134 FXUS64 KCRP 281134 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 534 AM CST Sat Feb 28 2026 ...New AVIATION... .KEY MESSAGES... Updated at 528 AM CST Sat Feb 28 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... (12Z TAFS) Issued at 528 AM CST Sat Feb 28 2026 Difficult aviation forecast continues in terms of diurnal fog and stratus. Conditions generally improved through the night with mainly MVFR conditions east and IFR conditions west. Have kept mention of lower VIS potential for a few hours around sunrise this morning starting to see indications of worsening conditions once again as often happens around sunrise. After VFR conditions during the day today, will once again have to consider the potential for lower flight category conditions tonight. Not seeing much different in the pattern for the evening than we saw last night, so we could see a quick development of fog over the water advecting toward the CRP terminal around 00Z. After that, winds just above the surface are expected to be notably stronger than they have been early this morning, giving more of a stratus than fog look. CIGs could once again fall to LIFR levels, especially at eastern sites, but for now not indicating a significant VIS reduction. && .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. && .PRELIMINARY POINT TEMPS/POPS...
