Clear skies and relatively warm temperatures will greet commuters as they exit their offices and head out of Boston today.

Tracks for Massachusetts Bay Transportation Authority commuter rail riders and T riders were mostly clear as of 5 p.m., according to the MBTA's service alerts. The Red Line is delayed around Harvard Square due to signal problems.

Many MBTA bus routes are experiencing typical delays due to rush-hour traffic around the city.

Traffic is beginning to slow down right now in the Metro area, with a jam up slowing things down to under 30 miles per hour along the length of Route 93 south, according to real-time Massachusetts Department of Transportation traffic reports.

Jam ups expected along the Massachusetts Turnpike did not materialize Monday morning, despite predictions by MassDOT officials, WCVB reported. The morning commute was the first to feel the full impact of the state's switch to all-electronic tolling. Construction crews are working to demolish 26 toll plazas along the length of the highway, which is expected to cause some congestion.
