CHICAGO — It's the coldest Valentine's Day morning in Chicago in 77 years, according to the National Weather Service reports.

The mercury got down to -2 at O'Hare Airport Friday morning. It's the first time this winter that a subzero temperature was recorded O'Hare.

Back in 1943, the National Weather Service recorded a low temperature of -3 at O'Hare. The coldest Valentine's Day ever in Chicago was back in 1905 — the coldest low recorded that day was -11!

A Wind Chill Advisory for dangerous wind chills as low as -15 to -25-degrees across northeast Illinois remains in effect until 10 a.m. Friday.

If outside for any length of time this morning, bundle-up and cover exposed skin on your face and hands – frostbite could occur within 30 minutes on exposure.

Still under the influence of Arctic high pressure, there won’t be much of a temperature rebound today, even with the expected abundant sunshine – highs forecast to reach only the middle teens. A shift to southerly winds will signal the start of a “warming trend” later this afternoon/evening with highs reaching into the 30s Saturday along with the prospect of some light snow.
