Weather Summary

A surface low moved eastward across the Great Lakes on Monday and dragged a cold front across the Midwest. Light snow fell in the western and middle Great Lakes; lake-effect snowfall was just starting in lower Michigan.

Also on Monday, energy sent eastward from a retrograding upper low off the Southwest coast caused up to a foot of snowfall at higher elevations, and up to 1/2 foot at lower elevations in the Great Basin, mainly in southern Nevada.

A cold air mass remains over the coterminous U.S. on Tuesday, and little snowmelt occurred in the snowpack.

The surface low over the lower Great Lakes will continue moving rapidly eastward today. A northwesterly winds in the cold air mass behind it will flow over the lower Great Lakes and cause up to a foot of snowfall through tomorrow.

Another clipper system will move to the western Great Lakes tomorrow moving and progress slowly eastward. Around 1/2 foot of snowfall is expected with this system Wednesday and Thursday near the low.

Moderate onshore flow into the Northwest will begin today and continue through Thursday. One to 2 feet of snowfall are likely at higher elevations of the northern Cascades to the northern U.S. Rockies.

It still appears probable that a nor'easter will form off the central East Coast on Friday and bring heavy snowfall to the Northeast and Middle Atlantic regions through the weekend.
