DISCUSSION

Issued at 1214 AM CDT Fri Apr 3 2026

Mostly tranquil conditions are expected tonight with cloudy skies and southeast winds at 7-10 mph. The overnight lows will be in the upper 60s over the Piney Woods region and the lower 70s for the rest of Southeast TX. Winds should be strong enough to limit fog development for most of the region.

Friday will start off cloudy, but we might see some breaks in the clouds during the afternoon hours before becoming cloudy again later in the evening. The highs will be a few degrees warmer, generally in the lower to mid 80s inland and the upper 70s to lower 80s over the coastal locations. There could be some isolated to scattered showers and thunderstorms during the day, mainly for areas near and east of I-45 as well as the coasts. It is expected to be breezy again with southeast winds ranging between 12-20 mph with gusts of around 25 mph on occasion.

We will begin to see some showers and thunderstorms moving into the Brazos Valley and Piney Woods region Friday night as an upper level trough moves through the Plains and a cold front pushes across central TX. Activity is to increase and expand southward during the overnight hours and Saturday morning as the front approaches Southeast TX. Additional shower and thunderstorm development is expected ahead and along the front, which is progged to move across our region from the afternoon to early night hours. Some of the thunderstorms could become strong to severe and SPC has placed most of Southeast TX in a Marginal Risk (level 1 of 5). The primary hazards at this time are damaging winds and hail, although the chance for a tornado cannot be ruled out. Make sure to have multiple ways of receiving weather updates and warnings.

The front is expected to push into the Gulf waters near midnight, however, rain chances could continue into the overnight hours possibly due to isentropic lifting. We will start to feel those cooler temperatures Saturday night with lows in the lower 50s to lower 60s. Very pleasant temperatures are expected on Sunday with highs in the upper 60s to lower 70s areawide. Additional isolated to scattered rain chances are possible Sunday into Monday morning as a weak shortwave moves across TX. The best chances for rain on Sunday through Monday morning are focused over areas near and south of I-10 and the Gulf waters. Drier conditions will a gradual warming trend are expected Monday afternoon through the mid-week period.

AVIATION

(12Z TAF Issuance) Issued at 548 AM CDT Fri Apr 3 2026

MVFR ceilings this morning should lift in the mid morning hours and most locations should be VFR for the remainder of the day. There will probably be some spotty shra, and maybe an isolated tstm, around...but confidence in terms of specific locations/timing is low so opted not to mention attm. May need an amendment or two should a cell pop up near a terminal. Otherwise, gradient looks a bit tighter today and am anticipating gusty SSE winds 13-26kt into the evening. MVFR, and possibly IFR stratus fills back in this evening and overnight. 47
