Thursday and Thursday Night …
No Weather Hazards expected…
This Weather Outlook is for portions of North Central Illinois … Northeast Illinois and Northwest Indiana.
Seasonably moist air mass is streaming north toward the area early this morning with a few showers more likely southeast of I-55.
A cold front will move across the area this evening bringing an end to the showers late afternoon and early evening. Not much chance of significant precipitation, but rain is mostly likely from 2:00 p.m. to 4:00 p.m. Thanksgiving afternoon. The air mass behind the cold front is of Pacific origin, so the air moving in is drier and not much cooler. With more sunshine, Friday temps might be warmer than Thursday, even though some forecasts indicated a high temp slightly lower or about the same. We might see mid 50s instead 49 or 50.
Third consecutive morning low above freezing forecast for O’Hare on Friday morning.

Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
542 AM CST Thu Nov 24 2022
.SHORT TERM… Issued at 213 AM CST Thu Nov 24 2022
Seasonably moist air mass is streaming north toward the area early this morning with a few showers accompanying the moisture return and likely aided by southern stream short wave passing south of the area this morning. Have introduced some small precip chances this morning with this initial band of widely scattered showers. More showers are expected later this afternoon as northern stream trough and associated cold front approach. Deeper moisture should reside over our southeastern CWA, mainly southeast of I-55, which is where showers are forecast to blossom as forcing from the approaching wave encounters this moisture. Northwest of I-55, particularly out toward northwest IL the best chance of showers looks to be this morning with the lead wave and theta-e advection and then likely dry this afternoon and tonight.
Cold front will move across the area this evening bringing an end to the showers by mid-late evening across our northwest Indiana Counties. Air mass behind the front is of Pacific origin, so drier and not much cooler. In fact, with more sunshine Friday temps will probably end up warmer than they will be today. Trended highs warmer than guidance toward the 925mb climo MaxT, which is generally lower 50s. Given the expected full sunshine and warm air advection it is quite possible it could end up mostly in the mid 50s.
