Feeling the Difference

What a difference a week makes! There is quite a measurable change from high temperatures last week compared to this week. Last Monday featured about an inch of rain and thunderstorms, and highs that climbed into the low 50's. Rockford's official high was 54°, but the pattern aloft has been changing. Through late Sunday and into Monday, a steep upper trough or dip in the jet stream is helping to tug in colder Canadian air. Behind the cold front, highs today will only climb a few degrees today into the upper 20's. The forecast high of 28° is 26° colder compared to last week's high.

There is another small warm up this week, by midweek highs will climb into the 40's. Unfortunately that won't last, temperatures will fall back into the 30's and 20's by the end of the week.
