Strong indications that the first week of March will feature temps well below average across much of the central & eastern U.S. according to @NWSCPC. Our normal highs/lows for early March are lower 40/low to mid 20s, so look for temps more reminiscent of early Jan than early Mar! pic.twitter.com/tZSksHB6yy— NWS Chicago (@NWSChicago) February 20, 2019
Enjoy the quiet weather on Thursday and during the daytime on Friday! Sunshine will return and high temperatures will be in the mid 30s to low 40s. However, it looks to be an active weather pattern this weekend with rain, freezing rain, snow and windy conditions all possible. pic.twitter.com/R4GKdwaObH— NWS Chicago (@NWSChicago) February 20, 2019
Precipitation is mainly freezing drizzle across northern Illinois and northwest Indiana. Farther north, the freezing rain may still be mixed with snow. A glaze to a tenth of an inch of ice is possible on untreated and elevated surfaces. pic.twitter.com/6bRW5EI05S— NWS Chicago (@NWSChicago) February 20, 2019
