Synopsis
Primary low pressure over the great lakes will track into
southern canada tonight while secondary low pressure will move
up the atlantic coast. High pressure returns briefly on
Thursday. A cold front will cross the region Thursday evening
and stall to the south on Friday. Another large and complex low
pressure system will move northeast across the region Saturday
into Sunday.

Near term through Thursday
Warm air has spead cross the region today aloft, with most
precipitation now mainly in the form of sleet, freezing rain and
plain rain where temps have risen above freezing. There are
still significant pockets of sub-freezing air across the i-95
corridor, but these are likely to dwindle over the next several
hours, so freezing rain is likely to change to rain as the
evening progresses. Temps will struggle further northwest in the
i-81 corridor, so warnings remain in effect until after midnight
in these areas.

Precip should clear the region late tonight, but low clouds may
linger into the morning hours. After westerly winds kick in,
temps should surge as clouds break, with many areas likely to
touch 50. Will have to watch out for potential for the low
clouds to linger longer than expected, but otherwise, Thursday
should be much nicer than today.

Short term Thursday night through Friday night
Weak front crosses the region late Thursday afternoon evening,
perhaps with some showers or a little rain, especially in
central va. Cooler air will move in for Friday behind this
front, with temps closer to seasonable norms (40s). With the
front stalling just to the south, some rain may linger in
central va. Complex low pressure will then start to organize to
the southwest, sending warm advection our way Friday night. Will
need to watch temps closely Friday night as the rain oversprads
the region again, as northern areas could slip below freezing
overnight and result in some freezing rain. Temps will
generally be in the 30s Friday night.

Long term Saturday through Wednesday
A warm front will approach the region from the south on
Saturday. Overrunning precipitation ahead of the warm front is
forecast to start affecting our region as early as Friday
evening.Winds will be mainly out of the south behind the warm
front leading to advection of warm and moist air into our
region. As the warm front shifts northward and moves our our
region, the models are trying to transfer energy from the
surface low too form a secondary low along the warm front that
shifts eastward to the eastern seaboard near the mid-atlantic
coast. This would lead to increased precipitation focused over
our region. Models indicate the potential for over a inch of
liquid during the warm front transition northward. The warm
front is forecast to shift to our north as the cold front
approaches from the west early on Sunday. The cold front is
expected to move through our region Saturday afternoon. Winds
will become westerly behind the frontal passage. Temperatures
have the potential to reach into the 60s on Sunday ahead of the
frontal passage.

High pressure will build into our region behind the cold
frontal passage through midway next week. Winds will start out
of the west but as the high moves over our region, winds will
become more northerly. Temperatures will be mild to slightly
below average through early next week.

Aviation 20z Wednesday through Monday
MVFR ifr CIGS and vis with lingering rain, with freezing rain
and sleet at the colder terminals. Precip ends after midnight
and CIGS vis improve late tonight early Thursday.VFR should
predominate after that until later Friday night, when the next
system brings rain back to the region.

Rain will move into our region with winds becoming southerly on
Saturday. Subvfr conditions are likely.

On Sunday, rain will move through the area by the afternoon.

Winds will be strong aloft with the potential for gusts over 30
knots. Subvfr conditions are possible.

Marine
Marginal SCA will ebb tonight as low pressure developing along
the coast pulls away to the northeast. As another weak front
crosses the region later Thursday into Thursday evening, SCA may
be needed especially over northern waters, less likely to the
south. Light winds are likely Friday and Friday night as high
pressure settles to the north, followed by the approach of the
next system from the southwest.

On Saturday, rain will move through the waters. Winds aloft
will hover near the 10 to 15 knot range. Small craft likely wont
be needed at this time.

Sunday, showers will move through the water Sunday afternoon.

Winds aloft will be strong above 35 knots with the potential to
reach up to 40 knots. This indicates that at least a small craft
advisory will be needed with the potential for a gale warning
on Sunday.

Hydrology
Ultimately, our upcoming flood potential will be determined
after we see exactly how much snow fell on Wednesday and how
much liquid is in that snow. A good melt is ahead for Thursday
and Friday with temperatures above freezing and a decent amount
of sunshine. That will elevate streams and keep them elevated,
ahead of the next system which affects us over the weekend. That
event looks like all rain. Current indications are for between
0.5 inch (low-end) and 2.0 inches (high-end) of rain over the
weekend, on top of remaining snowmelt. If there's still snow on
the ground and if the higher rainfall amounts are realized, this
combination would produce flooding both on small and larger
streams starting late Saturday through possibly early next week.

We will continue to monitor the potential in the coming days.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
