A fairly mild but wet weekend is in store for the Chicagoland area. The storm system responsible for producing damaging 100+ mph wind gust out West, will surge northward out of the southern Plains tonight. As it does so, it will gather strength from the Gulf of Mexico. Moisture will expand and increase in intensity as this storm system moves northward tonight.
Areas to the north and west of the low pressure system such as eastern Nebraska, northwest Iowa, southeast Minnesota, western and northern Wisconsin, and the Upper Peninsula of Michigan are under winter storm watches where as much as 8 inches of snow is expected to fall. Areas to the south and east which includes southern Wisconsin, northern Illinois, and northwest Indiana, precipitation will fall mostly if not all in the form of rain.
Here in Chicago, clouds will increase tonight into the morning hours on Saturday. Rain moves in from the south Saturday morning and will fall occasionally throughout the day. Winds will increase from the southwest that will allow for temperatures to approach near the 50 degree mark. The heaviest rainfall will wait until the overnight hours Saturday into Sunday morning.
On Sunday, rain will diminish by the mid afternoon hours as a cold front which will be the leading edge of the coldest airmass of the season passes by. Temperatures will plunge from the lower to mid 40s Sunday afternoon into the 20s overnight.
