KEY MESSAGES

Updated at 1149 PM CST Fri Feb 27 2026

- Overnight/early morning fog at times through next week.

- Elevated Fire Weather conditions possible at times into next week, mainly across the Rio Grande Plains.

- Increasing rain chances middle of next week?

DISCUSSION

Issued at 1149 PM CST Fri Feb 27 2026

Morning fog will give way to clear skies by early afternoon. Late night and early morning fog will be possible through early next week, but visibilities may remain above 2SM across the land areas. By mid week, winds may be a tad to strong for fog to develop over the land, but could still develop across the bays and coastal waters. Otherwise, unseasonably warm conditions will continue into next week with temperatures remaining around 10-15 degrees above normal.

Rain chances will remain low to nil through the weekend due to a mid to upper level high pressure system. The high pressure is expected to shift east on Monday through Tuesday. A deepening upper low moving southeastward from the Pacific NW will bring a southwest flow aloft with embedded short waves tracking across the region, which could bring a low to medium (20-40%) chance of rain by the middle of next week when moisture begins to deepen (PWATs increase to 1.2-1.5 inches) and combine with the upper short waves. If we do get rain the latter half of next week, it could bring some relief from the heat, but likely will not make any significant improvement to the reservoirs.

AVIATION

(06Z TAFS) Issued at 1149 PM CST Fri Feb 27 2026

Difficult aviation forecast this period with ongoing fog/stratus advecting across the area. A solid band of LIFR CIGS is pushing westward, currently just past ALI and VCT. Expect this to reach LRD in a few hours, but could mix a bit higher and be more very low IFR. Have kept it LIFR in the TAF though as it is solid 300ft at this point. VIS also difficult with some improvement being noted for sites that saw an early drop to IFR conditions. Winds being a bit elevated are probably the most likely culprit for this improvement, but not sure that it'll hold through the night, so will keep IFR to tempo LIFR noted at eastern sites. VFR conditions return to all sites by mid to late morning. Have indicated an early drop fro CRP again late in the period, but confidence on this is low as it is dependent on a lot of factors for advecting sea fog (wind direction, water temperature and dewpoint), all of which have the potential to come together, but again, not a certainty.

MARINE

Issued at 1149 PM CST Fri Feb 27 2026

Patchy to areas of fog will continue across the bays and nearshore waters through Saturday morning with visibilities generally 1 mile or less for most of the area. A Marine Dense Fog Advisory is in effect until Noon Saturday. Areas of fog remain possible at times through the period. A light to gentle (BF 2-3) onshore breeze will continue through Saturday morning, then strengthen to a moderate (BF 4) breeze through Saturday afternoon and continue into early next week. Onshore winds are expected to increase to a fresh (BF 5) breeze by mid week. Rain chances will be low (5-20%) through Tuesday, increasing to a 20-30% by mid week.

FIRE WEATHER

Issued at 1149 PM CST Fri Feb 27 2026

Onshore flow will increase the humidity across South Texas. However, fuels remain cured, thus elevated fire weather conditions are possible at times through the weekend into next week, mainly across the Rio Grande Plains where minimum RH values will be in the upper 20s to lower 30s. Winds are expected to remain below thresholds through early next week. However, winds may strengthen to critical levels by the middle of next week, but so do the minimum relative humidity values.
