| Area Forecast Discussion National Weather Service Corpus Christi TX 602am CDT Sunday Mar 26 2023 Long Term (Monday night through next Saturday) Issued at 358am CDT Sunday Mar 26 2023 Key Message: - Cooler temperatures and a high chance for measurable precipitation are forecast on Tuesday and Wednesday as a cold front meanders across South Texas A cold front will slowly progress southward through the CWA (County Warning Area) on Tuesday. This front will provide forcing for scattered to numerous showers and thunderstorms. The front is expected to undergo frontolysis on Wednesday, but isentropic ascent will be increasing across South Texas. This will support a 20-40 percent chance of showers continuing through Wednesday. PWAT (Precipitable Water) greater than 1.5" and warm cloud layer depth will contribute to efficient rainfall production. This will result in a high probability for the entire CWA to have at least measurable precipitation between Tuesday morning and Thursday morning. There is a 20-30 percent chance for precipitation greater than 1" with the highest likelihood across southwestern portions of the CWA which are currently experiencing severe to extreme drought per the US Drought Monitor. The cloud cover and coverage of precipitation will result in cooler temperatures with a high probability (70%-80%) that highs will not reach 80 on Tuesday and Wednesday. These cooler temperatures will be short lived with ensemble guidance indicating that 500 hPa heigheights will rise over the Southern Plains in response to a trough digging into the southwest CONUS on Thursday and Friday. This will contribute to temperatures returning to the upper 80s/low 90s during the later half of the week. There is a 50% chance that above normal temperatures will continue through the first week of April. Marine Issued at 358am CDT Sunday Mar 26 2023 Light and variable winds today will become southeasterly tonight and shift to the northeast by Monday. Another round of patchy to areas of fog will is expected to develop tonight, with the possibility of dense fog developing across the bays and nearshore waters. Isolated showers with a thunderstorm or two will be possible Monday afternoon. A cold front is forecast to move slowly through the coastal waters Tuesday and Wednesday. Winds will become northeast and increase to around 20 knots in the wake of the front with seas building to 5-7 feet. There is a high chance that Small Craft Advisories will be needed Tuesday into Wednesday. Onshore winds are expected to return by Wednesday night and will remain around 15-20 knots through Friday.
