Issued at 1259 PM CST Tue Dec 9 2025 With light onshore winds, higher dewpoints and mclr skies...look for some areas of fog to develop overnight. A weak, albeit dry, frontal boundary will sag into the area Wednesday and off the coast Wednesday evening. Other than a brief wind shift back to the north and a subtle drop in temps, most probably won`t even recognize it. Southeast winds resume Thursday afternoon, bringing a gradual return of Gulf moisture and warmer temperatures Friday and Saturday. Surface high pressure dropping into the nctl CONUS toward the Midwest and Mississippi Valley will send the next front into and through our region Saturday night and Sunday. Scattered showers and isolated storms appear to be a possibility in advance. Brunt of coldest air behind this front will bypass us to the e/ne, but we`ll see readings back into the 40s at night and 55-65 during the day into early next week. An approaching mid-upper trof should provide our next shot of some rainfall Tue-Wed of next week. 47 && .AVIATION... (12Z TAF Issuance) Issued at 518 AM CST Tue Dec 9 2025 Other than some patchy early morning fog, VFR conditions will prevail today. Winds will be light, becoming south then southwesterly. There could be patchy fog late tonight into early tomorrow morning. For now, mention of reduced vis has not been included in the TAFs for tomorrow morning.

We could see some patchy fog spill over across inland areas briefly spill over into the upper parts of the Houston Ship Channel late tonight and early Wednesday morning. A weak frontal boundary will be sagging into the water Wednesday evening, but it will be short lived with onshore winds resuming during the day Thursday. If water temperatures do not climb much between now and Saturday, we may see another brief round of sea fog develop Saturday evening and night in advance of another slightly stronger front expected Sunday morning. Scattered showers and isolated storms in advance of the front will end with its passage followed by moderate northeast winds in its wake.
