Winter Storm Selene Timing
- Daytime: A long swath of states from Wyoming and Colorado eastward to Michigan and Upstate New York could see snow or a rain/snow mix. In the Plains, any rain/snow mix will be changing to all snow.
- Night: Snow or rain changing to snow continues from parts of Nebraska and northern Kansas to southeast South Dakota, Iowa, southern Minnesota, Wisconsin and Michigan. A band of freezing rain is expected in northern Iowa, southern Wisconsin and Lower Michigan. Some snow or a mixture of rain and snow may continue as far east as Upstate New York and northern New England.
Gusty winds may accompany the snow leading to reduced visibility and treacherous travel conditions in the Upper Midwest and Plains. Wind gusts up to 55 mph are possible on the Plains of eastern Colorado, leading to blizzard conditions.
- Snow or freezing rain is expected from the upper Mississippi Valley and Great Lakes into western, central and Upstate New York and northern New England Thursday.
- Strong winds will continue to cause reduced visibility and hazardous travel conditions to the north and northwest of where the low tracks in the Midwest.
Wintry weather may linger in northern New England into Friday.
It's not unusual to see snow after the spring equinox in many of the areas that could see accumulating snow this week. For example, Minneapolis-St. Paul averages about 5 inches of snow annually from March 21 through April. For parts of the northern/central Rockies and the adjacent High Plains, April is actually the snowiest month of the year, on average.
In fact, one-foot-plus March snowfalls are no stranger to the mythical "frozen tundra" of Green Bay, Wisconsin.
The name Selene comes from Greek mythology meaning goddess of the moon.
