Special Weather Statement issued October 31 at 4:35AM EDT by NWS Boston/Norton MA

Patchy black ice is likely early this morning as temperatures in the 20s results in moisture freezing on untreated roads. This is especially true on bridges and overpasses. Motorists should exercise caution if traveling early this morning. Any pavement that looks damp may be icy. Temperatures will rise above freezing around mid to late morning which will alleviate any problems.
