short term tonight through Monday night ...

quiet fcst period continues with dry and abnormally warm airmass due
to amplified ridging and likely even some aided subsidence from
hurricane maria off the southeast coast. Could see some patchy early
morning fog again given the radiational cooling overnight, otherwise
should be mostly clear with some scattered cirrus skirting the upper
levels. Highs looks similar for tomorrow afternoon as to today,
which should persist near 5 degrees above climo (mid to upper 80s
for most locations).

long term Tuesday through Sunday ...

extended forecast largely on track with dry conditions through much
of the week with only low pops and a return to near normal
temperatures Friday and Saturday as pronounced ridge of high pressure
begins to break down. Have made minor adjustments to temperatures
and dewpoints beyond day 5 to account for latest model
trends. Previous forecast discussion follows...

prev discussion... Issued 735 am edt Sun sep 24 2017
long term Monday night through Saturday ...

no significant changes made once again through the extended forecast
period as the medium range model trends remain fairly consistent with
recent runs. Still looking at dry and above seasonal normal
temperatures through the work week as the region remains under weak
upper ridging with persistent northeasterly low-level flow
maintaining a stable airmass over the forecast area. Will see milder
temperatures and at least a slight chance for precipitation returning
as we head into the weekend as the upper ridge breaks down. Still
not seeing any impressive upper dynamics or low-level support for
higher pops.

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.
