...COASTAL FLOOD ADVISORY IN EFFECT FROM 10 AM MONDAY TO 5 PM EST
TUESDAY...
* WHAT...Up to one foot of inundation above ground level
expected in low-lying areas near shorelines and tidal
waterways.
* WHERE...Cumberland.
* WHEN...From 10 AM Monday to 5 PM EST Tuesday.
* IMPACTS...At this level, flooding begins on the most
vulnerable roads in coastal and bayside communities, and along
inland tidal waterways. Some partial or full road closures are
possible.
* ADDITIONAL DETAILS...The wind will be blowing offshore, so tidal
flooding should be less than on the opposite shore of Delaware
Bay. There remains some uncertainty with regards to the degree
of tidal flooding expected however.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Coastal Flood Advisory means that minor tidal flooding is
expected. Minor tidal flooding often results in some road
closures. Usually, the most vulnerable roadways will flood.
Do not leave your vehicle at a location that is prone to tidal
flooding. Do not drive your vehicle through flood waters. The
water may be deeper than you think it is. You will be putting
yourself in danger and your vehicle may be damaged, leading to
costly repairs.

water.weather.gov/ahps for additional water level and flood
impact information for your local tide gauge.

expected in low-lying areas near shorelines and tidal
waterways.
* WHERE...Cumberland.
* WHEN...From 10 AM this morning to 5 PM EST Tuesday.
* IMPACTS...At this level, flooding begins on the most
vulnerable roads in coastal and bayside communities, and along
inland tidal waterways. Some partial or full road closures are
possible.
* ADDITIONAL DETAILS...The wind will be blowing offshore, so
tidal flooding should be less than on the opposite shore of
Delaware Bay. There remains some uncertainty with regards to
the degree of tidal flooding expected however.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Coastal Flood Advisory means that minor tidal flooding is
expected. Minor tidal flooding often results in some road
closures. Usually, the most vulnerable roadways will flood.
Do not leave your vehicle at a location that is prone to tidal
flooding. Do not drive your vehicle through flood waters. The
water may be deeper than you think it is. You will be putting
yourself in danger and your vehicle may be damaged, leading to
costly repairs.

