.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.

The Small Craft Advisory will continue through Friday morning, as

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.
