.SYNOPSIS...
Low pressure will drift toward New England tonight. High
pressure will briefly build in its wake late Sunday through
Monday. Multiple waves of low pressure will approach from the
Gulf Coast Tuesday through Friday.


.NEAR TERM /THROUGH TONIGHT/...
As of mid afternoon, low pressure is located over the Eastern
Shore and will be tracking northeastward toward New England
through tonight. The steadier rain has exited to the northeast,
although some patchy drizzle and fog lingers roughly near and
northeast of the Potomac River. Clouds are breaking up to the
southwest, but some locations will remain cloudy through sunset.
Areas that see sun will warm into the upper 50s to lower 60s,
while cloudy areas may stay in the 40s.

As the low pulls away tonight, weak high pressure will build
from the northwest. Winds will be light and variable with a weak
pressure pattern. While lower clouds may clear out of most of
the area by this evening, some mid level clouds may persist.
This, in addition to a westerly background flow, causes some
uncertainty in the redevelopment of fog and low clouds tonight.
However, many guidance sources indicate this potential, and
with saturated low levels, any fog that does develop may be
dense. Some patchy light drizzle is possible as well, especially
closer to the mountains. Overnight lows will be mild in the
upper 30s to mid 40s.


.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
High pressure at the surface will be over the area on Sunday
while ridging builds aloft. If low clouds or fog develop
overnight, it`s possible this moisture could become trapped
under a subsidence inversion amidst a weak wind field. That will
make the difference between high temperatures in the 50s vs 60s.
Even if low clouds aren`t present, clouds around 4-6kft will
likely outweigh the sun for much of the area.

High pressure will reposition to the north and east Sunday
night into Monday. In response, light easterly flow will develop
at low levels. An increasingly marine air mass will be
transported into the area. As a result, low clouds and/or
drizzle may form Sunday night. These low clouds may potentially
linger through much of the day Monday, especially to the east of
the Blue Ridge. Depending on how thick the cloud cover is,
there could be a wide range of potential temperatures Monday,
with ensemble guidance showing anywhere from the low 50s to just
shy of 70 for highs.

Late Monday into Monday night, convergence and moisture will
increase ahead of an area of low pressure lifting north from the
Carolina coast. Rain is looking increasingly likely Monday
night, especially near and east of the I-95 corridor.


.LONG TERM /TUESDAY THROUGH SATURDAY/...
Little change to previous extended forecast. There is the
potential to encounter some precipitation is nearly every
period.

A low pressure system over eastern North Carolina will move
north along the coast toward our CWA Tuesday through midday
Wednesday. Some rain and perhaps a gusty breeze will accompany
it through the period. Temperatures are expected to be above to
well above normal each day.

As this low pulls away from the East Coast, the next low pressure
system and affiliated trough will make a move into our CWA Wednesday
night through Thursday afternoon. Again, rain chances seem like the
primary precipitation type with this low. It seems to have more
moisture and could produce higher amounts of rain during the
midweek. Temperatures won`t be as warm but should still be above
normal Wednesday night and Thursday.

We could see a break in the rainfall between Thursday night and
Friday afternoon, before system number three makes a run at us
from the southwest. One thing to note is that between the
Wednesday and Thursday system and the one arriving Friday night,
there could be enough clearing, radiational cooling and cold
air advection over our region that we have to watch for a wintry
mix threat on the front side of the third system. Temperatures
as of now should be above normal on Friday.

Sea Level — Job 38:8-11
Who shut in the sea with doors, when it burst forth and issued from the womb; when I made the clouds its garment, and thick darkness its swaddling band; when I fixed My limit for it, and set bars and doors; when I said, ‘This far you may come, but no farther, and here your proud waves must stop!’
