Area Forecast Discussion National Weather Service Corpus Christi TX 1052 PM CST Tue Nov 30 2021 .AVIATION /06Z TAFs/... VFR conditions are currently in place across the region. MVFR ceilings and visibilities are expected to develop over the next few hours as low level stratus and patchy fog sets in. Fog may be dense at times with periods of IFR/LIFR visibilities occurring closer to sunrise. VFR conditions will return by mid morning and persist through the end of the TAF cycle. South-southeasterly winds will continue through the period. && PREV DISCUSSION... /Issued 336 PM CST Tue Nov 30 2021/ SHORT TERM (Tonight through Wednesday Night)... A weak mid level ridge axis along the Rio Grande to southwest Texas tonight and Wednesday will translate to the east into central Texas by 12Z Thursday. Will see periods of high clouds move across the region during the short term with temperatures remaining slight above normal. Surface high pressure ridge will remain along the coast tonight into Wednesday morning. Winds will become light tonight and provide a favorable environment for radiational fog over the inland coastal plains into the eastern Brush Country. One thing that may deter fog formation, models show southerly flow at 925 mbs increasing to around 20 knots. Models bring a moist layer/clouds into the Coastal Bend but NAM may be a bit overdone with the amount of moisture. Will continue to forecast areas of fog developing over the inland coastal plains, but will let later shifts determine if a Dense Fog Advisory is needed. The surface high pressure ridge will be inland Wednesday night, so there may be a better chance for dense fog over the coastal counties as the NAM/CONSShort models indicate. LONG TERM (Thursday through Tuesday)... At 250mb, ridging will dominate Thursday before a weak trough followed by quasi-zonal flow persists over South Texas Friday through Sunday, with a jet streak just north providing some areas of diffluence. Meanwhile at the mid-levels, a cutoff low just west of Baja California in the Pacific will send a series of shortwave disturbances through Friday. Moisture will increase to around 1.5" PWATs by Friday and with a mid-level disturbance providing lift aloft, as well as isentropic lift at the surface indicated at 300K, isolated to scattered showers and thunderstorms will be possible with CAPE values up to 1200 J/kg and CINH minimal per GFS. The NAM/ECMWF/CMC also show isolated coverage during the same period but lighter QPF. Persistent onshore flow, a new moon phase, and a slight increase in winds, could lead to minor coastal flooding as water levels reach 2.0 ft MSL according to P-ETSS. As the mid-level disturbances shifts northeastward Friday night, so will any precipitation. Leading to ridging and drier conditions Friday night through Sunday morning. Heading into Sunday afternoon and onwards, model discrepancies become extremely apparent, especially in regards to the synoptic pattern. The ECMWF/CMC keeps that aforementioned cutoff low southwest of Baja California through Tuesday, putting South Texas in a mostly ridging pattern with bands of vorticity stretching west to east across over the northern portion of the CWA or Hill Country. However, the GFS is drastically different, having the cutoff low get shoved eastward from a stronger upstream trough, focusing right over South Texas Tuesday. This feature over South Texas, along with PWATs hinted over 1.75" (>99th percentile) shows over 2.0" QPF through the day across the region. Since this is the first maybe second run of the GFS that shows this, there really hasn't been any consistency and confidence is very low to include any mention while the ECMWF/CMC agree and have been more persistent. We'll have to keep an eye on trends in future runs. Model guidance do agree on sending a cold front down late Tuesday night into Monday morning that warrants at least slight chances of showers and thunderstorms as it weakens near or over the area. Following Monday, have left silent PoPs due to the high uncertainty. Upper 70s to mid 80s for our highs are expected Thursday through Saturday as partly cloudy skies stay intact. Increasing cloud cover early next week from the mid-levels will cool highs down into the 70s. Lows in the upper 50s to mid 60s through Saturday night, may decrease a few degrees to range from the mid 50s to lower 60s Sunday night and Monday night if offshore flow develops. MARINE... Weak onshore flow will continue tonight into early Wednesday morning. Winds will become light northeast by Wednesday afternoon as the high pressure ridge settles into the coastal waters. Winds will become light east Wednesday night. Generally weak onshore flow and increasing moisture is expected through Saturday, slightly strengthening to weak to moderate Saturday night. A cold front may pass over the waters Monday, causing winds to shift northeasterly. Isolated showers and thunderstorms will be possible Friday into early next week as moisture remains greater than normal and disturbances aloft enhance lift support. && .PRELIMINARY POINT TEMPS/POPS...
