Cold front ends record 7th day of 70-degree temps

Chicago storm

CHICAGO(WBBM NEWSRADIO) -- Chicago will see its last day of unseasonably warm weather Tuesday as temperatures fall in the afternoon, ushering in thunderstorms, dangerous wind gusts, and potential tornadoes.

"It remains windy and warm at this hour [10:15 a.m.]. Temperatures are close to 70 degrees. We will gain a few degrees to a high of 74. Towards evening we will have to dodge a shower or thunderstorm. There could be some gusty winds with those thunderstorms this evening, then the cold front with move through and it will start to clear. By morning we are all the way down to 35," Accuweather meteorologist Joe Lundberg said.

The impending cold front will end a record-breaking seven straight days of 70-plus-degree November weather, blowing past the previous five-straight days of similar weather in 1953.

According to the National Weather Service, Tuesday's change is not expected until the evening hours. Wind gusts of 40+ mph are expected to start in the afternoon and continue through the evening, with the chance of a shower or thunderstorm in the late afternoon early evening.

The National Weather Service said thunderstorms will move quickly late Tuesday afternoon into the early evening and could create damaging wind gusts up to 60 mph and a few tornadoes. But because the storms are fast moving, the threat will be brief, the weather service said, lasting around one to two hours. Storms are expected between 3 p.m. to 9 p.m. moving west to east.

After the storms pass, gusts up to 45 mph will continue until midnight as temperatures keep dropping.

Tornadoes are possible among the storms throughout the entire metro area, but the risk is highest in the west and north suburbs — from Joliet past O’Hare Airport to Lake County, National Weather Service meteorologist Todd Kluber said.

Meanwhile, temperatures will plummet overnight, making Wednesday morning feel between 40 and 50 degrees cooler than Tuesday, Kluber said.

Accuweather meteorologist Joe Lundberg said Veteran's Day will be nice and sunny, but much cooler with a high only near 50. Sunshine for Thursday, with a high near 55. Friday will be a chillier day with sunshine and clouds with a high of 45, and then expect more rain Saturday with a high of 47.