Area forecast discussion, Jan 31, 12:38 PM EST, 1 hour 48 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1238 PM EST Sun Jan 31 2021
.SYNOPSIS...
Low pressure will move through the Ohio Valley today. A secondary
low develops along the southeastern coast tonight and tracks up into
the Mid-Atlantic. This low will slowly move northeastward through
Tuesday and into the Canadian Maritimes on Wednesday. High pressure
will build in from the west through Thursday. A cold front will
cross the region late Friday night into Saturday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
10 AM Update: Adjusted PoPs to account for the latest radar
trends and observations across Delmarva. Light to moderate snow
has begun across much of the peninsula as of the past hour or
so. This will continue spreading slowly northeastward into the
afternoon toward the Philly metro, Berks County, and up the New
Jersey shore.
Also with this update, I adjusted forecast weather type and
snow totals based on the latest 12Z guidance trickling in. This
was mainly to account for more sleet mixing in late tonight and
early Monday across extreme southeastern Pennsylvania and
Wilmington areas, which nudged totals down a smidge. This same
guidance continues to indicate that the best chance for
frontogenetic forcing will be generally north and northeast of
the Philly metro area, generally from the Lehigh Valley east and
north toward northern New Jersey (north of I-195). Totals were
nudged up slightly in these areas.
Previous discussion...
Cold and dry over the region as the base of high pressure over
eastern Canada is sagging into northern New York and northern
New England, and another area of high pressure is off the Mid-
Atlantic coast. The center of low pressure is over the Midwest
and lower Great Lakes and will drift east today. Meanwhile, a
secondary low will begin to form over the Southeast U.S. as the
base of a deep upper trough digs through the Gulf Coast states.
Surface dew points are climbing into the teens and low 20s
throughout, and will continue to rise through the day as north
to northeast winds back to the east.
Overrunning precip will develop out ahead of a developing warm
front as that secondary low forms. However, it will take quite
some time for precip to reach the ground for most of the region
given how cold and dry it is. So for most of the day, any precip
that forms will fall as snow, and areas impacted will mainly be
Delmarva, southern New Jersey, and the Delaware Valley,
including Philadelphia. Enough warm air should lift into
southern Delaware late in the afternoon to allow snow to mix
with and change to rain.
In general, 2-3 inches of snow will fall over the western suburbs of
Philadelphia, Delmarva, and extreme southern New Jersey, and 1-2
inches up through Berks county, Philadelphia, and I-195 in New
Jersey.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
A complex and prolonged storm system remains on track to impact the
region through Tuesday.
The secondary low that will begin to form over the Mid-Atlantic on
Sunday will lift north along the coast tonight, and will be just off
the Delmarva Peninsula by daybreak Monday. The original primary low
that was over the Great Lakes continues to track east tonight, and
will merge with the secondary low Monday morning, and menders off
the New Jersey coast for a prolonged period of time until a closed
upper low passes over the region Monday night, and slowly departs on
Tuesday.
The 00Z suite of model guidance continues to bring the surface low a
bit farther west and a bit farther to the north. As a result, latest
trends are for the heaviest axis of precip to be across the northern
zones, and with strong banding across those northern zones as strong
shortwave energy lifts into the region. In addition, some mid-level
warm air with 925-850 mb temps to 0C lifts north through Delmarva,
along the I-95 corridor to Philadelphia, and up to I-195 in New
Jersey late tonight and into Monday morning. In these areas, snow
will mix with or change to sleet, resulting in lowered snow amounts
that might otherwise fall. Precip changes to plain rain in most of
Delaware and the eastern shores of Maryland and extreme southern New
Jersey late tonight through Monday. The rain/snow line should get as
far north and west as the I-95 corridor, and north and west of the I-
95 corridor, precip will remain all snow. Snow will be heavy at
times across the southern Poconos and northern New Jersey during the
day Monday and into Monday evening due to strong banding.
Went ahead and increased QPF, and as a result, snow fall, across the
northern half of the forecast area, and also lowered QPF and snow
amounts across the far southern half as some dry slotting may lift
into Delmarva.
Strong low level jet of 65-75 kt at 925-850 mb lifts along the New
Jersey coast, and with a tight easterly pressure gradient forming
between low pressure off the New Jersey coast and high pressure over
the Northeast, gusty winds of 25-35 mph will develop across much of
the region, and wind gusts as high as 50 mph along the New Jersey
coast.
In terms of snowfall, 12-18 inches of snow will fall across the
southern Poconos, Lehigh Valley, and northern New Jersey, and 8-12
inches along the I-95 corridor into the western suburbs of
Philadelphia, and 2-4 inches elsewhere tonight through Monday, and
another 1-3 inches of snow along and east of I-95 and 3-5 inches
north and west of I-95 Monday night through Tuesday.
A prolonged Winter Storm Warning remains in effect for the entire
duration of the storm, though additional snowfall on Tuesday will be
minimal as low pressure slowly departs.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Tuesday night through Wednesday night...The stubborn closed upper
low starts to finally move to the east late Tuesday night into
Wednesday, eventually moving into the Canadian Maritimes Wednesday
night. With the surface low pulling away as well, we should see an
end to the precipitation Tuesday evening, with any lingering stuff
being right along the coastal plain of New Jersey. The winds will
remain up through the night and through much of Wednesday as the
pressure gradient is pretty tight due to the departing surface low
and high pressure pushing in from the west. With the right gradient,
expect winds to gust around 25 to 35 mph through the day on
Wednesday but they should taper off as we head towards the evening
as the gradient finally starts to weaken some. Cold air will remain
in the northwest flow so expect a cold night Tuesday night with a
cold day to follow on Wednesday. While we will have ample snow cover
across much of the region, with the winds remaining up overnight and
considerable cloud cover across the region do not anticipate a good
radiational cooling night so kept minimum temps from really dropping
off. Expect overnight lows to be in the teens to mid 20s across our
forecast area with some upper 20s along the immediate coast. Daytime
highs on Wednesday will be cold and remain in the 30s with some mid
to upper 20s across the higher elevations of the southern Poconos
and northwest New Jersey. Expect Wednesday night to be colder due to
less wind, clearing skies, and plenty of snow on the ground. Might
not be cold enough in the current forecast as we tend to bottom out
more than the guidance indicates. Lows will range from the teens to
mid 20s across the region Wednesday night, though would not be
surprised to see them fall into the lower 10s to low 20s due to the
reasons previously mentioned.
Thursday...we finally come out of the grip of the upper low and see
some slight ridging across the Mid-Atlantic on Thursday. Some
warming aloft will start to take place and the airmass will start to
modify. With less wind it won't feel nearly as cold as on Wednesday
with highs reaching into the 30s to lower 40s. However, with a more
south to southwest flow developing by Thursday evening as a warm
front lifts into the region, we will see an increase in low level
moisture. With plenty of snow still expected to be around there is
the potential for some fog to develop Thursday night.
Friday through Saturday...Low pressure will move into the Great
Lakes region and into Canada on Friday. The associated cold front
will move through our forecast area late Friday night into Saturday.
The front appears to stall or slow down as it crosses through our
area with the potential for additional lows to develop along the
boundary. This will keep us in unsettled weather pattern as we go
into the weekend with the chance for rain or snow. Temperatures do
continue to warm on Friday (which may be the warmest day of the
week) with highs reaching into the 40s to lower 50s but as the front
approaches and cloud cover increases we may not see much more
warming than that occur for Saturday, with the highs generally a few
degrees cooler than that day before. As of now the weekend looks to
be messy but some solutions do show a dry period on Saturday before
the next potential system approaches later in the weekend.

