CHICAGO (CBS) — Monday is the first day of meteorological summer, but it feels more like the first day of March.
While the summer solstice is still about three weeks away, weather folks keep records based on the quarterly calendar, which is why they consider today is the first day of summer.
However, temperatures started the day in the 40s in Chicago under overcast skies.
The sun is expected to emerge around lunchtime and temperatures are expected to rise into the upper 50s or low 60s.
However, that is about 15 degrees below the normal for June 1.
Better days are ahead, with a gradual warming trend all week with highs in the 70s and mostly sunny skies.
