05 Feb '19

Good afternoon, 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. *A **Winter** Weather Advisory has been issued for all of Massachusetts and Rhode Island, expect for the immediate south coasts of both states, as well as for northern Connecticut.* *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.

[2019.02.04 PM Update] Icing Potential Wednesday Night Into Thursday Morning
by BOX Operations - NOAA Service Account 04 Feb '19

04 Feb '19

Good afternoon, everyone: We continue to monitor the potential for freezing rain and sleet late Wednesday into Thursday morning. The main area at risk for icing will be mainly away from the immediate coastline, although there will be some risk for icing near the coast, too. We will include a brief outline of expectations and also attach an image showing potential ice accretion amounts. *WHAT: * - Freezing rain. possibly mixed with sleet. *WHERE: * - Mainly northwest of the Boston to Providence corridor, and especially across the interior high terrain of Massachusetts. *WHEN: * - The threat for icing will be mainly Wednesday night into Thursday morning. While exact timing remains uncertain, it appears that the icing potential will occur after the Wednesday evening commute but may impact the Thursday morning rush hour. *IMPACTS:* - The main concern remains the potential for icy roads Wednesday night into Thursday morning, especially across the higher terrain of Massachusetts. *UNCERTAINTY: * - High confidence that a period of icing impacts the higher terrain of Massachusetts. - Greater uncertainty exists on whether a period of icing impacts the lower elevations near the Boston to Providence to Hartford corridor. - Ice accretion amounts are uncertain, but odds of exceeding one quarter of an inch anywhere in southern New England are low at this time. Therefore, the threat for tree damage and scattered power outages is also rather low. Please let us know if you have any questions or concerns.

Good morning everyone. Despite the unseasonably mild weather today into Tuesday afternoon, colder weather along with the threat for a period of icing exists Wednesday night into Thursday morning mainly northwest of the Boston to Providence corridor. We will include a brief outline of expectations and also attach an image showing potential ice accretion amounts. *WHAT: * - Freezing rain possibly mixed with sleet. *WHERE: * - Mainly northwest of the Boston to Providence corridor and especially across the interior high terrain of Massachusetts. *WHEN: * - The threat for icing will be mainly Wednesday night into Thursday morning.

Therefore, the threat for tree damage and scattered power outages is also rather low. Please let us know if you have any questions or concerns.
