Area Forecast Discussion National Weather Service Corpus Christi TX 256pm CST Monday Feb 17 2025 ...New SHORT TERM, LONG TER Marine .SHORT TERM... (Tonight through Wednesday) Issued at 216pm CST Monday Feb 17 2025 Key Messages: - Strong cold front expected Tuesday night into Wednesday morning. - Wind chills below freezing across the northern counties Wednesday morning. - Low (~20%) chance of showers over the Victoria Crossroads along the cold front Southerly flow tonight will lead to warmer temperatures and increasing moisture tonight and Tuesday. Highs Tuesday will range from the mid-70s to low-80s ahead of a strong cold front. Guidance is still a little nebulous on the frontal arrival, with the GFS (Global Forecast System) a bit faster than the NAM, and the ECMWF (European Centre for Medium-Range Weather Forecasts) even faster than the GFS. Regardless, all models indicate the front will be through (or nearly through) the area by Wednesday morning. There is a low chance of showers ahead of and along the front. A rumble of thunder or two will also be possible, but most of the favorable upper level dynamics will remain to the north, so confidence in any thunder is very low. Behind the front, chances for showers will diminish Wednesday as cold, dry air streams into the area. Windy conditions are expected, with the potential for a Wind Advisory Wednesday morning along the barrier islands. Temperatures will dip into the mid-30s to mid-40s Tuesday night and Wednesday morning with wind chills dipping as low as 25 for a few hours across the northeast. Highs will hover around 50 Wednesday. Long Term (Wednesday night through next Sunday) Issued at 216pm CST Monday Feb 17 2025 Key Messages: - A Cold Weather Advisory is likely Thursday morning with wind chill values in the teens and low 20s. The coldest temperature over the area will be Thursday, with early morning lows ranging in the mid 20s to mid 30s along the coast. A coastal trough will develop Sunday, returning onshore flow and increasing temperatures, with highs in the 70s and 80s Sunday and Monday. A moderate (25-55%) chance of rain is expected Friday through Saturday as moisture returns to the area as a surface low over the Gulf approaches the area. These chances will diminish from west to east Saturday afternoon through Sunday, leaving us dry early next week. Marine Issued at 216pm CST Monday Feb 17 2025 Weak to moderate southeasterly flow will continue through Tuesday night, when winds will turn to the north and increase in response to a strong cold front. A Gale Watch will be in effect Tuesday night though Wednesday as strong to occasionally very strong winds develop. Moderate to strong winds will continue through the end of the work week with a Small Craft Advisory likely. There is a low to medium (20-60%) chance of showers over the waters Tuesday through the end of the week. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX...None.
