Good afternoon everyone, While we work on our updated winter storm graphics, we wanted to communicate with you our* key messages* - 1) snow begins after midnight regionwide 2) heaviest snow falls from about 4 AM to 8 AM in CT, RI and southeast MA, then snow changes to sleet and freezing rain, finally over to all rain by noon. For northern MA, heaviest snow persists until late morning before tapering off to light snow in the afternoon. This includes the Greater Boston area. 3) some improvement for the afternoon across eastern CT-RI and eastern MA, including the Greater Boston area, as temperatures rise above freezing 4) colder air surges back into RI and eastern MA between 4 pm and 7 pm, with temperatures falling below freezing. Thus, any remaining slush or residual road moisture will freeze, hence flash freeze possible late afternoon into the evening. We will send an updated briefing package with graphics between 3 pm and 4 pm.
