Area Forecast Discussion National Weather Service Houston/Galveston TX 1254 PM CDT Wed Sep 23 2020

AVIATION [18Z TAF Issuance].

TD Beta has finally moved off and now we find ourselves on the back side of that low. Still going to see IFR and MVFR conditions but are looking to improve a bit today and some areas could even see VFR conditions. Late tonight and into the morning, however, IFR to LIFR CIGs are expected to form. Northerly to northwesterly winds are expected to prevail with a few gusty conditions this afternoon, then light over night. 35

PREV DISCUSSION /Issued 355 AM CDT Wed Sep 23 2020/.

SHORT TERM [Through Thursday Night].

Post-tropical storm Beta will slowly move eastward through the day today getting to the Lousiana border by the afternoon. Luckily the western side of Beta remains fairly rain-free, so our chance of rain drops once it get to the east of the area. This still leaves a chance of rain through the late morning for areas generally east of I-45. Rain rates within the bands have dropped considerably compared to yesterday, but saturated lands and slowly receding creeks and bayous may still lead to flooding potential for the eastern counties through the early morning. No longer expecting the widespread flooding threat, so the Flash Flood Watch has been cancelled. This evening through Thursday night will be relatively calm with not much of a chance or rain or any other significant weather.

High temperatures today and tomorrow will be on to cooler side with highs in the low 80s south of I-45 and in the upper 70s to the north. Lows will be in the upper 60s to low 70s both nights with the warmer temperatures closer to the coast.

Fowler

LONG TERM [Friday Through Wednesday].

Long term period will continue the relative quiet trend (no complaints here). An upper level low will be developing over Texas over the weekend, but we are not expecting much, if any shower activity from it. This is due to there not being much moisture for it to work with (PWATS down to around an inch) and convective temperatures will not be hit to trigger afternoon storms. The best chance (which is still slight) will happen Sunday afternoon near the coast as the upper level low moves off the coast providing some better upper level support. The aforementioned upper level low will be sliding eastward across the northern Gulf coast through midweek as its picked up by a digging trough that moves across the Great Lakes region. Now this trough may be able to give us the first shot at a decent cold front this season late Tuesday into Wednesday. Now this is the very end of the period and obviously things can and will change, but this cold front could be the one to get us into the fall season.

Fowler

MARINE.

Moderate to strong winds and elevated seas will continue today and tonight as Post-Tropical Cyclone Beta continues to slowly move further east into the Lower Mississippi Valley. Conditions will improve tonight with all bays and Gulf waters falling below SCEC/SCA criteria. Friday into early next week, winds generally between 5-10 KTS and seas between 1-3 FT can be expected.

Along the coasts, the Coastal Flood Warning will be allowed to expire at 7 AM CDT Wednesday (today) along the inner coastal regions of SE Texas. A Coastal Flood Advisory will replace the Coastal Flood Warning along the coastal area of Freeport westward into Matagorda Peninsula and will be in effect through Thursday morning. For the Galveston Island and Bolivar Peninsula, a Coastal Flood Warning will continue through at least Thursday morning. Also, it is likely that the Gulf facing beaches continue to experience rip currents.

24

TROPICAL.

Beta has become post tropical over southeast Texas and will continue to move northeastward towards Louisiana through this afternoon before dissipating. Elsewhere across the Atlantic Basin, Teddy and Paulette have also become post tropical.

As of writing this discussion, the NHC currently has no areas of potential tropical development in the next five days - which is a-okay with this forecaster.
