718 FXUS64 KCRP 101000 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 500 AM CDT Wed Oct 10 2018 .SHORT TERM (Today through Thursday)... The weak cold frontal boundary continues to push offshore, although LAPS analysis shows a weak boundary extending westward across the far southern Coastal Bend which may keep isolated activity over land through the morning hours before the boundary pushes farther south. Much drier conditions are expected for the afternoon as high pressure and drier air move in behind the front, shunting the available moisture farther south. May see a bump in the winds late this morning, especially over the nearshore waters, as a quick surge of high pressure moves in, with a second bump tonight. Moisture is then expected to gradually be drawn northward up through the Rio Grande Valley with slight rain chances for Thursday for the western Brush Country. Temperatures are expected to be on the warm side today under partly cloudy skies. Overnight lows should be cooler in the low to mid 60s across areas from Cotulla to Port Lavaca, and in the upper 60s to low 70s from near Laredo to along the Middle Texas Coast. && .MARINE... Swells and wave heights have increased dramatically yesterday evening across the Middle Texas Coastal waters all in response to Hurricane Michael in the eastern Gulf of Mexico. Small Craft Advisories will continue through this evening as wave heights remain between 5 to 7 feet across the nearshore waters, and 7 to 9 feet across the offshore waters. As for the Coastal Flood Advisory and High Rip Current Risk, have extended these products through Thursday morning as swell periods continue to run high at 10-14 seconds. This combined with astronomical high tides along with a new moon have led to tides running about 1 to 1.5 feet above normal. This will lead to water covering local beaches as well as noticeable water rises in area bays. In addition, the high swell periods will continue to lead to high rip current risks along the gulf facing beaches. The Coastal Flood Advisory and High Rip Current Risk products are currently in effect through Thursday morning, but may need to be extended past Thursday morning. && .LONG TERM (Thursday night through Tuesday)... The ECMWF/GFS/NAM deterministic predict an upper level disturbance to move across the Plains/Midwest Thursday night through Friday night, while a flat E-W oriented upper ridge affects the Gulf of Mexico/CWA. The ECMWF/GFS predict another upper system to enter the NRN Rockies Friday night/Saturday from Canada, then move across the Plains/Midwest Sunday/Monday. The surface reflection/cold front associated with this second system is predicted to move across the CWA Sunday night/Monday. Expect increasing moisture/onshore flow expected over the CWA/MSA Friday/Saturday (ECMWF deterministic PWAT values) to contribute to at least isolated convection. Expect the chance for convection to increase Sunday/Monday owing to the proximity of the front. SCA conditions may occur over the coastal MSA after frontal passage Monday (WaveWatch III output.) Drier conditions anticipated Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
