Sunshine & Warm Temperatures

Skies will be sunny to mostly sunny today. High pressure over the northern plains has taken control of Stateline weather.  Despite the fact that winds will pick up to 10 to 15 mph from the northwest this afternoon, the temperature will still rise into the upper 80's.  However, there will be a noticeable drop in humidity as the day goes on with dew points dropping back into the middle 50's by late afternoon.  Tonight will be clear and cooler with the ridge of high pressure remaining to the west of the area.  The overnight low will be in the upper 50's with northerly winds become near calm overnight.  There is a chance of some patchy fog developing late tonight.  By early Tuesday morning the high will be over Lake Superior with a ridge southward right through the Stateline.  It will be sunny with a high in the middle 80's on Tuesday.  The wind will be light and variable, and the humidity... comfortable.  By Wednesday evening the high will be situated over the door peninsula with the ridge maintaining itself right across northern Illinois, so it will be clear and comfortable again with a low in the upper 50's.  By Wednesday morning the high will be over Michigan, and the ridge will still be with us.  It will be sunny again, and the temperatures will be edging up toward 90 degrees.  On Thursday morning the high will be over Pennsylvania, and the ridge will still be across our area.  It will be hot with a high in the low 90's with increasing humidity levels.  It will still be hot on Friday under mostly sunny skies.  Humidity levels will continue to rise as the remnants of Isaac move up the Mississippi River.  Friday's high temperature is likely to be in the low 90's again.  On Saturday Isaac remnants may move into southern Illinois pulling gulf moisture northward into the Stateline.  That will set the stage for possible thunderstorm development.  Temperatures will fall off a few degrees into the middle 80's on Saturday afternoon because of increased humidity, more clouds, and possibly rain cooled air associated with thunderstorms.  It will be partly sunny on Sunday with a high in the middle 80's.
