The severe weather risk has shifted across portions of south Lake Michigan tonight, with Chicago in the risk area. Behind the upper-level low, there will be enough instability and energy in the atmosphere to spark up isolated severe storms with wind being the primary threat. A few showers and storms will continue overnight, mainly across southwest Michigan.     Rainfall totals won't be all that impressive, but we could pick up on an inch or so in the heaviest of downpours. Temperatures will drop behind this front as well, back down into the 50s for the day on Monday! Feeling certainly like fall.
