...Pacific frontal system expected to bring heavy snow to portions of the
Rockies and Intermountain West...
...Lake effect snows expected to gradually lessen in intensity today...
...Developing low pressure system across the plains to bring snow from the
northern plains to the Northeast...
An arctic frontal boundary remains draped from the northern Rockies into
the interior Northwest. A Pacific frontal system and upper-level
disturbance will spread moisture inland today where it will interact with
the arctic front to produce snowfall. Snow is expected to be widespread at
the higher elevations of the Intermountain West and central/northern
Rockies, where heavy snow is possible. Farther west snow is expected to
continue across the Cascades through the weekend, with rain at the lower
elevations closer to the coast,the result of persistent onshore flow.
Lake effect snow is expected to continue into today downwind of the Great
Lakes, but should begin to gradually lessen in intensity through the day.
Farther west, a low pressure system will begin to take shape across the
central U.S. as upper-level energy crosses the Rockies and interacts with
a lingering frontal boundary. Snow is expected to develop today from the
northern plains to the upper Great Lakes, spreading east into the lower
Great Lakes and the Northeast on Sunday. Farther south rain is expected on
Sunday from the Ohio valley to the lower Mississippi valley, spreading
into the southern/central Appalachians by early Monday. A few
thunderstorms will be possible along the Gulf Coast.
