North Atlantic Coastal Waters, 2021

Waterspout in North Atlantic Coastal Waters, May 8, 2021

May 8, 2021 · NWS PHI · 1 event in 1 county or zone

A pocket of cold air aloft associated with upper level low pressure was overhead of the mid-Atlantic United States on May 8. This led to very steep lapse rates in the region, which combined with some modest diurnal heating to cause scattered to widespread convection to develop.

What happened

The episode as NWS PHI wrote it up.

A pocket of cold air aloft associated with upper level low pressure was overhead of the mid-Atlantic United States on May 8. This led to very steep lapse rates in the region, which combined with some modest diurnal heating to cause scattered to widespread convection to develop. Convection mainly took the form of weak showers with isolated rumbles of thunder. Several showers produced small hail thanks to the cold air aloft. The environment was also favorable for the development of cold air funnels and waterspouts. A particularly strong convective cell developed in eastern New Jersey during the mid-afternoon hours. The cell exhibited some rotation on radar, and was observed to produce a waterspout as it moved offshore.

What forecasters said that day

The local office's own words before the first event, 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 the first event at May 8, 11:52 AM EST, 2 hours 23 minutes earlier.

Area forecast discussion, May 8, 11:52 AM EST, 2 hours 23 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1252 PM EDT Sat May 8 2021

.SYNOPSIS...
A weak area of low pressure and associated cold front will
shift to our east, then weak high pressure follows for tonight
into early Sunday. Low pressure is forecast to track across our
area Sunday night into Monday morning, with a cold front
crossing our area during Monday. Strong high pressure builds in
later Tuesday and Wednesday before weakening and shifting
offshore during Thursday. Low pressure moving across the
southern states Thursday may then track near our region Friday.

&&

.NEAR TERM /THROUGH SUNDAY/...
We received a few reports of small hail from the New Jersey
counties of Middlesex, Monmouth and Ocean late this morning. It
was associated with a band of showers that was lifting to our
northeast at midday.

As weak instability increases through the afternoon a few
rumbles of thunder may be possible, although SPC's calibrated
thunder probs from the HREF are only in the 10-20% range. So for
the time being I've opted to keep thunder out of the forecast
because I tend to think we're mainly looking at the potential
for a few isolated moderate to heavy showers with decent
updrafts that could produce pea size hail but not looking at
storms that will have enough charge separation distance to
produce much lightning. The NAMnest does show that the storms
could eventually coalesce into a line and produce a bit of a
bowing segment towards DelMarVa however I haven't quite bit on
this particular solution.

The activity should wane into the late afternoon as the vort
max departs offshore. Expect mostly cloudy skies and highs
mostly in the 50s with some areas in far southern New Jersey and
Delmarva maxing out near 60 degrees.

Heading into the evening hours, the mid level wave tracks well
offshore and a brief period of ridging should bring quiet
weather to the Mid Atlantic. Light northwest winds will
eventually become westerly with neutral temp advection through
the night. With clearing skies Saturday night expect temps to be
on average about 3 degrees colder than this evening with temps
sitting in the low 40s.

Sunday starts quiet before clouds increase ahead of the next
system. Guidance has continued the trend of slowing down the
speed of the warm front with showers expected to move eastern PA
and norther NJ beginning in the late afternoon under strong
warm air advection. Highs should warm into the upper 50s to low
60s which is still some 10 degrees below normal for early May.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
The guidance remains in good agreement that the center of a
closed low is just north of the Great Lakes Sunday night and
Monday, then it amplifies as it gradually slides east-
southeastward Monday night. Fast moving energy ejecting east-
northeastward well ahead of this amplifying trough will drive
surface low pressure across our area later Sunday night into
Monday morning.

Since the surface low is forecast to track across our area, at
least a portion of the region will get into the warm sector
although the northward extent of this will depend on the exact
track of the surface low. This is forecast to result in
temperatures rising some Sunday night, especially from the
Philadelphia metro south and eastward. This will be enhanced by
a 40-50 knot southwesterly low- level jet accompanying the
surface low. In addition, some areas should get into the 70s
Monday as long as enough sunshine can return. It looks like a
period of steady rain Sunday night ends early Monday. The bulk
of the rain is looking to fall across our northern zones, with
much less farther south.

