When will northern Illinois see 80° weather again?

For those wanting this cooler than average stretch to come to a close, the light at the end of the tunnel is much closer than you think. 

After Rockford peaked in the mid 60s Wednesday temperatures will make the climb back into the low 70s today. The climb to the 80° mark however doesn't begin until Friday as highs peak in the upper 70s. We can expect similar warmth this weekend before the thermometer FINALLY eclipses the 80° mark next week, just in time for the start of June. 

Now, its not out of the question that Friday or Sunday could become our next 80° day since temperatures will wind up very close to that mark. 

Saturday has a question mark, a backdoor cold front that slides through shortly after sunrise. This will limit highs closer to the mid 70s.
