A disturbance over Iowa this afternoon has moved through northern Illinois. It generated a generous area of rain across northern Illinois during the supper hours. 0.64" of rainfall was recorded at the Rockford International Airport. That disturbance has moved off to the east, and so has most of the rain. However, the cool front is still to our northwest, and some scattered showers and thunderstorms are still possible overnight as the front approaches and moves into the area. Widely scattered showers and thunderstorms will be possible on Monday afternoon. It will be dry by Tuesday. The jet stream will shift far off to the north into Canada by Wednesday, and high pressure will build in across the Stateline aloft along with a southerly wind, and that will cause temperatures to get hot...right around 90 degrees. The next chance of thunderstorms will be on Wednesday night continuing into Thursday as the next front approaches, and passes through the area. Despite the front moving through, there will be very little cooling with high pressure aloft continuing it's hold on the area. The extended forecast is iffy because of the possibility of some disturbances riding in the westerlies along the northern edge to the hot high pressure ridge to our south. It will be very warm with highs in the upper 80's on Friday, Saturday, and Sunday.