Depending on the amplification of the incoming trough, there
could be some additional shower development through the
afternoon associated with the daytime heating. This may have to
battle some incoming drier air though which would act to limit
the development, and it appears portions of Delmarva to perhaps
far southern New Jersey has the best chance given the quick
movement of the system. Overall there does not appear to be much
forcing remaining and therefore kept PoPs on the lower side
after the initial rain early Monday morning. While some
instability is possible, the window of opportunity looks to be
short-lived and therefore any thunder potential may be low.
Additional drying is expected to occur Monday night.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
Summary...Dry for awhile along with temperatures possibly
getting to or slightly above average especially later in the
week, then it may start to turn unsettled to end the week.

Synoptic Overview...A large upper-level trough across eastern
Canada is forecast to amplify southward across much of the
eastern U.S. into Tuesday, then lift out some Wednesday. Another
upper-level trough from the Plains is then forecast to shift
eastward to the East Coast by Friday. At the surface, strong
high pressure builds in later Tuesday although it should weaken
especially into Thursday as it shifts offshore. The secondary
incoming trough Thursday should result in low pressure tracking
across the southern states. We may still remain protected enough
from the weakening surface high despite it shifting more
offshore, although some guidance has some moisture getting
northward into our area Friday as the southern low may try and
turn north-northeastward.

For Tuesday and Wednesday...Strong high pressure builds in
later Tuesday, then weakens as it shifts eastward and eventually
offshore Wednesday night. This results in dry conditions but
also temperatures will be on the cooler side. Although a few
showers are possible Tuesday up north, the core of the upper-
level trough may miss us to the north and therefore kept the
forecast dry. A breezy day is expected Tuesday with a tight
pressure gradient in place due to incoming strong high pressure
and low pressure exiting New England. As some energy ejects out
of the Plains, surface low development is forecast to take place
along a frontal zone draped across the Gulf Coast states. It
looks like we remain under the umbrella of high pressure and
therefore a dry forecast remains for Wednesday.

For Thursday and Friday...As an upper-level trough shifts
eastward and arrives in our region into Friday, a surface low
across the Southeast U.S. may get pulled far enough north in the
form of a coastal low to give us some showers. Some guidance
however shows this system cruising safely out to sea and
bypassing our area. Opted to lower the PoPs especially for
Thursday, then carried chance PoPs for Friday given the
uncertainty.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

This afternoon...Mainly VFR with additional showers and
brief/localized restrictions possible. Northwest winds around 10
knots with gusts to 20 knots. High confidence on pattern with
low to moderate confident on specific timing of restrictions.

Tonight...VFR as skies clear and winds become westerly 5 to 10
kts. High confidence.

Sunday...Mainly VFR. Rain in the afternoon may lead to periods
of MVFR generally from the Philly terminals north and west.
Southwest to south wind 5 to 10 knots. Moderate confidence.

Outlook...

Sunday night and Monday...A period of sub-VFR conditions
probable along with some rain Sunday night and Monday morning,
otherwise VFR ceilings. Southwest to southeast surface winds
5-10 knots, becoming southwest to northwest Monday 10-15 knots
with gusts to 20 knots. A period of low-level wind shear
possible Sunday night and early Monday morning. Moderate
confidence.

Tuesday...VFR. Northwest winds around 15 knots with gusts 20-25
knots. High confidence.

Wednesday...VFR. Northwest wind 10-15 knots. High confidence.

&&

.MARINE...
Below SCA thresholds as winds continue to shift to the west and
northwest increasing to 10 to 15 kts. Wind gusts of 20-25 kts
are expected this evening generally across the southern Delaware
Bay and adjacent Atlantic waters, but the higher end of the
gusts will likely only be for a couple of hours and seas should
be only 1-3 feet on a four to five second period thus I've opted
not to issue anything at this point.

Waves on our ocean waters should be 2 to 3 feet. Waves on
Delaware Bay are expected to be 2 feet or less.

Sunday...No marine headlines are anticipated.

Outlook...

Sunday night...Small Craft Advisory conditions probable as
southwest winds increase and seas build. Some warmer air will be
arriving ahead of a cold front, therefore the extent of the
vertical mixing is a little less certain.

Monday...Small Craft Advisory conditions probable at least in
the morning. Gusty winds shift to the west and northwest then
diminish some through the day. Elevated seas will subside into
Monday night.

Tuesday and Wednesday...Small Craft Advisory conditions are
possible, with conditions improving during Wednesday.
