During the first 10 days of October almost four inches of rain fell in Rockford, pushing us well above the monthly rainfall average. But the last week has been just the opposite, chilly and dry. Within the last seven days, less than a tenth of an inch of rain has fallen.
The dry stretch will continue for another day (Thursday) before a small chance for rain returns by mid-morning Friday. The atmosphere has been very dry over the last week as low pressure systems have been moving in from Canada and Gulf moisture blocked to the south. So even as moisture increases over northern Illinois and southern Wisconsin late Thursday night and Friday, the rain that comes down (if any) should remain fairly light.
A strong cold front will pass Friday night followed by another cold front Saturday. Scattered showers are likely Saturday afternoon, with light snow possible further north. But the drier pattern continues into next week with temperatures staying below average.
