NE Snowstorm Tuesday February 13 2024 Finally a NYC snowstorm

A dynamic storm system bringing Severe Weather and Excessive Rainfall
impacts to the Southeast this afternoon will transition to a strong
nor'easter for parts of the Mid-Atlantic and New England by Tuesday.

New storm system to arrive across the Northwest by the middle of the
week with areas of locally heavy rain and mountain snowfall.

A significant winter storm associated with a strong upper-level trough and
associated closed low will cross through the Ohio Valley tonight, which
will continue to interact with enough cold air to produce some areas of
locally heavy snowfall across portions of the Ohio Valley to the north of
the low track. Light accumulations are expected across the Tennessee and
Ohio Valleys tonight.

Farther south and east across the Southeast, and on the warm side of the
strengthening area of low pressure crossing the Tennessee/Ohio Valley, the
northward advance of moisture and instability from the Gulf of Mexico and
its interaction with a strong frontal zone will continue to produce some
heavy showers and thunderstorms across the Carolinas and Georgia early
this evening before pushing into the Atlantic. There's a Slight Risk of
Excessive Rainfall leading to Flash Flooding over portions of southern
South Carolina into central/southern Georgia to account for this threat.

This storm system will arrive across the Mid-Atlantic states tonight and
will transition to a strong nor'easter Tuesday morning as low pressure
exits off the Mid-Atlantic coast near the Delmarva and ejects well
offshore of southern New England by Tuesday night. The concern will
refocus back to winter weather impacts as moisture surging northward ahead
of the low center encounters sufficient levels of cold air for a swath of
heavy accumulating snowfall. There continues to be an unusual amount of
uncertainty with this forecast, particularly with where the axis of
snowfall will develop and occur. The latest guidance suggests heavy
snowfall occurring from southern New England down into southern
Pennsylvania/New Jersey. Generally, between 6-12 inches are probable for
portions of the aforementioned areas. The nor'easter will bring strong
winds to the region on Tuesday which coupled with the heavy snowfall could
damage trees and power lines. The strong winds will also bring a threat
for coastal flooding.

A new storm system meanwhile will arrive across the Northwest by the
middle of the week which will bring areas of heavy rainfall to the coastal
ranges of the Pacific Northwest, and heavy snowfall for the higher
elevations of the Cascades. This snowfall threat will also extend eastward
into the northern Rockies as Pacific moisture streams inland.
