What happened

The episode as NWS PHI wrote it up.

Strong low pressure tracked to the northwest of the forecast area on Tuesday into early Wednesday (January 9-10th). A cold front associated with the low swept through the region on Wednesday. In the system’s wake, total rainfall amounts varied from about 1.50 inches up to about 4.00 inches. The rain fell on already saturated soils and there was some snow on the ground that melted and also contributed to the runoff. As a result, river flooding was prevalent across the Passaic Basin, Raritan Basin, and southeast Pennsylvania basins including the Schuylkill and Brandywine. The Brandywine flooding extended in to Delaware. Smaller streams and rivers across northern New Castle County in Delaware, such as the Christina, Red Clay, and White Clay also flooded.

741 PM EST Tue Jan 9 2024

.SYNOPSIS...
A strong area of low pressure moves across the Great Lakes
region tonight and into eastern Canada on Wednesday, dragging a
strong cold front through the region tonight. High pressure will
build back into the region Wednesday night and be in control
through the first half of Friday. Another strong low pressure
system will affect the area late Friday into Saturday. High
pressure briefly returns for Sunday, ahead of another low
pressure system that approaches early next week.

&&

.NEAR TERM /THROUGH WEDNESDAY/...

Rain continues across the region and will only get heavier as
we head into the mid-evening thanks to strong warm advection/isentropic
lift and exceptional upper-level forcing associated with the
approaching closed low and strong jet streak aloft. As the warm
front lifts northward toward us this evening, temps will rise
into 50s for most of the region, possibly reaching 60 as far
north as Philadelphia. Surface winds will increase, with gusts
40-50 mph likely for most of the region and 60 to possibly 70
mph along the immediate coast. These strongest winds will occur
late this evening to around midnight. Further inland, confidence
in winds stronger than currently forecast is low, but could
occur if a low-topped squall line crosses the region with the
surface cold front overnight, also likely to be fairly close to
midnight. For now have included slight chance of thunder in the
forecast, but the chance of the squalls is greater since they
may not have any thunder. Rainfall still looks quite potent with
1-3 locally 4-5 inches.

The weather gets markedly less severe after the cold front
passes overnight, with winds becoming southwesterly 15-25 with
perhaps some lingering gusts to 40 mph late tonight. The rain
will mostly end, though a few showers may linger towards dawn
especially in southern NJ and the Delmarva. Temps will fall back
into the 40s.

For cleanup on Wednesday, expect a somewhat more seasonable and
bearable day, with mostly dry conditions and perhaps some intervals
of sunshine. SW winds will remain a bit strong and gusty however,
and we might need a wind advisory again as gusts could approach
45 mph. Some snow showers may redevelop in the Poconos on the
upslope flow behind the system. Temperatures mostly in the 40s,
30s in the Poconos.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
High pressure will build in from the south Wednesday night
through Thursday night, bringing a brief reprieve to our active
weather pattern this week. Partly cloudy skies Wednesday night
will gradually clear overnight with lows in the mid 20s to low
30s, a few degrees above climo.

Staying on the warm side of climo on Thursday as well with
afternoon highs warming to the mid to upper 40s (mid 30s
Poconos) with partly to mostly sunny skies. High pressure will
move overhead Thursday night, allowing for mostly clear skies
and calm winds. With a warm airmass overhead, however,
radiational cooling will not be as efficient and the low
temperatures are only expected to be in the mid 20s to low 30s,
a few degrees below climo, once again.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
Summary...A strong low pressure system will affect the area
bringing another round of heavy precipitation on Friday and
Saturday, before drying out on Sunday. Another storm system may
approach Monday into Tuesday.

Synoptic Overview...Shortwave energy exiting the Rocky Mountain
region will eject east in combination with a deep upper-level
trough located over the southern Plains on Friday. This energy
and trough is forecast to shift toward the Great Lakes on
Saturday while showing signs of becoming negatively tilted.
Upper flow then becomes relatively zonal on Sunday/Monday aside
for a few pulses of embedded shortwave energy revolving around
the upper low over Canada. At the surface, high pressure near
the Mid-Atlantic will shift offshore on Friday as the surface
low associated with upper trough develops. Similarly to the
Tues/Weds system, this strong surface low will cut up through
the eastern Great Lakes as another strong cold front pushes off
the East Coast on Saturday. High pressure builds over the
southeast US on Sunday and Monday, ahead of yet another low
pressure system that approaches on Tuesday.

