.SHORT TERM...
(This evening through Saturday night)
Issued at 218 PM CDT Fri May 2 2025

Tonight, a frontal system is expected to move through the area
and linger into the daytime hours on Saturday. There is still some
uncertainty in the models, especially relating to the strength of
this line. But generally, severe storms will be expected as it
moves through the area, especially for locations north of I-10/12.
We are outlooked in an enhanced to slight risk of severe weather
by SPC. Gusty winds (60+mph) will be the main threats, but a
tornado cannot be ruled out, especially for the northwesternmost
areas like SW MS. Locally heavy rainfall will also be possible,
especially for urban locations. The timing of this system looks to
be a little earlier in the evening than previous model runs have
indicated. Generally, the line is expected to be approaching our
area by around 7-8pm and move through our area entirely by
Saturday morning. There are some indications that some scattered
rain and showers could linger into the daytime hours on Saturday,
but these storms would not be severe at that point and we are not
outlooked in any risk area for Saturday.

Saturday evening into Sunday morning will be dry once these storms
move out of the area by sunset Saturday. MSW

&&

.LONG TERM...
(Sunday through Thursday night)
Issued at 218 PM CDT Fri May 2 2025

Sunday through Tuesday, conditions look fairly dry across the
area after the passage of this cold front, looking at the models.
Highs will be in the mid 80s Sunday, Monday, and Tuesday. An upper
level shortwave system will be approaching the area on Tuesday and
will linger into Wednesday and Thursday. This system will enhance
rain chances for the region. It is a little far out for details,
but strong storms and locally heavy rainfall will likely be
possible. We will keep monitoring for changes as we go through the
next few days. MSW

&&

.AVIATION...
(00Z TAFS)
Issued at 704 PM CDT Fri May 2 2025

Main concern overnight will be the potential for scattered
SHRA/TSRA, which could produce MVFR to locally IFR conditions.
There could be a lull between current development, which has been
triggered more by heating that will diminish shortly, and storms
ahead of the frontal boundary which may not occur until well after
midnight. Any significant threat of storms should diminish by
late morning or early afternoon Saturday. Behind the frontal
passage, VFR is expected.

&&

.MARINE...
Issued at 218 PM CDT Fri May 2 2025

Winds will be benign, but moderate (10-15kts) and southerly
across the marine waters this weekend. Winds Monday through mid-
week will be easterly and moderate (10-15kts). MSW
