| Area Forecast Discussion National Weather Service New Orleans LA 347am CDT Wednesday Oct 21 2020 Short Term High pressure ridging in from the NE will maintain control of the weather for this area through Thursday with not much of any precipitation to speak of. Some patchy fog at a few sites by sunrise. Long Term Precipitation may linger into Friday night before shortwave ridging limits further rain chances through the weekend. Beyond the weekend, medium range models begin to have issues regarding upper system moving out of the 4 Corners area. GFS solution is much quicker in opening and ejecting wave eastward. For example, at 18z next Wednesday, GFS has upper ridging off the Carolina coast with the upper system over the Texas Panhandle. ECMWF (European Centre for Medium-Range Weather Forecasts) solution has upper ridging just about overtop of our area with the upper low near Phoenix. Quite a difference in sensible weather as we get into the mid and latter portions of the week, somewhat beyond the forecast period. For now, will keep low mention of precipitation for Monday and Tuesday with well above normal temperatures continuing. NOAA New Orleans LA Office: Watches - Warnings - Advisories LA...None.
