Area Forecast Discussion National Weather Service Corpus Christi TX 501am CST Thu Nov 14 2019 Short Term - Today Through Friday An upper level low over eastern Mexico will open up as it moves across South Texas today. Expect scattered showers to continue through the afternoon before drier air moves in this evening. Overnight Probability of Precipitation will be limited to the islands and coastal waters. Temperatures will be about 10 degrees warmer than yesterday, in the low to mid 50s. A weak cold front will move through this afternoon shifting winds to the north. As the trough moves off to the east, upper level ridging and surface high pressure will build in on Friday. This will help temperatures to continue to warm to the the low 60s for Friday afternoon. Tide levels have been about 0.8 feet above expected. This may lead to tide levels just above 2 feet MSL as P-ETSS/ETSS shows. A Coastal Flood Advisory is in effect from 4pm to 10pm tonight. LONG TERM (Friday Night through Wednesday Night)... In summary, a gradual warming trend can be expected through the weekend and into the middle of next week as the cold Canadian airmass dissipates. A couple of weak systems will bring a slight chance for precipitation Sunday/Sunday Night and again Wednesday/Wednesday Night. Period begins Friday Night with cool surface high pressure settled into South Texas with light NE winds. This will be the last day with 30 degree temperatures for a while. Weak return flow develops on Saturday as next trough moves into the Central Rockies and low pressure develops in the Texas Panhandle. Temperatures will moderate Saturday into the mid to upper 60s with light southeast winds. Mid/Upper level trough and associated cool front will swing through the state on Sunday and off the coast Sunday Night. Isolated showers will be possible ahead of this system along the coast and over the gulf waters. Trended closer to the faster/stronger ECMWF (European Centre for Medium-Range Weather Forecasts) for timing/winds. Mid/upper level ridge then builds over the state Monday/Tuesday resulting in a warm up with max temperatures in the 70s to near 80 degrees. Another disturbance approaches South Texas on Wednesday within the subtropical flow aloft. Expect decent return flow given deepening low in the Texas Panhandle. A few showers will be possible Wednesday aftn/evening within the moist advection pattern aided by the disturbance aloft. Expect highs Wednesday in the upper 70s to lower 80s. Will have to monitor for patchy sea fog if dewpoints climb much above sea surface temperatures.
