Atmospheric River Impacting California

A major winter storm with an active atmospheric river is inundating California the next few days with a tremendous amount of moisture. Heavy to excessive rainfall is likely from central to southern California that may produce flooding along with mudslides and dangerous debris flows near recent and vulnerable burn scars. A significant amount of snow is anticipated in the Sierra with feet of snow. Read More >

Heavy snow fell across far Northern Indiana and southwestern lower Michigan starting New Years Eve night and continuing through early Tuesday. Rapidly intensifying low pressure tracked out of the southern plains into parts of Indiana and Ohio. The heaviest snowfall from the system occurred along and borthwest of a Logansport to Columbia City to Montpelier OH line with some locations reporting upwards of 15 to 20 inches before the system moved away.

While the widespread snow departed with the area of low pressure, bands of lake effect snow setup across much of the area with several more focused and intense bands evolving and moving across northern parts of the area. This allowed for isolated increases in snowfall totals downwind of the lake with some locations seeing 3 day storm totals over over 2 feet of snow.
