Storm Summary for the 27th into the 28th of February, 2024

Record high temperatures ( many cases all time record highs for February) were quickly brought to an end by a strong late February cold front. There were 21 reported tornadoes, mostly EF-0 and EF-1 but there was an EF-2 near Grand Blanc in Geneses County just ahead of the cold front. Temperatures fell around 50 degrees between Tuesday afternoon and Wednesday afternoon over Lower Michigan. There was 6 to 10 inches of snow in upper Michigan and locally 1 to 2 inches of rain in parts of southern Lower Michigan. Winds gusted to 69 mph over western Lake Erie.

Unusually Warm into Friday, then over the next week, the colder air returns over most of the CONUS.

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.

It will be unusually warm till next weekend. Then the cold and snow return. This time the cold will not move out as quickly as it did in January.

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.

Here Is a Summary of our Impressive Winter Storm from January 12th through the 15th

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.

It is looking like December 2023 will end up being in the top 5 warmest Decembers on record across Michigan. This will likely be true not only in Michigan but across most of the northern CONUS.

So far, as of the 16th, December is averaging 6 to 8 degrees above normal across Southern Lower Michigan. Flint is warmest with +7.8, while while Grand Rapids is the least with +5.5. Most other climate sites are between 6 and 7 degrees warmer than normal through the 16th in Michigan. Over northern Michigan Alpena has the least positive departure with +4.1 while Gaylord is +5.9 and Traverse City is +5.1. We are expecting two cold days (Monday and Tuesday) but the rest of December is expected to well above normal. Thus, December 2023 is likely to be in the top 5 warmest on record over most of Lower Michigan.
