Extended Outlook

Chicago forecast highs and departure from normal

The extended outlook calls for a dry week ahead with temps in the seasonal 60s and Monday in the mid to low 70s.

Partly cloudy skies for most of the week ahead.

Our coolest day looks like Wednesday with a high of 62. Rain looks to return by next weekend. 

High temperatures next nine days (Blend of Models)

Expect a brief shot of cooler air for the Midwest, Great Lakes, and Northeast by mid-next week, but warmth returns following a brief downturn. It’s a very progressive pattern. 

Forecast average temperature anomaly: October 10 through 16

Cooler air across the eastern U.S. and Mid-Atlantic plus California, Nevada, Oregon and Washington. Well above normal across the southern Plains.  

Forecast average temperature anomaly: October 17 through 23

Significant warmth relative to normal across Texas and the central U.S. while it remains unusually cool across the western U.S. including California. 

Strong coastal low forecast to affect the U.S. East Coast into early next week. Coastal flooding, gusty winds, and heavy rain are expected for some locations.  

Peak wind gust potential 

40-60 mph wind gusts are possible over a long stretch of coastline, but the track of the low pressure could spare the worst of the impacts—as the backside of the low is likely to remain offshore.
