Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
fog has retreated out of the bay this morning, but will linger in the gulf during the day. A general repeat scenario is anticipated through the weekend. Otherwise, light onshore winds and low seas will prevail into early next week. A weak, nearly stalled front may meander around the coast Sunday night and Monday followed by more prevalent onshore winds Tuesday and Wednesday. Another cold front is expected Wednesday night. This one appears to have a better chance of pushing off the coast.

SHORT TERM
(Today through Sunday Night)
Issued at 238 AM CST Sat Feb 8 2025
Technically we are still in Winter, but thermometers have clearly missed that memo as we are experiencing late Spring-like weather the past few days that will continue through most of the short term. High temperatures this afternoon will reach near record- breaking levels with highs in the low to mid 80s for most of the region with parts of the Brazos Valley reaching the upper 80s (this is closer to the normal highs for the end of April/beginning of May). Overnight lows tonight will be in the mid to upper 60s, which is actually what our normal high temperatures are for this time of year.
There will be a slow moving, weak cold front sliding in from the north on Sunday that will begin to usher in some cooler conditions towards the evening and overnight hours - depending on how far south the front makes it before stalling. Global models have the front stalling near the Piney Woods on Sunday and thus keeping most of the region in our warm, moist airmass. However, hires models are now within range for the FROPA and some of these do have the front making it to the the I-10 corridor by sunset Sunday. So temperatures on Sunday will largely be dependent on the speed of the front, and southwards extend of the front before it stalls. Do think this will be a very slow moving cold front, so have sided with warmer solutions for daytime temperatures on Sunday with areas south of Conroe getting into the upper 70s to low 80s while areas to the north will stick to the mid-70s.
Temperatures Sunday night become much more uncertain, so stuck with a 75/25 blend of NBM and NAM12.
There could be some isolated showers developing along the cold front as it moves through the area on Sunday, but any showers that do form will be light and quickly dissipate. The other main weather story remains to be the persistent sea fog down along the coast. Expect continued widespread, dense fog in the southern parts of the bays and nearshore waters overnight and patchy fog during the daytime hours. More on this in the Marine discussion below.

LONG TERM
(Monday through Friday)
Issued at 238 AM CST Sat Feb 8 2025
The shallow and weak cold front will be meandering along the coastal zones or offshore waters by early Monday. Mostly cloudy skies and a few light showers will still be possible during the day, especially near the sfc boundary.
Tuesday and Wednesday will feature a higher chance of showers and storms as multiple disturbances embedded into the quasi-zonal flow aloft move through, pushing the sfc boundary further off the coast. Increasing moisture and forcing ahead of these vorticity maxes aloft will lead to more widespread rain with a few embedded thunderstorms. Given the potential for a quasi-stationary boundary over Southeast TX, training storms will be possible. Therefore, localized heavy rain will also be possible, mainly north of I-10 as highlighted by the WPC's Day 4 excessive rainfall outlook.
Rain and storm chances gradually decrease by late Wednesday as a sfc high builds over the Plains. A cooling trend will follow the frontal passage with high temperatures in the 50s and 60s Thursday and Friday. Seasonable temperatures return towards the end of the long term with highs reaching the low 70s. Warm air advection along with a developing sfc low over the southern Plains may approach the upcoming weekend, potentially bringing another round of showers and storms.

AVIATION
(18Z TAF Issuance)
Issued at 1130 AM CST Sat Feb 8 2025
Ceilings are scattering out inland as we get some mixing. Expect VFR conditions with somewhat breezy ssw winds 12g24kt today.
Closer to the coast, fog has mainly burned off but expect some MVFR stratus to linger. This evening and overnight we anticipate that a mix of low end MVFR and IFR ceilings will fill back in...as will the sea fog for coastal sites. A slow moving, weak frontal boundary will be sagging into the area late tonight (10z or so CLL) then possibly crawl to the IAH area by sunset. Can't rule out an isolated shra, but chances not high enough to include in the TAFS. 47
MARINE
Issued at 238 AM CST Sat Feb 8 2025
Sea fog will continue to be the main marine concern through at least early next week. Patchy to areas of dense fog will continue along the nearshore waters and Bays through most of the day, eroding by midday across the Bays. The same scenario is expected tonight with fog and low clouds. A weak surface frontal boundary will enter the coastal waters by early Monday, before stalling or meandering across the region through mid-week. The best chance of showers and storms return Tuesday and Wednesday as the aforementioned front finally moves well offshore. Light to moderate onshore winds and low seas will persist into early next week.
