as down the east side of the Blue Ridge (strong enough wind
fields plus downsloping effects are resulting in 40 kt gusts in
the lee of the mountains). The peak gusts of the day likely are
occurring or have occurred (west of I-95) with the immediate
pressure surge behind the front, which is now pressing through
southern Maryland.
As low pressure deepens and slows down near Maine, low level
wind fields will remain strong through the night. Should be
below advisory levels (except perhaps on the ridges), but
elevated gusts will likely continue through the night. Vorticity
rotating around a closed upper low to our north may result in a
few showers across northern areas through this evening. Snow
showers (and perhaps squalls) will be found along the Allegheny
Front, although accumulations should generally remain below
advisory criteria. Cold advection will result in lows in the 30s
to lower 40s.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
The low will remain nearly stationary near the Canadian
Maritimes through Friday while high pressure attempts to build
in from the west. This will keep a tight pressure gradient
across our area, so winds should increase again after sunrise.
Will allow subsequent shifts to determine if additional Wind
Advisories will be needed. Upslope snow showers will begin to
diminish as the upper low pivots away. Otherwise expect a mix of
clouds and sun with much cooler high temperatures in the 40s to
mid 50s.
The gradient winds will continue to weaken Friday evening and
into Saturday as the surface low continues to lift northeastward
away from our region. As winds become light and cooler air
moves into our region, we may need to issue some frost/freeze
headlines for portions of our forecast area Friday night into
Saturday morning. High pressure will be firmly in place over our
region Saturday with winds becoming light. Temperatures will be
continue to be cooler with daytime temps in the 50s and lower
60s. A warm front will lift north of our area late Saturday
night. A lead vort max ahead of the next system may try to
produce a shower or sprinkle across western areas, but most
areas should remain dry. Temperatures will moderate a bit into
the upper 30s to mid 40s.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...
Dry conditions are likely early Sunday with high pressure offshore.
However a potent shortwave diving south out of the Texas Panhandle
will generate a strong area of low pressure over the Gulf of Mexico.
Rain will begin developing Sunday evening as the low tracks
northeastward along the Appalachians. Guidance has been very
consistent with this system in regards to the abundance of rainfall
associated with it. PWAT anamolies based on ensemble guidance
continues to remain 2 to 2.5 standard deviations above normal. Ample
moisture coupled with strong jet dynamics signal periods of heavy
rainfall through the day Monday. Overall, expect a general 1-2
inches of rainfall across the region. In terms of any possible
severe weather poised for Monday, confidence remains low at this
time given low CAPE values and weak mid-level lapse rates. However
given the high shear profile, could be enough to cause locally
damaging winds and perhaps a spin up. The best chance for this to
occur would be late Sunday night through midday Monday as the low's
associated cold front moves through the CWA. On a positive note,
this is a quick moving system and most, if not all, precip will
cease by Monday night.
Weak high pressure will move overhead for Tuesday, giving us a break
in the action. However, the jet stream remains quite active as most
of the continental US remains under a longwave trough. Model guidance
begins to diverge after Tuesday in regards to another shortwave
pulse that could generate another low over the Gulf of Mexico. The
ECMWF develops it just to our southeast, which would set us up
for a similar situation to Monday's system. However the GFS
develops this low further offshore, which would keep our area
drier. In any case, expect the long term pattern to remain
unsettled, with cooler than normal temperatures developing after
Monday through the end of next week.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
Cold front has passed through the terminals. Strongest wind
gusts probably occurred immediately in the wake of the front.
However, strong background westerly winds to around 40 kt will
likely continue until sunset. A few showers or sprinkles may be
near BWI/MTN/MRB through this evening but shouldn't pose any
ceiling/visibility issues. While winds diminish some overnight,
some 20-30 kt gust will remain likely.
Strong westerly winds will continue into Friday with gusts of 25 to
40 knots possible. Winds are expected to slowly taper off
Friday evening and into Saturday. No flight restrictions are
expected Friday and Saturday.
VFR conditions are likely early Sunday before CIG/VSBY restrictions
ensue by Sunday evening as rain develops across the region. IFR/LIFR
conditions are likely Monday with periods of heavy rain and possible
thunderstorms. Low-level wind shear is also of concern given a very
strong wind field aloft. Gusty winds are also likely and even
damaging winds cannot be ruled out at this time. Conditions are
likely to improve by Monday evening as the low quickly moves away
from the terminals.
&&
.MARINE...
Strong west winds are occurring in the wake of a frontal
passage. Gale Warnings remain in effect through the afternoon,
and may need to be extended into the evening for portions of the
waters. Generally SCA winds expected overnight, but will
increase again after sunrise. Portions of the waters may need a
Gale Warning, but am letting subsequent shifts make that
determination. SCA conditions will continue through Friday night
before diminishing Saturday as high pressure builds overhead.
Low pressure will track northeastward Sunday evening into Monday.
Gusty south to southeast winds are likely, with the strongest winds
most likely Sunday night into Monday morning. Periods of heavy rain
and perhaps even a couple thunderstorms are expected. Gusty to
damaging winds are possible in any thunderstorms that develop. A
brief waterspout is possible as well, given a very strong wind field
aloft. Confidence for this to occur is low at this time.
