...Active winter weather pattern continues with snow impacting the
Great Lakes, interior Northeast, and Pacific Northwest/Rockies the
next couple of days...

...Moderate to heavy rainfall for the Gulf Coast with isolated
flash flooding possible; some wintry precipitation expected north
into the Appalachians/Mid-Atlantic Friday...

...Surge of arctic air forecast to challenge low temperature
records across the Midwest Thursday and the northern Mid-Atlantic
to New England Friday...

An active winter-like pattern continues across the country with
systems bringing snow to multiple places over the next couple of
days. First, lake-enhanced snow showers will continue for portions
of the Great Lakes following the passage of one clipper-like
system this morning and as another quickly approaches the region
on Friday. Some moderate snow accumulations will focus downwind of
the Upper Great Lakes and Lake Ontario. Light snow showers will
also be possible across the northern Plains today as this incoming
second system passes through. Meanwhile, the departing clipper
system and trailing cold front is expected to lead to a
potentially impactful snow squall event today over the interior
Northeast. These intense, quick bursts of heavy snow accompanied
by gusty surface winds can bring sudden white-out conditions,
which is particularly dangerous to those driving.

To the west, a series of upper-waves dropping southward over the
western U.S. will bring significant snowfall to the Cascades and
ranges of the northern Rockies today, spreading into the central
Rockies Friday. Winter Storm Watches have been issued for snowfall
totals generally between 8-14", with higher amounts upwards of
2-3` possible for the higher mountain peaks. The mountain valleys
will see between 3-6". While accumulations should mainly remain
limited to the mountains, a wintry mix is expected for adjacent
areas of the northern/central Great Basin and northern High
Plains, with rain for the Pacific Northwest.

Moist southerly flow ahead of an upper-wave approaching the
southern Plains/western Gulf has led to an expanding area of
precipiation across the region this morning. Thunderstorms will
focus in vicinity of a quasi-stationary frontal boundary along the
western to central Gulf Coast with more moderate showers further
inland. The system will progress eastward into the Southeast
overnight Thursday and into the day Friday, with thunderstorm
chances lingering to the west along the Gulf Coast. Some locally
heavy rainfall will be possible with an isolated threat for flash
flooding. Wintry precipiation is expected where colder air in
place further to the north, first over portions of the southern
Plains this morning/afternoon, and then eastward from the Ohio
Valley into the central/southern Appalachians and North
Carolina/southern Mid-Atlantic overnight Thursday and into the day
Friday. Winter Weather Advisories are in place for potential snow
accumulations of 1-2" as well as a light glazing of ice.

Conditions remain well below average across much of the eastern
and central U.S. as this winter-like pattern remains in place. Yet
another cold front passage will bring some brutally cold low
temperatures to portions of the Midwest this morning, and then
into the northern Mid-Atlantic and New England Friday morning. Low
temperatures in the negative single digits and teens for the
Midwest and single digits and teens for the northern
Mid-Atlantic/New England may challenge several daily record low
temperatures. Forecast highs the next couple days will vary
depending on the timing of frontal passages, but generally range
in the teens to 20s for the Midwest, the 20s and 30s for New
England, the 30s and 40s for the central/southern Plains east
through the Ohio Valley to the Mid-Atlantic, and the 40s and 50s
for Texas to the Southeast. The High Plains will see a return to
average if not a bit above average conditions with downsloping
winds off the Rockies in place, with highs into the 30s and 40s
north and 50s and 60s south. Conditions will also remain around or
above average for most of the West, with 40s for the interior, 50s
and 60s along the West Coast, and 60s and 70s for the Desert
Southwest. The Four Corners region will see some locally cooler
temperatures with highs in the 30s and 40s.
