The National Weather Service has issued a Tornado Watch for several counties Wednesday night, as the Chicago area braces for potential storms. 

The Tornado Watch covers McHenry, Kendall, Lake, Kane, Boone, Lee, Ogle and Winnebago counties as well as Kenosha County in Wisconsin.

A Tornado Warning was issued for northwestern McHenry counties as well as southeastern Winnebago and southern Boone counties.

A Severe Thunderstorm Warning was issued for parts of Lasalle, DeKalb and McHenry counties until 11 p.m.

Much of the Chicago area remains under a Wind Advisory into the evening as well, with all inbound flights being held at their origin until 6:15 p.m. due to wind, according to FlightAware.com.

Flights to and from O’Hare were experiencing 30-60 minute delays due to high winds, the airport tweeted at 7:19 p.m.

The Wind Advisory took effect at noon and remains in place until 8 p.m. for most counties, except Lake and McHenry in Illinois, according to the National Weather Service.

Winds of up to 50 mph are possible, the alert warns.

Wednesday started off with partly sunny skies and warm and humid conditions as highs reached into the mid- to upper-80s.

Isolated strong to severe storms are likely by the late afternoon and early evening hours, particularly in far western counties.

Those storms could move toward the city later in the evening, bringing with them damaging winds, large hail and the potential for an isolated tornado.

Any storms that do develop are expected to end by midnight.

Warmer temperatures will linger into Thursday with highs still near 80, but those temps are expected to fall quickly during the late afternoon and evening hours.

By Friday, highs will have dipped back into the low-60s and upper-50s in most areas.

The weekend will see another chance for rain as temps stay in the 60s and 70s.
