Clearing skies occurred following Thursday evening's round of
scattered showers, allowing pockets of dense fog to form. As a
precaution, the National Weather Service has extended the Dense Fog
Advisory for Boone, DeKalb, and McHenry counties in N. Illinois until
7AM . For Rock and Walworth counties in S. Wisconsin, it will expire at
5AM.
Cloud cover stays put, especially for areas north of interstate 88 as a
second disturbance slides into the western Great Lakes. This could spell
a mixture of scattered sprinkles and light flurries up until midday,
with sprinkle chances lasting into the afternoon. Also in the mix will
be a few peeks of sun, though a rather gusty northwesterly
wind will create
challenges for our warm up. Afternoon highs will be limited to the mid
40s. That, combined with 25-35 mph gusts
will leave wind chills in the low 30s.
A
stronger storm system sliding in on Friday will put our temperatures on a
wild ride into the weekend. Winds Friday morning will be out of the
southwest, turning to the northwest by the afternoon following the passage of a strong cold front.
At times, gusts
could be as high as 45 mph, allowing afternoon highs to peak in the mid
50s. This would mark the 4th time this week in which the Rockford Airport has
registered a high in the 50s. Colder air funneling in on the cold front's
backside will help tumble temperatures for the first weekend of March and meteorological spring. Though both Saturday
and Sunday feature a good deal of sun, afternoon highs will be limited to the 30s.
