Good morning, A wintry mix of freezing rain and/or sleet is likely Wednesday evening into Thursday. Please see the attached image with respect to forecast ice accretion amounts. *Our greatest concern is the potential for icing during the Thursday AM commute, especially across interior areas of Southern New England away from the immediate coast*. With any icing, untreated roadways will become slick resulting in hazardous travel conditions. In addition, there's a low risk of downed limbs due to the weight of ice with the potential for isolated power outages. *What / Where / When ...* - Initially sleet mixing with and changing over to freezing rain - Across the interior away from the immediate Southern New England shoreline, the largest ice accretion amounts are forecast for the Berkshires and Worcester Hills. - Developing Wednesday evening and continuing into Thursday, through the Thursday AM commute. - With any freezing rain, untreated surfaces will become icy resulting in hazardous travel conditions. *Uncertainty ...* - Challenges in forecasting the exact timing of precipitation-types makes it difficult to be certain to a high degree of sleet accumulation and ice accretion amounts, as well as if and when the transition to rain will occur. - While there is high confidence concerning wintry precipitation for Wednesday evening into Thursday, confidence is lower with respect to exact outcomes and subsequent impacts. - Expect future refinements to the forecast.
