Synopsis
Another cool night is expected under clear skies and light
winds, as readings fall to near freezing with high pressure
overhead. Southerly winds on Tuesday will bring in even warmer
air, with afternoon highs expected to climb into the mid to
upper 60s away from the immediate shoreline. As we head into
Wednesday unsettled weather returns with the approach of our
next storm system. This system will slowly exit the region
Thursday. Beyond that, another fast moving system may be in the
cards for the end of the week. Cool, canadian high pressure will
follow.

Near term through Tuesday
6pm update... High pressure still in place. The sea breeze has
pushed quite far inland, almost to izg and lew in maine and
into con in new hampshire. Have updated winds to reflect this.

Prev disc... High pressure will remain overhead tonight with
clear skies and relatively light winds. With low dew point
values continuing across the region, expect large diurnal ranges
to continue. Temperatures will drop into the 30s in most areas
which will be a couple degrees warmer than last night.

Short term Tuesday night
Warm air will continue to advect into the region on
southwesterly winds on Tuesday. H8 temperatures will top out at
+6c. This will allow temperatures to quickly climb into the 60s.

Along the immediate coastline, temperatures will be cooler,
especially along the midcoast region where temperatures will
drop off in the afternoon due to an onshore component to the
flow.

A large and slow moving low pressure system will begin to
advance northward Tuesday into Tuesday night. Rain will spread
north as the flow becomes southeast off the atlantic, allowing
plenty of moisture to enter the region very late at night. This
will set the stage for some soggy conditions in the extended
portion of the forecast.

Long term Wednesday through Monday
A strong upper short wave moves to the mid atlantic coast wed
morning spawning a surface low near DELMARVA that will move
northeast late Wed and Wed night. This will spread a soaking
rain across the region Wed into Wed night with between .75-1.50
inches of rain with some locally higher amounts. Warmer
temperatures in advance will allow for some melting of snow in
the headwaters. That combined with the rainfall may bring some
area river flows to near flood stage.

The surface upper trof lifts northeast Thu toward the maritimes
allowing instability showers to stick around due to the cold
pool aloft combining with some surface heating allowing
steepening lapse rates helping enhance scattered shower
development. Thu night into early Fri a short wave ridge briefly
brings clearing to the area.

By Fri afternoon another trof gets carved out across the eastern
u.S. Bringing unstable air spreading more showers into the area
by Fri night into early sat. The system exits Saturday but
leaves a colder cyclonic northwest flow in its wake... This will
mean scattered afternoon showers can be expected to redevelop
once again.

A ridge of high pres slowly amplifies and builds into the area
Sunday so dry conditions expected.

Generally temperatures can be expected to be near or slightly
below normal for most of the outlook period.

Aviation 22z Monday through Saturday
Short term... Light winds and mainly clear skies will continue.

Low dew point values should prevent fog from forming in most
areas. Onshore winds expected to increase Tue afternoon.

Long term... Ifr conditions expected Wed into Thursday morning.

Conditions then improve toVFR but with sct MVFR conditions in
sct -shra.VFR conditions return Thu night and fri.

Marine
Short term... Winds and seas will remain below SCA thresholds.

However, winds and seas will be on the increase Tuesday night.

Long term... Onshore flow will be strong enough to produce sca
conditions over the outer waters Wed into Wed night and then
winds diminish and shift to the west Thu in the wake of the low.

Seas will be slow to get knocked down and subside Thu over the
outer waters.

Fire weather
Elevated fire weather conditions will continue through sunset
due to very dry atmospheric conditions. However, winds in most
areas will remain relatively light, with sea breezes near the
coastline.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

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.
