.PREV DISCUSSION /Issued 333 PM CST Fri Dec 25 2020/...





.LONG TERM [Sunday through Friday]...

High pressure will be moving off to the east over the weekend, and
this will allow for south winds to return to the area and help to
warm us back up as moisture levels gradually rise and we get some
increase in cloud cover. By Sunday, almost everyone can expect to
warm up into the 70s. Heading on into Sunday night and Monday, we
can expect to have a weak cold front sag into our northern county
area that should bring a slight cool down up there with upper 60s
for highs instead of 70s. The next developing storm system to our
west will help to edge this front back northward Monday night and
Tuesday. Strengthening southeast winds and rising moisture levels
will then help to set the stage for our next best rain chances as
the storm system`s cold front moves eastward across our area Tues
night through Wednesday morning. Look for the area to rapidly dry
out behind the front and also cool back down with highs Wednesday
mostly in the 60s and lows Wednesday night back into the 30s/40s.
The last day of 2020 and the first day of 2021 (Thursday & Friday)
will be cool (lows in the 30s/40s and highs generally in the 50s/
60s) and also dry as high pressure builds in behind the front. 42


.MARINE...

Light winds becoming southerly and seas of 1-2 FT expected
tonight through Saturday. Onshore flow will increase Sunday and
may reach Caution criteria for a few hours in the morning and then
subside in the afternoon. Winds strengthen Monday into Tuesday as
the pressure gradient tightens, and may require the issuance of
SCEC/SCAs. Chance of rain increases Tuesday as a weak cold front
moves into SE Texas Monday and stalls just shy of reaching the
local waters. Another, more robust but quick moving, cold front
will move across the waters Wednesday, increasing shower and
thunderstorm development across the bays and Gulf waters through
Wednesday night. Marine conditions improve overnight Thursday
night into Friday.

Tides: Water levels will continue to rise tonight and are expected
to remain above low water advisory threshold through the next few
days. 24
