National Weather Service Chicago/Romeoville, IL

.SHORT TERM… Issued at 242 AM CST Mon Jan 30 2023

Through Tuesday…

Expecting the light snow/flurries north of I-80 and freezing drizzle and light snow south of I-80 to end by around sunrise this morning as shortwave trough responsible for this precip exits stage right. Planning to monitor radar/observational trends the next few hours and may be able to clear all or portions of the winter wx advisory a little early.

Cold air advection today should keep temps from rebounding much from the morning lows. The incoming arctic air mass is actually pretty dry, so fairly confident that low clouds/stratus will clear out during the day today.

Other than perhaps some passing filaments of thin mid level clouds, tonight should be clear and very cold. Surface high moving into the region should allow for winds to become light and variable. It really looks like tonight will be an ideal setup for strong radiational cooling, particularly over the fresh dee Psnowpack closer to the WI border and across interior northern IL. ECMWF and GFS 2m temps drop temps over the fresh snowpack into the teens below zero. That is quite a bit colder than some of the other guidance, but seems quite reasonable, so adjusted temps downward tonight, particularly over the deeper snow.

Winds expected to remain 5 mph or less where temps bottom out, so not planning any wind chills headlines. Even without the wind, the main forecast message for tonight is bitterly cold temps. It will remain very cold Tuesday, but as a consolation prize, at least skies should be mostly sunny.
