Very mild weather comes to an end today, abruptly so near lake. Rain starts in tonight & could change to wet snow before ending Thursday. pic.twitter.com/3I19zNyK3q— NWS Chicago (@NWSChicago) February 28, 2018
Tricky snow forecast Thur? Difference of ~1 or 2F is cold rain vs wet snow. Snow probably won't stick, but small chance of quick heavy snow! pic.twitter.com/SaXZxXKHMZ— NWS Chicago (@NWSChicago) February 28, 2018
If you're going to be near the lake early this afternoon, be prepared for an abrupt drop in temperatures from the 50s quickly into the 30s! pic.twitter.com/ig6zaD5bF4— NWS Chicago (@NWSChicago) February 28, 2018
Though precip should remain mostly as rain, there is the potential that the heaviest bursts will fall in the form of extremely wet snow Thu. morning mainly north of I-80. Accumulations would generally be under an inch. pic.twitter.com/8JO6JRdh4s— NWS Chicago (@NWSChicago) February 28, 2018
Visible satellite imagery since noon depicts the cold front, enhanced by the lake (pneumonia front), pushing through the Chicago metro. The opaque white over the lake is fog, some dense, & has oozed into shore areas. Allow some extra time if traveling near the shore. #ilwx #inwx pic.twitter.com/W61ZgqcMwh— NWS Chicago (@NWSChicago) February 28, 2018
Rockford, IL tied a record daily high today of 62°. Normal is 39° but normals this time of year are averages of big ranges. The last four Feb 28 dates in #Rockford:— NWS Chicago (@NWSChicago) March 1, 2018
2018: 62° (record daily high)
2017: 61°
2016: 62° (record daily high)
2015: Low of -16° (record daily low)#ilwx
Developing rain will continue overnight with potential on Thu a.m. for a change to a wet snow. This one to three hour changeover is presently most favored in NE IL & far NW IN after 8a, however still fairly high uncertainty. If it snows it likely will be briefly heavy #ilwx #inwx pic.twitter.com/S1dhZlGke5— NWS Chicago (@NWSChicago) March 1, 2018
One year ago today was an early season major tornado event across Illinois. This included two EF-3 tornadoes, one striking Washburn and one Naplate. For more on this event, see: https://t.co/dqPl8TiOag #ilwx pic.twitter.com/HSqcRFwqhF— NWS Chicago (@NWSChicago) March 1, 2018
