Fall-like drop in humidity forecast to last into weekend

A fall-like drop in humidity is forecast to arrive Wednesday and last into the weekend.

Dew points are forecast to drop into the 50s -- and even the 40s, possibly, on Wednesday -- for that stretch. Those levels are more common for September or October.

The dew point is a measurement of the temperature at which moisture in the air would condense into liquid on surfaces like grass or windshields.

And in the dog days of summer in Baltimore, it's more common to be around the mid-60s, where humidity starts to feel uncomfortable, or even above 70 degrees, when it feels oppressive.

Temperatures are forecast to be cool, at 5 or so degrees cooler than normal with highs hovering around 80 degrees.
