Chicago Experiences Extreme Temperature Swing: What to Expect
Chicagoans can finally trade in their heavy winter coats for lighter jackets, at least for a few days. The highly anticipated warmup has arrived, with temperatures soaring to the mid-to-upper 50s on Monday. This dramatic shift is a stark contrast to the wind chills that plummeted 20 degrees below zero earlier in the week.
The Science Behind the Swing: What Causes Extreme Temperature Shifts
Local meteorologists have weighed in on the phenomenon. National Weather Service meteorologist Brett Borchardt explains that such temperature swings are not uncommon for this time of year. "We see these fluctuations between warm and chilly temperatures quite often around this time," he said. Historically, Chicago has experienced highs in the 60s during mid-February, making this week’s abrupt change a relatively typical occurrence.
Historical Context: Last Week’s Record-Breaking Cold
Last week’s temperatures were far from average, leaving many Chicagoans shivering. According to WGN-TV weather producer Bill Snyder, the average temperature last week was 16 degrees below normal. This anomaly marked it as the sixth coldest week in the past 97 years for Chicago. The record high temperature for this date, set in 1930, is 64 degrees. The average high for February 24 is 39 degrees, a milestone that Chicago exceeded before 7 a.m. Monday morning, showcasing the stark contrast in weather conditions.
| Date | High Temp (°F) | Low Temp (°F) | Record High (°F) |
|---|---|---|---|
| February 17 | 20 | -5 | 54 |
| February 24 | 55 | 30 | 64 |
Looking ahead, Tuesday’s temperatures are expected to dip back into the upper 40s to low 50s, but a rebound into the mid-50s is anticipated by Wednesday. This warmer-than-average stretch will likely end as we approach the weekend, with highs returning to more normal readings in the upper 30s to low 40s.
