196 FXUS64 KCRP 021920 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 220 PM CDT Fri Oct 2 2026 ...New DISCUSSION, AVIATION, MARINE, FIRE WEATHER... .KEY MESSAGES... Issued at 150 PM CDT Fri Oct 2 2026 - Marginal risk of flash flooding continues through this weekend, slight on Saturday over the southern Coastal Bend - Weak cold front pushes through late tonight into Saturday morning - Medium to high rain chances this weekend, lower Monday, becoming rain-free Tuesday - Monitoring minor coastal flooding through this weekend && .DISCUSSION... Issued at 150 PM CDT Fri Oct 2 2026 A positive vorticity axis earlier over the Coastal Plains will move inland into the Hill Country through this afternoon and tonight; focusing convection / rain chances north of our CWA, leading to a lull in our rain chances. The weak cold front will finally push through late tonight into Saturday morning. A surface low will likely develop south over the western Gulf, but how far south will greatly determine our rain chances through the weekend, lowering my confidence on the future rain coverage. Recent guidance has trended to a farther southward progression of the surface low, decreasing rain chances. Nonetheless, overrunning of showers and thunderstorms along with low-level moisture convergence, will lead to a medium to high chance of showers over South Texas. Greatest chances and coverage is expected over the Coastal Bend through Sunday, due to greater convergence and proximity to the low. The low washes out as we get a second push of northerly winds Monday, lowering PWATs and rain chances. Moisture falls well below normal (PWATs around 1.5") Tuesday through Thursday due to offshore mid-level flow, leading to rain-free conditions. Lastly, due to the persistent northeasterly flow enhancing the Ekman transport mechanism and increasing 7-8 second swell periods, minor coastal flooding is worth monitoring this weekend, especially during high tide at night into the early morning hours. && .AVIATION... (18Z TAFS) Issued at 150 PM CDT Fri Oct 2 2026 Only a few showers over South Texas this afternoon, but we`re seeing cells develop as heating continues. Coverage looks to decrease tonight over much of the Coastal Plains, then focus more over the Rio Grande Plains. A cold front will push through late tonight into Saturday morning, leading to MVFR ceilings across South Texas primarily after 06Z. && .MARINE... Issued at 150 PM CDT Fri Oct 2 2026 Gentle to moderate northeasterly flow will strengthen to fresh to strong Sunday to Tuesday morning, leading to occasional Small Craft Advisory conditions. Moderate to fresh northeasterly flow will return through the latter half of next week. Scattered to numerous showers and thunderstorms will continue through Tuesday, then low rain chances latter half of the week. && .FIRE WEATHER... Issued at 150 PM CDT Fri Oct 2 2026 No significant fire weather concerns are anticipated through next work week. Scattered to numerous showers and storms are expected through the weekend with lower chances continuing into Monday then becoming rain-free starting Tuesday. RH values will remain elevated above 30% each day with highs struggling to reach the 90s. && .PRELIMINARY POINT TEMPS/POPS...
