Synopsis
A front will linger near the coast through Tuesday. Deeper
moisture ahead of the front will remain east of the forecast
area. The pressure ridge behind the front will extend through
the region Wednesday with the front farther off the coast.

Diminished relative humidity will be associated with this
pattern. The ridge will be in the atlantic late in the week
and circulate increased moisture into the forecast area.

Near term through tonight
This morning's analysis showed dry advection from the north.

Convergence associated with the front near the coast should
remain east of the forecast area. The NAM and GFS mos and high-
resolution models support a dry forecast. The temperature
guidance was consistent.

Short term Tuesday through Wednesday
The models keep the front off the coast Tuesday but depict some
weak surface troughing lingering inland. There will be increased
moisture and instability associated with a mid-level shortwave
trough. The models have been consistent lowering h5 temperatures
to around -12 c. However, moisture should still remain limited
and the models depict just weak instability. Forecasted slight
chance pops mainly in the southeast section closer to deeper
moisture and a little greater convergence ahead of the weak
trough Tuesday afternoon and evening. The thunderstorm chance
should further diminish overnight with the loss of heating and
drying behind the mid-level shortwave trough. The models have
been consistent with dry ridging dominating Wednesday with the
front farther off the coast.

Long term Wednesday night through Sunday
The models show dry ridging dominating through Thursday.

Moisture will be on the increase Friday through the weekend as
the surface ridge shifts farther offshore with a return
southerly flow. A weakness in the upper ridging may help allow
an increased chance of mainly diurnal thunderstorms. The GFS and
ecmwf MOS support chance pops. The MOS indicates near normal
temperatures through the medium-range period.

Aviation 06z Monday through Friday
Convection has moved out of the area early this morning. Drier air
will continue to push into the area from the north this morning
behind a secondary front trough. Veil of mid and high level
cloudiness will continue streaming across the region this morning.

Latest cae VWP indicating a 20 kt LLJ early this morning. Some ifr
stratus has developed at ogb which may persist until around daybreak
when drier air should push in from the west. Some fog may also be
possible at ags before sunrise. Otherwise, expectVFR at all other
taf sites through 12z. After 12z, expectVFR conditions everywhere
for the remainder of the TAF period as drier air continues to spread
across the area.

Extended aviation outlook... No significant impacts to aviation
expected.

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.
