Synopsis
A cold front will continue to move south of the area tonight.

Canadian high pressure will dominate in its wake through the
middle portion of the work week. This high will shift offshore
Wednesday night as a frontal boundary lingers near the mid
atlantic to finish out the week.

Near term through Tuesday
Clearing tonight east of the mtns as cdfnt pushes south. There
will be some upslope stratocumulus over the appalachians, but
other than that clear and cooler tonight. Winds will pick up
overnight some in eastern areas due to a pressure surge. Turning
breezy into tomorrow morning.

Short term Tuesday night through Wednesday night
High pressure will build down of the mid atlantic from the
great lakes Tuesday through Wednesday. Gusty northwest winds on
Tuesday will yield much cooler temperatures in the low to middle
70s area wide, moderating slightly on Wednesday but still
holding in the 70s. The strong and complex system impacting the
southern central plains the next couple of days will lift
northward into the upper midwest late Wednesday and Wednesday
night. This will lift a warm front toward our region Wednesday
night as the high shifts off the coast. This will likely bring
an increase in cloud cover Wednesday night, as well as
increasing shower chances by early Thursday morning, mainly west
of the blue ridge.

Long term Thursday through Monday
Upper level ridging will remain centered over the southeastern
united states through at least Saturday. A warm front likely will be
north of the area on Thursday. Some diurnal convection will be
possible due to increasing warmth and humidity, along with a
potential disturbance rounding the ridge and a lee pressure trough.

Recent guidance trends suggest a stronger shortwave will drive low
pressure into new england Thursday night into Friday, which will
send a cold front southward through the area... Another potential
focus for precipitation.

High pressure will briefly build in Friday night with the upper
ridge expanding back north. Temperatures will return to normal as
long as we're on the north side of the front. The next low pressure
system will be moving through the northern plains, which will
eventually force the warm front back northward later in the weekend.

As the low moves toward eastern canada, the front will make a push
back to the south, though how far it gets will depend on the
strength of the ridge. Chance for convection will depend on the
positioning of the fronts from Saturday through Monday, thus pops
will be kept low at this time.

Aviation 01z Tuesday through Saturday
The front will push to the south and east of the terminals this
evening, with west northwest winds taking hold overnight.

Canadian high pressure will build over the terminals Tuesday
through Wednesday, with gusty northwest winds on Tuesday
slacking and becoming light through Wednesday night. No threat
for precipitation or subVFR conditions Tuesday and Wednesday.

Vfr conditions will prevail Thursday through Saturday but brief
flight restrictions could be possible as showers and thunderstorms
develop along a wavering frontal boundary.

Marine
After a bit of a lull in winds in the wake of the frontal
passage, the gradient is expected to tighten Tuesday morning,
thus SCA conditions expected once again. As high pressure shifts
over the region Tuesday night through Wednesday night, light
winds will prevail with no threat of gusty showers storms.

A warm front will lift north Thursday and return south on Friday as
a cold front. If current model projections hold, SCA conditions
could occur with northwest winds on Friday. High pressure will bring
lighter winds Saturday.

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.
