A new storm, which is currently bringing rain to much of the West Coast, including California, will move onshore this Tuesday. This storm will lead to a widespread lower-elevation rain and mountain snow for the western US through Wednesday. A new storm will then develop on the leeward side of the Colorado Rockies, and this storm will transform into a major winter storm for the Central and Northern Plains as well as the Midwest.

On Tuesday, we’ll see a widespread rain across the state of California. Some locations may receive over six to twelve inches of rainfall while the Sierra Nevada picks up as much as five feet of snow from this storm. There is also the concern for mudslides, however, due to the burn scars from the recent wildfires. Rain showers will also be found in the lower elevations of the Northwest and into much of Nevada and portions of Utah and Arizona. In the colder locations (mostly the mountains), we’ll see snow for the Cascades and portions of the Rockies and the Bitterroots. Then overnight, much of the snow will increase in intensity. Snow will continue for the same locations and will move into the Wasatch Range of Utah and the northern mountains of Arizona, including Flagstaff. This city has not seen any snow since the wet season began on July 1. On average, they should have received 33.9 inches of snowfall through this date. Rain showers will also sneak into southwestern New Mexico, while continuing across the same locations that dealt with rain during the day.

As we get into Wednesday, the moisture will slowly pull to the east. California will dry out by daybreak Wednesday morning, although the Cascades will continue to see snow falling as a new storm system moves into the Pacific Northwest. The lower elevations of Arizona, New Mexico, and Utah will deal with a few light rain showers. All of the Rockies from Montana down through New Mexico will be dealing with a heavy snow throughout the day on Wednesday. By Wednesday evening, a weak area of low pressure will quickly develop in the Colorado foothills. This storm will lead to a more organized area of precipitation. On Wednesday night, snow will gradually dwindle across the Rocky Mountains, while a moderate to perhaps heavy snow will break  out for most of the Central and Northern Plains. From Minnesota through the Oklahoma and Texas Panhandle, snow is expected to continue through the night. The greatest chance for heavy snow will be found in portions of South Dakota, Nebraska, and Kansas.

By Thursday morning, the low will move to the north and the east, and that means the snow will move in that direction with it. So during the morning hours, a light snow can be expected across much of Minnesota and the Upper Peninsula of Michigan. Also northern Wisconsin will get in on some of the snow. Further south, there is a operate batch of snow, which will feature a moderate to heavy snow. This batch of heavy snow will move from central Kansas into central Iowa in the morning. Then in the afternoon, the snowfall will begin to taper in intensity as it moves into the Great Lakes region and clears out by the evening. Most of this snow will move just south of Minneapolis, so the city is only expected to receive up to an inch of snow while from central Kansas though Iowa, where heavier snowfall totals are anticipated, one to three to possibly four inches is forecast.
