Updated at 1123 AM CST Tue Dec 9 2025 - Warming trend through the week ahead of the next cold front. - Dense morning fog expected by midweek. && .DISCUSSION... Issued at 1123 AM CST Tue Dec 9 2025 Stable conditions will prevail through much of of the work week, with little change from the previous forecast cycle. A weak front and a reinforcing surge of high pressure are forecast to slide across the region late Wednesday into Thursday, though its local influence will be limited to an onshore wind shift and a brief hindrance to warming temperatures. Given the very limited available moisture, no precipitation is expected with the boundary. Moisture return increases late in the week as the aforementioned surface high shifts east and southerly surface flow strengthens. As humidity increases, highs will moderate out into upper 70s to low 80s with overnight lows trending milder beginning Thursday night, rising to the mid-50s to low 60s. The uptick in boundary layer moisture may also promote fog development beginning early tomorrow morning and continuing through late week. By this weekend, attention turns to our next cold front, through model guidance continues to differ slightly regarding timing and strength. Timing has shifted later in the forecast period to late Sunday into early Monday. Nonetheless, the weekend into early next week appears to be the next meaningful opportunity for rain, with low chances (20-30%) for coastal showers as early as Friday night into Saturday and broader chances (20-50%) increasing into late weekend or early next week depending on the frontal progression and moisture return. && .AVIATION... (18Z TAFS) Issued at 1056 AM CST Tue Dec 9 2025 VFR conditions will prevail through a majority of this forecast period. South-southwesterly winds will remain below 10 knots under clear skies. Probabilities of fog developing over the inland Coastal Plains and portions of the southern Brush Country have increased this cycle, primarily impacting VCT/ALI/LRD from 10-14Z Wednesday morning. Included TEMPO groups this forecast to denote this. && .MARINE... Issued at 1123 AM CST Tue Dec 9 2025 Onshore flow returns this afternoon, remaining at gentle to moderate (BF 3-4) levels through late week. There is a low chance for patchy sea fog overnight tonight before a disturbance moves through late Wednesday. A better potential for sea fog may come over the weekend ahead of the next front. Confidence remains low at this time. A low to medium chance (20-50%) chance of showers and thunderstorms will accompany the aforementioned weekend front. && .FIRE WEATHER... Issued at 1123 AM CST Tue Dec 9 2025 Minimum relative humidity values will dip below 30% through Wednesday across portions of the Brush Country. However, due to generally low ERCs in the 50-70th percentile and weak winds of 5-10 mph, elevated fire weather conditions remain negligible at this time. && .PRELIMINARY POINT TEMPS/POPS...
