KEY MESSAGES

- Widespread showers and thunderstorms brought 1-3" of rain across portions of the Brazos Valley and Piney Woods region this morning.

- Daily chances of scattered showers and isolated thunderstorms with the greatest chances late Saturday into Sunday as a cold front moves into/through the area. - Unseasonably warm weather persists through Saturday, then the cold front ushers in cooler, more seasonal temperatures by Sunday and extending into early next week.

- Risk of moderate to strong rip currents today into the weekend.

DISCUSSION

Issued at 201 PM CDT Thu Apr 2 2026

Widespread showers and thunderstorms occurred over the Brazos Valley and Piney Woods region earlier today as a weak disturbance slide across the region. Rainfall totals through 2pm shows a swath of 1-3" from Burleson up through Houston County, and then around 0.1-0.5" between Conroe and Huntsville, and less than 0.1" south of Conroe. Some isolated thunderstorms will continue through the rest of the afternoon, but overall activity appears to be waning. Rain chances will then be low through Friday, though some isolated streamer showers may develop during the late morning and afternoon hours as onshore flow increases moistures across the region.

Our next chance of rain arrives Saturday as a cold front begins to move through the area, increasing moisture (PWATs up to 1.8" by the afternoon hours) across the area. Widely scattered showers and isolated thunderstorms will be possible by late Saturday morning, increasing in coverage through the afternoon/evening as the front begins to slides through the region. The cold front is expected to slowly pass through the region through Sunday morning, and then possibly stalling along the coast for a period of time on Sunday. Lingering showers and storms may be possible south of I-10 through Sunday morning or afternoon as passing disturbances aloft redevelop activity along the front. An isolated strong to severe thunderstorm is also possible Saturday into Saturday night, with wind gusts being the primary concern (SPC has a Marginal Risk for Severe Thunderstorms (level 1 of 5) for Saturday for most of SE Texas). WPC maintains a Marginal Risk (level 1 of 4) for excessive rainfall across all of SE Texas for Saturday into Saturday night as localized downpours fueled by the increased moisture becomes possible. Areas that saw the heaviest rainfall today (Brazos Valley/Piney Woods) may have a greater risk of minor urban and small stream flooding on Saturday/Saturday night if those downpours occur over the same areas. High pressure eventually moves in behind the cold front, pushing the stalled cold front out of the region Sunday night. Rain chances then remain minimal through at least midweek next week.

High temperatures will remain in the low to mid 80s through Friday across with overnight lows in the low to mid 70s. Saturday will be a transition day as the cold front slides through the region, and temperatures will largely be dependent on the timing of the cold front. As of now, looks like areas along and south of I-10 will have enough heating during the day to bring temperatures up to the low to mid 80s on Saturday, while areas to the north will likely stay in the upper 70s. A slower cold front would mean warmer temperatures around the region, and a faster front would cool afternoon high temperatures by a few degrees. Overnight low temperatures Saturday night will be down into the mid 50s to low 60s for much of the region as cooler air filters in behind the front. High temperatures in the upper 60s to low 70s are expected Sunday and Monday, then a gradual warm-up is expected through the remainder of the week with highs in the mid 70s by Tuesday, upper 70s on Wednesday, and then back into the low 80s by Thursday or Friday. While overnight lows will remain on the chillier side Sunday night with temperatures down into the low to mid 50s across the region, Monday night will be the coolest night of the week thanks to clearing skies and light winds with overnight lows down into the mid to upper 40s for areas north and west of the Houston Metro. An increase in overnight temperatures are then expected through the remainder of the week rising from 50s on Tuesday night, upper 50s to low 60s Wednesday night, and then mid 60s by Thursday night.

Convective activity has dissipated, but gusty southeasterly winds will persist through the evening. MVFR ceilings will begin filling in from the south near or just after sunset from south to north and encompass all of Southeast TX by 06Z/Friday. Winds remain elevated overnight, so the potential for fog is slim to none. There is potential for intermittent periods of IFR ceilings especially south of I-10 early Friday morning. Reduced ceilings last into the late morning/early afternoon hours before lifting to VFR as southeasterly winds pick up once again with gusts near 25 kt through the afternoon. Isolated to scattered showers are expected to develop around 15Z/Friday...the greatest confidence is south of I-10 and along/east of the I-45 corridor. The coverage looks to be rather sporadic though, so this has been covered with PROB30's for now. Look for another round of IFR/MVFR ceilings Friday evening.

Onshore flow will persist through Saturday. While the onshore winds are light this afternoon (around 10-15kt), there will be an increase overnight to around 15-20kt tonight into Friday resulting in a need for small craft to exercise caution. Some gusts to 25kt will be possible in the coastal waters late tonight into Friday afternoon. Seas will remain between 3-5ft, occasionally 6ft, through Saturday.

A cold front is expected to slowly push through the coastal waters late Saturday night through Sunday morning ushering in moderate to strong northeasterly winds in it's wake that persists through Monday morning. The elevated winds will also lead to building seas to 5-8ft. Small Craft Advisories will likely be needed by sunrise Sunday and continue into Monday morning for the bays, and then Monday afternoon for the coastal waters as seas are slow to fall. Scattered showers and thunderstorms are expected ahead of and along the cold front beginning Saturday evening and continuing through Sunday afternoon as the front is slow to exit the waters.

There will also be a moderate to high risk of strong rip currents through at least Saturday thanks to the persist onshore winds.
