No major changes from the preliminary forecast, but there are a few minor adjustments to the timeline and snowfall amounts. Be safe out there!
Final Storm Timeline
- Light snow showers begin during the morning between 7am and 11am.
- Light snow becomes steadier and possibly moderate at times after 12pm.
- Snow continues at varying intensities (light to moderate) thru Saturday night
- Snow tapers off Sunday morning between 5am and 9am.
Final Storm Impacts
- Very light snow likely during AM and early afternoon, with minimal accumulation expected (a dusting).
- Accumulating snow likely begins during the early afternoon hours (after 12pm)
- Very cold temperatures in the low 20s Saturday afternoon, falling into the mid teens Saturday night.
- Very Cold air = Fluffy, high ratio snow
- (normally 10″ snow to 1″ liquid… this storm likely 20″ of snow to 1″ liquid).
- Very Windy Saturday Night (after 9pm) and Sunday:
- Winds out of the north / northeast increasing to 10 to 20mph, gusting over 40mph
- Blowing and drifting snow Saturday night into Sunday.
- Dangerous wind chills on Sunday afternoon -10° to -30°
- Cold temperatures = snow covered, icy and potentially treacherous roads.
- Potential for near blizzard conditions after midnight, due to falling snow and very strong winds, with reduced visibilities.
Final Snow Accumulation
- All 9 Zones : 3 to 6 inches… locally 8″+
We are closely monitoring a threat for higher snowfall amounts than what we are forecasting. As the storm intensifies off shore today, an inverted trough (frontal boundary) will extend well northwest from the system. This boundary between the cold air we already have in place, and the brutal polar air that is heading our way… will generate additional lift, and cause a band of enhanced snow to develop. Where this boundary sets up is vital to forecasting snowfall amounts, because areas under the trough (boundary) for an extended period of time (when factored in with the bitter cold air), could see snowfall totals exceed 8 inches of fluff. A lot of short range data is beginning to point to parts of the HV being under this boundary of enhanced snowfall. This is something to keep in the back of your mind, if we have to increase the snowfall forecast later today.
We will have additional commentary and storm updates shortly.
