A gradually clearing sky will allow overnight lows to drop into the upper 30s inland and lower 40s near the lake.

Monday will be a nice day with highs in the mid to upper 60s lakeside, and low to mid 70s inland. Highs clouds will be around much of the day, leading to a hazy sunshine.

Tuesday we will ride a temperature rollercoaster! Temperatures will warm into the mid and upper 70s by early afternoon, but winds will quickly turn out of the northeast off Lake Michigan, bringing a dramatic temperature drop... what we call a pneumonia front. (The temperature has to drop 16-degrees in one hour to be officially considered a pneumonia front.) As the front moves through, temperatures will quickly cool into the 50s, and it will stay cool through the evening. As the front moves in, we may also see a few showers or thundershowers take off.

It will be another cool start on Wednesday morning, with some inland lows in the upper 30s possible. Highs will only make it into the upper 50s and lower 60s on Wednesday following the frontal system.
