A warm start to the week

A weak cool front will pass through the Stateline overnight virtually unnoticed with just a windshift.  A severe thunderstorm developed over eastern Iowa early this evening causing 85 mph wind gusts at the Dubuque airport. It then moved southeast moving across Jo Daviess county causing 70 mph wind gusts near Hanover. It diminshed in intensity as it continued southeast across extreme southwestern Stephenson and northeastern Carroll county. Another thunderstorm developed, and caused brief downpours and gusty winds in the Rockford after 7:30 pm. The threat of thunderstorms is now over, and showers are falling apart. Other than that, skies will be mostly clear overnight with a light westerly wind. High pressure will be in complete control on Monday along with sunshine, and warm temperatures in the upper 70's. A system may graze the western sections of northern Illinois on Tuesday with some scattered showers, and possibly a thunderstorm. A system moving thru the area on Wednesday and Thursday will bring more widespread rain. The best chance of significant rain will be on Wednesday night into Thursday morning.  Friday with be partly sunny and pleasant with an afternoon high in the low 70's.  Another fast moving system with drop in from the northwest, and there will be a slight risk of showers and thunderstorms again on Saturday and Sunday.
