The tall ships moored around the Baltimore harbor for the Star-Spangled Sailabration will depart just ahead of a brief heat wave setting in Wednesday, meaning one last day of pleasant weather to watch the ships sail away on Tuesday.
The tall ships are scheduled to raise their sails and breeze southward in the "Parade of Sail" between 11 a.m. and 1 p.m. Tuesday. Navy warships will depart before that, from, 7 a.m. to 11 a.m.
Winds will be coming from the south-southeast, potentially hampering the tall ships from departing under sail. But winds are forecasted to be light, about 6 mph.
Temperatures will be in the upper 70s and low 80s for that period, with some humidity, according to the National Weather Service. Dew points are forecast around 65 degrees, uncomfortable for some people.
Wednesday and Thursday, the real heat should arrive. The weather service is forecasting highs of 95 and 99 degrees, respectively, with heat indexes approaching or surpassing 100 degrees.
High temperatures are forecast to return to the 80s on Saturday.
