The models have trended warmer with the storm. Both the NAM and GFS now tilt the trough negative earlier, bringing low pressure further west. This will result in even more available water equivalent, however less time as snow. At this point, total this evening through Wednesday evening, we could see around 1.5" of water equivalent. Mainly snow through 2am, mixing with sleet and freezing rain thereafter. Still looks like a decent front end dump with snow rates around an inch per hour for at least 4 hours, so no changes to my snowfall forecast. In stead of going back to light snow on Wednesday, secondary low pressure now moving closer to the region will give us another thump of precipitation, but with warmer temperatures maintaining either freezing rain or plain rain through the evening before tapering off.
Snow accumulation forecast: 5" to 8"
Ice accretion forecast: .2" to .35"
