DISCUSSION

Issued at 1136 PM CST Mon Dec 15 2025

With onshore flow back in place, we should see temperatures warm up as moisture returns. As PWs climb back above 1 inch another mid-upper level trough will swing through the state tonight into Wednesday, bringing scattered showers/storms back into the forecast. With any breaks in this rainfall, we'll also need to keep an eye out for sea fog along the coast beginning as early as later tonight/Wednesday morning. Wednesday night into Thursday morning will be the main timeframe to watch for sea fog due to lower rain chances and stronger moisture moving in from the gulf. The next cold front will push through the area Thursday afternoon/evening, resulting in another brief cool down. This cool down won't be as impressive as with the previous front with lows for Friday morning anticipated to drop into the upper 30s/lower 50s.

Onshore flow is anticipated to quickly return Friday night with temperatures warming up once again through the weekend into early next week. Highs this weekend will are currently slated to reach the 70s/lower 80s with lows in the upper 40s/60s. Sea fog may also develop along the coast during this period as well, spilling inland during the overnight/early morning hours.

Issued at 1136 PM CST Mon Dec 15 2025

Light to moderate southeasterly winds are expected through mid week. As moisture funnels into the area, scattered showers will return by later this evening. In between showers, we'll need to watch out for sea fog tonight through Wednesday morning at the absolute earliest. Wednesday night into Thursday will be the main time frame to watch for sea fog, as conditions appear more favorable. A cold front should push off the coast Thursday night with caution flags and Small Craft Advisories possible in it's wake. Winds quickly shift easterly on Friday, then southeasterly Friday night into the weekend. With the return of onshore flow, we'll have to watch for sea fog as early as Saturday morning.
