An arctic air outbreak will bring dangerously cold air to the 
entire forecast area next week, and the threat for a winter 
weather event has increased as well.

Tonight through Friday: Progressive westerly flow aloft will
maintain a dry continental airmass over the forecast area as we go
through the remainder of the work week. A quick moving shortwave
trough is bringing very light rain just to our south today and a
few sprinkles could fall over the lower Pine Belt region into the
evening, but otherwise, expect seasonable temperatures with cold 
nights and cool days continuing.

Friday night through Saturday: A significant weather pattern 
change will begin to take shape as we go into the weekend. Very 
cold arctic air building at high latitudes will begin to surge 
southward as a strong anomalous ridge builds over the East 
Pacific/West Coast region. As this happens, a shortwave trough 
will zip across the lower Mississippi Valley region and bring a 
round of showers to mainly locations along and east of the I-55
corridor. While lift will be strong with this system resulting in
locally heavy downpours, the fast system speed will limit 
moisture return turn and the risk for severe weather.

Saturday night through next Thursday: Arctic air will begin to 
surge into the forecast area Saturday night, with the coldest air 
expected to arrive Sunday night and persist through the end of the
forecast. A strong pressure gradient will develop behind the 
arctic front, and this will support strong surface winds with 
dangerously low wind chill readings. We continue to message for 
the cold given high confidence in low wind chill readings and cold
daytime readings not expected to rise much if any above freezing 
for at least a couple of days. There is a question concerning how
low the temperatures will get early in the week given the 
potential for a frontal wave with cloud/precip development near 
the Gulf Coast region. Eventually, the deeper arctic air will win 
out however behind any departing systems, and this could result in
colder lows later in the week.

Concerning the winter weather potential: Forecast confidence is 
is increasing regarding the threat for a combination of
snow/ice next week, especially in the Tue-Wed time frame. While 
there is still ensemble spread in the timing/strength of a few 
shortwave troughs that will be moving within the polar stream, 
even the colder/drier (northern stream dominant) solutions point 
to at least light snow impacting the area, and the most bullish 
model solutions with stronger shortwave energy suggest that a more
impactful event could materialize with significant snow/ice 
amounts. 

We are messaging the increasing threat for winter weather to line
up with WPC probs for significant snow/sleet melted QPF of 0.25"+
(greatest roughly along/s of I-20 at this point), and we continue
to stress that just light snow/ice accumulation could cause 
significant travel issues with the degree of cold air that is 
expected. It is possible that significant amounts of freezing rain
could materialize as well, but most guidance solutions point to 
snow/sleet being the dominant precip type. Continue to monitor 
forecast updates concerning the potential scenarios. /EC/

Between January 15th and February 24th a total of 1378 railroad cars were
drawn by horses across the frozen Susquehanna River to engines waiting at
Havre De Grace MD. (The Weather Channel)
...1932...
Up to two inches of snow whitened the Los Angeles basin of California. The
Los Angeles Civic Center reported an inch of snow, and even the beaches of
Santa Monica were whitened with snow, in what proved to be a record
snowstorm for Los Angeles. (David Ludlum) (The Weather Channel)
...1952...
A six day snowstorm was in progress in the western U.S. The storm produced
44 inches of snow at Marlette Lake NV, 52 inches at Sun Valley ID, and 149
inches at Tahoe CA, establishing single storm records for each of those
three states. In addition, 24 hour snowfall totals of 22 inches at the
University of Nevada, and 26 inches at Arco ID, established records for
those two states. The streamliner, 'City of San Francisco' was snowbound in
the Sierra Nevada Range, near Donner Summit. (David Ludlum)
...1987...
A powerful storm over the Southern Plateau and the Southern Rockies
produced 24 inches of snow at Colorado Springs CO, including 22 inches in
24 hours, a January record. High winds in the southwestern U.S. gusted to
65 mph in the Yosemite Valley of California. (National Weather Summary)
(Storm Data)
