An area of low pressure is set to strengthen throughout the day as it
tracks into the Southern Plains. On the northern/colder side of the storm,
periods of snow will transpire across the southern and central Rockies and
High Plains this morning. Roughly 3-6 inches of snow are possible in the
High Plains of Colorado and New Mexico with over a foot of snow expected
in the higher elevations of these states. Within the storm's warm sector
and along its warm front, widespread showers and thunderstorms will spread
throughout the Central and Southern Plains where a Marginal Risk for
excessive rainfall has been issued. Some storms could be severe this
afternoon, especially in southern Oklahoma and north Texas where the Storm
Prediction Center has a Slight Risk in place. The storm heads into the
Midwest on Tuesday, bringing showers to the Upper Mississippi Valley and
scattered thunderstorms to the middle Mississippi River Valley. The lower
Mississippi Valley has the better odds of witnessing severe weather and
excessive rainfall Tuesday afternoon and into Tuesday night.
Farther west, another area of low pressure and its associated cold front
usher in bouts of showers and mountain snow to the Northwest today. The
heaviest snowfall totals are anticipated in the northern Rockies and in
the Cascades where the highest elevations are forecast to receive over a
foot of snow. The cold front plunges south Monday night and into Tuesday,
delivering a fresh injection of much below normal temperatures to the
Great Basin and Four Corners region on Tuesday. Light snow accumulations
are expected in these regions on Tuesday, but an amplifying upper trough
over the Southwest will result in heavier periods of snow developing in
the southern Rockies Tuesday night into Wednesday morning.
Elsewhere, fire weather conditions remain at Elevated to Critical levels
in parts of the Southwest today and Tuesday due to blustery winds and low
humidity levels. In the East, a dome of high pressure stretching from the
Mid-Atlantic and Northeast to the northwest Atlantic ensures pleasantly
mild temperatures and mostly dry conditions stick around through Wednesday
morning.
The key states that we'll be diving into include Colorado, Kansas, Oklahoma, Texas, New Mexico, Louisiana, Mississippi, Illinois, Minnesota, Wisconsin, Washington, California, and Arizona.
