What forecasters said that day

The local office's own words before this areal flood advisory 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 areal flood advisory went out at Mar 31, 6:25 PM EDT, 2 hours 4 minutes earlier.

Area forecast discussion, Mar 31, 6:25 PM EDT, 2 hours 4 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
625 PM EDT Fri Mar 31 2017

.SYNOPSIS...
Low pressure in the Ohio Valley will redevelop in the Mid-
Atlantic this evening and move offshore by Saturday morning.
High pressure builds into the region Sunday and Monday. Another
surface low will move through the Mid-Atlantic on Tuesday. Yet
another low is expected to affect the northeastern U.S. late
next week.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
The primary low over the upper Ohio River Valley was continuing
to weaken early this evening. Meanwhile, the secondary low was
taking shape over Virginia. The secondary low is forecast to
pass off the Delmarva coast late this evening before moving out
to sea.

The feed of moderate to heavy rainfall associated with the low
level jet in advance of the surface low reached into central and
northern New Jersey, extreme northeastern Pennsylvania and
southeastern New York. The feature will continue to shift
eastward this evening and overnight. Its orientation may
transition from south-north to southeast-northwest as the low
slides off the coast. As a result, the potential for moderate to
heavy rain may linger for several more hours from parts of
central and northern New Jersey into the Poconos. Meanwhile, the
potential for moderate to heavy rain and flooding will continue
to decrease in southeastern Pennsylvania, southern New Jersey
and the upper Delmarva. We may be able to end the Flood Watch
early in those locations.

We have received a number of reports of poor drainage area
flooding along with localized small stream and creek flooding.

The wind direction will continue to back as the low moves off
the coast. The wind should be out of the north and northwest by
daybreak throughout our forecast area.

Temperatures are not expected to change much tonight in the
northern part of our forecast area. Readings should remain
stable in the southern part of our forecast area this evening
before falling into the 40s late tonight with the development of
the north to northwest flow.

The near freezing temperatures in the elevated terrain of the
Poconos and far northern New Jersey should result in some ice
accumulation there. The freezing rain in Carbon County PA and in
Sussex County NJ should be rather localized. However, it may be
a bit more widespread in Monroe County PA and a as a result, we
will continue the Freezing Rain Advisory there. Some spots
above 1500 feet could pick up one or two tenths of an inch of
ice.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
Low pressure pulls farther off the northern Mid-Atlantic coast
on Saturday. Wrap-around precipitation may linger in
central/northern NJ through the morning but a general drying
trend is expected.

Gradual clearing is expected from SW to NE during the day.
Enough sunshine and only modest CAA behind the departing storm
will allow for temps to rebound quite nicely by the afternoon.
Forecast highs range from the 40s in the Poconos to near 60F in
S DE and E MD.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
A brief period of northwest upper-level flow occurs Saturday
night and Sunday on the upstream side of the vorticity maximum
moving through the region Friday and Saturday. A broad surface
ridge develops across the eastern U.S. on Sunday, allowing for a
pleasant end to the weekend. Guidance values have come down a
few degrees in the past couple of days for maximum temperatures
on Sunday, and this makes sense given the relatively cool
origins of the surface high and the decreasing trend in surface
winds (collocated with the surface ridge axis) reducing warming
from vertical mixing and subtle downsloping effects. Forecast
maximum temperatures are at or slightly below consensus values
on Sunday, which ends up being near to just slightly above
seasonal averages.

The next in the parade of southern-stream systems ejects into
the southern plains on Sunday, acquiring a negative tilt as it
progresses northeastward through the Mid-South Monday.
Deterministic models are hinting at a subtle predecessor vort
max moving into the Mid-Atlantic by Monday night. Mass fields
appear to respond to this predecessor shortwave trough by
increasing isentropic ascent/low-level convergence Monday night.
Precipitation breaks out well in advance of the surface low
(located near the border of Indiana and Kentucky by 00Z Tuesday)
in a strengthening warm-air advection regime. Models depict a
subtropical fetch aided by a 50-60 kt LLJ Monday night from the
eastern Gulf poleward to the spine of the Appalachians eastward
into the Mid-Atlantic by midday Tuesday. This produces
widespread moderate to heavy rain across the Midwest into the
Mid-Atlantic during this period.

The 12Z model suite still shows quite a few discrepancies in
the evolution of the potent southern-stream vort max moving from
the central/southern plains Sunday night to the Ohio Valley
Monday night, particularly with phasing with the northern stream
and focus of large-scale ascent/pressure falls downstream in
the Mid-Atlantic. The latter has implications on the
development/track of a redeveloping low near the coast on
Tuesday night and how this redevelopment influences our CWA. The
12Z ECMWF, for example, suggests that most of the precipitation
will occur well in advance of the Midwest surface low on Monday
night/Tuesday morning with coastal redevelopment too far
northeast to bring substantial precipitation to the region
thereafter. The 12Z CMC is both slower with the timing of the
surface low redevelopment near the coast and more aggressive in
keeping showery precipitation around through Tuesday night. The
12Z GFS is farthest south with the low track, providing a much
longer duration of precipitation in the area, including warm
sector convection in the southern CWA Tuesday afternoon.

