Boston Weather: 49.0°F | Partly Cloudy

Weather: Cap, Gown, and Umbrella

By Bill Ramstrom
STAFF METEOROLOGIST -- While New England has been experiencing drought conditions this winter and spring, unfortunately the replenishing rains will be falling on graduation day. Rain or showers are likely through the morning, gradually tapering off in the afternoon.

A front over the eastern US has been moving slowly southeastward over the last several days. Behind it is a much cooler and drier air mass.

But warm, humid air is being forced up over the leading edge of the cooler air mass, leading to the widespread rains we have experienced since yesterday. In addition, a wave on this front is helping to slow its eastward progress, while at the same time enhancing the precipitation.
