East Texas, North-Central Louisiana, and Northern Mississippi and Alabama tomorrow – Wednesday.
It will also result in scattered showers and thunderstorms across the remainder of Louisiana, Mississippi, Alabama, and the Western Florida Panhandle.
Generally, rainfall accumulations between 1 – 3″ are expected across East Texas, North-Central Louisiana, and Northern Mississippi and Alabama, with some locally higher accumulations possible. Accumulations between 0.10″ – 0.50″ are anticipated for the remainder of Louisiana, Mississippi, Alabama, and the Western Florida Panhandle.
There will be some potential for a few isolated strong to severe storms across East Texas and parts of North-Central Louisiana and Mississippi tomorrow, and North-Central Mississippi (again) and North-Central Alabama Wednesday.
Overall, the severe weather threat is low (“marginal” per the Storm Prediction Center), as instability will be lacking. The time-frame of when an isolated severe storm or two might pop both tomorrow would be the afternoon/early evening hours, and morning through early afternoon hours Wednesday.
The main concern with any severe storms that manage to develop will be some damaging wind gusts or a brief, isolated tornado or two.
