256 FXUS64 KCRP 290651 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 151 AM CDT Mon Jun 29 2026 ...New DISCUSSION, AVIATION, MARINE, FIRE WEATHER... .KEY MESSAGES... Updated at 138 AM CDT Mon Jun 29 2026 - Moderate risk of heat-related impacts through this week, afternoon heat indices of 100-108 - Low rain chances return Thursday, mainly along seabreeze over the Coastal Plains - Saharan dust may cause hazy conditions at times today and Monday - Hazardous marine conditions through Monday afternoon, with winds at least gusting frequently to 20 knots or greater && .DISCUSSION... Issued at 138 AM CDT Mon Jun 29 2026 High pressure will remain anchored over the east-central CONUS through the upcoming week, with South Texas remaining under its influence. Rain-free conditions with max temperatures in the 90s along with heat indices of 100-108 are expected through Wednesday. The ridge will begin to weaken late this week allowing shortwaves to ride along the southern periphery and moisture to increase above normal (PWAT values between 1.7-2.00". This will result in low shower and thunderstorm chances (10-20%), mainly along the seabreeze, over the Coastal Plains Thursday and Friday. Looking into next week, guidance is still in good agreement on a mid to upper level trough digging in from Canada into the Central Plains this weekend, but then differs through early next week so it is too soon to tell if we will have any significant rain chances moving in. Dust aerosol optical thickness forecast from NASA/GMAO shows noticeably higher dust concentration moving over South Texas today. This may cause hazy conditions occasionally, reduce air quality, and heighten allergies and respiratory issues. && .AVIATION...

ERC values in the 25-49th percentile and fuels with normal to above normal dryness will limit fire weather danger for the upcoming week. && .PRELIMINARY POINT TEMPS/POPS...
