Area Forecast Discussion National Weather Service New Orleans LA 327 PM CST Fri Feb 21 2020

Discussion .

1036 mb Arctic High pressure over western Tennessee bringing cold and dry conditions to the region for the next 24 hours. Freeze Warning tonight for northern zones of Louisiana and all of LIX Mississippi forecast counties. Surface High will move to the east of the CWA while an upper level ridge will temporarily pass overhead during the middle part of the weekend. This will bring a gradual warming trend with temperatures back to near average and dry conditions lasting through Sunday. Showers and isolated thunderstorms will be on the increase by Monday as a potent closed upper level trough over northeastern Oklahoma deepens and moves eastward dragging an associated cold front into the Arklatex by Monday morning. The threat of showers and isolated storms will continue through Monday night and possibly linger into the early part of Tuesday as strong surface low moves along the Ohio and Tennessee River valleys early next week. Another Arctic blast possible to likely by the middle and latter part of next week as a deep upper level longwave trough sets up over the Mississippi River valley bringing potentially some of the coldest air of the season along with it. Dry and well below normal conditions will prevail though the remainder of the forecast period from Wednesday and beyond.


AVIATION. North winds at all terminals with gusty winds up to 20 to 25 mph at NEW and MSY through late afternoon with winds tapering to less than 10 to 15 at NEW and MSY to light and variable at remaining TAF sites after 00z this evening. SKC will dominate sky conditions with VFR conditions prevailing the remainder of period.

MARINE. Small Craft Advisory will expire at 6 PM for the coastal waters. Offshore flow will continue to weaken through Saturday. High pressure will remain in place through the weekend. Surface High will move off the Carolina Coast by Sunday evening bringing a light return flow. Return flow will remain in place through early week until another arctic front moves through by the middle of next week. This will likely bring a minimum of Small Craft Advisory conditions to all waters once again.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
