KEY MESSAGES

- Cold frontal passage tonight brings more seasonable conditions to the region this weekend.

- Look for a gradual warming/moistening trend early next week.

- Some low rain chances return to the forecast during the second part of the week.

DISCUSSION

Issued at 1212 AM CDT Fri Mar 27 2026

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
