What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Issued at 256 am edt Thu may 24 2018
high pressure will bring fair weather today and Friday then weak
low pressure will spread some clouds and the chance for showers
and thunderstorms over the weekend.

Short term (today through Saturday)
issued at 256 am edt Thu may 24 2018
forecast issue in the near term is timing and coverage of showers
and thunderstorms from late Friday through Saturday. The trend is
for a slightly slower arrival with only a slight chance across the
northwest fringe of the forecast area on Friday afternoon and
reaching the southeast zones by late Friday night.

Instability and shear are weak so no severe storms are expected
but pwats increase to about 1.5 inches Friday night and Saturday
and isolated heavy downpours are possible.

Long term (Saturday night through Wednesday)
issued at 256 am edt Thu may 24 2018
very mild and rather humid wx will continue through the holiday
weekend with high temperatures in the 80s. There is potential for a
few showers and thunderstorms to develop Sunday mainly during the
afternoon and early evening as instability builds and with some
forcing from a backdoor cold front. However most of the day should
be dry.

A high pressure ridge will build in for the early to middle portion
of next week bringing fair wx with seasonably mild temps. There is
still a small chance for subtropical moisture to move up into our
region late Wednesday or Thursday. However confidence in this
occurring is low given large medium range guidance discrepancies
regarding the evolution and eventual movement of the remnants of the
potential tropical system over the gulf coast region this weekend
into early next week.

Aviation (for the 12z tafs through 12z Friday morning)
issued at 732 am edt Thu may 24 2018
vfr conditions will continue through tonight with south to
southwest winds under 10 knots. There could be patchy shallow fog
late tonight but this is left out of the forecast since the
chances are low.

Marine
Issued at 256 am edt Thu may 24 2018
dense fog is still a possibility through the morning but the worst
of it is currently remaining well offshore. Winds and waves will
remain relatively light today and tonight with some increase on
Friday as south winds increase to 15 to 20 knots.

Hydrology
Issued at 318 pm edt Wed may 23 2018
rivers will continue to fall slowly for the next couple of days.

Significant rainfall is not expected.

Grr watches warnings advisories
Mi... None.

Lm... Dense fog advisory until 11 am edt this morning for lmz844>849.

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.
