Area Forecast Discussion National Weather Service New Orleans LA 106 PM CDT Sun Apr 18 2021
UPDATE.
Forecast is mostly on track in the near term. Will likely be looking at the next rain system coming in a bit later on Friday than currently indicated, but will need to look at the 12z ECMWF operational run to see if it's slower trend is maintained.
AVIATION.
VFR conditions will prevail through Monday with only a few to scattered low level clouds at or above 3000 feet in afternoon and some mid to high clouds.
22/TD
PREV DISCUSSION. /issued 351 PM CDT Sun Apr 18 2021/
SYNOPSIS .
Frontal boundary now well south of our coastal waters. Southern stream shortwave should be exiting the CWA in the next few hours, with the northern stream shortwave dropping southeast through Kansas and Oklahoma. Main area of precipitation should also exit our eastern coastal waters with the shortwave. Temperatures generally mid 50s to lower 60s away from marine influences.
SHORT TERM (Through Tuesday) .
Almost seems hard to believe, but drier weather on tap for the area, with even some sunshine expected today. Precipitable water values that had been well over 1.5 inches are expected to drop below an inch by sunrise across most or all of the area. Already seeing a loss of low clouds across western portions of the area. Still some residual mid and high level moisture around, and as wet as the ground is, some flat strato-cumulus development during the heat of the day wouldn't be unexpected. Northern stream shortwave moves eastward to the east coast on Monday, followed by a southern stream shortwave ejecting across the area on Tuesday. NAM solution is an outlier solution with a more northern track of low pressure across the Gulf of Mexico, along with a stronger wind field. That solution would bring rain to eastern sections late Monday night and Tuesday. Either solution would bring cloud cover back to the area Monday afternoon into early Tuesday, but will keep the forecast mostly dry per the consensus.
Current NBM temperature forecast more closely resembles a GFS/ECMWF blend and is accepted with little change.
LONG TERM .
Very broad L/W trough will dominate the eastern half-2/3rds of the CONUS and it will send a cold front through the area Wednesday and this cooler drier air mass will quickly move in over the area Wednesday night and Thursday. Rather chilly temps for late April will impact the region with lows ranging from possibly the upper 30s to mid 50s Thursday morning. This drier cooler airmass will be very short lived though as the next s/w will already be moving into the desert southwest Thursday night and this will allow the region to moderate quickly. This s/w will move into the Plains on Friday and Friday night and could bring . ugh I don't want to say it . showers and thunderstorms back to the region again. /CAB/
AVIATION (valid through 12z Monday) .
All terminals have returned to VFR conditions, although can't rule out ceilings at KNEW briefly dropping into the MVFR range over the next few hours. Beyond mid-morning, expect VFR conditions to predominate, but could see some scattered clouds in the FL030-050 layer during max heating. May be a few northerly wind gusts to 20 knots at KNEW during the day and early evening hours.
MARINE .
Will carry Small Craft Exercise Caution headlines for most of the open coastal waters today, although northern portions of those zones will see winds relax later in the day. May need to extend those headlines for the outer waters tonight. Probably a brief lull in the winds this evening before cooler air reinforces briefly late tonight. By midday on Monday, a lighter wind regime moves in for about 24 hours as high pressure moves along the northern Gulf coast. Another reinforcement of cool, dry air will increase winds again Wednesday into Thursday, but may stay below advisory criteria.
