The caboose in a train of storms from the Pacific will spread a swath of heavy snow and drenching rain from the central Rockies to the central Plains next week.
The latest indications are that an area of heavy precipitation will set up near I-70 in Colorado and I-80 in Wyoming then drive eastward along the I-80 corridor over the Plains.
Denver, Colo., Casper, Wyo., Scottsbluff, Neb., and Rapid City, S.D., are among the cities that could pick up heavy snow from the storm centered on Tuesday.
Part of this area has the potential to pick up a foot of snow or more.
Farther east, over lower elevations on the Plains and into part of the Midwest, drenching rain will fall from Grand Island, Neb., eastward to Omaha, Sioux Falls, S.D., Des Moines, Iowa, and perhaps Chicago progressing to the middle of next week.
Within this swath of snow (melted) and rain, a general 1 to 2 inches of water can fall.
Farther south, there is the likelihood of a severe weather outbreak, perhaps reaching as far north as northern Kansas and northern Missouri.
Meanwhile, ahead of the big storm next week, a swath of snow will roll across part of North Dakota and the Upper Midwest into Saturday.
