Thursday Night's Outlook

Friday's Outlook

Heavy Rain Late Sun/Mon

A weakening front will move across Southeast Texas on Friday. The heavy rain threat will be focused mainly north and west of our area, though some portions of Southeast Texas can't yet rule out isolated issues if a stronger storm occurs over a spot vulnerable to flooding. The front will continue to weaken as it moves towards the coast, and the heavy rain threat will begin to wane as it moves through the area.

Scattered showers/storms over portions of the Brazos Valley/Piney Woods overnight. Locally heavy rainfall possible. Patchy fog possible near and south of I-10 during the late night to early morning hours. Lows 65-70°.

Near record high temperatures again around and south of the Houston metro area with highs in the low to mid 80s. Scattered showers/storms mainly north of I-10 as a weak cold front approaches. Low temperatures range from the upper 50s to upper 60s as the cold front begins to push in overnight. Shower/storm chances continue overnight along the front.

Scattered showers and thunderstorms are expected late Sunday into Monday night as another disturbance and associated cold front pushes through Southeast TX. Locally heavy rainfall could lead to instances of minor street flooding. Marginal Risk (level 1 of 4) of Excessive Rainfall for the Brazos Valley/Piney Woods for late Sunday. Slight Risk (level 2 of 4) of Excessive Rainfall for portions of the Piney Woods and a Marginal Risk (level 1 of 4) for the remainder of Southeast Texas for Monday/Monday night.
