No doubt the winds have been strong Thursday, but peak wind gusts Friday could reach 50 mph late morning and early afternoon.
And because of that a Wind Advisory has been issued for Northern Illinois and Southern Wisconsin beginning Friday morning and lasting until Friday afternoon. Sustained winds 25-35 mph from the west/southwest will gust between 40-45 mph Friday.
Winds will ease a little by Friday evening, but still remain gusty into Saturday. Temperatures Saturday will warm into the low 50's as well.
