$$What forecasters said that day
The local office's own words before this coastal 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 coastal flood advisory went out at Apr 30, 9:34 AM EDT, 46 minutes earlier.
Area forecast discussion, Apr 30, 9:34 AM EDT, 46 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
934 AM EDT Thu Apr 30 2020
.SYNOPSIS...
An area of low pressure over the Great Lakes will weaken today
while an area of low pressure over the southeast US will
gradually move northeastward and strengthen. This low will push
a warm front north into the region today and then push a cold
front through the region late tonight into Friday morning.The
low will linger nearby or just to our east Friday before weak
high pressure builds in for Saturday. Another storm system then
approaches from the west late Sunday into Monday. High pressure
looks to then briefly move in next Tuesday before another system
could affect the region by the middle of next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
920 AM Update: south-north oriented plume of heavy rain is just
off to our west but will be moving in within the next couple
hours as it gradually translates eastward. No changes in
rainfall thinking at this time. However big change with this
update was to increase the wind/gust forecast and upgrade to
High Wind warning for all of southern NJ, Philly and Delaware
Counties in PA and all of Delaware. Based on latest obs, trends,
and examining forecast soundings think we should be able to mix
down S/SE winds within the lowest 1500 feet within the warm
sector and this would indicate from the profiles that 40-50+
knot wind gusts will be doable for the aformentioned
zones...especially near the Delaware Bay due to funneling
affects. The Wind Advisory buffers zones to the north as far as
Berks County east through Montgomery and Bucks Counties in PA
and then through Mercer and Middlesex Counties in NJ.
Previous Discussion: A highly amplified mid-lvl low centered
near Michigan will slowly progress eastward during the day
today, while the primary surface low will begin to decay and a
secondary low over the southern Appalachians will gradually
intensify and slowly move northeastward. This storm system will
present multiple hazards, including the potential for strong
wind gusts and the potential for heavy rainfall and associated
hydrology impacts.
Winds...
A strong low level jet will continue to develop as the
surface cyclone deepens over the Great Lakes region. The
pressure gradient will rapidly tighten this morning and 925mb
winds increase to 60 to 70kts just ahead of a frontal boundary.
The jet maximum sets up over DelMarVa and wanes further inland.
So keeping this in mind, models continue to suggest that we'll
see a decently mixed boundary layer. This means that areas over
DelMarVa and adjacent to Delaware Bay will be in for a very
gusty day. Latest trends in the hires guidance point to a low
probably but high impact wind event with gusts potentially as
high as 60-65kts along the Delaware Bay. I suspect that NAMnest
is overmixing the gusts but even reducing the explicit wind gust
from the NAMnest by 10 kts still results in 50kts along the
land-sea interface of DE and southeastern NJ. Lapse rates in the
1000-925mb layer steepen up to 8-9C just ahead of the front
which is when the highest winds will be expected to mix down.
Unfortunately this also corresponds to when the jet max is
located over the region.
Looking at the HREF probabilities there's a 90% contour of sustained
winds in excess of 30kts for Sussex DE and southeast NJ with and
ensemble max sustained wind between 35-45kts. Considering the chance
for sustained winds nearly reaching the advisory criteria for wind
gusts and the strong mixing potential, I've opted to upgrade the
Wind Advisory to a High Wind Warning for the coastal locations in
Sussex DE, Cape May County and coastal Atlantic county. The highest
wind gusts will likely peak between 2 to 6 pm this afternoon just
ahead of convective line. Winds gusts will be higher on land than
the waters as the cooler sea surface temps will promote just enough
stability to not see a 3-4 hour duration of Storm Force winds
however a few brief storm force gusts right on shore can't be ruled
out.
Further inland the winds do not appear to be quite a strong, and so
the Wind Advisory still remains in place. As the evening crew
mentioned however, with the strong low level jet in place, its
certainly possible that a few of the stronger convective storms
could have the potential to mix down stronger winds potentially
leading to severe thunderstorms.
Winds will start to relax this evening behind the front as an
abrupt shift from southeast to southwest occurs behind the front
and mixing ends quickly.
Heavy Rainfall...
