A cold front Sunday afternoon will usher in a return of cold temperatures to start the work week. && .DISCUSSION... Issued at 1009 PM CST Thu Dec 4 2025 The dreary conditions will continue through Friday for SE Texas with mostly cloudy skies and chilly weather. Area will remain mostly rain-free through sunrise (other than some spotty areas of drizzle possible), but scattered light rain showers will return along the coast by daybreak with continued chances likely through Friday evening. Greatest chances of showers will be off the coast, but areas along and south of I-10 may see some light rainfall. The rainfall will be largely stratiform rain (a slow, steady rainfall), not convectively driven showers like typical SE Texas rainfall. Afternoon high temperatures will be in the low 50s across much of the region, but may struggle to rise out of the upper 40s if rain coverage is greater than expected. With overcast skies persisting into overnight Friday night into Saturday morning, low temperatures will be dropping into the low to mid 40s across much of the region and staying in the upper 40s to low 50s. The mostly cloudy skies will persist Saturday morning, but skies will begin to clear northwest to southeast through the day. The breaks in the clouds and a light southerly wind will bring high temperatures closer to normal - in the mid to to upper 60s. These warmer conditions will continue into Sunday with mostly sunny skies expected, and with areas along and south of I-10 likely climbing into the low to mid 70s. Enjoy your time with this milder weather because a dry cold front moving through the area Sunday afternoon/evening will lead to a return of cold temperatures to start the work week. Overnight lows will return to the upper 30s to mid 40s across much of the area Sunday night (and a breezy north wind will make it feel colder). High temperatures on Monday will be in the mid 50s to low 60s across the area. Dry conditions with a gradual warm-up is then expected through the remainder of the week. Fowler && .AVIATION... (12Z TAF Issuance) Issued at 530 AM CST Fri Dec 5 2025 Low cigs and isolated to scattered shra expected today. Best chance of shra will be from I-10 to the coast. Cig forecast is somewhat complicated today. Confidence is relatively high that there will be clouds in the IFR to low-end MVFR level. However, there is a chance that the deck could become scattered, at least occasionally, resulting in VFR conditions. For now, the forecast shows mostly MVFR cigs through the rest of today and into tonight. Most shra activity is expected to be over by 21Z. However, there may be another round of scattered shra by tomorrow morning near the coast. && .MARINE... Issued at 1009 PM CST Thu Dec 4 2025 Extended the Small Craft Advisory through late tonight as wind gusts up to 25kt persist, and small craft will likely need to exercise caution through Friday morning. Scattered to widespread light to occasionally moderate showers are expected to develop by daybreak and persist through Friday night. These showers will exit to the east by Saturday morning. Light northerly winds expected through early Saturday afternoon with winds veering to onshore by Saturday evening. These onshore winds will not last long as winds turn northwesterly Sunday afternoon following the passage of a dry cold front. Strong northwesterly winds of 20-25kt with gusts to 30kt develop Sunday evening and continue into Monday morning. These strong winds will also lead to seas of 5-7ft during this timeframe. Conditions improve through the day on Monday with light north to northeasterly winds expected by Monday night. Fowler && .PRELIMINARY POINT TEMPS/POPS...
