The local office's own words before this gale watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this gale watch went out at Feb 11, 11:58 AM EST, 3 hours 49 minutes earlier.
Area forecast discussion, Feb 11, 11:58 AM EST, 3 hours 49 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1158 AM EST Mon Feb 11 2019
.SYNOPSIS...
Surface ridging related to arctic high pressure across eastern
Canada will persist across the forecast area through Monday as a
weak system pushes offshore. A stronger area of low pressure will
move into the Great Lakes region by Tuesday with a cold front
crossing the area Tuesday night. Low pressure moves northeast into
New England Wednesday then high pressure builds into the region
Thursday. Another low pressure system moves across the Great Lakes
Thursday night into Friday pushing a cold front through the forecast
area late Friday. Weak high pressure will settle into the region for
the weekend.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Will cancel the Winter Weather Advisory that was set to expire
at noon for the tier of counties in central Delmarva and Cape
May county, NJ. Temperatures continue to rise to and above
freezing, and precipitation is becoming light.
Otherwise, additional precip north of the I-95 corridor to
around I-195 will be light. Winter Weather Advisories currently
in effect are mainly for tonight through 1 pm Tuesday. Despite a
lull in precipitation that may last much of the day (especially
on the northern fringe of the advisory), the slippery
conditions present this morning and the potential for more snow
(followed by mixed precipitation by Tuesday morning) suggests
having the advisory expire and following it with another
advisory later may be rather confusing. The bottom line is that
societal impacts from this morning's event will likely continue
to some degree through the time in which more mixed
precipitation occurs tonight and Tuesday.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/...
This is one of the most complicated forecasts of my admittedly
short career, largely owing to logistics, but lack of physical
understanding regarding what will transpire tonight through
tomorrow night is not far behind. We start with
watch/warning/advisory decisions this morning:
(1) Based on collaboration with CTP, BGM, and OKX, we will
continue the winter storm watch as is for Sussex (NJ), Carbon,
and Monroe Counties. This is based on remaining uncertainty with
snow and ice amounts Tuesday and Tuesday night.
(2) Berks, western Montgomery, upper Bucks, and Lehigh Counties
will be in a winter weather advisory from this evening through
early Tuesday evening based on expected onset of wintry
precipitation tonight and transition to mostly rain by Tuesday
evening.
(3) Hunterdon, Somerset, Middlesex, Monmouth, and Mercer
Counties will be in a winter weather advisory from midnight
tonight to early Tuesday evening.
(4) Northampton, Warren, and Morris Counties will be in a winter
weather advisory from midnight tonight to 1 am Wednesday.
(2)-(4) are based on the general onset timing and precipitation
transition of the latest NAM, NAM Nest, and hi-res simulations.
Forecast was based largely on a consensus blend of the coarser
and hi-res 00z/06z models, though additional weight was provided
to the NAM/NAM Nest, owing to its preferred evolution of the
low-level thermal profiles (and its generally good performance
in warm-advection events like the upcoming one).
In general, the overall thinking with precipitation Monday night
through Tuesday night has not changed considerably.
Unfortunately, this means that a large amount of uncertainty
remains, primarily with timing the changeovers from snow to
sleet to freezing rain. The general idea is for snow to spread
northeastward into southeast PA and adjacent portions of
southern New Jersey during the evening, followed by central
portions of New Jersey and eastern PA by or after midnight. As
strong advection continues during this period, a warm nose will
increasingly lead to a transition to sleet and/or freezing rain.
This looks to mainly occur late tonight and Tuesday morning,
generally near/north of the I-76 corridor (precipitation mostly
rain to the south). Mixed precipitation will spread rapidly
northward during the morning hours, and may linger through at
least early afternoon near and especially west of the
Philadelphia metro area. Eventually, warmer air will surge
sufficiently northward to scour the cold air south of the
I-276/I-195 corridors during the afternoon (at least, that is
what is forecast), but the cold air may prove to stick around
much of the day in the Lehigh Valley and northern New Jersey.
There are two main uncertainties to address, should the timing
above be in the ballpark. (1) How much of the precipitation
occurs as snow versus sleet versus freezing rain? (2) Are the
models handling the lingering surface cold air adequately? My
inclination is that snow accumulations may be hindered by
residual dry air from a stubborn surface high to the
north/northeast. However, once the precipitation gets going,
large-scale lift will be strong, so the snow may become moderate
to heavy at times before transition to a mix. The sleet signal
may also be overdone given the strength of the warm advection
aloft. The warm nose may become quite pronounced, especially if
cold air damming is as strong as (say) the NAM suggests. This
certainly makes me worry about icing potential, especially in
the far north (generally near and north of I-80). Though
considerable uncertainty remains with relative amounts of each
precipitation type, the combined effects of snow, sleet, and
freezing rain may be sufficient to produce warning-like impacts
despite no individual type meeting warning criteria. As such,
the winter storm watch remains in effect and it is possible
adjoining counties may be upgraded from the current advisory to
a warning in later forecasts.