For Friday and Saturday...The surface low is forecast to track
once again to our north and west, resulting in our area to be in
the 'warm sector'. Other than a brief period of snow or a
rain/snow mix at the onset for our northwestern counties, this
event will be primarily rain as precip begins Friday afternoon.
Another strong pressure gradient will be in place with a 40-50
mb difference between the surface high and low. Frequent wind
gusts up to 40-50 mph can be expected across the region. Early
estimates show 1-2 inches of rain are possible with localized
amounts up to 3 inches. NBM PotThunder also has a slight chance
for thunder (~20%), so have maintained this mention in the
forecast. Exact details are not quite certain as we still have
to get through the Tues/Weds system first, but the potential
looms for another impactful system to close out the week/start
the weekend. After low pressure departs on Saturday, the area
begins to dry out but strong winds are forecast to continue as
the pressure gradient does not ease until high pressure moves
back into the area later Saturday. High temps for these days
reach into the 40s to 50s.

For Sunday through Tuesday...High pressure builds back across
the area on Sunday and persists for most of Monday. Long range
deterministic and ensemble guidance indicates that another area
of low pressure develops near the southeast US which may
approach our area on Tuesday. Temps for these days appear to be
about 5 degrees below normal.

late tonight with winds 20-30 kts with gusts to 40 kts late.
Seas will build to 15-20 ft overnight then start diminishing
late.

For during the day Wednesday, winds likely remain at or near
gale force thru the day. So, at minimum will need Small Craft
Advisories with perhaps a gale over the ocean waters.

.HYDROLOGY...
Large hydro event underway. Pay attention to the latest warnings
and statements tonight and Wednesday. Widespread rainfall amounts
of 2-3 inches with locally 4 inches is forecast across the area.The
heaviest rain is forecast to continue thru the first half of tonight.
A period of enhanced rainfall rates combined with already saturated
ground, which will be even more swollen given snow melt across
the northern areas, will increase the flooding risk.

There is the potential for moderate to major flooding on some of
our rivers tonight and beyond. There is a heightened concern for
the Passaic and Raritan basins as well as some of the rivers in
southeastern Pennsylvania especially the faster responding ones.
Given the very saturated ground, another round of heavy rain and
snow melt across the northern areas, will all lead to more runoff
into the waterways.

As mentioned, enhanced rainfall rates looks probable tonight.
This could lead to urban flooding and even some winter-time
flash flooding. This is why WPC has issued the MODERATE risk.

Tidal areas may also experience even higher levels during high
tides due to excessive runoff and a period of very strong east
to southeast winds. This is especially true for the northeast
Maryland Shore, Delaware Bay coast, the tidal portion of the
Delaware River, and even our tidal/coastal back bays.

Not everyone is going to see flooding, but if you live next to
a creek, stream, or river that is prone to flooding, or you
travel near one, you need to keep an eye on things. It looks
like flooding will commence tonight. If driving, it's tough to
spot flooding in the dark.

We attach words like MINOR, MODERATE, and MAJOR to river
flooding. What do these words mean?

MINOR FLOODING: Minimal to no property damage, but some public
threat can be expected (e.g. inundation of roads).

MODERATE FLOODING: Some inundation of structures and roads near
streams/rivers are expected. Evacuations of people and/or the
transfer of property to higher elevations can be anticipated.

MAJOR FLOODING: Extensive inundation of structures and roads.
Evacuations of people are on a larger scale. The transfer of
property to higher elevations is needed.

To stay on top of the flooding potential, visit these websites.

probabilities, check out this Hydrologic Ensemble Forecast link:

There is the familiar AHPS website, however you can now preview
our new experimental National Water Prediction Service (NWPS)
website (NWPS will eventually replace AHPS):

If you live in the Passaic or Raritan basins, keep in mind that
inundation mapping is available:

.TIDES/COASTAL FLOODING...
The combination of intense southeast winds, an approaching New
Moon on Thursday, and runoff from heavy rainfall will set the
stage for a significant coastal flooding event is expected with
the high tide cycle this evening, especially for the eastern
shore of Maryland, the tidal Delaware River, and portions of
Delaware Bay. Conditions will be even worse if timed with the
peak of high tide.

The most significant flooding is expected to occur along the
Chesapeake, affecting the eastern MD counties, and in the upper
Delaware Bay as well as the tidal Delaware. Minor coastal
flooding may develop by late afternoon for the eastern Maryland
counties prior to moderate to locally major coastal flooding
developing by the evening high tide and continuing through the
overnight. Moderate coastal flooding will develop with the high
tide cycle tonight for the tidal Delaware River and the upper
Delaware Bay. The strong southerly surge of wind and water will
lead to elevated water levels continuing into Wednesday.
Additional minor to locally moderate coastal flooding may occur
with the high tide cycle later on Wednesday as water will be
slow drain out of the rivers and bays, particularly with some
runoff continuing.

There is lower concern for flooding along the Atlantic coast of
Delaware and New Jersey due to the orientation of the onshore
winds and surge. However, there is greater risk for moderate
flooding across the back bays, particularly Barnegat, so have
upgraded to a warning for Ocean and have extended advisories
southward to Cape May this morning.
