Area Forecast Discussion National Weather Service Houston/Galveston TX 1141 PM CDT Sun Sep 19 2021

AVIATION [06Z TAF Issuance].

Overall, mainly VFR conditions are expected to persist through the duration of the TAF period. While skies remain generally clear at the time of issuance, winds remain slightly elevated compared to last night. Model soundings and SREF probabilistic guidance continue to support the potential for patchy MVFR fog, but development will remain inhibited if winds remain elevated above initially forecast levels. Have backed off slightly in this TAF package, keeping in 6SM wording but removing mention of sub-VFR visibility overnight. Fog should lift with the introduction of daytime heating. With the dominant upper trough axis continuing to shift further northeast, precipitation coverage will continue its decreasing trend. That being said, latest hi-res guidance indicated a bit more development along the coast and as a result have included VCSH wording across the metro and southern terminals.

PREV DISCUSSION /Issued 703 PM CDT Sun Sep 19 2021/.

SHORT TERM [Through Monday Night]. Scattered precip should come to an end by early evening. With mostly clear skies and light winds, we could see some patchy fog development late tonight . mainly w/nw of the metro area. It should burn off quickly after sunrise Monday.

500mb trof axis should be situated further east tomorrow. Lower moisture availability and increased subsidence aloft will keep precip chances/coverage even lower than what we've seen today. A drier southwesterly llvl flow should allow temps to climb well into the 90s across most of the region & perhaps the upper 90s to near 100 across parts of the Brazos Valley.

Majority of inland locations will see their last night with lows in the 70s Monday night . 47

LONG TERM [Tuesday Through Sunday]. Break out the pumpkin spice as Tuesday looks to be the last in our stretch of seasonably warm and humid days as a long awaited pattern shift and first real autumn cool front moves into the area. Haven't had to make many changes with the current forecast as we see another day with highs in the mid 90s Tuesday, although increasing clouds and rain chances late in the day could make max T forecasts a bit tricky. Appears front will move into the B/CS region in the late afternoon and progress south across the rest of the area through the evening and offshore by midnight. This will be a long awaited Fall- like airmass with dew points dropping into the lower 50s up north and into the lower 60s along the coast by Wednesday afternoon. Along with clearing skies, this will dip overnight lows to the coolest of the season thus far. Lows will drop into the 50s near B/CS and into the lower 60s even near the coast.

MARINE. No significant changes to the ongoing fcst. SSW flow will become better established tonight into Monday night. May see speeds reach 15kt offshore at times tonight and again Mon night, but am not expecting much higher than that nor a significant bump in seas due to the relatively short duration. Cold front is still on target to push off the coast Tue night accompanied by some showers and thunderstorms followed by moderate, gusty n/ne winds and building seas in its wake. Anticipate SCAs Wed and perhaps Wed night into Thurs morning offshore with the cooler air moving over the warmer water. Winds and seas will gradually diminish and trend more to the east heading into late week. 47
