| Area Forecast Discussion National Weather Service Corpus Christi TX 405am CST Sunday Jan 16 2022 Short Term - Today Through Monday Concur with the deterministic output which predicts an upper low moving across the SERN CONUS today, followed by a quasi-zonal pattern over the CONUS Monday. The NAM maintains below normal PWAT values during the period. A gradual warming trend with respect to high temperatures is expected. Near freezing temperatures expected again tonight. Not confident with regard to a Freeze Warning given SREF and HREF freeze probabilities. Long Term - Monday Night through Saturday Fairly quiet beginning to the long term period with a weak shortwave passing by on Monday night, but with very dry air (PWAT (Precipitable Water) < 0.5"), will not have any impact on the region. Temperatures will be gradually increasing into the middle of the work-week with a zonal mid level flow and 850 winds turning back to the southwest ushering in 850mb temps up to 18-19C. High temperatures Tuesday and Wednesday will be back into the lower 80s (west Tues, much of the area Wed). Wednesday night into Thursday we'll see a big change as a cold front moves through with a rather cold airmass behind it. Moisture ahead of the front is still limited, but could see a few showers along the front, and then isentropic lift flow develops to keep rain chances in the forecast through early Friday. Best rain chances are offshore, but have slight chance Probability of Precipitation over the entire area and chance Probability of Precipitation mainly in the Coastal Plains. After morning low temperatures in the 40s for most of the area Thursday, daytime temperatures will be only in the 50s...and probably the lower side of 50s for most of the area. Combine this with the northerly wind and showers/drizzle, and it'll feel a lot like winter out there. Low temperatures Thursday night will drop into the 30s with a few areas approaching freezing...as winds subside. For those of you doing the math...I did mention temperatures approaching freezing and rain chances at the same time. And that equals a difficult forecast. While I'm not adding any frozen precipitation types into the forecast at this time, it is worth mentioning the possibility, mainly north. Right now, the ECMWF (European Centre for Medium-Range Weather Forecasts) is the colder model...but also ends rain chances earlier, so likely would not line up for anything frozen. GFS is warmer, but keeps rain chances longer. GFS profiles currently suggest rain with a significant warm layer to melt anything that is frozen aloft. And then there's the NBM with ptypes indicating the potential for some mixed precipitation. All that in mind, confidence is pretty low in any potential for frozen precipitation but it is definitely something to keep our eyes on as we move through the week. Once we get through the precipitation into Friday, we should mainly end rain chances by the afternoon, though a slight chance will remain near the coast into Saturday with slightly higher chances over the waters. Cold air remains in place Friday and Saturday with highs in the 50s. Low temperatures Friday night would likely approach freezing once again. Marine Strong/very strong north wind and high seas early this morning. Expect improving conditions from west to east today After coordinating with WFOs BRO/HGX, will retain the Gale Warning over the coastal waters until 15z, hoisted a Small Craft Advisory for the nearshore coastal waters 15-18z and offshore coastal waters 15-21z. Anticipate only Small Craft Exercise Caution conditions over the bays this morning. Dry conditions expected during the period. Onshore flow will become moderate on Tuesday as low pressure develops over the southern high plains. Southerly winds could increase to moderate to strong levels over the Gulf waters Tuesday night but decrease to weak to moderate for Wednesday. A cold front will move into the coastal waters late Wednesday night with a strong offshore flow developing behind the front Thursday into Thursday night. Scattered showers will be possible along and behind the front Wednesday night through Thursday night.
