Most of the active weather for the next couple of days will be focused
across the central U.S. and will slowly shift east into the Midwest by
Monday morning. This is in response to a vigorous upper-level low
pressure system that will swing across the Southwest today and then
interact with a surge of cool air down from western Canada. Thunderstorms
are expected to develop quickly later today across the southern High
Plains where severe weather will be possible as a cold front surges south
and clashes with warm and moist air lifted northward by the upper low. By
Saturday night into Sunday, the main activities will then gradually shift
east across the central Plains toward the mid-Mississippi Valley as low
pressure waves form along the front. Sunday into Monday morning will see
the potential of heavy rain shifting farther east into the Midwest and
toward the Ohio Valley. Meanwhile, colder air behind the system will
change the rain into wet snow across the higher elevations of Colorado
Rockies Saturday night into Sunday morning. Showers and embedded
thunderstorms can also be expected farther north near/behind the cold
front across the northern Plains today, into the upper Midwest tonight,
followed by the upper Midwest and the Great Lakes Sunday into Monday
morning.
Temperatures will fall precipitously on the backside of the cold front
over portions of the southern High Plains and central Plains beginning
Saturday. High temperatures in the 50s will represent 15 to 30 degree
departures from average for the aforementioned areas. Above average
temperatures will be in place across the Midwest and Southeast this
weekend as upper-level ridging extending from Mexico into Texas remains in
place. Elsewhere, a slow-moving coastal storm will bring another rainy
day across southeastern New England with coastal flooding during high
tides for the northern Mid-Atlantic coast for today before the storm
slowly moves out into the Atlantic on Sunday.
