Rain Approaching the Stateline at 11 pm Thursday Night

After a day that saw temperatures soar to 89 degrees at the Greater Rockford Airport, and upper 80's throughout north central Illinois, temperatures are holding in the upper 70's in areas east of where rain is falling.  A strong southwesterly wind is blowing 20 to 30 mph with higher gusts bringing dew points well into the 60's along the Mississippi River.  The low level jet between 1 and 2 thousand feet is clipping along between 55 and 70 mph.  As the showers, and possibly a few storms move into the area during the next few hours, it is possible that some of those very strong winds aloft will be transported down to the ground causing the wind to gust as high as 60 mph for a brief period.  The front is anticipated to move through before daybreak shifting the winds to the west.  Don't expect the winds to let up though.  The will be westerly on Friday between 15 and 30 mph with gusts above 35 mph in the mid day hours.  A few rain showers may linger into the early morning, but the clouds will break, becoming partly cloudy by mid day, and mostly sunny towards sunset.  Temperatures will hold in the 60's for most of the day, but drop back in the upper 50's shortly after sunset.  With mostly clear skies on Friday night, the winds will diminish, and temperatures will fall into the middle 40's.  Saturday will be another cool day with highs in the 60's, and a disturbance moving eastward across the plains may generate a few showers on Saturday afternoon.  Showers will be more likely on Saturday night.  Sunday will be partly cloudy and continued cool with a high in the upper 60's.
