Forecast Discussion

A boundary of arctic air will arrive in Maryland Saturday afternoon and evening causing temperatures to fall into the middle and upper 20s Saturday night with dew point values (the measure of moisture in the atmosphere) between the lower teens and 20s. Dew points will be critical to prescription. The lower the dew point the colder the atmosphere will become once the prescription arrives. It's a phenomena called evaporative cooling.
