| Area Forecast Discussion National Weather Service Houston/Galveston TX 624am CDT Monday Mar 16 2026 Issued at 1156pm CDT Sunday Mar 15 2026 The cold front is currently about to exit the offshore Gulf waters and strong northerly winds are starting to ramp up over Southeast TX. We are observing winds at 20-25 with gusts of 30-40 mph inland. These speeds are expected to prevail into the morning hours as a 50-60 knot low level jet moves overhead behind the frontal passage tonight. The Wind Advisory will continue in effect through 6pm Monday. Make sure loose and light outdoor objects have been secured. Strong winds could also lead to power outages at times. Cold, dry air will also move in quickly behind the front tonight, with temperatures dropping into the upper 30s to mid 40s by sunrise. Taking into account the strong northerly winds, temperatures will feel closer to the upper 20s to mid 30s. Thus, make sure to bundle up during the early morning hours. Colder conditions prevail Monday, with sunny skies and highs in the 50s areawide. Very nice :P. The one thing we will have to monitor closely on Monday is the potential for elevated to critical fire weather conditions given how dry and windy we will be (more details on the Fire Weather Discussion below). Winds begin to relax by late afternoon to evening. Cold Air Advection will continue on Monday night and will give us the coldest temperatures for this week. The lows will be in the lower 30s (near freezing) over the Piney s, the mid 30s to lower 40s for the rest of the inland portions, and the mid to upper 40s along the coasts. Fair weather will prevail for the rest of the work week. Southerly flow will return Tuesday and continue into the rest of the work week, resulting in another warming trend with highs will be back in the 80s by Thursday and the upper 80s to lower 90s this weekend. Cotto Marine Issued at 1156pm CDT Sunday Mar 15 2026 As of midnight tonight, the cold front was exiting the offshore Gulf waters. Strong northerly winds of 30-35 knots and gusts of 40-50 knots are expected in the wake of the front. Seas will build to 8-15 feet. A Gale Warning is now in effect through Monday afternoon. Low water levels can be expected in the bays Monday morning. Winds will begin to relax Monday evening and seas will gradually subside Monday night into Tuesday. Light onshore winds return Tuesday night and continue Thursday. Winds may veer south- southwesterly Friday into the upcoming weekend. Cotto Fire Weather Issued at 1156pm CDT Sunday Mar 15 2026 Very dry air will filter across Southeast TX in the wake of Sunday's front. Expect elevated to critical fire weather conditions as afternoon RH values lower into the upper teens to lower 20s on Monday and northerly winds are around 20-25 mph with gusts of 25 to 35 mph. A Fire Weather Watch will be in effect for most of Southeast TX on Monday. Dry conditions prevail on Tuesday, but winds will veer southeasterly and be much lighter. RH values will begin to increase mid week into the end of the work week as south-southeasterly winds prevail and low level moisture recovers.
