SHORT TERM
(Tonight through Friday night)
Issued at 318 PM CDT Wed Apr 23 2025

Showers and thunderstorms today have been mainly focused over southeast Texas with energy from a left over MCS. Activity has been more isolated over Louisiana as cloud cover has help limit daytime heating and instability.

Shower activity will gradually wind down this evening after sunset. With more stable conditions overnight, expect more low clouds and patchy fog.

Surface ridge to the east will continue to bring low level southerly flow and plenty of Gulf moisture into the forecast area for the next few days. Meanwhile, zonal pattern aloft will allow for weak perturbations to move across to interact with the Gulf moisture and any residual mesoscale surface boundaries and daytime heating to produce scattered showers and thunderstorms through Friday. At this time, parameters for severe weather are not too impressive. Heavy rainfall may be a factor, especially if the shower activity falls over locations that have received a decent amount of recent rainfall.

LONG TERM
(Saturday through next Tuesday)
Issued at 324 PM CDT Wed Apr 23 2025

Low level southerly flow and moisture will continue over the weekend into early next week. However, an upper level ridge is expected to build in from northern Old Mexico. This ridge will bring drier air in the mid levels to help cap the atmosphere and limit convection.

With the lack of convection and a continuation of low level moisture, hot and humid conditions, especially for April, can be expected in the long term.

Radar showing two clusters of TSRA, both affecting BPT and AEX for the next couple of hours. Elsewhere, VCTS left at LCH for any showers that develop ahead of the cluster over SE TX the next couple of hours. For LFT/ARA, not anticipating much convection to affect these terminals this afternoon/early evening. MVFR visibilities & ceilings expected by 08z, with intermittent IFR visibilities & ceilings between 09-13z at all sites. Expecting another round of TSRA between 18-24z Thursday for AEX highlighting with a PROB30 group for TSRA. Further south at BPT/LCH/LFT/ARA with lower chances of shower and thunderstorms, will only mention VCTS during this time period.
