000 FXUS64 KHGX 032332 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 532 PM CST Sun Jan 3 2021 .AVIATION [00Z TAF Issuance]... Clear skies and southerly winds around 10 knots continue to prevail at all area airports. Winds will become light and variable as we go into the overnight hours as the pressure gradient from the high pressure east of us goes away. Some forecast models are still hinting at a window for fog in the early morning hours on Monday from 11z-16z. Dew points are higher than yesterday thanks to today`s onshore flow, but still not too confident on there being enough moisture for fog to be a significant issue. For now, BR has been added for all area airports during this time frame with the typical spots for fog getting MVFR visibilities thrown in as well. If fog does develop, it will dissipate by late Monday morning and conditions will return back to VFR for the rest of the day. Monday morning is also when southwesterly winds will kick in around 5 knots for inland areas and around 10 knots along the coast. Looking ahead, winds will become light and variable once again on Monday evening. Batiste && .PREV DISCUSSION /Issued 344 PM CST Sun Jan 3 2021/... .DISCUSSION... Relatively quiet weather remains the expectation this week, with the most impactful weather feature being a midweek cold front that will put a halt to an early week warming trend and bring in a chance for showers and an isolated thunderstorm. Otherwise, look for temperatures that are generally seasonable (a little warmer than average early in the week, a little cooler than average late in the week). Late night/early morning fog should become more of a feature over the next couple of nights as humidity increases ahead of that midweek front. .SHORT TERM [Through Monday Night]... The satellite is again quite clear, with maybe a stray scrap of cirrus marring a completely blue sky. With the full sun and relatively dry air, temperatures have drifted a little above seasonal averages, into the middle to upper 60s across the area. Winds today are south-southwesterly as high pressure moves off to the east, which is helping to usher in some more humidity, though it`s still relatively dry - particularly inland - as we are still moderating a drier airmass. Along with the high moving off, low pressure far to our northwest is deepening. This tighter pressure gradient has made winds today a little gusty as well. Tonight, we`ll see that low and perhaps even a very weak front make its way to the area, while another high slides in behind it. This means that while we can probably expect light winds overnight (and perhaps some patchy fog if we have enough low level moisture in place), we may see winds turn offshore because of this Monday. Regardless, this will be short-lived as a more substantial low will begin to develop in the lee of the Rockies, establishing onshore - but that`s a matter for the long term... .LONG TERM [Tuesday Through Sunday]... With surface high moving east of the area, onshore winds are set to return by Tues. This along with the steady increase of moisture via the Gulf could also signal the return of some low will also POPs by Tues night/early Weds morning in the form of WAA-type showers along the coast. But, the main rain chances look to be with the approach/ passage of a strong cold front and its associated upper low through the region Weds afternoon and evening. Showers and isolated thunder storms are likely for this time frame, but there are hints that the cap will remain too strong for any significant/strong development. Given the rather progressive nature of this overall pattern of late, all this activity should be moving quickly to the E/NE by late Weds night. Cooler temperatures along with mostly clear/sunny skies will be back over SE TX for the rest of the week. Looking way ahead into next weekend, not a lot of consensus so far with the the next upper level shortwave moving in from the W/NW. ECMWF/Canadian seems to be leaning toward one for Fri night or Sat...ahead of a more organized upper low/trof currently progged for late Sun afternoon/night. .MARINE... Expect light, generally onshore winds today to stay light, but become more offshore tomorrow. Since the winds are light, they are also likely to be somewhat variable. Look for winds to establish themselves as onshore again Tuesday in advance of the next frontal passage in the midweek. Expectations are for this front to cross the waters Wednesday night. Offshore winds and elevated seas will develop in the wake of the front late Wednesday into Thursday with Caution or Advisory conditions likely. .HYDROLOGY... For the moment, the only flood warnings in effect are on the San Bernard River - at East Bernard, Boling, and Sweeny. The East Bernard warning will likely be able to be canceled this evening, as the river is falling and is nearly to flood stage this afternoon. Warnings will be needed at Boling and Sweeny for some time yet. Additionally, we continue to watch Normangee closely. While forecast crests have been slightly lower of late, it is still above flood, and the river is forecast to reach flood stage very late tonight. Will give things one more forecast cycle from the RFC this evening before a final decision will have to be made. Should expectations remain that the river reaches flood stage tonight, a warning will have to be issued by the evening shift. && .PRELIMINARY POINT TEMPS/POPS...
