Synopsis
The forecast area will be between maria slowly lifting farther
northeast of the area and a cold front approaching from the
west through Thursday. Warm and dry conditions will be
associated with this pattern. The cold front will move into the
area Thursday night and then stall just south of the area over
the weekend. Little moisture will be associated with the frontal
passage. Temperatures will lower to near normal just behind the
front this weekend.

Near term through tonight
Maria will be slowly lifting farther northeast of the forecast
area. Some wrap-around stratocumulus and cirrus will affect
mainly the northeast section. Do not expect showers with just
shallow moisture and relatively warm mid-level temperatures.

Followed the higher guidance temperatures because of the warm
air mass with h5 temperatures about -5 c. The NAM and GFS mos
supported north wind 5 to 10 mph in the west and 10 to 15 mph in
the east today with light north wind across the region tonight.

Short term Wednesday through Thursday
It should remain warm and dry. Maria will be lifting
northeastward slowly and farther away from the forecast area. An
approaching cold front should be nearing the area late
Thursday. Little moisture or convergence will occur ahead of the
front because of the northerly flow into the forecast area on
the periphery of maria. The nam, gfs, and ECMWF mos had pops
less than 20 percent. Followed the higher temperature guidance
because of the warm air mass with h5 temperatures around -4 c.

Long term Thursday night through Monday
The moisture limited cold front will be in the area Thursday
night. The front may linger in the area with some moisture
recovery mainly in the south section Friday. There should also
be some cooling aloft ahead of upper troughing. Forecasted a
small thunderstorm chance mainly in the south section Friday.

Saturday through Monday may be drier behind the front but a
tight moisture gradient just to the south adds uncertainty to
the forecast. The GFS and ECMWF ensemble guidance had a high
spread and indicated pops 5 to 50 percent. We forecasted a pop
close to the mean of 10 percent north to 20 percent south.

Aviation 12z Tuesday through Saturday
Hurricane maria will slowly move north and northeast today and
tonight staying off the north carolina coast. High pressure will
ridge into the area at the surface promoting warm and dry
weather. A 15 knot low level jet and dewpoint depression values
of greater than 5 degrees have helped prevent any fog
development early this morning at the terminals. Satellite
imagery shows stratus has dissipated and shifted south of the
terminals this morning, so have removed mention of both fog and
stratus.VFR conditions throughout the day with dry and warm
weather. Winds will be light and out of the north. Models show
potential for restrictions in fog stratus again early Wednesday
morning given mostly clear skies and light winds. Confidence is
too low to include in current issuance, but will continue to
monitor the threat.

Extended aviation outlook... No significant impacts to aviation
expected Wednesday through Saturday.

Cae watches warnings advisories
Ga... None.

Sc... None.

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.
