Update
Broad upper level troughing continues across the eastern u.S.For
the next 24 hours or so. One embedded short wave trough over the
mid-atlantic states slips offshore Tue while a second S W trough
tracks from the nm tx border to the central gulf coast by tue
afternoon. At the surface high pressure in the ohio valley moves
to the new england and mid-atlantic coasts tue. A stalled front
reaches from the gulf of mexico to the atlantic - just south of
the florida keys - as a weak low pressure center slides along it.

The features noted above will provide a moisture rich southwest and
west flow aloft and a coolish northeasterly low level flow... Robust
at times. Overcast clouds will slowly lower as large areas of
showers and rain on the gulf... Already moving onshore will stream
across tonight and much of tue. The greatest coverage will generally
be south of the i-4 corridor... Where the most moisture. Temperatures
will be near normal overnight but on the cool side Tue thanks to
clouds and rainfall. Forecasts are in good shape overall but will
make minor adjustments to the near term to better reflect ongoing
trends.

begins to relax Wed and allow winds to diminish through the end of

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.
