It doesn’t feel much like June in Baltimore, but it’s not so much because of the (lack of) heat. It’s the humidity.
Temperatures dropped to 58 degrees early Friday morning at Baltimore-Washington International Thurgood Marshall Airport, and are expected to peak in the mid-70s Friday afternoon. That is about 5-10 degrees cooler than normal for this time of year.
What’s more remarkable is the lack of humidity at a time of year Baltimore typically feels downright swampy.
Dew points were in the mid-40s overnight and around 50 degrees by late Friday morning.
The dew point is the temperature at which air would need to cool for the moisture it contains to condense into liquid form. The higher the dew point, the more water vapor the air holds.
More typical for summer in Baltimore are dew points in the 60s, if not approaching 70 degrees sometimes.
