DISCUSSION

Issued at 1032 PM CST Thu Dec 4 2025

In the wake of the cold front, overcast skies and cool temperatures are forecast to continue Friday. Persistent CAA and limited daytime heating will likely keep high temperatures Friday afternoon in the 60s. A coastal trough developing offshore will provide a low to moderate (15-30%) chance for light rain or drizzle through Friday night.

Cloud cover will begin to decrease Saturday as the overrunning pattern begins to break down, likely allowing high temperatures to increase into the 70s Saturday afternoon and into the 80s Sunday afternoon. A deeper cold front looks to move through the area Sunday evening, bringing mostly clear skies and stronger northerly winds by Sunday night. This will likely allow low temperatures to drop back into the 40s to low 50s going into early next week. By mid-week, southeasterly winds look to return, which will allow temperatures to gradually increase through the later half of the week.

AVIATION

(12Z TAFS) Issued at 539 AM CST Fri Dec 5 2025

The Small Craft Advisory will continue through Friday morning, as conditions begin to improve Friday morning. Generally favorable conditions will likely then persist through Sunday morning. A strong cold front Sunday will likely bring another round hazardous marine conditions Sunday night into Monday. An additional Small Craft Advisory will likely be needed for that time period. Conditions look to improve by Monday afternoon, with favorable conditions continuing through the remainder of the period.
