Prolonged Atmospheric River Will Impact the Northwest Early this Week

A weather system in the Pacific Northwest will produce rain throughout the day, before a potent atmospheric river produces a prolonged round of heavy rainfall, widespread urban and river flooding, and high elevation snow to the region Monday through Wednesday. Showers and thunderstorms may produce isolated damaging winds, a brief tornado, and locally heavy rainfall across parts of Florida today. Read More >

After a shot at lighter snow Monday night, more impactful snow may occur Tuesday night. At this time, impacts are more probable along and north of I-94. Keep an eye on the forecast, as details will change over the coming days owing to warmer air causing a rain/snow mix on the south side of the storm.
Additional rounds of snow are possible Monday, Tuesday night, and Thursday. Temperatures are favored to rise above freezing across a good portion of the area Tuesday, however.
