DISCUSSION

Issued at 1235 AM CST Thu Feb 19 2026

Surface low pressure area over SE Kansas early this afternoon will track northeastward. The tail end of it's associated weak surface front will sag into northern parts of SE TX overnight then stall as it loses support for a continued southward push. Other than a slight decrease in RH's and light N/NE wind shift, overall sensible wx will be negligible. Closer to the coast, sea fog is expected to expand in coverage this evening and track toward the I-10 & metro area. Fog could be dense at times.

Friday, the stalled front will eventually wash out. Can't totally rule out an isolated shower or two in the vicinity or to it's south, but nothing of significance.

Saturday we'll see our next front push across the region during the day. Available moisture will generally be confined below about H85 capping, and dry air further up, so doubt will see much, if any, rain with this fropa. Cooler and more seasonable wx will prevail Sunday into much of next week with a mostly dry nw flow aloft prevailing. 47

AVIATION

(18Z TAF Issuance) Issued at 1235 PM CST Thu Feb 19 2026

With the exception of coastal areas where IFR conditions will be present, VFR conditions will prevail across the rest of the area today. Deteriorating flying conditions are anticipated for the overnight hours as sea fog expands and moves inland. Periods of dense fog, and potentially LIFR ceilings will fill in south-north into the metro area. Further north, visibilities will probably be more in the 2-5 mile range along with some MVFR ceilings. Just modest improvement through the mid-late morning hours Fri...eventually trending back to VFR in the early afternoon. 47

MARINE

Issued at 1235 AM CST Thu Feb 19 2026

Sea fog will be the primary concern through Saturday morning. The best chance of fog will be during the evening, overnight, and morning hours. However, patchy fog could linger near the coast and over the nearshore Gulf through the afternoon hours. A cold front will push offshore on Saturday. Strong north winds and building seas are expected in its wake by Saturday evening. Gusts close to gale and 7-10ft seas look to be a possibility in the Gulf waters. Small Craft Advisories are likely by Saturday night and Sunday. 47
