What makes this more striking is that over the past 30 years, the last week of January and the first two weeks of February are the coldest weeks of the entire year. The mean of 37.2 degrees in Grand Rapids would be normal for the 20th of March (using the 1991-2020 normal).





This past 15 days ( Jan. 23- Feb. 7) in Grand Rapids, Michigan were the warmest on record (34.8F) that exceeded the 34.7F for the 15 days ending on January 6th 2012.
















































The bottom line is it will be very warm, relative to normal until around Valentine’s Day, the it will get cold across most of the central and eastern CONUS with a significant amount of snow over the Great Lakes and New England.
Record warmest December for the CONUS (1st out 129 years)
Precipitation was near normal (70th out of 129 years)
Snowfall was well below normal across the CONUS
A strong El Nino Continued (based on ONI data from CPC)











Does the cold and snowy weather come back?



































Over Michigan, November and December featured well below normal snowfall. The first 2 1/2 weeks of January seem to be making up some of that deficit. Over the rest of the CONUS, seasonal snowfall mostly remains below normal.







A rapidly deepening storm tracked Texas on Thursday afternoon to the northern Great Lakes by Saturday morning. The storm brought 1 to 2 feet of snow from Nebraska, across Iowa, Wisconsin then into Michigan. Strong winds accompanied the storm then the coldest air in several years followed the storm with dangerously cold wind chills over most of the Northern and Central Midwest. That cold air caused heavy lake effect snow in Michigan, near Buffalo New York and over the Tug Hill Plateau in the Adirondack Mountains, down wind of Lake Ontario.
