Quick-moving Eastern system...multi-day Western powerhouse

Winter storm warnings are flying over the Siskiyous, Sierra, and San Gabriels of California as a multi-day heavy snowfall event takes shape. Whiteout conditions were reported earlier today over Tejon Pass (I-5) northwest of downtown L.A., which was subsequently shut down in both directions. Storm total snowfall through Monday should be at least 4-7 feet in the Sierra, with locally higher totals. Accompanying the snow will be winds gusting at times over 60 mph, especially over the passes and ridge tops. Another concern will be excessive rain. Flood watches are posted from the central California coast into the L.A. Basin. Rain will come in waves of enhanced rainfall, then lighter rain through Monday. Storm total rainfall in the 3-6 inch range is a safe bet for lower elevations, with totals over a foot likely in the foothills and surrounding mountains below snow level. A swiftly-moving weather system will produce a little light snow, sleet and/or freezing rain from the mid-Mississippi Valley to the Ohio Valley overnight. Folks from St. Louis to Cleveland may encounter some tricky winter driving conditions overnight. This system will spread its wintry footprint into parts of the Northeast late tonight into Saturday. Winter storm warnings are flying from central Pennsylvania to northern New Jersey, where icing accumulation is a concern. Winter storm watches are flying for parts of southern New England, including the Boston metro area, where from 1 to 6 inches of snow may fall in a roughly 12-hour period Saturday.
