Overview
A strong, multifaceted storm system tracked through the Midwest on March 15th and 16th, 2026, bringing a variety of weather to the region.
In the local area, heavy rainfall and thunderstorms occurred during the afternoon and evening of the 15th. Multiple instances of flooding occurred in the Chicago metro, where rainfall totals largely ranged from 1.00" to 2.50". A few thunderstorms also grew strong enough to produce localized damaging winds.
O'Hare Airport observed a liquid precipitation total of 1.83" over the course of the event. 1.76" of this precipitation occurred on the 15th, breaking Chicago's daily record precipitation total for March 15th (previously 1.43" set back in 1943).
The rain changed over to a brief wintry mix and then a steady snow during the late evening as air temperatures cooled rapidly on the backside of the system. The steadiest snow continued through the night and into the morning of the 16th before snowfall rates and coverage diminished. Snowfall totals as high as 8" were observed in portions of interior northern Illinois.
Official snowfall totals for this event:
Rockford: 5.7"
Chicago (O'Hare Airport): 1.3"
3 miles southwest of Midway Airport: 1.6"
Romeoville (NWS Chicago): 2.5"
Strong winds also occurred on both days, with southerly wind gusts to 50 mph observed in some areas on the 15th and northwesterly wind gusts to 45 mph observed across most areas on the 16th. The strong winds on the 16th led to blowing snow and near-blizzard conditions in some parts of interior northern Illinois.
Scattered, locally heavy wind-whipped snow showers continued through much of the 16th all the way through the early morning hours of March 17th, resulting in locally hazardous travel in some areas.
At the NWS Chicago office in Romeoville, one razor-thin snow band dropped 2.6" of snow in about one hour during the early morning hours of March 17th!
