FXUS64 KHGX 142310 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 510 PM CST Sun Dec 14 2025 ...New AVIATION... .KEY MESSAGES... - Freezing temperatures are expected for a good part of SE TX overnight. Hazardous marine conditions continue, but will begin to improve late tonight. - Gradual warm-up into midweek. - Chances for scattered showers return to the forecast late Tuesday night through Wednesday night. Next front penciled in for Thursday afternoon/night. && .DISCUSSION... Issued at 1252 PM CST Sun Dec 14 2025 In the wake of last night's cold front, temperatures are between 15-30 degrees colder than what we had this time yesterday. Skies will clear from the east/northeast for the remainder of the day and tonight and winds will gradually diminish. Combination of both should allow for freezing overnight lows for a good part of SE Tx tonight. The Freeze Watch previously in effect for locations that haven't received their first winter freeze has been converted to a Freeze Warning. Also threw in Wharton and northern Brazoria Counties where guidance trended a touch lower with temps. Kept Galveston County out for now, as a NE wind trajectory off the warmer bay should keep temps a few degrees above the freezing mark (but we'll monitor trends). Gradual warm-up will begin Monday as cold high pressure area starts moving further to our east and winds swing back around to a e/se direction off the Gulf. Highs/lows will transition upward on a daily basis and back into the 70s/50s by midweek. Mid-upper trof will pass across the state Tue night-Wednesday night. We should see enough of a moisture return by then for some scattered shower and/or isolated thunderstorm development. The next cold front, Pacific in origin and not nearly impressive as the current one, is penciled in for Thursday afternoon & evening followed by a quick return of the warm muggies heading into next weekend. 47 && .AVIATION... (00Z TAF Issuance) Issued at 456 PM CST Sun Dec 14 2025 VFR conditions expected through the end of the TAF period. N-NE winds currently at 08-12KTS with gusts of around 20KTS for most sites, slightly stronger at GLS. Winds will continue to relax tonight to 04-06KTS and turn ENE to E on Mon (late afternoon or evening) as high pressure moves over SE Texas. Cotto && .MARINE... Issued at 1253 PM CST Sun Dec 14 2025 Moderate-strong north to northeast winds 20 to 35 knots and elevated seas will continue into the overnight hours before slowly diminishing after midnight. Small Craft Advsy remains in effect for the bays, and will transition the Gale Warning in the Gulf back down to a SCA later this evening once gusts begin to subside. Continued improvement is anticipated Monday. Winds will gradually veer around to the east and southeast as high pressure tracks away from the region. Light to moderate onshore flow will then prevail through Thursday. We will need to be on the lookout for some sea fog development Wednesday and Thursday in between bouts of scattered showers and isolated thunderstorms. The next front is forecast to push off the coast Thursday night. 47 && .PRELIMINARY POINT TEMPS/POPS...
