After record heat in the High Plains this week, an incoming cold front and low pressure system will work together to lower temperatures along with the potential for snow and rain across the Upper Midwest and Great Lakes. Highs drop from near 60 in North Dakota (about 25° above average) to the 30s through the weekend.
There is a discrepancy, as is often the case with the spring months, about how much snow we could see in the Upper Midwest and exactly where it will be. The Baron model is dropping a range of snow in SE Minnesota, northern Wisconsin and UP Michigan, while the GFS model is trending a bit further south with snow reaching northern Iowa. Bottom line, we are a few days out, so this forecast will be accurate.
Moisture moves out of the Rockies and into the High Plains of the Dakotas, Iowa and Nebraska on Wednesday, but temperatures will be too warm to support snowfall. Instead, there is one severe weather threat to the central plains. As temperatures drop and the storm system moves into the Upper Midwest, rain will turn to snow by Thursday afternoon and overnight. By Friday morning all rain and snow chances will also affect the northern Great Lakes region with an ice corridor.
