Hints of spring: Northern Illinois could see a multi‑day stretch of 50s

Even though Tuesday featured a cool northwesterly wind, it felt nice as the Rockford Airport came in with highs in the upper 40s. That was our third day this month with highs in the 40s. 

 

 

  

We take a small step backward in the temperature department as the colder air from yesterday's frontal passage sits overhead. Still, we can expect afternoon highs to land in the low 40s and since we have an area of high pressure sitting nearby, plenty of sunshine is on the table from start to finish.

 

  

Forecast models show clouds increasing overnight as a very weak system dives into the plains. If there was any chance for precipitation, it would be during the morning hours Thursday and more to the south and west of the Stateline. At this moment, we'll keep a very small chance with skies remaining mostly cloudy as we go into the afternoon. High temperatures should once again peak in the low 40s. 

 

So far in 2026, Rockford has observed three 50° days and they have all occurred in January. Two of them breaking a previous record high. 

 

 

  

We will likely add to that tally this weekend and next week as northern Illinois could see multiple days with highs in the 50s. Ridging over the central plains will supply us with this next batch of milder air, pushing afternoon highs into the 50s possibly Friday, but more than likely over the weekend. Overnight lows will end up closer to Rockford's average highs, dropping into the low 30s Saturday night and Sunday night, then into the upper 30s Monday night.
