Frost Advisory

Although most rural areas of the Stateline have already seen frost or freezing temperatures, an "official" freeze has yet to happen at the Rockford airport. That could change tonight as I'm forecasting a low of 32 degrees in Rockford. And because some area gardens are still blooming, a frost advisory has been issued by the National Weather Service:

...FROST ADVISORY REMAINS IN EFFECT FROM 1 AM CDT /2 AM EDT/ TO
8 AM CDT /9 AM EDT/ FRIDAY...
