Winds will turn out of the south on Friday which will usher warmer air into the region. Temperatures are expected to climb into the 50's or lower 60's on Saturday and Sunday. Rain will move into the region by late Saturday and continue through Monday as a strong storm system moves northeast across Missouri and Illinois. The rain may mix with or change over to snow early next week as the system moves off to the east. (Please visit http://weather.gov/lsx for more information.)
