Current Weather Conditions

The current weather conditions are a mix of sun and clouds, with a high pressure system over western Wisconsin bringing a northeasterly wind into Chicago. This could help initiate a few sprinkles near the lake.

An area of high pressure over western Wisconsin will bring a northeasterly wind into Chicago and could help initiate a few sprinkles near the lake.

The Next Few Hours

FRIDAY NIGHT: Cloudy this evening with perhaps a brief light shower or a few sprinkles. Partial clearing overnight. Winds: West shifting north 5-10 mph. Low: 48.

We open the second weekend of October with a mix of sun and clouds.

Saturday day planner

We begin the day in the lower 50s, noticeably milder than some recent mornings, and warm into the middle 60s which is similar to Friday’s conditions.

Saturday area highs

Northeast winds off the lake will keep temperatures primarily in the 60s, but a few far west/southwest suburbs may get close to 70-degrees.

Saturday sunburn forecast

Saturday U.S. highs

Lower 48 average rather comfortable around 71-degrees—-summer-level heat lingers in Texas and portions of Arizona where 90s will cover about 20 million U.S. residents.

Much cooler weekend

When you take the daytime high and overnight low and average it out, this coming weekend will average more than 17-degrees cooler than a week ago, but much more typical for early to mid-October.

Extended Outlook

Bank of America Chicago Marathon forecast

Runners will have ideal conditions for the marathon. Expect clear skies and temperatures in the lower 50s at the start of the race, warming into the middle 60s by its completion with light east/southeast winds.

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.
