Area Forecast Discussion National Weather Service New Orleans LA Issued by National Weather Service Jacksonville FL 1130 PM CDT Mon Sep 21 2020

06Z AVIATION TAF PACKAGE.

Widespread IFR CIGS/VSBYS will develop at all TAF sites as moisture ahead of TS BETA overspreads the region and rainfall develops and becomes moderate to locally heavy at times. Still some chance of TSRA at KHUM and have included VCTS at 12z and predominant TSRA from 16Z-22Z time frame. East winds in the 8-14 knot range at the moment will increase to 12-20 knots with occasional gusts to 20-30 knots at times through the day on Tuesday.

PREV DISCUSSION. /issued 443 PM CDT Mon Sep 21 2020/

SHORT TERM (Tonight through Tuesday Night) .

Much to discuss to start off a new work week. Taking a quick synoptic overview across the southeastern United States places all focus on Tropical Storm Beta - soon to make landfall along the Texas coastline this afternoon/evening. East of Beta across the northern Gulf remains a strong southerly low to mid-level flow anchored in place helping to surge moisture north all across the northern Gulf coast. PW's remain anomalously high given today's 18Z KLIX RAOB analysis of 2.25" presenting a very evident moist- adiabatic thermal profile in place. Heavy rain and thunderstorms remains in place across coastal SE LA and adjacent marine areas. This mass of convection is confluent along a SE/NW oriented boundary/zone of surface moist convergence which has not been moving much. For tonight, this band may wobble some - particularly drift east along with Beta. The main focus for tomorrow is for where or if any additional mesoscale bands set up leading to training convection. Where exactly these bands set up is in doubt, as widespread 2 to 3 inches will be a general average within the current Flash Flood Watch but higher amounts upwards of 6 inches may be possible in some areas, especially south of I-10. WPC Day 2 ERO highlights the greatest focus for where these training bands will set up with a Moderate Risk across the Atchafalaya basin. Otherwise for the rest of tonight, gusty winds will persist. Most of the strongest winds remain along and just offshore coastal locations of southeastern Louisiana. However, breezy conditions remain in place along and south of I-10/12 where HRRR/NAM3KM guidance supports atleast advisory-level winds to persist. Because of this, have extended the Wind Advisory until midnight and to let later shifts cancel and/or extend if necessary. Additionally about Tuesday; expect similar cloudy/muggy conditions to persist with focus staying on if/where any heavy rain bands form along convergent moisture boundaries. Temperatures remain on the cooler side and have nudged just ever so slightly down against NBM guidance.

LONG TERM (Wednesday through Sunday) .

With Beta making landfall along coastal SE Texas, what is left of the circulation is forecast to take a turn and pull more to the northeast SE Texas/SW Louisiana. There remains a split in the guidance between CAM's and the global models where the CAM's keep the remnant low north of our area, while the GFS/ECMWF solution keeps the low tracking across southeastern LA. The difference in solutions will prove different scenarios across the area. If the remnant low tracks to our north, just enough low-level shear and deep moisture will provide the potential of a few rotating shallow cells leading to a few isolated tornadoes. This threat will be low along and north of where the low tracks so be advised as this may need to be monitored - especially if CAM's are right and keeps the low more towards the north. Regardless, expect ongoing bands of heavy rain/training cells to keep the flash flooding risk up through the day on Wednesday. Depending on the eventual speed of the low exiting the area will determine when we eventually clear up. Taking a blend of global guidance does slowly clear out conditions late week and into the weekend. However, this could be short lived as the next shortwave trough digs south across Texas (as indicated by trends in the GFS). This will again place the northern Gulf coast along the downstream divergent eastern section bringing back yet another risk of increased rain chances upcoming this weekend.

The good news is by early next week, this possible shortwave becomes absorbed by a stronger longwave trough digging deep across the east coast and pushes out, and will be followed by a strong, progressive NW to SE flow aloft. This will support strong upper- level divergence/ surface high pressure (1026mb+) and may actually deliver a cooler/drier shot of air following a strong cold front. Fingers crossed. KLG

MARINE .

Many impacts remain in place across all marine zones - including the continued threat for strong winds. Latest platform observations have indicated winds to be just narrowly at or slightly below sustained tropical storm force which has allowed for a cancellation of the Tropical Storm Warning. Now, all zones are under a Small Craft Advisory mentioning strong winds 25-30 knots continuing, with gusts to Tropical storm force remaining possible especially overnight. Easterly strong winds will continue through Tuesday and even into Wednesday where Small Craft Advisory conditions will prevail. Additional threats will include high/rough seas with wave heights ranging 10-12 feet for 20-60nm zones, 3-5 near coastal to 4-6 feet outer to 20nm. Protected waters will remain less, but range generally 2-4 feet before conditions steadily improve late Wednesday and especially on Thursday. Long fetch winds will keep waves and seas up to atleast 5-7 feet for outer waters on Thursday, but steadily lower and improve through late week.

Other concerns continue to be coastal flooding problems with Coastal Flood Warnings in effect. Advisories follow thereafter as impacts do improve beginning later Tuesday after high tide cycle. Minor, nuisance coastal flooding will continue atleast through Thursday but an overall improvement in conditions should begin starting Tuesday. KLG