There is growing consensus on a farther north/west surface low
track through the Mid-Atlantic region on Tuesday, but the
slowness of the CMC (a typical bias) and the somewhat better
consistency of the GFS versus the ECMWF during this time frame
prompted me to use a blend of the GFS/ECMWF during this storm's
evolution/impact on our area. As such, added slight chance of
thunder to areas south of the Mason-Dixon Line on Tuesday and
constrained the highest PoPs to the Monday night/Tuesday
periods. Not nearly as confident on QPF and overall societal
impacts of the system to the region, but with the storm
affecting the region currently, continue to think hydrologic
impacts may be more substantial with this second system.

Lowered PoPs on Wednesday given a clearer signal for a dry
period following the early week's system passage.

Regarding the system at the end of the week, major
discrepancies continue, with the CMC painting a picture much
like the system we are experiencing now Thursday-Friday, the GFS
showing primarily cold-frontal/warm-sector convection Thursday
night and Friday, and the ECMWF depicting a hybrid scenario
between the other two. Large spread in the model simulations
exists, but the timing looks to be Thursday and Friday, so
increased PoPs during this time. Additionally, the synoptic-
scale pattern suggests another rather significant system
affecting the area, with potential for considerable
precipitation. A busy week ahead for us.

&&

.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Tonight...Widespread IFR ceilings are expected to continue,
with rain tapering off to spotty showers. Winds gradually back
from the south and east to the north-northwest after midnight,
generally in the 10 to 20 knot range. A lull in the wind is
expected during the early overnight hours as the center of the
low makes is closest approach to the area.

Saturday...VFR, with northwest winds gusting up to 20 KT at
times.

OUTLOOK...
Saturday night through Sunday night...VFR. Northwest winds
around 10 kts becoming light/variable Sunday night. Confidence
well above average.

Monday...Increasing cloudiness with a chance of sub-VFR
conditions by late in the day. Winds becoming east/southeast and
increasing to 10-20 kts by afternoon. Confidence average.

Monday night and Tuesday...MVFR/IFR CIGs/VSBYs and rain likely.
East to southeast winds continuing 10-20 kts with higher gusts
near the coast. Confidence above average.

Tuesday night...Sub-VFR conditions may improve during the
night. Winds switching to north around 10 kts, higher near the
coast. Confidence below average.

Wednesday...VFR. Winds may become more northeasterly during the
day but should generally be around 10 kts. Confidence below
average.

&&

.MARINE...
SCA continues for our southern waters (south of Great Egg
Inlet, including DE Bay), with Gale Warnings to the north
through Saturday morning. Easterly gales late this afternoon
into early evening may briefly subside late tonight as the low
moves before turning N-NWly and increasing to near gale force
behind the departing low Saturday morning.

OUTLOOK...
Saturday night and Sunday...Winds rapidly diminish, but seas
will remain elevated through at least Sunday morning.

Sunday night and Monday...Sub-advisory winds/seas expected.

Monday night and Tuesday...Small craft advisory conditions
likely. Marginal threat of gale-force southerly wind gusts on
Tuesday. Rain and restrictions in visibility are likely.

Tuesday night and Wednesday...Marginal small craft advisory
wind gusts possible Tuesday night. Seas may remain above 5 ft
through Wednesday.

&&

.HYDROLOGY...
Widespread 1 to 3 inch amounts are expected across much of
eastern Pennsylvania, northern Delmarva, and the coastal plain
of southern New Jersey, with the heaviest of the remaining
precipitation expected through this evening. The potential for
flooding along area streams and creeks, as well as urban and
poor drainage flooding, continues until this rain moves through,
so the Flood Watch continues as well.

Potential flooding can be broken down into three different
categories...low lying/poor drainage...smaller creeks and
streams, larger rivers. The runoff will make it to smaller
creeks and streams causing rises and possible flooding into
early Saturday. Some larger river flooding is possible beginning
Saturday and could persist across a few spots into next week.

In terms of river flooding...for the Delaware River, 5 to 10
foot rises could be expected depending on location through the
weekend. The combination of snowmelt and rainfall is yielding 10
ft rises at Riegelsville. This would be enough to bring water
levels into Action Stage late Saturday night into Sunday.
Elsewhere along the river, Action Stage is approached, but not
exceeded.

Across the Passaic Basin, both Boonton Below and Pine Brook hit
action stage on Sunday. Portions of the Passaic won't crest
until next week. That being said, further rises could be
expected into Monday and Tuesday.

The Millstone River in the Raritan Basin is forecast to hit
Action Stage Saturday. Water levels reaching minor flooding
can't be ruled out here. Expect causeways to be closed.

Further south in NJ, the Rancocas River at Pemberton is
forecast to approach Action Stage on Sunday.

Currently no forecast points in PA are hitting Action Stage
levels (or higher).

&&

.TIDES/COASTAL FLOODING...
A Coastal Flood Advisory continues along the northern New
Jersey coast for minor flooding associated with tonight's high
tide.

As low pressure moves to the New Jersey coast tonight, the
onshore flow will strengthen, with gale force gusts over the
coastal waters. Despite astronomical tides decreasing with the
passage of the new moon, the onshore flow is expected to lead to
around 1.5 feet of surge, leading to minor flooding. There will
also be ongoing heavy rainfall around the time of high tide
that will exacerbate the flooding. In addition, beach erosion is
a concern with 5 to 10 foot seas offshore.

&&
