Small Craft Advisories are in effect for the bays and coastal waters Thursday morning through Thursday afternoon. A Gale Watch is then in effect Thursday evening/night. Rain chances will come to an end Thursday night. Strong to moderate northeast flow Friday. Wind will become weak to moderate onshore by Saturday, as surface high pressure moves east. Weak to moderate onshore flow will persist Saturday night and Sunday as an upper level disturbance approaches the Southern Plains.

Area Forecast Discussion ...UPDATED National Weather Service Corpus Christi TX 609pm CST Wednesday Feb 19 2020 Short Term - Tonight Through Thursday Night Overall...damp, cold and cloudy conditions will persist through the short-term period. Overrunning pattern that allowed for patchy light rain and drizzle to develop across the region today will continue overnight with periods of reduced visibility also developing. By Thursday morning, reinforcing high pressure will push a secondary/deeper front through the area weakening the overrunning pattern and bringing chances for isolated to scattered showers. However, rainfall should remain fairly minimal during this timeframe with rainfall amounts totaling to a quarter of an inch or less. This surge in high pressure will lead to breezy/windy conditions to develop across the area Thursday morning along with strong CAA. Temperatures tonight will fall into the upper 40s to lower 50s, with high temperatures on Thursday struggling to get out of the 50s. Precipitation is forecast to come to an end from west to east by Thursday evening across inland locations. Minor coastal flooding continues to be possible along area beaches Thursday evening into Thursday night with both ETSS and ESTOFS indicating tide levels exceeding the 2.0 feet MSL threshold. Long Term - Friday through Wednesday The GFS/ECMWF (European Centre for Medium-Range Weather Forecasts) deterministic NWP (Numerical Weather Prediction) model runs are generally consistent with a progressive upper pattern during the period, with the CWA under/east of an upper ridge axis Friday/Saturday, followed by increasing synoptic scale ascent over the CWA Saturday night/Sunday associated with an upper disturbance predicted to move across the SRN Plains/TX. Expect with the combination of the upper forcing/moisture to contribute to isolated/scattered showers over the ERN CWA Sunday/Monday. Drier conditions Monday night through the remainder of the period. Unclear whether the cumulative effect of Ekman forcing will contribute to coastal flooding Friday. Marine Discussion Isolated to scattered showers will remain possible overnight and again on Thursday. A strong secondary front will push through the region Thursday morning with strong to very strong winds developing and continuing through Thursday night. Small Craft Advisories are in effect for the bays and coastal waters Thursday morning through Thursday afternoon. A Gale Watch is then in effect Thursday evening/night. Rain chances will come to an end Thursday night. Strong/moderate northeast flow Friday. Onshore flow/increasing moisture Saturday. The combination of an upper disturbance and greater moisture will contribute to isolated/scattered showers Sunday/Monday. Drier conditions/weak to moderate offshore flow Monday night/Tuesday.