Another concern is heavy rain in central/southern portions of
the CWA, though models have trended somewhat downward in this
regard. Some instances of flooding may occur, but this is a
secondary concern to the winter weather potential.
Precipitation winds down quickly Tuesday night as the associated
low(s) move northeastward. Lingering snow showers may continue
in the Poconos and vicinity through or past daybreak Wednesday.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Few changes made to the long-term forecast. Main adjustments
were to increase winds on Wednesday and to lower temperatures
somewhat Wednesday and Wednesday night. Most of the previous
discussion follows...
Wednesday...The surface low lifts pretty quickly to the northeast
through the day on Wednesday. Overall, expect improving conditions
across our forecast area but some lingering showers may remain,
mainly across the southern Poconos, Lehigh Valley, and portions of
northwest New Jersey where the strong northwest flow aloft may drag
enough moisture and precip down from the Great Lakes. Bigger
concern is wind potential, with BUFKIT soundings showing
potential for 35-45 mph gusts. With potential icing the day
before in the northern/central CWA, these winds may be quite
impactful.
Wednesday night through Thursday...High pressure builds across the
southeast US and ridges up into the Mid-Atlantic. Relatively clear
conditions expected Wednesday night which will set up a decent
radiational cooling scenario. However, with winds remaining up as
opposed to going calm, it won't cool as much as it potentially could
and lows will only drop into the 20s. If winds go light overnight
there is the potential for temps to drop down into the teens. Warmer
air will stream northward on Thursday in a more west to southwest
flow and we should get back to closer to normal temperatures. Highs
on Thursday will rise into the 40s across most of the region with
some upper 30s across the higher elevations and lower 50s across
Delmarva.
The high will shift offshore and the east of our area Thursday
night. Increasing cloud cover in advance of the next system combined
with the southerly flow will keep overnight lows warmer and in the
upper 20s to mid 30s across the forecast area. Meanwhile, a low
pressure system will track across the plains states this week and
into the Ohio Valley by Friday.
Friday through Saturday...The surface low will push eastward through
Friday, crossing to the north of the region late Friday into
Saturday. As the low tracks into New York, the trailing cold front
will approach our area. Another low may form along the front as the
front crosses our area on Saturday. Warm air will surge across the
region ahead of the cold front so expect mainly plain rain to fall
across the forecast area as temperatures will rise into the 50s
across much of the region. However, there are some indications that
some cold air will linger across the higher elevations for a period
of time right at the onset and we could see some light freezing rain
occur before a changeover to plain rain. The models have backed off
a little bit on the start time, keeping the precip mainly arriving
after 12Z, but some light precip may move in ahead of the main
shield so keep a slight chance for some mixed precip at the onset
with a quick change to plain rain Friday morning. As the low departs
the region, colder air will arrive and precipitation may end as mix
of rain/snow or just snow before ending.
Sunday...The surface low settles to the north of our area but starts
to move ever so slowly northward as high pressure tries to build in
from the west. This will put a rather tight pressure gradient across
the region and Sunday looks to be a rather windy day across the
region. One hitch this far out is how fast the models move the
surface and upper level lows away from our area. The GFS is slower
than the ECMWF and also has a much deeper and stronger upper level
low. This would keep us windier for longer with a better chance at
some wrap around precip hanging around through Sunday and allow for
colder air to move across the region. Either way, cold air will find
its way back into the Mid-Atlantic and temperatures will drop
considerably from where they were at weeks end.
&&
.AVIATION /18Z MONDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
Today...Light snow will diminish this morning at the Philly
terminals for the most part, but there is a chance of
intermittent light snow at least this morning. Snow may be more
stubborn (i.e., last much of the day) at ILG/ACY/MIV. MVFR CIGs
may linger today at most sites, though some VFR CIGs may occur
at ABE/RDG/TTN. Winds becoming east or northeast below 10 kts.
Low confidence.
Tonight...Conditions deteriorating to low MVFR or IFR with snow
redeveloping from southwest to northeast. Transition to mixed
types is anticipated at the Philly terminals by daybreak. East
to northeast wind around 10 kts. Low confidence.
Tuesday...Prolonged sub-VFR with an array of precipitation types
during the day. General transition from snow to sleet to
freezing rain at PHL and northward, with predominantly rain at
ILG/ACY/MIV. East winds 10 to 20 kts. Low confidence.
