After a prolonged period of sub-freezing temperatures, the Chicago area is poised for a dramatic and potentially record-breaking warm spell. Residents are bracing for conditions more typical of spring than mid-February, with temperatures expected to climb sharply in the coming days.
The shift began on Sunday, , with a dense fog advisory issued by the National Weather Service. However, as the day progressed, the fog was expected to dissipate, giving way to mostly clear skies and a rapid temperature increase. Forecast models predicted highs in the mid-to-upper 50s, with some areas potentially reaching 60 degrees.
While Sunday’s temperatures weren’t anticipated to surpass the record high of 69 degrees for the date, set in , Monday is expected to bring a new milestone. Temperatures are forecast to rise into the low-to-mid 60s, threatening the February 16th record of 58 degrees, established in .
The warmth isn’t expected to be a one-day event. Tuesday will see a slight dip into the 50s, but Wednesday could be the warmest day of the week, with readings potentially reaching the mid-60s. Although unlikely to break the record of 70 degrees set during a heat wave in , the unseasonable temperatures are a welcome change for many.
This sudden shift follows a particularly frigid stretch for the Chicago area. According to NBC 5 Storm Team Meteorologist Kevin Jeanes, the region endured its longest consecutive stretch of sub-freezing weather in nearly 20 years, with 17 consecutive days below 32 degrees as of . That streak was expected to potentially last until Friday, potentially reaching 20 days below freezing, surpassing the 22-day streak of the winter of .
However, the reprieve from the cold will be temporary. A weather system is expected to move through the area on Thursday night and into Friday, bringing with it chances of rain or wet snow. Temperatures will fall sharply, dropping from the 50s on Thursday to the 30s on Saturday and Sunday.
Despite the return of colder temperatures, long-range forecasts from the Climate Prediction Center suggest that above-average temperatures could return to close out February. This raises questions about the broader implications of these fluctuating temperatures for the region’s economy and infrastructure.
The rapid warming trend is particularly notable given the recent experience of sub-freezing temperatures. The Chicago area has been in a deep freeze, but the forecast offers hope for a change. The potential for record warmth highlights the increasing variability in weather patterns, a trend that has implications for various sectors.
For the agricultural sector, an early warm-up could potentially impact planting schedules and crop development. While a prolonged warm spell could offer a head start, a subsequent return to freezing temperatures could damage vulnerable crops. Infrastructure, too, could be affected. Repeated freeze-thaw cycles can exacerbate existing damage to roads and bridges, increasing maintenance costs.
The impact on energy demand is also significant. The recent cold snap led to increased demand for heating, putting a strain on energy resources. The anticipated warm-up will likely reduce demand, potentially easing pressure on the energy grid. However, the fluctuating temperatures also create challenges for energy providers in managing supply and demand.
The dramatic shift in weather also underscores the broader context of climate change. While individual weather events cannot be directly attributed to climate change, the increasing frequency of extreme weather events – both cold snaps and unseasonable warm spells – is consistent with climate models. The Midwest has experienced notable temperature fluctuations in recent years, aligning with broader global warming patterns.
Alicia Roman, NBC 5 Storm Team Meteorologist, noted that the current warming trend offers a glimpse into the changing seasonal patterns in the Midwest. The frequency and intensity of these warm spells in February are drawing increased attention from climate scientists.

While the unseasonable warmth is a welcome change for many, it’s important to remain prepared for the return of colder temperatures later in the week.
