Good morning everyone, We continue to monitor a low pressure system which will bring a period of snow, changing to rain for most, then back to snow late Tuesday into Wednesday. Due to uncertainty in how far inland the change to rain will penetrate, it is still difficult to determine snowfall amounts. See the included graphic for a rough estimate of areas where mainly snow, a mix, and mainly rain are expected. *What:* - A storm system, moving along the northeast coast. - Potential for a period of snow, with a risk for total snowfall reaching Winter Storm criteria for some especially across the western higher terrain. - Low risk for a period of ice and gusty winds. *Where:* - The highest risk for significant snowfall will be across northern and western portions of Massachusetts and Connecticut, with lower amounts toward the southeast coast. - Risk for icing and strongest winds highest across Rhode Island and Southeastern MA. *When:* - Beginning as mainly snow late Tuesday - Potential for a change to ice (with some snow continuing) early Wednesday morning. - Rain may change back to snow with additional accumulations possible Wednesday morning - Mostly done by Wednesday afternoon - Low risk for impact to Tuesday evening commute, higher risk for Wednesday morning commute. *When we will know more:* - We will begin to highlight details over the next 36 hours.
