...Impacts from a significant Nor'easter will extend through the
weekend into Monday especially for the coastal sections of the
northeastern U.S. into the Mid-Atlantic...

...Moisture lifted ahead of a weak front could bring locally heavy
rain across Iowa tonight...

...Upper-level moisture drawn northeastward from the twin tropical
cyclones in the eastern Pacific could reach the Four Corners
region by Monday morning...

A strong low-pressure system continues to churn off the coast of
the northern Mid-Atlantic and southern New England this Saturday
afternoon. Additional energy associated with an upper-level vortex
will dig southeastward across the Mid-Atlantic states to merge
with this strong cyclone centered a few hundred miles southeast of
New York City. This dynamical merging will pull the cyclone center
closer toward New Jersey and Long Island through tonight,
resulting in the full force of this Nor'easter impacting coastal
southern New England to the northern Mid-Atlantic by Sunday
morning.  North to northeasterly winds are forecast to strengthen
to gale or storm-force especially near the coast through tonight,
along with more frequent rounds of moderate to occasionally heavy
rain. In addition, major coastal flooding is expected along the
Mid-Atlantic Coast over multiple high tide cycles coming off a
full moon through the weekend. Prepare immediately for significant
inundation in low-lying areas near the shore, including roads
underwater and impacts to homes and businesses. Moreover, large
breaking waves will continue to generate strong rip currents,
beach erosion, road closures, and property damage for the
Carolinas and Mid-Atlantic into Southern New England into Monday.
In addition, waves of heavy rain may lead to inland flooding from
northern New Jersey into southern New England for much of Sunday,
where WPC continues to highlight a Slight Risk (level 2/4) of
excessive rainfall. From late Sunday into early Monday, the
cyclone center is forecast to stall near the New Jersey coast as
the system begins to steadily weaken. However, strong to
gale-force onshore winds are still expected along the New England
coast from Cape Cod northward. Meanwhile, moderate rain can be
expected to linger across southern New England into Monday. Please
see the latest WPC Key Messages for this system at
wpc.ncep.noaa.gov.

Outside of the Nor'easter, weather conditions for the rest of the
country will be relatively less active through the remainder of
the weekend. A slug of moisture extending from Oklahoma to
Minnesota will be lifted ahead of a weak warm front. The rain
could be enhanced by the passage of an upper-level disturbance
across Iowa this evening, where WPC is highlighting a Slight Risk
(level 2/4) of excessive rainfall. By Sunday, a high-pressure
system building into the northern Plains will keep the showers and
thunderstorms more widely scattered along this corridor.  Sunday
night into Monday morning should see new rounds of showers and
thunderstorms blossoming across the northern Plains as a
low-pressure wave forms over the northern High Plains behind the
high-pressure system. Meanwhile, tropical moisture transporting
northeastward from the twin tropical cyclones, Odalys and Polo, in
the eastern Pacific is forecast to reach the Four Corners region
by Monday morning as rain expands across the region with embedded
thunderstorms ahead of an upper-level trough moving onshore into
California.
