805 am edt Thu may 23 2019

Update Very impressive upper high over the forecast area. Jax
morning sounding has 500mb height value of 593.6... Close to record
for may. At surface, high pressure will build southward from just
off mid-atlantic coast. Result is somewhat enhanced easterly flow
which will lower high temps a few degrees today compared to
yesterday, but still quite toasty with highs in the lower to mid
90s well inland... Upper 80s near 90 eastern counties... Mid 80s
coast. Strong subsidence expected to prevent anything more than an
isolated shower... Thus have limited pops today to 10 pct. Breezy
conditions are expected across coastal counties later today.

Aviation A few areas of MVFR CIGS were observed earlier
this morning... But generallyVFR conditions expected today
with 10-15 kt easterly surface winds.

Marine
No changes expected in next cwf issuance. Strong high pressure
along the mid-atlantic coast this morning will gradually weaken
as it shifts southward tonight and Friday. A tight pressure
gradient will keep breezy easterly winds in place through this
evening near shore and offshore, with speeds remaining just below
caution levels. Seas of 4-5 feet are expected offshore and 3-4
feet near shore through this evening. Winds and seas will then
begin to decrease towards midnight as our local pressure gradient
weakens and high pressure builds directly over our waters.

Rip currents: breezy onshore winds will combine with the outgoing
tide this afternoon to create a moderate risk at all beaches
today. A low risk appears likely for Friday and Saturday as winds
decrease. An increasing risk is then expected by memorial day as
a long period northeasterly swell arrives.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
