System1: Snow, Ice in West and Midwest

Current Radar and Conditions

Friday and Friday Night

Snow and some ice will build in the northern Plains while expanding eastward into the Midwest. The most significant accumulating snow will be in eastern Montana, northeast Wyoming, South Dakota and northern Nebraska. Friday night, a narrow zone of ice could cause slick travel from northern Iowa southeastward into northern Illinois, northern Indiana, parts of OhioandWest Virginia. This area of mixed precipitation may persist in parts of Ohio and West Virginia into Saturday morning.

Snow will coat the higher elevationsfrom California's Sierra Nevada into the northern and central Rockies as the new storm heads inland along the West Coast. Several feet of additional snow will pile up in the Sierra, where travel will be heavily impacted over Donner Pass on Interstate 80. Snow or a rain-snow mix will also begin to push into the northern Plains.

Monday and Beyond

This storm system will plod through the Midwest Monday and then reach the Northeast by Monday night or Tuesday. At least some accumulating snow is likely alongthe future path of thelow-pressure system. While details are uncertain, forecast guidance indicatesanother coastal low-pressure system might develop off the Eastern Seaboard as the energy arrives in the East. The evolution, track and strength of this storm, once it reaches the East, will determine whether another round of snow, rain, wind andcoastal flooding will occur in the Northeast. This system may linger in parts of the East into next Wednesday or even next Thursday. Here's our forecast overview for next Monday and Tuesday, but keep in mind changes are likely in the days ahead since the event isfive or moredays away.

Monday's Forecast

(Areas in darkest teal have the best chance of snow. Areas in pink may see either rain or snow. Areas shown in green are expected to see mainly rain.)

Tuesday's Forecast

(Areas in darkest teal have the best chance of snow. Areas in pink may see either rain or snow. Areas shown in green are expected to see mainly rain.)

How Much Snow?

One thing is for certain: the Mountain West will see accumulations topping a foot in the higher elevations through this weekend. California's Sierra Nevada will pick up several feet of snow.

Parts of the northern Plains, including the Dakotas, could also see at least six inches or more of snow through this weekend.

In the Midwest and East,it's too early to determinethe snowfall forecast given the uncertainty surrounding the track and strength of the second storm system.
