Synopsis
Arctic high pressure will slide overhead today before migrating
off the mid-atlantic coast tonight. A cold front will near the
ohio valley on Wednesday, stretching into our area Wednesday
night into Thursday as low pressure rides along the boundary.

Another cold front will cross the area on Friday with high
pressure building overhead through the first half of the
weekend.

Near term through tonight
High pressure is settling over the region this morning, with
winds trending lighter and temperatures running very cold in the
teens to single digits. With winds abating earlier this morning,
the wind chill advisory was able to be pulled early across the
higher elevations of the alleghenies.

The high will transit the area today, moving off the mid-
atlantic coast tonight. This will allow for mostly sunny skies
the bulk of today, with an increase in mid to high level clouds
later this afternoon and tonight as warm air advection
increases. Highs today will range in the low to middle 30s. As
the high shifts offshore tonight, southerly flow and warm air
advection will continue to increase, with lows holding in the
20s to near 30 degrees. Hi-res guidance does indicate the
possibility of some light wintry precipitation over the potomac
and allegheny highlands late tonight. Not all guidance favoring
this solution, but we are advertising low end chance pops in
the gridded forecast for the possibility of light freezing rain
and or sleet toward daybreak Wednesday.

Short term Wednesday through Thursday night
Low pressure will near the lower great lakes region on
Wednesday, stretching a cold front into the ohio valley. With
continue warm air advection and increasing moisture, rain will
creep in to the area from the west on Wednesday, as the bulk of
the moisture likely holds off for much of the cwa, outside of
the highlands, until late Wednesday afternoon and evening.

Highs during the day will be unseasonably warm given southerly
flow, ranging from the middle 40s to lower 50s.

Periods of rain, heavy at times, is likely Wednesday night and
into Thursday as a frontal boundary lingers nearby and low
pressure slides across the area. Guidance in fairly good
agreement with rainfall amounts totaling one to one and half
inches by Thursday afternoon, with the focus of the heaviest
rainfall along and east of the blue ridge mountains.

Precipitable water values are also progged to be on the order of
1-1.5" range. Given recent rains, and snow ice melt that will
also occur, flooding is looking increasingly possible along
smaller streams and mainstem rivers through weeks end.

Temperatures will also be quite warm Wednesday night as the low
crosses the area, likely holding in the 40s and 50s.

Temperatures will fall throughout the day on Thursday as the
front moves to our east and the low pulls off the coast. As
temperatures fall, we will see a change over in precipitation
from west to east, with rain snow mix possible west of the blue
ridge Thursday morning, and that transition continuing further
eastward Thursday afternoon and early evening. Outside of the
upslope areas (1-2"), not expecting any accumulation as the
heaviest precipitation will likely be pulling east of the bay by
early afternoon. Drier air on northwest flow will bring an end
to precipitation for all areas outside of continued upslope
snow production Thursday afternoon and evening. Lows Thursday
night will fall back in to the 20s, with teens likely over the
alleghenies.

Long term Friday through Monday
Dry chilly air will lead to below normal temperatures again Friday
and Friday night. A brief and weak cold front will make an effort to
cross the region Friday night into Saturday. A couple of snow
showers in the mountains is all that is expected with this front in
terms of precipitation. A reinforcing installment of arctic air will
follow the front Saturday into Saturday night. With the arctic air
rush, we can't rule out that flurries or a snow squall will reach to
the i-81 corridor or perhaps parts of the metro areas Saturday night.

A weak arctic high will build in Sunday. The next storm system looks
as if it will be arriving from the west and not the south Sunday
night through Monday night. A couple of rain and snow showers are
possible with this approaching storm system along its warm front
Sunday night and Monday, then with the storm and its cold
front Monday night and Tuesday.

Aviation 08z Tuesday through Saturday
Vfr conditions through tonight as high pressure transits the
area and shifts off the coast tonight. Light southerly winds at
10 knots or less expected through tonight, with an increase in
mid to high level clouds.

Vfr conditions likely the first half of Wednesday as a cold
front nears the ohio valley. MVFR CIGS likely return Wednesday
afternoon, with MVFR ifr vis CIGS likely Wednesday night and
into Thursday as the frontal boundary lingers near the terminals
and low pressure passes through the region. Periods of rain,
heavy at times, can be expected Wednesday night and during the
day on Thursday.VFR looks to return to the terminals late in
the day on Thursday, and persisting into Thursday night.

Vfr conditions Friday through Saturday night. Winds northwest 10
knots Friday, becoming light and variable Friday night and Saturday.

Winds becoming southwest 5 to 10 knots Saturday night.

Marine
Sca wind gusts persisting early this morning will abate over
the next few hours as high pressure nudges over the waters. Sub
sca conditions expected today and the first half tonight as the
high transits the area, shifting off the coast tonight. Sca
conditions expected to return late tonight over the main stem of
the chesapeake, extending across all waters during the day on
Wednesday.

A stalled frontal boundary will linger near the waters Wednesday
night into Thursday, as low pressure rides along the boundary,
sca conditions likely under southerly flow and reduced
visiblities in moderate to heavy rainfall. SCA conditions
possible Thursday night as the aforementioned boundary low
exits to the east and the gradient remains tight.

Small craft advisories possible mainstem chesapeake bay Friday. No
marine hazards expected Friday night through Saturday night.

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.