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
This afternoon...VFR ceilings lowering to MVFR and IFR. Visibilities
will quickly drop to IFR and LIFR in snow, with even periods of
heavier snow. East to east-northeast winds increasing to 10-15
knots. Moderate confidence.
Tonight...IFR ceilings overall. IFR/LIFR visibilities this evening
should improve some from RDG to TTN south and east overnight as the
snow mixes with or changes to sleet, with even a change to rain at
MIV and ACY. Northeasterly winds 15-20 knots with gusts 20-30 knots,
with the strongest winds overnight. Low confidence regarding timing
of mixed precipitation/change to rain and how far inland this gets.
ABE expected to remain all snow however.
Monday...IFR ceilings with varying visibilities as precipitation
continues, some of which will be on the heavier side (potential for
1+ inches per hour snowfall rates from around the PHL area northward
at times). The visibilities however should improve some near PHL to
the south and east where a mix occurs in the morning before changing
back to snow. Rain at MIV and ACY should result in MVFR to IFR
visibilities with even a lull in the precipitation during the
morning, then the rain may change to snow in the afternoon.
Northeast winds 15-25 knots with gusts to 35 knots with the
strongest winds closer to the coast, then the winds should turn more
from the north at night. Low confidence on timing of precipitation
type changes and intensity.
Outlook...
Tuesday...IFR ceilings should improve some through the day as snow
comes to an end. North to north-northwest winds 10-20 knots with
gusts to 25 knots. Moderate confidence.
Wednesday...VFR. Northwest winds 15-20 knots with gusts up to 30
knots, dropping off to around 10 knots at night. Moderate confidence.
Thursday...VFR. West winds 5-10 knots, becoming light southwest late
afternoon. Moderate confidence.
Friday...Sub-VFR conditions possible with a chance of rain.
Southwest winds near 10 knots. Moderate confidence.
&&
.MARINE...
Winds and seas will ramp up through the day. Gales develop on
all waters by this evening, and then from late tonight through

.TIDES/COASTAL FLOODING...
A coastal low will meander just offshore the NJ coast this Monday
into Tuesday and strong onshore flow is expected develop tonight and
continue through at least Monday night, before potentially acquiring
a more offshore component on Tuesday. Fairly widespread moderate
tidal flooding therefore looks likely over the NJ/DE coasts and
backbays for at least the Monday morning and evening high tides,
with some potential for flooding persisting into the Tuesday AM high
tide (but this is less certain given that the flow will be backing).
Consequently converted the Coastal Flood Watches to Warnings for the
NJ/DE coasts with this package.
There is also the potential for minor-to moderate tidal flooding
over portions of Delaware Bay, however confidence is a bit too low
at this time (and there is still technically 24 hours to the first
high tide cycle of interest) to upgrade. Therefore will retain the
watch there and the next shift can decide if it should be converted
to a warning or advisory.