Regarding the heavy rain threat, early morning guidance continues to
depict an area of fairly widespread heavy rainfall slowly
progressing eastward into our area this afternoon ahead of the
system's cold front. Although the actual front will become a bit
less defined thermodynamically as the northern (primary) low
weakens, the precipitation shield is expected to intensity as
moisture streams northward via the LLJ and continued strong dynamic
lift occurs ahead of the mid-lvl system. High-resolution guidance
has trended slightly slower with bringing the heavier precipitation
into our area and consequently it may not nose into western areas
until mid (or even late) afternoon. Prior to the heavier rainfall
this afternoon there may be some lighter precipitation near the
increasingly diffuse warm front, however this rainfall is expected
to be light and largely focused over the usual southerly upslope
areas. This evening the heavier rainfall will progress eastward and
is largely expected to have cleared the area by early Friday AM
(although some showery precipitation may remain).
There are still discrepancies on both the forward progression and
intensity of the heavier rainfall today/tonight and consequently
precipitation amounts vary widely across the board with lower end
guidance (e.g. the GFS/00Z HRRR) depicting areal averages in the
0.75-1.5 inch range while on the higher end (e.g. the HRW NMMB and
the EC) paint a wide swath of 2-3+ inch amounts. Generally went with
a middle ground solution in line with the NAM 3km/RGEM which
forecasts 1.5-2.5 inches over the bulk of the area with an area of
lower amounts (nearer to an inch) along the NJ Coastal Plain and an
area of nearly 3 inches over the Poconos. Admittedly there will
almost certainly be convective elements and mesoscale features which
will make the actual rainfall field much messier than what is
forecast. With these numbers being very similar to the previous
forecast, saw no reason to modify the existing Flood Watch.
&&
.SHORT TERM /FRIDAY/...
The Mid-lvl low will move overhead on Friday but will be
filling as it does so. Although we will be certainly drier than
Thursday, there will be enough lingering moisture to support
continued showery precipitation through much of the day. Given
cold air advection aloft, the latest guidance indicates that
instability may be sufficient to generate convective
precipitation and potentially even some thunder. Consequently
added a slight chance of thunder to the forecast for Friday
afternoon, and bumped up QPF amounts slightly (although with
precipitation having a convective texture these are highly
uncertain). Fortunately the wind fields calm down considerably
on Friday so any severe threat looks limited, however moderate
rainfall in any convective cells could exacerbate any lingering
hydro issues from Thursday nights rainfall. Otherwise expect
mostly cloudy skies with highs in the mid to upper 60s.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
For the long range, there will be a brief reprieve in the active
weather for Saturday as weak ridging builds in to the south.
There could still be a couple lingering showers early in the day
but otherwise it should be mostly dry with variable cloud cover
and seasonable temperatures.
Tranquil weather should continue at least into the first half of
Sunday before the next low pressure system with its associated
cold front approaches from Ontario. This could bring some
showers into mainly eastern PA zones by late day. Ahead of this
system temperatures will warm with highs in the low 70s for most
areas except cooler for the coast and the southern Poconos.
The aformentioned system will move through with some showers
and even a few possible storms Sunday night into early Monday
before we should get another reprieve by late day Monday as the
system moves away. High pressure looks to move in for next
Tuesday before the next system could affect the region by the
middle of next week.
&&
.AVIATION /14Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
Rest of Tonight...MVFR ceilings will continue through the rest of
the evening perhaps briefly lifting to VFR before lowering back to
MVFR. Southeast wind 10 to 15 knots with gusts of 20 to 25 knots.
Low level wind shear is expected for most of the evening as a low
level jet of 40-50 kts will develop with the potential to also cause
some low level turbulence. High confidence.
Thursday...Generally MVFR conditions in the morning, lowering to a
mix of MVFR/IFR in the afternoon. Rain showers will overspread the
region from the west between about 15Z and 18Z. The rain will become
heavy in the afternoon with isolated thunderstorms. Southeast wind
15 to 20 knots with gusts of 25 to 35 knots inland with gusts up to
40kts anticipated at ILG/ACY/MIV. The low level jet intensifies
during the morning with low level wind shear and turbulence
expected. Medium to high confidence on the wind, and medium
confidence on the flight categories.
Outlook...
