Overview
A strong surface low pressure system and upper level trough ejected out of the Southern Rockies and transitioned east-northeast across the Central and Southern Plains from February 22 to 24, 2019. This system caused widespread wintry precipitation over the central CONUS, especially over central and southern parts of Iowa on February 23rd. Snow developed across western to northern Iowa on the evening of the 23rd and continued into the overnight hours towards the morning of the 24th. Widespread snowfall amounts of 5 to 15 inches fell across the northwest half of Iowa before ending by the afternoon of the 24th. In addition to the falling snow, very strong northwest winds of 30 to 45 mph caused widespread blizzard conditions from the late evening of the 23rd through much of the 24th. The snow pack prior to the storm was already a foot to nearly two feet over portions of western and northern Iowa, resulting the additional snow to mainly accumulate in drifts. |

Radar:
Modeled MRMS precipitation type | Modeled MRMS reflectivity |
This is the actual radar loop of the entire event. When the radar seems to "slow down" is when we switched the radar into a different mode and gathered data more frequently. You can see that the Des Moines Metro area was near the pivot point of the heavy snow band to the west and north.
