Synopsis
High pressure will maintain fair weather through Friday. A frontal
boundary will move into the region, and provide a chance of showers
and possible thunderstorms, mainly late Saturday night and Sunday.

Another front will move through Tuesday.

Near term /until 7 am Friday morning/
High pressure centered over the middle atlantic states this
afternoon will be off the coast tonight. More of an onshore
flow will develop in the forecast area as the high shifts
eastward. The significant moisture will remain shallow and
confined to the low levels because of upper ridging moving into
the area from the west. Expect stratocumulus at times under the
subsidence inversion. Leaned toward the more consistent GFS and
ecmwf MOS for the temperature forecast. Expect lows in the
middle and upper 30s in the north section tonight. However, the
chance of frost is low because of some mixing plus the models
suggest a 10-degree temperature-dew point temperature spread.

Short term /7 am Friday morning through Saturday night/
Surface high will begin to slowly weaken and shift slightly east
Friday, providing some moderation in temps/dewpoints. Upper ridge
over the area and strong subsidence expected. Weak isentropic lift
and moisture recovery may provide some stratus, possible fog, late
fri nt/sat morning. Deep low in the midwest will be moving slowly
east-northeast Saturday. Moisture continues to increase Saturday
with upper ridge weakening and shifting southeast... But lift mainly
west of the region and expect any showers to remain west of the
region through the afternoon. Continued warming trend.

Long term /Sunday through Thursday/
Closed upper low, and surface low, to shift NE from the central
plains to the great lakes, with upper trough axis approaching our
region Sat nt and moving through Sunday. Best upper dynamics to
remain to our north, but chance pops with possible thunderstorms
expected in weakly unstable air mass. Another upper trough/front
appears will move through Tuesday.

Aviation /00z Friday through Tuesday/
Vfr conditions are forecast through the TAF period but it is
possible MVFR ceilings may develop during the early morning
hours.

Onshore flow will increase low-level moisture as upper ridging
moves in from the west. ExpectVFR stratocumulus and possible
MVFR at times under the subsidence inversion after 06z and
lasting through 18z on Friday. The fog chance appears limited
by boundary layer mixing and the MOS forecast of significant
temperature-dew point temperature spread. Followed the GFS and
nam MOS and forecasted wind east to southeast 10 knots or less.

Extended aviation outlook... Restrictions may occur Saturday
morning in fog and stratus associated with an onshore flow.

Deeper moisture and a frontal system near the area may help
support scattered showers and thunderstorms with associated
restrictions Sunday and Monday.

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.
