WEST MICHIGAN (July 1, 2014) — It took strong to severe storms and the passage of a strong cold, but a sharply cooler and drier air mass is already filtering in to the state.

Dew point temperatures, a measure of moisture in the atmosphere, have dropped from the low 70s to the low 60s. That’s huge! When dew point temperatures reach the low 70s the air outside is very moist, very sticky, very tropical, very humid. It’s a much drier, more comfortable air mass with dew points in the low 60s.

A secondary cold front and some upper level energy will pivot through the Great Lakes on Wednesday. That means a fair amount of cloudiness and perhaps some isolated to widely scattered showers are possible. The extensive clouds will likely hold most high temperatures to the upper 60s/low 70s.

After the front passes, we’re expecting mostly sunny to partly cloudy skies for Thursday and Friday with little/no humidity. The best chance for more unsettled weather with showers and perhaps a few thunderstorms arrives Sunday P.M. and Monday.
