cold front extends across the Gulf of Mexico, with areas of
thunderstorms lined up along it from east of Brownsville Texas to

coastal waters, but it is not expected to affect our land-based
Most weather models do indicate several weak low pressure areas
along this front. Per NHC, there is a low 20 percent chance for
tropical or subtropical development now through the end of the
After a dry day today and Thursday, expecting rain chances to
increase Friday into the weekend thanks to the frontal boundary in
the Gulf moving back northward towards the northern Gulf Coast. So
the highest rain chances will in general be higher along and south
of the I-10 corridor starting out Friday, but eventually it will
encompass our entire region over the weekend.
Temperatures will be 5 to 10 degrees below normal for overnight
lows thanks to the northerly flow today and tomorrow, and return
to near normal later this weekend.
a Small Craft Advisory is in place for the coastal waters, thanks
to northeasterly winds of 20 knots or stronger. This should
decrease by this afternoon.
Of note, as the frontal boundary moves back to the north later
this week and weekend, we could see a strong easterly wind set up
along the coast, which could signal an above normal tide
scenario, possibly causing some minor coastal flooding.
