February 23-25 Winter Storm Event

A prolonged snow event occurred this past weekend over the northern plains. Snow amounts ranged from 14 inches in Wadena, Minnesota to around 1.5 inches in Bisbee, North Dakota .  The Grand Forks area received 7.1 inches of snow from Saturday through Sunday, while Fargo saw amounts around 5.3 inches.  Many areas saw localized heavier amounts from snow bands, which increased accumulation rates over short distances.  These snow bands are challenging for meteorologists to forecast, and this is one reason why it is so tough to pin down exact snow amounts in a forecast. 

Here is a preliminary snow fall map for this snow event.

These heavy snow bands can produce 1-2 inches per hour snow rates, while areas outside of the snow band receive much less snow.  These events present many challenges to forecasters when dealing with snow amounts. 


A slow moving low pressure area moved out of the central plains Friday night, then into Michigan by Monday morning.  The slow movement of the system allowed moisture to be transported over weak surface low pressure through the weekend, and significant snow fall amounts occurred.