Thursday night...Generally IFR conditions in rain showers. The rain
will be heavy at times in the evening with isolated thunder storms.
Southeast wind 10 to 15 knots with gusts around 20 knots, becoming
southwest 5 to 10 knots. Medium confidence.
Friday...MVFR/IFR conditions improving to MVFR. Rain showers likely
with some isolated thunderstorms possible. West to northwest wind 5
to 10 knots. Medium confidence.
Friday night...Generally VFR. Showers will be clearing the region. A
chance of showers. West wind around 10 knots. Medium confidence.
Saturday...Mainly VFR. Northwest wind 10 to 15 knots. Medium
confidence.
Saturday night...Mainly VFR. Northwest to west wind 5 to 10 knots.
Medium confidence.
Sunday...Mainly VFR. A chance of showers in the afternoon. Southwest
wind around 10 knots. Medium confidence.
Sunday night...VFR/MVFR conditions with a chance of showers.
Southwest wind around 10 knots , becoming northwest. Medium
confidence.
Monday...VFR/MVFR conditions with a chance of showers. Northwest
wind 10 to 15 knots. Medium confidence.
&&
.MARINE...
SCA continues through the rest of the overnight hours as southeast
winds 15-25kts should occasionally gust to 30 and seas continue to
build to 5 to 8 feet for the Atlantic waters. Heading into the
morning Gale conditions are expected as winds increase out of the
southeast 20 to 30 kts with gusts to 40 across most of Atlantic
Waters with the winds being slightly higher across the southern
Waters adjacent to DE and southern NJ with gusts potentially
approaching storm force. Seas will continue to build under a
southeast fetch with wave heights developing to 8 to 11 feet on the
ocean and 5 to 7 feet at the mouth of the Delaware Bay.
Showers with isolated thunderstorms are expected late in the day and
some of these storms could transport strong winds gusts down causing
winds gusts to be in excess of 45-50kts.
Overnight on Thursday winds should veer from southeast to southwest
behind the cold front and drop to 5-10 kts. SCA will go into effect
as soon as the Gale Warning is dropped due to seas remaining 5-7
feet through much of Friday
Outlook...
Friday...Southwest winds 10 to 15 knots. Seas initially 7-10 ft.
Friday night...West winds 10 to 15 knots with gusts up to 20 knots.
Waves on our ocean waters should decrease to 5 to 7 feet.
Saturday...Seas decreasing below SCA criteria during the day on
Saturday with NW winds 10-15 kts gusting to 20kts.
Saturday night through Monday...Sub SCA conditions.
&&
.HYDROLOGY...
A heavy rainfall event is expected over the area starting
this afternoon and potentially lingering into Friday morning.
At this time forecast precipitation totals are forecast to be in
the 1.5 to 3.0 inch range with amounts generally increasing
with westward extent (e.g. the lowest totals in the coastal
plain and highest totals in the Poconos). Locally higher amounts
are possible particularly in the higher terrain of the Poconos
and NW NJ, while lower amounts (e.g. nearer to 1 inch are
possible in the NJ Coastal Plain).
A flood watch is in effect for the forecast area, apart from
the NJ coastal plain, from Thursday afternoon to Friday
afternoon. At this time the greatest threat for small stream and
urban flooding looks to be over the urban corridor and
locations in eastern PA. However there will also be significant
rises on the main stem rivers with many points expected to get
into at least action stage within the Flood Watch. Currently,
Pine Brook is the only point forecast to go over flood stage.
&&
.TIDES/COASTAL FLOODING...
Have issued a coastal flood advisory for the eastern shore of
Maryland with this morning's package as water levels at
Tolchester and Claiborne look to crest above thresholds with
the high tide occurring late this morning into early this
afternoon. Spotty minor flooding will be possible with this
morning's high tide cycle on the tidal Delaware/Upper Delaware
Bay, water levels are expected to be higher with the high tide
occurring late this afternoon/early this evening. Will hold off
on a product for now as the northward extent of advisory-lvl
flooding is uncertain. Note with the heavier precipitation
potentially trending a little later it is unknown if the
freshwater runoff will be a significant factor with the
afternoon/evening high tide. At this time tidal flooding does
not look likely over most of the ocean sites although some
spotty minor flooding will be possible in back-bays.
