852 pm edt Thu jul 20 2017

Update Area 00z soundings showing very unstable conditions
beneath upper low... With decent cooling in 700mb-300mb layer...

supporting surface-cape values above 4,000 j kg. Radar has been
showing a considerable number of tall intense cores... With
conditions supporting hail and severe-level downburst winds.

Starting to see a decrease in coverage... Which should continue
through the evening. Have adjusted hourly pop weather grids for
expected evolution through the evening. Could see some patchy fog
late tonight... Especially where we've seen significant rainfall.

Aviation Vfr conditions expected... Could be some fog around
kgnv due to rainfall in the area... May need to be added to 06z
taf there.

Marine Surface ridge axis will remain south of the area through
early next week. We expect southwest flow through Saturday then
becoming southeast as the atlantic sea breeze develops. Seas will
generally remain in the 2 to 4 foot range with winds and seas
below small craft exercise caution criteria. Somewhat stronger
southwest flow Sunday through early next week may mute the east
coast sea breeze a bit... As a sfc trough and front push into the
carolinas and possibly north ga.

Rip currents: mainly low risk, though rip currents will be more
prevalent around piers and jetties.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
