.DISCUSSION...High pressure will shift east today into tonight, but
conditions should remain dry through this afternoon. Minimum RH
values will dip into the 30-40 percent range as high temperatures
reach the 60s. An approaching warm front associated with a low
pressure system over the Midwest will bring the next chance for rain
tonight. Showers and a chance of thunderstorms are then expected on
Wednesday as the low pressure system lifts across the northern Great
Lakes and drives a cold front across southern Michigan.
