Light rain and snow showers will continue over the Lower Great Lakes and New England Sunday night into Monday...on the backside of a surface low and cold front lifting out towards the Canadian Maritimes. As the system departs...an arctic boundary dropping down from Canada will begin its plunge through the Nation. Plummeting temperatures and gusty winds will make for blustery conditions behind the front...which is expected to reach the Great Lakes...Midwest...and Central Plains by Monday morning...and then dive southeastward through the Northeast...Tennessee Valley...and Southern Plains by Tuesday morning. Moisture will be extremely sparse throughout the Nation...but light snow showers will be possible with the frontal passage...and upslope flow behind the front should streak light snow across Montana Sunday night into Monday. Also...conditions should become favorable for lake effect snows as the front clears the Great Lakes region. An anomalous surface high filling in behind the front will keep much of the Central and Eastern U.S. dry and cool through the middle of week. West of the Continental Divide...a system spinning up in the Eastern Pacific will begin to inch towards the West coast the next few days. Some light to moderate precipitation is expected with the system's cold front approaching the Pacific Northwest and Northern California coasts Monday night and Tuesday. Elsewhere across the Nation...easterly flow should continue to bring light shower and thunderstorm activity into the southern tip of Florida the next few days.
