DISCUSSION

Issued at 1157 AM CST Fri Feb 27 2026

While the cold front has pushed off the coast, this afternoon is still expected to be pretty warm, possibly warmer than yesterday in a few spots due to clear skies and drier conditions. Afternoon RH is anticipated to drop to around 20-40% for most inland areas, though some deeper moisture should linger over the coast where RH remains around 40-70%). Still not dry/windy enough to prompt any significant fire wx concerns, but enough to be worthy of a mention. Onshore flow returns late this afternoon, ushering in a warming trend through the weekend as ridging builds aloft. Expect highs in the 70s/80s with lows in the 50s/lower 60s. With deep moisture near the coast and onshore flow quickly resuming, we'll still need to be mindful of fog over the weekend during the nighttime. For tonight into Saturday, the risk of fog is generally greater south of the I-10 corridor, especially to the southwest where deeper moisture lingers.

Still expecting a few shortwaves & disturbances pass to the north of our area next week. First of these occurs on Monday, where a cold front attempts to scoot its way into SE Texas. Deterministic GFS has backed off and now keeps that frontal boundary further north, no longer bringing it through SE Texas. The next possible front would be around Wednesday/Thursday with the NBM introducing PoPs around this time from the deeper moisture and better lift in the vicinity of this front. Still, the deterministic GFS has the front stalling just north of our area, and the LREF ensemble members show incredibly strong agreement towards a persistent southerly winds at KCLL through the end of the work week. Perhaps we will see some showers, be presently it doesn't seem like well get a robust cold front anytime soon. Cloud cover may help shave off some of the heat, but overall it'll be warm throughout next week with highs still in the 70s/mid 80s. Overnight lows should rise into the 60s.

AVIATION

(12Z TAF Issuance) Issued at 522 AM CST Fri Feb 27 2026

A mix of LIFR to MVFR conditions currently for most TAF sites due to lower cigs and reduced vis due to patchy to dense fog. Conditions will improve after 15Z with VFR conditions expected for the rest of the day. Winds will be NE to ENE at 5-10 KTS today, then light and VRB after 00Z. There is a chance for areas of patchy to dense fog again late tonight into Sat morning, in particular for areas near and south of I-10.

Cotto

MARINE

Issued at 1157 AM CST Fri Feb 27 2026

Pockets of sea fog linger across the coastal waters this afternoon. Most pockets should clear later today. Drier air filling in from the north may help, though with easterly to southeasterly winds anticipated to quickly return, deeper moisture should linger near the coast with dewpoints just barely at water temperatures. This may result in another night of inland fog spillover & sea fog. Extent and coverage should decrease as waters warm. Otherwise, light winds and low seas will continue through early next week. Winds and seas may increase near the caution flag threshold at times around the middle of next week.
