KEY MESSAGES
Issued at 242 PM Tue Jul 15 2025

- Lower rain chances through Thursday. Isolated showers and thunderstorms may still occur, in particular during the afternoon hours.

- Rain chances are expected to increase again late Thursday into early Saturday.

- Still monitoring the tropics (northeast & north central Gulf).

DISCUSSION
Issued at 242 PM CDT Tue Jul 15 2025

We might still have a chance for additional development of isolated to possibly scattered showers and thunderstorms through early this evening, although the GOES TPW imagery is already showing some drier air creeping into the Matagorda Bay region early this afternoon. For tonight, mostly tranquil conditions expected with low temperatures in the lower 70s over the Brazos Valley and Piney Woods region, the mid to upper 70s over areas near and south of I-10, and the lower 80s along the coasts.

The drier air will make its way further inland on Wednesday and stick around through Thursday, resulting in even lower chances of rain. The high temperatures could creep up a bit on Wednesday and may range in the mid 90s for several locations. Heat Indices are expected to range between 101 and 106 deg F, and hopefully, the drier air will help keep us out of a Heat Advisory for Wednesday.
Regardless, it is summertime and conditions are typically hot enough to cause heat stress if not taking the appropriate precautions.

Rain chances will be on the rise from late Thursday into Friday, as a disturbance or area of low pressure with higher levels of moisture moves in from the east or southeast (Refer to the Tropical discussion for more details on this disturbance). Our local PWs are expected to rise to 2.0-2.4 inches as this feature moves across our area and could result in periods of moderate to heavy rainfall at times. Rain chances will decrease Saturday into Sunday as the disturbance either weakens or moves out of SE TX and drier air moves in.

AVIATION
(00Z TAF Issuance)
Issued at 505 PM CDT Tue Jul 15 2025

Isolated afternoon showers/storms will taper off this evening as light and variable winds settle in across the region. Patchy fog and CIGS may develop over portions of the region during the early morning hours of Wednesday. MVFR conditions may develop with IFR FLs possible in some spots, mostly north of Houston. Conditions improve after daybreak with VFR largely dominating across the area. Southwest winds strengthen during the daytime, shifting south/southeast during the afternoon, then becoming light again in the evening.

MARINE
Issued at 242 PM CDT Tue Jul 15 2025

Light to occasionally moderate onshore winds and seas of 2 to 3 feet will continue for the next few days. We are expecting lower rain chances through Thursday as drier air filters across the region. From late Thursday into Friday, rain chances are expected to increase as a tropical disturbance moves into SE TX from the northern Gulf region. There still remains uncertainty regarding the development and track of this disturbance and more information will be known once the system moves into the Gulf waters. The 2PM EDT Tropical Weather Outlook, continued a 40% chance of formation through the next 48 hours. Please continue to monitor the upcoming forecasts.

Cotto

TROPICAL
Issued at 242 PM CDT Tue Jul 15 2025

Based on the 2PM Tropical Weather Outlook, an area of low pressure is currently moving east over north central portions of FL and is expected to move into the northeastern Gulf waters on Wednesday. Environmental conditions may be favorable for further development as the system continues moves into the north central portions of the Gulf and a tropical depression could form as it approaches the coast of LA. There's still uncertainty regarding the strength and track of this system and more information will be known once the system moves into the Gulf waters. Regardless of formation, the system could bring periods of moderate to heavy rainfall over portions of Southeast TX from late Thursday into late Friday.

Please continue to monitor the progress of this system as well as the latest forecasts.
