Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
409 PM EDT SUN JUN 12 2016
.SYNOPSIS...
A dry cold front will continue to shift south over the area
through the rest of the afternoon. High pressure will build over
the area through Monday. A stationary front will develop across
the area Monday night and persists through the middle of the week
before pushing south Thursday.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
As of 2pm, a dry cold front is probably depicted best as the north
side of the cumulus field extending from Petersburg, WV to DC to
Cambridge, MD. Dewpoints quickly drop from the 60s to the 40s
behind the dry line/front. Scattered showers and possible
thunderstorms will continue south of the front, over the central
Shenandoah Valley to lower southern MD waters through the rest of
the afternoon before moving to southern VA. Cold air advection has
capped or lowered temperatures behind the front despite full June
sunshine. Therefore, the daily max temperature records should be
secure (though DCA and BWI were only three degrees below at 2pm).
Northwest winds will continue to gust 35 to 40 mph across the area
this afternoon with a sprawling 996mb surface low over Maine.
Winds will diminish through the evening hours, though gusts are
expected to remain above 20 mph through the nights for all but
sheltered valleys. Minima 50s inland with low 60s nearshore and
40s in the allegheny highlands with dewpoints in the 40s.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/...
High pressure builds to the central Appalachians through Monday.
Decent pressure gradient persists through midday Monday with NWly
gusts around 20 knots through the morning. Maxima generally low
80s with increasing high clouds through the afternoon.
Low pressure persists over the Canadian maritimes through Tuesday
night while low pressure reaches the upper Midwest. A narrow ridge
between aides convergence over the area. POPs Tuesday night
primarily over the NErn half of the CWA for showers. Near normal
temperatures.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
A persistent area of low pressure will stretch across our region
Wednesday through Thursday. A chance of showers and thunderstorms
will exist throughout the period with seasonably warm temperatures
each afternoon and mild temperatures each night.
An upper level disturbance will drop south-southeastward
from the upper Midwest and Great Lakes toward the Tennessee
Valley Thursday night through Friday night. The chance exists for
some rain showers or perhaps a rumble of thunder each period.
However; a ridge of high pressure, building southeastward on
the eastern fringe of the disturbance, could keep most of the
convection in check as it pushes some stable air into the
region from the northeast. Temperatures will become a few degrees
cooler late in the week.
Uncertainty exists in the forecast for next weekend as the latest
GFS/ECMWF have a large retrograding low spiraling just south and
east of the region. This may bring a period of unsettled weather
next weekend but due to the cutoff nature of the low the track and
resultant sensible weather over the area is highly uncertain.
&&
.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
VFR conds through Tuesday. High pressure builds to the west
through Monday. Strong NWly flow to 30 knots rest of the afternoon
with 20 knots overnight. Gusts up to 20 knots continue through Monday
