No major changes in the forecast this afternoon. High pressure
will shift east over the next few days and this will allow for
some moderation in the temperatures. We will nicely rebound to
near 70 for a high on Sunday. Not expecting much in the way of
rainfall over the few days. Model guidance suggests a weak cold
front moving through the area on Monday. This should not have an
impact in the forecast as the atmosphere is relatively dry. There
may be a few showers Monday as it pushes through, but the greater
chance of rain still looks to come by late next week. Models still
point to a shortwave will moving across the area on Thanksgiving
Day. The ECMWF and now the GFS has most of the rain remaining
offshore. Have not made major changes in POPs this forecast.
Clouds/precipitation likely to hold high temperatures down on
Thanksgiving Day, otherwise temperatures should be near to above
normal for the extended period. Ensemble numbers from both GFS and
ECMWF don't show much spread on temperatures between their
members, so haven't had to make much in the way of adjustments.
Mostly clear skies and good visibility will mean VFR conditions
should prevail through Sunday afternoon. The exception will be at
KHUM, KBTR, KHDC KMCB and KASD where some patchy fog may
occasionally restrict the visibility into the 4 to 5 mile range from
09 to 14z Sunday morning. Winds are expected to remain generally
Surface high over the central Gulf coast region will remain over the
region through the weekend into Monday. As a result, east to
northeast winds around 10 knots or less and seas 2 feet or less
across all waters through Monday. Northeast to east winds are
expected to rise into the 10 to 15 knots range across western waters
Tuesday and 15 to 20 knots over western waters on Wednesday as an
inverted trough of low pressure develops off the Texas coast. 18
