000 FXUS64 KHGX 050505 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1105 PM CST Fri Dec 4 2020 .AVIATION [06Z TAF Issuance]... Confidence high in the broad strokes of the forecast - clear and light winds overnight, winds gradually becoming northerly while clouds increase through the day from the SW, cloud base decreasing as the column moistens. Later in the day and overnight, rain chances increase from the SW as well, with MVFR and potentially IFR CIGs developing as well. What will need to be refined through the day will be precise timing on these changes. && .PREV DISCUSSION /Issued 550 PM CST Fri Dec 4 2020/... .SHORT TERM [Tonight Through Saturday Night]... High pressure over the area will move east making way for an upper level low in western TX to migrate northeast and eventually north of the CWA Sunday morning. Cloud cover will progressively increase tonight as moist/southwesterly flow in the mid levels continue. Surface trof along the coast will set up tomorrow morning and some deepening will allow for some lift but the northerly surface flow will remain fairly dry. PWs will peak at about 1" over CWA tomorrow night giving the higher chances of accumulation, with the upward trend will start tomorrow morning. So sadly, this adds up to most of the weekend is not looking bad, but certainly overcast and areas of drizzle with peak chances Sunday morning. I-10 to Huntsville/College Station area may see trace amounts of precipitation tomorrow, with higher chances in the afternoon. Areas south of I-10, mainly directly along the coast, could see a measurable amount of precipitation with higher chances in the afternoon. Cloud coverage will keep temperatures mild tonight again with lows close to freezing in the northern counties and low to mid 40s along the coast. Tomorrow, highs will reach the mid 50s across the area low stratus tomorrow night will keep most of the counties in the low to mid 40s. Northwestern counties could still reach the mid 30s as early morning skies clearing could still allow for fast and short lived dip in temperatures. 35 .LONG TERM [Sunday Through Friday]... Rainfall will taper off by Sunday morning, with progressively clearer skies taking hold through the day. As upper ridging once again takes hold and a broad area of surface high pressure becomes established over the south-central CONUS, dry and cool weather should remain the story across SE Texas through the middle of next week. During this time, we`ll continue to experience below normal temperatures with highs reaching the low to mid 60s through Tuesday. Clearer skies should allow for relatively uninhibited radiative cooling, and as a result should continue to see lows near freezing across the northern zones and in the lower 40s across the Houston metro area. Our next period of active weather looks to arrive by the end of next week, though there`s still disagreement across model solutions that brings quite a bit of uncertainty to the situation. As the aforementioned area of high pressure shifts eastward, daytime high temperatures will begin to recover to more seasonable values as the offshore flow pattern erodes. Meanwhile, a developing upper low/longwave trough aloft will begin to push eastward along with an associated deepening surface cyclone that will bring our next cold frontal passage as it moves through the Central Plains. The question for now is exactly how quickly this will occur. As has been the case of late, the GFS favors a more progressive solution and places the upper trough over central TX by Friday morning, while the surface cold front reaches the coast by the evening. The EC, on the other hand, does not depict the approach of the boundary until late Saturday/early Sunday. With the recent poor track record of progressive GFS solutions, have opted to side with the EC for the time being and carry only 10-25% PoPs on Days 7-8. Cady .MARINE... Much quieter wind forecast for the marine area this afternoon through Wednesday. High pressure over Texas will lead to offshore flow through Tuesday. The only short term issue will the s/w over Mexico this afternoon tracking into the Hill Country late Saturday leading to an enhancement of the winds over the UTCW with a coastal trough and an increasing chance for stratiform rain spread in from the southwest Saturday 7-10 am and peaking Sunday late morning and afternoon with bands of embedded heavier showers. 45 && .PRELIMINARY POINT TEMPS/POPS...
