Area Forecast Discussion
National Weather Service Mount Holly NJ
306 AM EDT Wed Apr 8 2020
.SYNOPSIS...
Showers with embedded thunderstorms will track along a frontal
boundary through the overnight hours moving offshore early in
the day today. A strong cold front will traverse the region
Thursday as low pressure rapidly intensifies over coastal New
England and will gradually depart into the maritimes on Friday.
High pressure will build in for most of the weekend. Another low
pressure coming out of the Gulf Coast states will likely affect
the region late Sunday and into Monday.
&&
.NEAR TERM /THROUGH TODAY/...
Showers with embedded thunderstorms will continue to track
across the region through the overnight hours. The MCS is well
developed tracking across western PA this evening and has had a
history of producing strong winds. We've also seen a line of
discrete cells develop out ahead of the main MCS and several
have developed strong updrafts along with indications of large
hail aloft. The line of storms will continue to track through
the region over the next 3-4 hours with the highest chance for
thunderstorms generally across the south and western portion of
the forecast area. Across much of northern and central New
Jersey the lapse rates are weaker and elevated instability progs
are low enough that we'll be looking at more stratiform rain
showers with some occasional lightning strikes. Based on
observed soundings at IAD and OKX, and forecast sounding from
the NAMNest and HRRR we continue to think the severe potential
from storms should be large hail rather than winds as the stable
layer at the surface has prevented most of the stronger winds
from mixing down.
The line of showers should pass through the region by daybreak
this morning and we'll see a warm front surge north bringing
temps well above April normals into the upper 60s to low 70s
across east central PA, south and central NJ and DelMarVa. As
temps warm we'll see widespread convective instability develop
across the region with the potential for some isolated
thunderstorms to develop. The forcing is weak however so any
storms that do develop will likely just pulse storms will little
forward propagation anticipated.
&&
.SHORT TERM /TONIGHT THROUGH 6 PM THURSDAY/...
An active day of weather is likely Thursday. Synoptically, a
classic evolution as a strong shortwave dives into the Great
Lakes. The subtropical and polar jets look to phase just south
of our region, with a strong (160 kt+) jet max developing. Just
downstream the shortwave, surface low pressure will be tracking
out of Canada and into New England. Over the course of the day
Thursday, the shortwave will begin to pivot more negative in
tilt. Meanwhile, the low pressure will find itself in the
divergent left exit region of the strong jet max to our south,
and will also feel increasing baroclinic influence as it
approaches the Gulf of Maine. The result will be a period of
rapid deepening of the low on Thursday as its center jumps
towards the Maine coast, with its central pressure dropping
below 970mb by Thursday evening.
In terms of sensible weather, two primary and somewhat related
concerns for Thursday. A strong cold front associated with the
strengthening low will move through during the day, likely from late
morning through mid afternoon. Ahead of it, there is potential for
convection. This is a conditional threat as there is uncertainty as
to destabilization. Trends in guidance with the front are
generally faster, which would limit daytime heating and
instability and help keep convection more limited and/or
elevated. However, if we do develop some surface based
instability, severe winds would be a concern given very strong
forcing and impressive wind profiles. The second concern on
Thursday will be the potential for a period of strong synoptic
winds immediately behind the front. We should quickly mix out
once the front passes, and low level winds remain particularly
elevated for a couple of hours. BUFKIT profiles suggest the
potential for a period of 40 to 50 mph wind gusts, before winds
likely weaken a little, at least temporarily, into the evening
and overnight hours. Overnight, strong cold advection will be
ongoing, but the breezy conditions will keep the lows near or
only a little below average, though it will feel colder.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Overview...
An active pattern is poised to continue over the next several days
and likely beyond as persistent troughing over the Great Lakes fuels
an active storm track in the East. Definitely a much different type
of pattern than we've seen most of the past few months as a steady
supply of cold Canadian air gets ushered into the northern US.
Combined with a growing supply of very warm, moist air over the Gulf
region and a strong subtropical jet, this is a recipe for frequent
storminess in the days and potentially couple of weeks ahead. Two
synoptic storm systems are likely to impact us this period, one on
Thursday and the other early next week, but most of the days this
period will feature some weather concerns in one way or another. For
this forecast, the bulk of the attention was placed on the Thursday-
Friday period, as the weekend appears relatively quiet and the
potential storm system early next week is a little too far out to
pay much attention especially given concerns in the nearer future.
Dailies...
Friday-Friday night... For Friday, attention will again be on
the winds as intense low pressure moves out of the Gulf of Maine
and into the Canadian maritimes. A tight pressure gradient will
be in place, and guidance agrees on deep mixing during the day,
likely to near 700mb. Winds at 850mb and above look to be in
the 30 to 45 kt range, and much of that is likely to be brought
down to the surface in gusts. GFS BUFKIT profiles would support
advisory level winds, while the NAM would likely keep us just
below. Either way, it will be a windy day and likely on the edge
of Wind Advisory thresholds. Boundary layer RH values remain
fairly high on Friday, and this will help some surface based
instability develop. In the winter months this is the type of
day we'd watch for snow squall potential. We're lacking much of
a trigger mechanism, but a rain or snow shower is possible
Friday especially up north towards the Poconos. Highs on Friday
only in the low 50s for most with some 40s to the north as
unseasonably cold air is advected in behind Thursday's front. A
chilly night is likely as well, but winds should remain elevated
enough to prevent a freefall in temperatures and also limit the
frost potential.
