Area Forecast Discussion National Weather Service New Orleans LA 152 PM CDT Thu Oct 28 2021

AVIATION. VFR conditions will prevail as skies remain SKC through 00z. Winds will gust in access of 35 knots at NEW, MSY and HUM this afternoon. Ceilings will drop tonight as a BKN to OVC mid-level cloud deck rolls in and will remain in place through at least 18Z Friday.

PREV DISCUSSION. /issued 337 AM CDT Thu Oct 28 2021/

SHORT TERM (Thursday through Saturday night) . With the severe weather behind us the rest of the forecast will be mostly focused on temperatures. Breezy conditions will remain in place today with winds sustained near 25mph through the day. A Wind Advisory is in effect for the entire area from 11am this morning through 7pm tonight. Cyclonic flow associated with an upper level low moving east across the area will aid in an increase in cloud cover and ultimately, cooler afternoon temperatures. Overnight lows will be in the upper 40s to low 50s through the weekend. At the same time high pressure will begin to build in on the backside allowing for PoPs to fall to near 0 across the area, meaning much drier weather conditions for the weekend. /TDB/

LONG TERM (Sunday through Wednesday .

The beginning of the long term forecast will be rather quiet and dry as the upper level low pressure system continues to move off to the east coast Sunday. A surface high pressure system will help to keep PoPs nearly non-existent days 4-6 as a good amount of dry air hangs around our region. We'll see cooler temperatures through early next week as high temps sit in the mid 70s for most areas with low temps in the upper 40s to low 50s for northern parts of the CWA and the mid 50s to low 60s closer to the coast.

Heading into Wednesday we'll see our next weather maker approach the region with an upper level longwave trough over the Great Lakes region. Both the GFS and ECMWF bring moisture into our CWA with this system, but with it being day 7-8 changes to the forecast are to come. For now we have PoPs forecast to gradually fill into our CWA late Wednesday. -HL

Aviation (06Z Taf Cycle) . VFR conditions have returned for all terminals. Can expect frequent gusty winds through the overnight hours and possibly lasting through the day today. Otherwise, drier weather conditions are forecast for the remainder of the period. /TDB/

Marine . Winds will continue to be a threat over the coastal waters with W/NW winds reaching gale force conditions. Sustained winds up to near 35kts with wind gusts near 50kts are forecast through at least mid day Friday. Gale Warning will be in effect from 12z today through 18Z on Friday to account for gale conditions. Small Craft Advisory remains in effect through 12z this morning and then will be in effect again on Friday at 18z through 12z Saturday. There may be a need to extend the Small Craft Advisory a few more hours on Saturday as winds currently look to still remain elevated, but will continue to monitor conditions closely in the next day or two before making a final decision. By Sunday, high pressure will be the dominate feature and winds will return to near 5 to 10kts with waveheights dropping back down to 2 to 3 ft. /TDB/
