short term tonight through Tuesday night ...

cold front currently stretches from the mid atlantic states back
through the lower mississippi river valley. This front will continue
to move eastward overnight and through the remainder of the cwfa
during the day on Tuesday. Not a lot of moisture associated with the
front. Clouds will increase late this afternoon and evening with
isolated scattered light shra are possible across the far northern
cwfa. Otherwise, only a few sprinkles are expected.

Cooler temps are also expected behind the front as high pressure
builds in from the west. Below normal min MAX values are likely,
ranging from 5 to 10 degrees below normal.

Nlistemaa
long term Wednesday through Monday ...

mainly only tweaks to the long term based on the latest guidance.

A dry Wednesday and thanksgiving day is still expected followed
by a wet Friday into Saturday.

previous discussion...

extended models are in good agreement with surface high pressure
and near zonal upper level flow through Thursday. Thanksgiving
remains dry with temperatures in the mid 50s to lower 60s. Models
begin to diverge on Friday with the evolution of a developing
wave upper low over the southern plains and the associated cold
front which will track across the gulf coast states through
Saturday. ECMWF is more progressive than GFS which brings a
secondary surface low just north of forecast area on Sunday. Have
kept chance showers as the front moves through the area, with
little instability noted. Temperatures will remain below normal
through the period.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
