Spring is the time of year where strong low pressure systems can form and produce warm weather and severe storms on their southern end with cold and heavy snow to the north. This type of a setup is likely the end of the work week.
Temperatures are well into the 50s and 60s right now across most of the path of the storm. The beginning of the system is in the Pacific Ocean right now getting ready to move into the Pacific Northwest. It will dip down into California Wednesday and then eject out of the Rockies on Thursday before strengthening Friday into the heavy snow storm and severe weather event.
The energy shown above on the satellite image will look a lot more impressive in 48 hours.
Snow, plus blowing and drifting will cause issues on the roads from the Rocky Mountains to northern Wisconsin, a large part of Minnesota and northern Michigan. Snow will develop Wednesday night across the Rocky Mountains and spread eastward. The true blizzard conditions with winds over 35mph and visibility below 1/4 mile for at least three hours will be possible from northern Iowa through the Upper Peninsula of Michigan.
Most of the path of snow will have at least a few fresh inches. There is the possibility for 6-12 inches from southern Minnesota, northern Wisconsin and the U.P. of Michigan. There could even be a corridor of more than one foot of snow where the best lift dynamics are about 100 miles north of the low pressure track. The highest totals could be up around 20 inches in localized areas. Where exactly that sets up would mean big travel issues.
The cities that will see the worst conditions of the storm as of now look to be: Sioux Falls SD, Eau Claire WI, Minneapolis, Cokato and Rochester, Minnesota; Park Falls and Marquette, Michigan.
Stay tuned for more coverage on this storm from the warm and stormy side to the snowy and blizzardy side.
