Boston Weather: 63.0°F | Partly Cloudy and Breezy

Wear Sunscreen

STAFF METEOROLOGIST -- Skies will be mostly sunny for today’s commencement exercises in Killian Court, as several disturbances pass offshore a few hundred miles to our south. A steady west-to-east flow at upper levels of the atmosphere is keeping a large area of cloudiness and rain over the Southeast from advancing further northward.

Earlier in the week, models suggested that this weather would dampen the festivities today, but more recent runs confine all of the rain to the south of the Mason-Dixon line. The largest area of rain is associated with the remnants of Tropical Storm Allison, which is slowly dissipating over eastern Texas.

The fair weather will continue through the weekend, thanks to a large high pressure system that is building eastward from the Midwest. The days will be more and more sunny, so that by Sunday there should be clear skies. High temperatures will be in the upper 70s each day, with overnight lows in the mid to upper 50s.

Today: Partly cloudy and pleasant. High 76°F (24°C).

Tonight: Clear and mild. Low 57°F (14°C).