Saturday-Sunday... A general lull in active weather for the weekend.
High pressure moving out of the Midwest will be centered to our
south on Saturday then offshore by Sunday. Could have some fire
weather concerns on Saturday pending what the fuel moisture looks
like as the winds, while much lighter than Friday, will still be a
little breezy and RH values drop a little more. A warming trend is
likely over the weekend following the Friday cooldown. Depending on
the timing of the next system, could have some showers by Sunday
afternoon especially to the south, but think most of the day will be
dry.
Sunday night-Tuesday... Our next weather system arrives. As
mentioned, did not spend too much time on this period given more
pressing shorter term concerns. But the general idea looks to be low
pressure lifting out of the Gulf Coast region as a trough ejects out
of the Plains and ridging builds along the East Coast. With roots in
the Gulf of Mexico, this may be a moisture laden system with
potential threats of heavy rain and gusty winds, but we'll have
several days to watch its evolution.
&&
.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
Tonight...VFR with periods of IFR in showers with embedded
thunderstorms. Prevailing winds will be southwest generally 10
knots or less. High confidence in the wind and the occurrence
of showers.
Wednesday...Ceilings should quickly improve from MVFR to VFR.
Northwest wind around 10 knots. Medium confidence.
Outlook...
Wednesday night-Thursday... Deteriorating conditions expected
as VFR prevails initially before becoming widespread MVFR and
potentially IFR should develop later Wednesday night. Continued
MVFR/IFR into Thursday morning. A band of moderate to heavy rain
with embedded thunderstorms will move through from west to east
between mid-morning and mid- afternoon. Behind this,
improvement to VFR is possible Thursday afternoon and evening.
Light and variable winds Wednesday night will become southerly
Thursday morning. Winds will shift to southwest then west-
northwest as the area of rain moves through. As this happens,
speeds will abruptly increase with gusts of 35 to 40 kt possible
Thursday afternoon. Low confidence in flight conditions
Wednesday night. Moderate confidence for overall trends on
Thursday.
Thursday night... Mainly VFR. Westerly winds 10 to 15 kt with gusts
to 25 kt. High confidence.
Friday-Friday night... Mainly VFR, but MVFR possible especially
towards RDG and ABE during the day Friday. West-northwest winds of
15 to 25 kt with gusts as high as 40 kt Friday afternoon. Winds
gradually diminishing overnight. High confidence.
Saturday-Saturday night... VFR. West-northwest winds 10 to 15 kt
with gusts to 20 kt, becoming southwest in the evening then light
and variable overnight. High confidence.
&&
.MARINE...
A warm front is forecast to lift over the coastal waters of Delaware
and New Jersey for tonight. Weak low pressure is expected to pass
off our coast on Wednesday morning, pulling the frontal boundary
back to the south.
Wind speeds and wave heights are anticipated to remain below the
Small Craft Advisory criteria.
Outlook...
Wednesday night... Sub-SCA conditions expected. Winds northeast
shifting to southeast at around 10 kt. Seas 2 to 4 ft.
Thursday-Thursday night... Initially sub-SCA conditions. However, a
sharp increase in winds is likely during the late morning or early
afternoon as winds shift from southwest to northwest with a frontal
passage. Gale force winds are possible Thursday afternoon.
Overnight, conditions will more likely diminish slightly to SCA
levels, though west-northwest winds could still gust to 30 kt and
cannot rule out gale conditions. Seas mainly 3 to 5 ft.
Friday... Westerly gales expected. Wind gusts to 40 kt or slightly
higher are likely. Seas 4 to 6 ft.
Friday night-Saturday... Gradual improvement in conditions expected.
Winds should drop below gale force early Friday night, and may drop
below SCA levels on Saturday though will still likely be gusting 20
to 25 kt out of the west-northwest. Seas 3 to 5 ft Friday night
diminishing to 2 to 3 ft on Saturday.
&&
.TIDES/COASTAL FLOODING...
A coastal flood advisory has been issued for the southern shores
of the Raritan Bay, the New Jersey shore, and the Delaware
Beaches for the high tide cycle on Wednesday evening.
Astronomical high tides will be running high for the next few days
associated with the full moon on April 7. We don't have much onshore
flow through the next few days, but given the current astronomical
high tides, even weak onshore flow could produce minor coastal
flooding. At this point, we are expecting spotty minor flooding for
most high tide cycles until we get to Wednesday evening. For the
Wednesday evening/night high tide, widespread minor flooding
is expected for the Atlantic oceanfront.
On the Delaware Bay and tidal portions of the Delaware River,
there could be spotty minor tidal flooding for the next few high
tide cycles, but the chance for widespread minor flooding is
low.
At this point, tidal flooding is not expected along the northeastern
Chesapeake Bay.
