FXUS64 KHGX 172008 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 208 PM CST Wed Dec 17 2025 ...New DISCUSSION, MARINE... .KEY MESSAGES... - Scattered rain shower activity to taper later this afternoon and evening. - Areas of dense fog possible tonight into tomorrow morning. - After a brief cool down on Friday, expect generally warmer than normal conditions this weekend into early next week. Record breaking warmth is possible. && .DISCUSSION... Issued at 1136 AM CST Wed Dec 17 2025 Scattered showers will continue into the afternoon across our southern and coastal counties. More isolated activity is expected farther north / inland. Could not rule out some isolated showers occuring into the overnight hours. As we head into the overnight hours, the primary concern will be areas of fog. Fog may be dense at times late tonight into tomorrow morning. Any fog is expected to break by mid-morning. A cold front will approach the region on Thursday. Southwest flow and warm temperatures are expected ahead of the front, with highs generally in the mid/upper 70s. The front reaches our northern counties Thursday afternoon, moving offshore by the evening. Gusty north to northeast winds, drier air, and falling temperatures are expected in the front's wake Thursday night. The air mass in place on Friday will feature seasonably cool temperatures, with highs generally in the 60s and lows mostly in the 40s. But the seasonably cool temperatures will not be long for this world due to the coming warm pattern change lurking in the longer range. By the weekend into early next week, anomalous ridging coupled with onshore low-level flow will result in an increasingly warm and humid regime. It appears afternoon temperatures will easily be well into the 70s during the Saturday-Tuesday time frame. And given the strength of the ridge, we could have days reach the low 80s, which would place us near record terriroty. So for those yearning for sweater weather leading up to Christmas, it appears you'll have to live with t-shirt and flip flop weather instead. && .AVIATION...
