Area Forecast Discussion National Weather Service Lake Charles LA 957 AM CDT Wed Apr 30 2025
New UPDATE, MARINE
KEY MESSAGES
- A few showers and storms possible this afternoon over interior Southeast Texas
- The next chance of showers and thunderstorms expected Thursday through Saturday as a cool front approaches and moves across the area.
- Above normal temperatures will continue through Friday, returning to near normal for the weekend.
UPDATE
Issued at 956 AM CDT Wed Apr 30 2025
Small craft advisory now in effect through tonight.
SHORT TERM
(Today through Friday night)
Issued at 303 AM CDT Wed Apr 30 2025
Ridging at the surface and aloft is centered just near to just east of north FL this morning. A trough aloft extends from West TX into the plains. The local area is roughly between these systems.
Today will be similar to yesterday with a few spotty sprinkles this morning although the upper trough will shift slightly east and northeast today which may allow for a few isolated to widely scattered afternoon showers and storms across interior SE TX and the Sabine watershed. The pressure gradient will keep the onshore gusty at times. Winds will approach wind adv criteria this afternoon across the I-10 corridor to the coast. Temps will also be comparable to yesterday.
Thursday rain chances will increase as the aforementioned upper disturbance lifts out and the upper pattern becomes more zonal but somewhat diffluent. SPC has highlighted interior SE TX through Cen LA as having a marginal risk of severe storms and excessive rain. Conditions will remain warm and humid.
By Friday another upper disturbance moves southeast into the central sections of the country. This will drive a cold front south to the area. An increase in lift and the already in place warm and humid conditions will allow for an increase in convection. A marginal to slight risk of severe weather is anticipated away from the coast. There is also a marginal risk of excessive rain Friday.
LONG TERM
(Saturday through Wednesday)
Issued at 303 AM CDT Wed Apr 30 2025
Rain chances will linger into Saturday but decrease Saturday night. Cooler and drier conditions will filter in behind the cold front. Near normal temperatures and dry weather will remain in place into early next week.
AVIATION
(12Z TAFS)
Issued at 556 AM CDT Wed Apr 30 2025
Very patchy MVFR ceilings and thin br will linger for an hour after sunrise but improve after that. VFR conditions are then anticipated through the remainder of the day and into the evening.
MVFR ceilings will likely develop again late tonight to the end of the period. Gusty S-SE winds are expected from late morning through the afternoon.
