More of the same during the day today, but we`ll see a cold front
pass across the region this evening and overnight. Cannot totally
rule out a sprinkle or two with its passage, but chances and
significance are not really worth mentioning. We should see a
considerable amount of cloudiness linger behind the shallow
surface front Saturday and into parts of Sunday and have lowered
high temperatures a bit to take this into account. More or less,
it should feel closer to seasonable norms this time of year.

High pressure behind the front moves far enough to our east on
Sunday to allow SE winds from the Gulf to resume. This will bring a
gradual increase in temps/RH during the early and midweek period.
Heading into Wed-Thurs, the dominate mid-upper ridging that`s been
in place will have weakened and moved off to the east and leaving
us in a quasi-zonal flow aloft locally. A weak trof should be
pushing across the Plains and Midwest/Tennessee Valley. Forcing
doesn`t appear to be overly impressive here, but by that time we
should see some 1.6-1.7" PW`s pooling south of its tail
end...hopefully allowing some of us the opportunity to see the
return of some isolated-scattered rain chances during the second
part of the work week. 47

.AVIATION...
(00Z TAF Issuance)
Issued at 640 PM CDT Thu Mar 26 2026

VFR heading into the overnight hours with south winds losing their
gustiness after sunset. Slightly drier air is in place compared to
previous nights...so while we still do anticipate some stratus to
return overnight, thinking is that it might be a bit more
scattered in nature versus previous nights. Have included some
prevailing MVFR conditions for the terminals north and west of the
metro area around 9z. Should be noted some fcst soundings want to
take CLL down to about 600ft at times. Otherwise, VFR areawide by
mid morning Friday. Winds should be lighter out of the south, but
have included a windshift to the NNE for CLL/UTS terminals during
the late afternoon with the arrival of a weak shallow cold front
that`ll pass through the remainder of SE TX Friday night.  47

.MARINE...
Issued at 1212 AM CDT Fri Mar 27 2026

Light to moderate south to southeast winds and low seas will prevail
through late Friday evening. A cold front is expected to push into
the waters between 2-5am Saturday with steadily increasing northeast
winds into the mid morning hours along with building seas. Would
anticipate some 20-25kt winds in the waters east of Freeport, and
just slightly less to the west. Wouldn`t be surprised to see a
few 30kt gusts as some of the hires guidance suggests in the Gulf
waters near/south of Galveston. A Small Craft Advisory will likely
be required. Improving conditions are expected later Saturday
afternoon and night as winds and seas diminish. Southeast winds
resume Sunday and should prevail for most of next week. 47
