Chilly Temperatures Will Encompass A Significant Section Of The

Lake Effect Snows Are Expected To Impact The Major Great Lakes
Through Monday...

The Overall Pattern Across The U.S. Will Be Rather Chilly As
Modified Arctic Air Has Worked Its Way Southward From Central

A Strong Cold Front Had Earlier Swept Off The Eastern Seaboard Last Night Which Ushered In These Cold Temperatures. In Addition ...The Surface Low Associated With This System Has Strengthened Significantly Thereby Enhancing The Overall Wind Field Across The Northeastern Tier Of The Country.

This Combination Of Below Normal Temperatures And Breezy Conditions Will Make It Feel Quite A Bit Colder To Conclude The Weekend.

Additionally...The Synoptic Pattern Should Remain Conducive For
Lake Effect Snow Production Downwind Of All Of The Great Lakes.
Deep-Layered Westerly Flow Will Be Sustained As The Arctic Air
Overrides The Still Mild Lake Waters. This Sharp Temperature
Gradient Above The Lake Surface Should Lead To Vigorous Lift
Spawning Numerous Snow Showers Downwind Of The Lakes.

Western Canada Toward The Interior West. Mid-Level Energy
Accompanying These Impulses With The Added Contribution Of Upslope Flow Will Result In Snow Over The Higher Terrain Of Central Idaho Eastward To The Nebraska Panhandle. The Heaviest Amounts Should Congregate Over The Grand Tetons Along With The Bighorns With Up To A Foot Of Snow Possible Across The Former.

Looking Down To The Western Gulf Coast...Light Showers Should
Break Out By Early Next Week As Return Flow Commences From The
Gulf Of Mexico. This Should Also Allow High Temperatures To
Rebound Back Into The Upper 70s By Monday. In Stark Contrast...The
Upper Midwest Will Struggle To Get Out Of The Teens For A High On
The Same Day.
