DISCUSSION

Issued at 1123 PM CDT Wed Apr 1 2026

Skies will be mostly cloudy during the overnight to early morning hours with lows in the upper 60s to lower 70s over Southeast TX. The local pressure gradient will remain tight and the low level jet will strengthen overnight, maintaining fairly breezy conditions over much of Southeast TX. This will limit fog development for much of the area. We could see a few streamer showers moving in from the Gulf before sunrise.

A mid-upper level trough moving through the Plains tonight into Thursday morning will fire up some storms over the northern and central portions of TX. These showers and thunderstorms are expected to push into the Brazos Valley and Piney Woods region around sunrise time and move southward during the afternoon hours. Some showers could produces periods of moderate to heavy rainfall, but significant flooding is not expected at this time. If anything, we could see some ponding of water along roadways and low lying areas. Most of the activity is expected to be focused over areas near and north of I-10, thus, the coast may not see much of this activity. The highs will be mainly in the lower 80s, thanks to the rainfall and cloudy skies. Showers and thunderstorms will dissipate during the late afternoon to early evening hours. Skies will remain cloudy on Thursday night with lows in the staying in the upper 60s to lower 70s.

The day will start off cloudy on Friday, gradually becoming partly cloudy later in the afternoon. We could see some showers and thunderstorms during the day, mainly for areas near and east of I-45. The highs will be warming back into the mid to upper 80s for most of the inland portions and the upper 70s to lower 80s over the coasts. The day will be breezy again with Southeast winds ranging between 12-20 mph with gusts of around 25 mph.

Showers and thunderstorms are possible over the Brazos Valley and Piney Woods region late Friday night into early Saturday an upper level trough moves through the Plains and a cold front pushes across central TX. Activity will expand southward and intensify during the afternoon hours as the front pushes across Southeast TX and slows down as it nears the coastal counties. There are some inconsistencies with when the rain ends after the frontal passage. The GFS continues to carry rain chances into Sunday, possibly due to isentropic lifting, while the ECMWF has a drier solution. We will have some cooler temperatures on Saturday with this activity, with highs possibly in the upper 70s over the Brazos Valley and Piney Woods region and the lower to mid 80s elsewhere. Even cooler conditions are expected Sunday, as highs range in the upper 60s to lower 70s for much of the area. Drier conditions with a gradual warming trend is expected early next week. Cotto

(12Z TAFs) Issued at 610 AM CDT Thu Apr 2 2026

Band of showers and isolated tstms will skirt ewd across northern parts of the area this morning. Ongoing MVFR ceilings will gradually lift back into VFR territory in the late morning and early afternoon along with breezy SSE winds as rain coverage diminishes. MVFR stratus looks to return the the region from south to north beginning in the early evening hours. Though probably not as gusty, winds should still remain up overnight, but if speeds decide to diminish just enough toward Friday morning, it's not out of the questions we could see some brief IFR conditions at times. 47
