An intensifying low pressure system has entered the southern High Plains
with showers stretching from eastern New Mexico to the Mid-South. As the
storm's cold front tracks east through Texas this evening, there is the
potential for scattered thunderstorms ahead of the front across southern
and central Plains with the best chance for severe storms in the eastern
Texas Panhandle and western Oklahoma. Further north, the central Rockies
will receive accumulating snowfall through this evening with snow tapering
off over night. As the storm tracks east on Monday, so will the showers
and thunderstorms across the Gulf Coast states and into the Ohio Valley.
There is the potential for flash flooding Monday evening in parts of the
Southeast where some heavy showers and thunderstorms are likely to produce
locally heavy rainfall rates. As the storm's warm front lifts northward
Monday night and into Tuesday, expect showers to reach the Mid-Atlantic
and Northeast Monday night and persist into Tuesday. A swath of wintry mix
is possible across northern New England Tuesday morning.
Speaking of wintry weather, the Midwest and central Great Lakes will see
an initially narrow area of wintry weather Monday morning turn into a more
pronounced band of moderate snow Monday night and into Tuesday. As the
storm intensifies Tuesday morning, heavy snow will set up from the Midwest
to the central Great Lakes. Snowfall accumulations in these areas may
range between 6 to 12 inches with some locally higher totals possible.
Winter Storm Watches have been issued for portions of the Midwest ahead of
this potential winter storm. Along with the heavy snowfall, winds will
pick up in intensity along the northern and western flanks of the storm
late Tuesday into Tuesday night. This could lead to blustery conditions
and reduced visibilities in these areas. Expect snow and gusty winds to
continue across the Great Lakes into Wednesday while colder and drier
conditions filter down the backside of the storm across the Midwest and
into the South-Central U.S..
In the Northwest, a low pressure system is responsible for areas of
showers and mountain snow this afternoon. The Olympics and Cascades will
receive more mountain snow while the valleys and coastal areas see rain.
The storm system will track into the northern Rockies tonight leading to
more areas of mountain snow. Periods of snow will then expand farther east
into the northern Plains as it reaches the northern High Plains early on
Monday. Light snow will accompany a surge of colder air in wake of the
storm and will spread south through the central High Plains and the
central Rockies Monday night and into Tuesday.
