What forecasters said that day

The local office's own words before this coastal flood warning 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 coastal flood warning went out at Mar 4, 6:33 AM EST, 3 hours 23 minutes earlier.

Area forecast discussion, Mar 4, 6:33 AM EST, 3 hours 23 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
633 AM EST Sun Mar 4 2018

.SYNOPSIS...
The departing storm over the western North Atlantic will
continue to drift out to sea today and Monday as high pressure
builds into our region from the west. Weakening low pressure is
forecast to move from Iowa to the Great Lakes and Ohio River
Valley on Tuesday. Another low is expected to develop along the
North Carolina coast on Tuesday night. The low is anticipated to
strengthen rapidly as it moves northeastward, passing near Cape
Cod late on Wednesday night before reaching Nova Scotia on
Thursday. High pressure is expected to gradually build into our
region from the west on Friday and Saturday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
630 am update: A broken to overcast deck of clouds continues to
stream south through the area, but it is gradually eroding in
eastern PA and Maryland. Models have slowed the trend of
clearing a little more, so followed suit with this update. Also
updated hourly temperatures, which still were a little too cool
compared to current obs. Otherwise, no changes.

Previous discussion...

The intense low in the western Atlantic is still influencing
our sensible weather, with strong north to north-northwest winds
and a stubborn low-cloud deck overnight across the area.
Infrared satellite imagery indicates the low clouds are
beginning to scatter somewhat just west of our CWA (with very
evident topographical waves in the northerly near-surface flow),
and think this will slowly spread eastward through the day.
Nevertheless, models have trended slower with the gradual
dissipation of the lower clouds today, so have made the sky
grids a little more pessimistic early this morning. This cloud
deck (along with the strong north winds) has hampered cooling
tonight, so hourly temperatures were raised through daybreak
then lowered a little after daybreak to exhibit a more muted
fall and rise in temperatures during this period.

Besides determining the onset/rate of clearing today, the other
main challenge is the maximum temperature forecast. The rather
stagnant atmospheric pattern suggests little change to max
temperatures compared to yesterday. Regarding this, the MAV MOS
was noticeably warm compared to reality yesterday, often with
errors in excess of five degrees. Weighted the forecast heavily
to ECS MOS as well as hi- res 2-m temperature input, as
verification with ECS has been considerably better and the hi-
res input will likely account for the muted diabatic
heating/cooling early in the near-term period better than
statistical guidance. As a result, forecast highs were lowered
about 2-4 degrees, with projections in the low-mid 30s in the
southern Poconos to the mid to maybe upper 40s in the urban
corridor and Delmarva.

With surface high pressure continuing to seep southward from
Canada but very gradually given the blocking pattern in the
Atlantic, the pressure gradient will ease only very slowly. As
such, expect another breezy day, with winds 10 to 20 mph and
gusts 25 to 30 mph at times.

Cannot rule out some flurries in the southern Poconos today,
but currently think the odds are too low for mention.
Nevertheless, this is hinted at in NAM/GFS, so it is at least
worthy of mentioning in this discussion.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/...
A midlevel vort max will be racing south-southeastward this
evening near the Mid-Atlantic coast. This will bring a weak cold
front through the area late in the day and this evening.
Passage will be dry, but tonight's temperatures will likely be a
little bit cooler given the source region of the upstream air.
Additionally, skies will likely be clearer, so nocturnal
radiational cooling will be somewhat enhanced. However, winds
will still be elevated (and may gust a little bit near the
passage of the weak front), so temperatures will likely keep
from tanking (except possibly in the most protected valley
locations). For overnight lows, the MET MOS has been much too
cold recently, though its performance is better in clearer
conditions. As such, I did incorporate its values into the
forecast, though with less weighting than ECS/MAV MOS.

Operational models do break out some precipitation in advance
of the vort max, but well offshore. Thus, PoPs are unmentionable
in the current forecast. Nevertheless, will need to keep an eye
on trends with the vort max, as a westward displacement and/or
more pronounced lift will likely lead to increased clouds at the
very least, especially in the eastern CWA.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
High pressure is forecast to build across our region from west
to east for Monday into early Tuesday. We are anticipating dry
weather and near seasonable temperatures at that time.

The expected weather system for the middle of the new week has
some of the same characteristics as the storm that affected our
region on Friday. However, the system should not be as robust as
its predecessor.

Low pressure approaching from the Great Lakes and the Ohio
River Valley on Tuesday is forecast to weaken. Energy is
expected to shift to another low developing along the North
Carolina coast on Tuesday night. The coastal low is anticipated
to intensify rapidly as it moves northeastward. It should pass
to our east on Wednesday and it is forecast to track near Cape
Cod on Wednesday night.

