Inside of 36 hours from the event, here is our preliminary storm forecast. This forecast is subject to minor adjustments over the next 24 hours…
Preliminary Storm Timeline
- Light snow showers begin during the morning between 7am and 11am.
- Light snow becomes steadier during the afternoon, possibly moderate at times by late in the day.
- Snow continues at varying intensities (light to moderate) thru Saturday night
- Snow tapers off Sunday morning between 5am and 9am.
Preliminary Storm Impacts
- Very light snow likely during AM and early afternoon, with minimal accumulation expected (a dusting).
- Accumulating snow likely begins during the mid afternoon hours
- Very cold temperatures in the low to mid 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 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 due to falling snow and very strong winds, with reduced visibilities.
Preliminary Snow Accumulation
- Zones 1 & 2 : 3 to 8 inches of snow
- Zones 3 thru 9 (remainder of HV) : 2 to 6 inches of snow
A close call for the Hudson Valley, but it appears that the deep intensification of this storm, will occur about 6 to 12 hours too late for the Hudson Valley. The worst impacts of this storm (heavy snows and blizzard conditions), will be confined to New England, and possibly Boston yet again.
With that said… the Hudson Valley will not escape unscathed.
Light snow will break out into the HV during the early part of the day… but likely not accumulate until the afternoon. We’ll track the progression of the situation as it unfolds.
Steady, accumulating snow develops during the afternoon and continues into the night on Saturday. We are watching a potential wildcard situation, with an inverted trough extending NW from the storm. Along this boundary, there could be an enhanced area of snow. Some of the data has this inverted trough setting up over the HV, and if it does… we could see a few locations exceed 6″. But for now… we’re remaining conservative with the 3 to 6 inches in general.
You can see… we don’t miss out by much on this system. It’s another close call for the Hudson Valley… but it looks like we’ll miss the worst of this one.
