Thru early next week, generally close to seasonable & therefore pleasant 50s-60s inland compared to winter-like cold much of this April. Unfortunately for areas near #LakeMichigan, daily lake breezes will keep it cool, w/primarily 40s for highs along immediate shore. #ilwx #inwx pic.twitter.com/JEBWTuqywk— NWS Chicago (@NWSChicago) April 20, 2018
Mild temperatures expected over the next five days, but cooler near the lake due to onshore flow. No snow expected! #Spring #ILWX #INWX pic.twitter.com/JpAolTZAIT— NWS Chicago (@NWSChicago) April 20, 2018
Median last spring freeze (32°F or lower) date ranges for #ILWX & #INWX. Across nrn & central IL & NW IN, median last freeze falls within April 11-30 (majority between 4/21-4/30). There are a few sites w/median last spring freeze between May 1-10. Maps created by @MidwestClimate pic.twitter.com/MombCLSulb— NWS Chicago (@NWSChicago) April 20, 2018
Finally some warmer air for some parts of the north is ahead: https://t.co/7ZMtcDpzAc pic.twitter.com/ZX8SmfAHeS— The Weather Channel (@weatherchannel) April 21, 2018
Just released: Our May-July temperature outlook suggests some lingering cool risks into the summer in parts of the Midwest and East. https://t.co/4kRl87c8d9 pic.twitter.com/AdFknBXefc— The Weather Channel (@weatherchannel) April 20, 2018