Sustained wind speeds on land are expected to be in the 10 to
20 mph range with gusts perhaps around 30 mph, not nearly as
strong as our last storm. Precipitation totals may range from
1.0 to 1.5 inches with locally higher amounts. At this time, the
guidance is focusing the heaviest precipitation in our region
on the coastal plain.

The most problematic aspect of the forecast should be the
precipitation type. As the precipitation moves into our region
late on Tuesday, the boundary layer should be warm enough to
support rain at most locations. However, precipitation rates are
expected to increase on Wednesday and the dynamic cooling wild
card will come into play. Wherever the heavier bands of
precipitation develop will likely dictate where the rain will
change to accumulating snow. There remains a great deal of
uncertainty at this point.

The area of low pressure is anticipated to continue moving to
our northeast late in the week and it should allow dry air to
build in from the west at that time.

Another area of low pressure approaching from the west may
bring some precipitation for next weekend.

&&

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Today...VFR with north-northwest winds 10 to 20 kts with gusts
to 25 kts or so. A stubborn cloud deck around 5000 feet has been
slow to erode, and forecasts have trended slower with this
erosion. However, any CIGs should remain VFR. High confidence
in VFR/winds, but low confidence on when skies will
scatter/clear.

Tonight...VFR with north-northwest winds 10 to 15 kts with
gusts to 25 kts, especially in the evening. Moderate confidence.

OUTLOOK...
Monday and Monday night...Mainly VFR.

Tuesday...Mainly VFR. A chance of rain late in the day.

Tuesday night and Wednesday...Conditions lowering to MVFR and
IFR in rain and snow.

Wednesday night...Conditions improving gradually to VFR with
precipitation ending.

Thursday...Mainly VFR.

&&

.MARINE...
630 am update: Brandywine Shoal Light continues to gust to gale
force early this morning, so I kept the gale warning going for
Delaware Bay and the Delaware and southern New Jersey Atlantic
coastal waters, but trends have been down over the past few
hours. A small craft advisory will be necessary once the gale
warning expires or is cancelled later this morning.

Previous discussion...

Gales continue on Delaware Bay and (occasionally) on the far
southern NJ and Delaware Atlantic coastal waters; however, winds
are clearly sub-gale to the north. Have lowered the gale
warning for the northern/central NJ waters, replacing it with a
small craft advisory. Winds should diminish to advisory levels
everywhere by late this morning (if not sooner).

There is a chance of another round of gales this evening and
tonight, especially in Delaware Bay and the southern New Jersey
and Delaware Atlantic coastal waters. Confidence is too low to
forecast this in the northern/central NJ coastal waters, but
think this is probable to the south.

Seas will remain quite elevated today, with 8-14 foot swells
(with very long periods) continuing on the ocean. Continued
beach erosion is likely. Waves of 3-7 feet are expected on
Delaware Bay.

OUTLOOK...
Monday morning...North northwest wind gusts of 25 to 30 knots
are expected. A Small Craft Advisory will be in effect for our
ocean waters and for Delaware Bay.

Monday afternoon and Monday night...Wind gusts should remain
below the Small Craft Advisory criterion. However, wave heights
on our ocean waters are expected to be in the 6 to 10 foot
range. A Small Craft Advisory will be in effect for our ocean
waters.

Tuesday and Tuesday night...Wind gusts should stay below the
Small Craft Advisory criterion. However, wave heights on our
ocean waters are expected to be in the 4 to 8 foot range.

Wednesday...Wind favoring the east to north quadrant with gusts
of 25 to 30 knots expected. Gale force gusts are possible.

Wednesday night...Northwest wind gusts of 25 to 30 knots. Gale
force gusts are possible.

Thursday...Northwest wind gusts of 25 to 30 knots.

&&

.TIDES/COASTAL FLOODING...
The coastal counties of New Jersey and Delaware are now under a
Coastal Flood Advisory. It is in effect until 2:00 PM this
afternoon.

The prevailing wind flow has remained a little west of north
and that has prevented surge values from getting much above 2
feet. As a result, the threat of moderate flooding has been on
the decrease. We are anticipating widespread minor flooding with
this morning's high tide. A few pockets of moderate flooding
are possible, mainly in coastal areas of New Jersey from Long
Beach Island up to Sandy Hook.

The potential for minor flooding should decrease with
subsequent high tide cycles as the strong storm over the western
North Atlantic drifts away from our region. At this time, we
are anticipating some residual minor flooding around tonight's
high tide and one more advisory may be necessary. The need for
an advisory for Monday seems unlikely at this point.

The departing storm will continue to produce a pounding long
period swell along the coasts of Delaware and New Jersey today.
As a result, additional beach erosion is likely.

No tidal flooding is expected for the lower Delaware River or
for the upper eastern shore of Chesapeake Bay.
