705 am edt Wed oct 16 2019

Synopsis
Periods of rain Wednesday ahead of a strong cold front. Gusty
winds are expected behind the front Wednesday night into
Thursday. High pressure builds in for the end of the week
resulting in cool and dry weather.

Near term until 8 am this morning
As of 600 am edt Wednesday...

rain started moving into the southwest portions of the cwa
around 9z. Adjusted the near term pops a little further east.

Rainfall amounts through 12z will be light across the southwest,
likely a trace to about a tenth of an inch. Surface obs and
satellite confirm much of the region is now overcast as mid and
high clouds have spread over the area. Some patchy fog can be
found in areas that saw a little bit more clearing earlier this
morning, mainly richmond and areas northwest, as well as
portions of the md eastern shore.

Short term 8 am this morning through Friday
As of 345 am edt Wednesday...

some much needed rain will spread across the entire region today.

The forecast challenge today will be in the amount of rain that
falls across the area. A cold front associated with a low pressure
centered over the great lakes will approach from the west today.

This system will interact with another low expected to develop near
or just off our coast this morning. Latest hi-res models show that
rain should start to overspread the region from SW to NE beginning
after 09z. Moderate to heavy rain is expected at times from late
morning through the afternoon, before tapering off near 00z tonight.

Region wide QPF amounts will be in the 0.5-1.0 inch range, with
localized higher amounts. SPC has our region outlooked for general
thunder today. Highest chances for that will be across the eastern
half of the forecast area as instability increases modestly during
the afternoon and early evening hours. Mostly cloudy skies and
periods of rain will keep temps on the cooler side today, with mid
to upper 60s over the western half of the CWA and lower 70s near the
coast.

After the cold front crosses the area tonight, wnw winds will become
gusty as drier cooler air begins to filter into the region.

Wind gusts by late Thursday morning will be 25-35 mph and that
will continue through much of the day before relaxing to 10-20
mph by late Thursday into early Friday. Low temps will drop to
the low to mid 40s for most on Thursday and Friday with near 50
degrees close to the coast. Wouldn't be surprised to see some
upper 30s across the far nw. High temps will be cool and
pleasant reaching the low to mid 60s both days.

Long term Friday night through Tuesday
As of 230 pm edt Tuesday...

sfc hi pres moves out off the coast Fri night through sat
resulting in dry near seasonable wx. Return flow behind the high
once its off the coast Sun through Mon will bring an increase
in moisture (and pops) from the SW ahead of lo pres tracking
through the midwest - initially inland late Sun sun night... Then
all areas mon. A cold front is expected to cross the region tue
w additional ra chcs.

Lows Fri night 40-45f inland to the l50s at the (immediate)
coast. Highs Sat in the u60s-l70s. Lows Sat night in the u40s
inland to the l-m50s at the coast. Highs Sun in the l-m70s. Lows
sun night in the m-u50s... Except l60s at the coast. Highs mon
from the l70s N to the u70s far se. Highs Tue in the u60s NW to
the u70s.

Aviation 11z Wednesday through Sunday
As of 700 am edt Wednesday...

rain will overspread the region this morning with the heaviest rain
expected late morning through the afternoon hours before tapering
off this evening. Expect periods of MVFR ifr ceilings and visbys,
especially during times of moderate to heavy rain. There is a slight
chance of thunder across the eastern portion of the forecast area
today, but chances are too low to mention in the tafs. All locations
should return toVFR after 00z tonight. Winds will be S SW ahead of
the front turning to the W NW during the afternoon. Winds will
become quite gusty behind the front, with gusts of 15-25kts and
perhaps 30kts at ksby. Strong gusts will continue through Thursday
before diminishing overnight into Friday morning.VFR conditions are
expected Thursday through Saturday. On Sunday a storm system
originating in the gulf is forecast to ride up the carolina coast.

Depending on the track of this system, some showers could affect the
region which may result in periods of subVFR conditions.

Marine
As of 330 am edt Wednesday...

sub-sca conditions prevail early this morning with a SE wind
around 10 kt on avg and seas of 2-3 ft, bay waves 1-2 ft.

Conditions will slowly worsen later today and then really
deteriorate in the wake of a strong cold frontal passage this
evening. Only real change to the forecast was to convert the
gale watch for the coastal waters N of CAPE charles to a gale
warning and to upgrade the northern bay zone (smith pt to
windmill pt) to a gale warning. These areas are expected to see
a prolonged period of gusts to at least 35-40 kt this evening
into early Thu am (potentially 40-45kt coastal waters N of
parramore island).

Elsewhere, strong scas (due to winds) are expected starting
this evening through Thu night. Do anticipate a brief period of
higher gusts this evening W the frontal passage (about 2 hrs
worth of occasional gusts to 35-40 kt). May need to issue a
short fused smw to cover this but felt that a gale warning would
be too long for short term event. Seas will build to 5-7 ft n
and 4-6 ft s, while waves in the bay build to 3-5 ft, and 2-3 ft
waves in the rivers. The current forecast has winds remaining
aoa SCA thresholds for bay and coast through ~12z fri. Sub-sca
conditions return by late fri, as high pressure settles over the
waters.

Tides coastal flooding
As of 330 am edt Wednesday...

seeing some slowly increasing tidal anomalies into the bay and
will let current coastal flood statement continue over
dorchester co md for the next few hrs. Will then likely be
issuing another coastal flood statement and or advisory across
much of the upper bay for the upcoming high tide cycle this
aftn due to a continued increase in tidal departures as the sse
winds increase and with cbofs forecast for a dominant flood tide
through the aftn helping trap water into the bay. Then, in the
wake of the cold front tonight, strong wnw flow will lead to a
strong ebb tide for ~24 hrs through thu. This will lead to
significant drops in water levels across the bay. Does not
appear to be enough to lead to low water advisories given the
initial elevated water levels.
