Fabulous Weather on Monday

A weak cool front is pushing in from the west tonight. A very strong upper disturbance moved across Wisconsin this evening, and was able to generate a squall line of thunderstorms with small hail that moved across the Stateline around 10 pm. The line is moving east to southeast at 45 mph, and will be well to the east of the area by midnight. Skies will become partly cloudy, and then mostly clear later tonight. Monday will be mostly sunny and pleasant with a high in the middle 60's. The next system to affect the Stateline will begin developing over eastern Wyoming by the supper hour on Monday, and it will pull a warm front up across northern Illinois by Tuesday morning as the low moves to southeast South Dakota by 6 am on Tuesday. There may be some showers and thunderstorms on Tuesday as the low moves to near Dubuque, Iowa by the supper hour.  Temperatures will be mild with a high in the upper 60's.  In fact, there is potential for  temperatures in the 70's across the Stateline if the low takes a track further to the north..  The best chance for thunderstorms will be during the afternoon on Tuesday in advance of a cold front dropping southwest from the low all the way down into the Texas panhandle.  The cold front will move across the area on Tuesday night, and it will be breezy and much cooler on Wednesday with highs only in the low 50's along with mostly cloudy skies and a chance of showers.  Thursday will be partly cloudy, and the rest of the week will be sunny to mostly sunny and chilly with highs only in the low 50's and lows in the low 30's.
