Good afternoon everyone Attached is our briefing package on the upcoming wet snow event overnight into Saturday. We have also included our snowfall forecast for the Sunday evening into mid morning Monday storm in second graphic. Lastly, please stay tuned for additional emails and another possible conference call sometime on Saturday. *Overnight Into Saturday:* What: - Wet Snow with accumulations of 2 to 6 inches across most of the region with 4 to 8 inches across Southeast MA. Lower amounts forecast on Cape Cod where some rain and sleet may be mixed in at times. Where: - All of southern New England with the heaviest snow expected across southeast MA into Rhode Island. When: - Snow develops from south to north after midnight. Heaviest snow expected from 4 am Saturday through noon with 1 inch per hour snowfall rates across RI and SE MA. Lighter snowfall continues Saturday afternoon. *Potential Impacts/Uncertainty: * *- *High confidence in a plowable snowfall for much of the region. - Main uncertainty is if higher snowfall amounts are realized, increasing the risk for isolated to scattered power outages. Greatest risk for this is across southeast MA and RI. - Lower confidence in snowfall amounts across the Cape and Islands with snow potentially mixing with rain and sleet. *Sunday Evening Into Mid Morning Monday:* *What:* - Significant snow accumulation possible. - Impacts to the Monday morning commute especially across the interior. - Risk for isolated to scattered power outages from northern CT into northwest RI and northeast MA if higher snow amounts are realized. *Where:* - Greatest risk for significant snow will be northwest of the Boston to Providence corridor, but significant snow is still possible in the Boston to Providence corridor depending on the exact track. *When:* - Snow develop between 4 and 8 pm Sunday evening and will be heavy at times during the overnight hours. - Snow may change to rain across portions of eastern MA and RI depending on the exact track. - Precipitation tapers off by mid morning Monday *Uncertainty:* - There is still considerable uncertainty with the storm track which will determine where rain-snow line sets up and where axis of heaviest snow occurs - It is still too early to give specific snowfall amounts - We will know more each day but probably will not have higher confidence in snowfall amounts until Saturday Please let us know if you have any questions or concerns. We have briefing package update by 6 am Saturday Morning.
