.DISCUSSION...
A much quieter morning across SE TX. The last line of convection
(likely associated with the 85H front) has moved off to the E/SE
and skies are clear across the CWA. Main forecast issue looks to
be temps these next few days given the moderate/weak CAA develop-
ing in the wake of the front. Lower/mid 80s max temps should pre-
vail this afternoon with lows tonight in the lower 60s inland to
the lower 70s along the coast. Warmer temps expected by the week-
end with low 90s possible starting Fri afternoon.

The upper ridging over the region (today/Thu) will be flattening
by Fri as the main low/trof moves off the NE coast. The building
ridge over the west coast will help maintain the zonal flow over
the state through the weekend. The return of onshore winds along
with Gulf moisture could produce some isolated showers along the
coast late Sat night, but the main focus should be further north
as a weak cold front moves down from the Southern Plains. Models
have been indicating that this boundary could be the focus for a
period of wet/active weather for SE TX beginning Sun night on in-
to perhaps the middle of next week as a series of shortwaves app-
roach from the west. (That this time frame does include Memorial
Day has been duly noted.) For now will stay with with 30-40 POPS
for this part of the forecast...as we wait and see how the later
runs resolve things. 41

.MARINE...
Elevated northerly winds will gradually weaken throughout the
morning. A Small Craft Advisory is in effect until 5 AM, and small
craft should exercise caution until 10 AM.  Onshore winds will
return early Thursday and quickly strengthen during the day as the
gradient tightens.Elevated winds and seas can be expected from the
end of the week on through the upcoming Memorial Day weekend.
Caution flags will probably be needed, and advisories will be
possible.  11
