DISCUSSION

Issued at 1258 AM CDT Thu Oct 15 2026

One more day of above normal temperatures and low chances of an isolated shower til things cool down as the much awaited cold front passes through.

Later this evening and overnight, coastal troffiness across the western Gulf will probably increase in coverage near the coast and offshore. Further inland, after midnight, we'll likely see a thin area of scattered shower & isolated tstm activity develop along the low level convergent zone with the incoming front. Rain totals should be negligible for the most part.

This front is fairly strong for this time of year, supported by a southward push of a 1040mb high tracking through the cntl CONUS. Guidance continues to trend faster and colder...and as such I've made the associated adjustments to the forecast Fri-Sun. Wind Advisories will likely be required at some point as breezy-windy conditions are expected in the wake of the front.

A gradual warming/modifying trend begins early next week as the ridging tracks off to the east...but just to more seasonable levels and not to the warm conditions we're currently experiencing. 47

AVIATION

(12Z TAF Issuance) Issued at 608 AM CDT Thu Oct 15 2026

Southeast flow and isolated showers are expected again today. Like yesterday, afternoon and early evening winds could become occasionally gusty over 15 knots. A strong cold front is expected to push through the region late tonight into Friday morning. A broken line of SHRA is possible along the front, w/ the best chance of SHRA occurring at CLL and UTS. Strong northern winds are expected in the front's wake Friday morning and afternoon, with potential for gusts over 30 knots.

MARINE

Issued at 1258 AM CDT Thu Oct 15 2026

Moderate onshore winds and 3 to 5 foot seas will prevail through tonight. Rain chances will increase, moreso in the Gulf waters, later tonight in advance of a cold front forecast to push into the waters early Friday morning. Look for a wind shift to the north in the early morning hours, followed by an increase of 20-30 knot north winds during the day, and further increasing to close to gale conditions and much higher seas by Friday evening. A Gale Watch is in effect beginning at 1pm Friday. Details in regards to the specific timing and wind strength is somewhat uncertain, but mariners should note that trends have have been for a faster, stronger front. This Watch and possible warnings may need to be adjusted back to Friday morning, especially Freeport westward, should these trends continue. Winds and seas should begin to slowly subside late Saturday into Sunday, but still remain somewhat elevated. 47

FIRE WEATHER

Issued at 1258 AM CDT Thu Oct 15 2026

North winds 15-30 mph with higher gusts are probable Friday into Saturday in the wake of the passing cold front. Though breezy to windy conditions are likely, RH values appear to be above Red Flag Warning criteria. That said, caution is strongly advised with outdoor burning. 47
