896 FXUS64 KHGX 210140 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 740 PM CST Fri Nov 20 2020 .SHORT TERM [Tonight Through Saturday]... Clouds and fog will be filling in across the area through 2 am. Widespread cloudiness and fog should prevail after 2 am. Expecting that a dense fog advisory will probably be needed at some point after midnight. Showers should be on the increase toward morning over the southeastern coastal waters and then expand toward the coast by late morning. Some very minor tweaks to the current forecast for temperatures this evening and cloud cover. Cleared out the rain chances through 5 am inland. 45 && .AVIATION [00Z TAF Issuance]... What started off as a VFR set of TAFs at 00z needed fixing with LBX down to IFR already but this is likely to bounce around as low level moisture increases tonight and by 06z expecting more widespread stratus formation with IFR/LIFR conditions to take hold. VLIFR visby/cigs are possible after 10z through 15z then rapid improvement should occur with some spotty showers mainly southwest of SGR/LBX...if the 00z short term guidance continues to highlight these areas for precip will likely be needing to add VCSH to the these terminals. 45 && .PREV DISCUSSION /Issued 237 PM CST Fri Nov 20 2020/... .LONG TERM...(Monday through Friday) A parade of fronts is the main weather story for the Thanksgiving week. Upper ridging aloft remains strong while it gradually shifts eastward early next week. Meanwhile, an upper-level disturbance over the southern Plains will attempt to bring the famous front that we have been talking about over the last days. NAM, which usually handles well shallow fronts only suggest a slight drop in dewpoints. The EC also continues to bring this shallow/weak front over our region. Have leaned the forecast towards NBM/NAM/EC, having the front passing through the region Sunday night Monday. Impacts are not expected to be major, but a relied in dewpoints is expected with values mainly in the 50s. East to southeast flow quickly filters in behind the front, brining warm and slightly humid conditions on Monday. Tuesday is progged to be the warmest day of the long-term period with upper ridging to our east and 850 hPa temperatures in the 12-15C range in advance of the next upper-level trough and associated front. Although the stronger lifting remains far north of the CWA, strong return flow and warm air advection will push into the region, increasing moisture and instability. Deterministic models continue in agreement with this trough, bringing rain and thunderstorm chances ahead the front, followed by a strong and drier airmass. Breezy to windy conditions are also expected ahead of the front, higher gusts possible over the waters. Showers and storms gradually weaken/move out of the region later on Wednesday as a surface high pressure builds in. Dry conditions are expected for Thanksgiving with temperatures near to slightly above average. Pattern continues to look unsettled and cooler towards the end of the week, as an upper-level disturbance and associated front track east over the southern Plains. However, uncertainty is high given a broad divergence between global models. 05 .MARINE... Will extend the SCEC for the 20-60 NM waters through this evening as seas remain elevated due to long period swells propagating into the marine zones. At 2 PM, seas remain near 6 feet with a 10 second period. The swells are are also causing some strong rip currents on Gulf facing beaches so will maintain the Rip current statement tonight. An E-NE flow is expected through the weekend with high pressure located over the eastern US and lower pressures in West Texas. The pressure gradient looks weak but the persistent easterly fetch should keep seas slightly elevated. A weak cold front will cross the coastal waters late Sunday with winds remaining E-NE as high builds into the southern plains and then quickly moves east on Monday. A SE flow will develop Monday night on the backside of the retreating high. Onshore winds will persist through mid week ahead of another front that could cross the coastal waters late Wednesday. 43 && .PRELIMINARY POINT TEMPS/POPS...
