Area Forecast Discussion National Weather Service Corpus Christi TX 626pm CDT Sat Mar 28 2020 by National Weather Service Austin/San Antonio TX/ SHORT TERM... The cold front pushed across the western portions of the CWA this morning and is currently sweeping through the Coastal Bend and the Victoria Crossroads. This morning's sounding showed a weaker cap with PWAT (Precipitable Water) values of 1.6 inches with models suggesting that PWAT values can approach 2 inches across portions of the Coastal Bend and the Victoria Crossroads. The weakness in the cap will allow showers and isolated thunderstorms to develop along the boundary as the front pushes through. Cooler and drier air will settle in behind the front as the winds shift out of the north. The cold front is expected to stall in the Gulf of Mexico on Sunday. LONG TERM... Chances for rain and an isolated thunderstorm will continue through Monday and Monday night as a warm front moves north into the area, returning moisture and onshore flow. PWATs (Precipitable Waters) will reach near 2" ahead of the next weak cold front Monday night/Tuesday morning but even with this moisture, convection will be limited as strong capping is likely to remain in place. Temperatures will drop a few degrees with drier air filtering in from the north. Surface high pressure will build in behind the front Tuesday, then shift east Wednesday which will result in onshore flow and moisture return. A series of shortwaves will move through during the week, so rain chances will not go away completely, though we expect only a sprinkle or two. Another front could move through the area Friday through Saturday, but will defer any major decisions on this until the models come into better agreement. For now, have left slight chance of Probability of Precipitation in the forecast. Marine Discussion A weak cold front is pushing through the area which will generate showers and the possibility of isolated thunderstorm. After the passage of the front the winds will shift to a weak to moderate offshore flow. The cold front is expected to stall over the Gulf of Mexico on Sunday with a weak to moderate onshore flow returning by Sunday night. Onshore flow on Monday will serve to increase moisture. Periods of SCEC conditions (Small Craft Should Exercise Caution) will be possible Monday and some isolated thunderstorms are possible. A weak cold front will move across the waters late Monday night/Tuesday morning leading to offshore flow and isolated showers and thunderstorms. Rain chances will end Tuesday afternoon, with only an isolated shower or two possible over the waters through the end of the week. Onshore flow will return Wednesday as high pressure shifts east. Periods of SCEC conditions are likely for the end of the week. Fire Weather A cold front swept across the area today and generated some light rain showers across most of the forecast area. Drier and cooler air will filter into the area as high pressure settles in behind the front. The Red Flag Warning for Webb County is slated to expire at 23z today. At this time conditions do not look favorable to extend the warning, thus the warning will expire at 23z. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
