AVIATION.

Forecast soundings continue to support the idea that drier air to the west will get advected into SE TX later this afternoon and drier air aloft will begin to mix down as well so clouds are expected to decrease this afternoon. That said, visibile satellite imagery shows thick cloud cover continuing to rotate into the region from the east. Have leaned toward the clouds eroding this afternoon but timing is going to be tough. Some MVFR ceilings will redevelop toward morning over mainly eastern TAF sites but should mix out quicker than today. Have some concern that the cigs won't develop and if that occurs, conds look favorable for some fog and this could get locally dense in a few spots. Winds remain light through the TAF period. 43

PREV DISCUSSION. /ISSUED 457 AM CDT Thu Sep 16 2021/

SHORT TERM [Today through Friday Night] .

Post tropical Nicholas wobbling around near the LA coast in the vicinity of Marsh Island. Circulation of Nicholas still impacting SETX with light N/NE winds and bringing in stratus deck from the east and will continue wrap around through the areas east of the I- 45 corridor and probably down over the coastal areas southwest of the Metro. The cloud deck should erode through the late morning/early afternoon hours with temperatures quickly responding and climbing into the 86-91 degree range inland. Coastal areas should still reach the mid 80s. Rain chances still linger in the east albeit slim with sprinkles and light showers beneath the cap. Winds decouple in the evening and skies clear out though some cirrus may speckle the area. Patchy fog will be possible toward morning Friday near sunrise but at this point probably at the rural sites mainly north of the I-10 corridor. On Friday the north winds relax and a seabreeze should develop and spread inland late afternoon with not only a moderate expanse of CU field but also some cirrus as upper low slips int the north-central portions of TX. Rain chances should still be low over the east even with the approach of the upper disturbance. Loss of heating in the evening should curtail the convective development but as upper low meanders closer late in the evening then early Saturday morning rain chances should ramp up as the cooling aloft and low level convergence increases. Threat for thunderstorms near the coast should be on the increase. 45

LONG TERM [Saturday Through Thursday] .

The combination of wraparound moisture from the remnants of Nicholas and a weak upper-level low will lead to steady PoPs over the weekend. These will be of our usual variety with showers/thunderstorms along the seabreeze, but coverage should be slightly higher east of I-45 and offshore where there is more moisture availability. The deeper moisture associated with the remnants of Nicholas that remains in the northern Gulf will slowly ease back in early next week with the advent of surface high pressure developing in the eastern Gulf. Onshore flow develops leading to moisture advection and increasing PW values (1.8"-2.2") for at least the southern half of the CWA. There is a little uncertainty on this though since all three of the global models offer different solutions (ECMWF doesn't bring in the deep moisture at all). Ended up only using "likely" PoPs for the Gulf waters since the moisture should at least make it to the coastline. Uncertainty with PoPs goes into next week as a cold front attempts to push through SE Texas. Temperatures prior to this will be right around normal with highs in the uppers 80s/low 90s and lows in the 70s.

Oh FROPA, FROPA! Wherefore art thou, FROPA? That is the magic question isn't it Well. there is increasing confidence that a cold front will make its way into SE Texas midweek. Global models are in consensus that the cold front will be on the doorstep of our northern counties on Wednesday morning, but things diverge a little bit after that. The upper-level trough driving the cold front is much deeper on the 00z runs of the ECMWF and Canadian, thus the cold front pushes through. On the 00z GFS, a cutoff low develops over the Northern Plains which keeps the trough from deepening far enough south to push the front all the way through or washes it out as it passes through. There is consistency though that with moisture out ahead of the front, the convergence along the frontal boundary will lead to showers/thunderstorms as it pushes in. After Wednesday afternoon, PoPs are uncertain since the ECMWF/Canadian dry us out following FROPA, while the GFS leaves lingering moisture over the area as the front washes out. Going with 20% PoPs for now through Thursday. Did a little wishcasting on Wednesday night and Thursday night and went a few degrees below guidance to suggest that I'm onboard with the front making it through. There won't be significant cold air behind the front, but I think we could at least see low 60s overnight for our northern counties. Speaking things into existence works right?

Batiste

MARINE .

Light northerly winds will continue to prevail through the end of the week before becoming southeasterly as high pressure builds in the eastern Gulf. Onshore flow and isolated to scattered showers and thunderstorms are expected Friday through next week as Gulf moisture increases. Onshore flow becomes increasingly moderate over the weekend leading to a slight rise in wave heights (increasing to 3-4 feet) going into early next week.
