An arctic front moved though Friday night and plunged our temperatures into the single digits across southern New England. Wind chills are between -10 and -25 degrees too.

This means more sleet contamination as warmer air nudges in aloft and an onshore ocean wind adds some warmth too. A coastal front sets up around Boston, southeastern Massachusetts and across Cape Cod.
