Summary: Flat, low white and grey stratus clouds looked to cover most of the sky through until sometime during the afternoon. The sky looked to be mostly clear, or maybe clear during the evening and night. The wind speeds looked to be calm with light gusts. I did not see, or hear about any rain falling anywhere in, or near the Houston, TX area, during anytime of the day. I did not see, or feel any rain drops, where I was, during anytime of the day. It felt a little cool, during the early and mid-morning. It felt warm during the late morning, afternoon, evening, and night.

000 FXUS64 KHGX 052353 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 553 PM CST Thu Nov 5 2020 .AVIATION [00Z TAF Issuance]... Patchy fog setting up for most terminals tonight and settling in through the morning. For now, only looking MVFR conditions for now but IFR could happen at the terminals. Low moisture capping and just the right amount of wind speed could start the mixing process a bit sooner and set the fog up thicker. Later amendments could be needed as we see how it sets up initially. 35 && .PREV DISCUSSION /Issued 318 PM CST Thu Nov 5 2020/... .SHORT TERM [through Friday Night]... A warm and humid Gulf airmass has resulted in afternoon temperatures in the upper 70s to lower 80s this afternoon. Dewpoints have slightly increased; but still remain comfortable with values in the 50s and lower 60s. Dry conditions will continue to dominate throughout the short term period. The shortwave trough aloft will stall over the region tonight and linger into the weekend. Forcing remains weak and moisture is limited with PWATS still remaining below an inch. Therefore, precipitation is not expected. The exception will be over the Gulf waters where a surge of low-level moisture moves in thanks to persistent easterly flow. This will allow for isolated showers offshore Friday night into the weekend. The main concern tonight will be fog development/low clouds, leading to low visibilities at times. Hi-Res models and SREF probabilities highlight areas of low visibility west of I-45, although confidence in extent and coverage is still moderate. Will continue to monitor the potential for an advisory this evening/overnight. South to southeast winds will transition to the northeast by Friday (inland), bringing slightly cooler temperatures compared to today`s highs. Highs will mainly range in the upper 70s. .LONG TERM [Saturday through Thursday]... An upper level low cut off from the main flow will meander over TX through the weekend before getting sheared out as it moves to the NE. Upper level ridging will then amplify over East Texas and expand across the western Gulf as another long wave trough moves toward the inter-mountain west. PW values over the weekend look very dry and barely reach 1.10 inches. Capping is noted in the the 850-700 mb layer and 850 temperatures slowly warm through the weekend with MaxT values slowly warming into the lower 80`s by Sunday. Overnight low temperatures will also warm quite a bit with more cloud cover to insulate and a bit of mixing as winds don`t fully decouple. Next week looks unseasonably warm with 850 mb temps between 14.5 and 17.0 C. The long wave trough over the west moves east quickly and surface low pressure associated with the upper level feature will race NE and drag a cold front into the state. Pressure rises associated with the front look weak and current thinking is that the front will probably stall across SE TX. That said, there could still be a wind shift to the NE as whatever is left of Eta could be moving toward the central Gulf and the wind field associated with this feature should allow for winds to become NE and drier air on the west side of the feature should allow skies to clear late Tuesday into Wednesday. Despite strong capping in the 850-700 mb layer and a lot of dry air above 700 mb, there is a small saturated layer in the 930-850 mb layer and there could be a few streamer showers occasionally squeezed out Sunday night through early Tuesday. Most locations will likely stay dry. Pressures begin to fall again as low pressure develops over the TX panhandle on Thursday as a short wave trough develops over the western US and moves toward the Southern Rockies. The short wave trough will deepen as it crosses TX next Fri/Sat and it will foster the development of a sfc low near the coast and this feature will bring a chance of rain and a wind shift for the first half of next weekend. .MARINE... While the region continues to be dominated by a surface high over the northeastern CONUS, will continue to monitor for the possible arrival of Tropical Cyclone Eta across the southeastern Gulf of Mexico late this weekend into early next week as increased swells may be possible over our offshore waters. With that said, light easterly winds this afternoon will shift to the northeast and slightly increase overnight into Friday. Building seas from 5 to 6 ft offshore and gusts around 15 to 25 knots will be possible Friday afternoon into the early next week. Isolated to scattered showers are also expected far offshore. Small Craft Should Exercise Caution conditions or Small Craft Advisories will be possible Friday into the weekend. && .PRELIMINARY POINT TEMPS/POPS...
