The last time any significant measurable rain fell in Rockford was back
on July 18th when 1.66 inches came down. Since then, the rain has been
few and far between for much of northern Illinois and southern
Wisconsin. That will change early Monday morning as a cold front begins
to move closer to the Stateline.
Skies will remain partly to mostly cloudy through much of Sunday evening
as thunderstorms move across Minnesota and northwest Wisconsin and rain
showers move through Iowa. Much of the forcing in the atmosphere will
be centered over the Upper Midwest through Monday morning, giving a
better chance for thunderstorms north of the Stateline.
The rain falling over Iowa Sunday evening will hold together long enough
and is expected to move into the Stateline after 2am/3am Monday
morning. It likely won't be much, between 0.20 and 0.40 inches, but
definitely needed as the ground and fields have become dry. In fact,
parts of northwest and west-central Illinois have been placed under
'abnormally dry' conditions from the National Drought Mitigation Center.
It seems like just a few months ago we couldn't turn the rainfall
faucet off.
Following Monday's rain chance skies will turn dry once again as high
pressure anchors itself over much of the Great Lakes and Midwest.
Minimal chances for rain are expected this week with high temperatures
in the low to mid 80s and overnight lows dipping into the 50s.
