The National Weather Service in Albany, NY has issued a winter weather advisory for the Capital Region, Mohawk & Schoharie Valleys, and points south through 7AM EST Saturday morning. According to the official statement, maximum snowfall rates of anywhere from a half an inch to an inch per hour are possible later this evening through early Saturday morning creating hazardous travel conditions.
Low pressure, developing along a stalled out cold front over the mid Atlantic states, will move to the New England coast by Saturday morning and out to sea quickly by Saturday afternoon. A wintry mix of precipitation will slowly overspread the Capital Region and vicinity, from southwest to northeast, through the evening hours on Friday.
Initially, temperatures in most areas will be sufficiently above the freezing mark, allowing plain rain to fall. Higher elevations and sheltered valley locations may see more of wintry mix of sleet and freezing rain at the onset.
Colder air will be drawn into the entire region slowly during the evening hours, owing to two factors. Primarily, the passage of a cold front earlier today. Secondly, precipitation falling into relatively drier air in the low levels at the onset, causing temperatures to drop via the evaporative cooling process.
Any initial rainfall is expected to transition to a wintry mix of freezing rain, sleet, and snow during the evening hours. Snowfall is then expected to be the predominant precipitation type by midnight, as temperatures drop below the freezing mark. Snow may come down at a moderate to heavy clip for a time during the pre-dawn hours on Saturday, before precipitation tapers off by early Saturday morning.
Snowfall accumulations of 3 to 5 inches are forecast across the region by the time the event winds down during the early morning hours on Saturday. Portions of the Catskills may see higher snow accumulations. Any rain that had fallen across the region during Friday evening will freeze as temperatures fall below the freezing threshold, creating slick roadways and travel conditions.
Those with travel plans across the Capital Region and surrounding areas this evening and overnight should use extra caution. Untreated surfaces will become slick and hazardous during this period of time.
