Conclusion Conts.
•Surface
wind ≤ 20 knots enhances moisture and increases parcel time over the warmer waters
•Surface wind > 20 knots increases crystal
fragmentation on the ground and causes higher snow density (less accumulation)
(Roebber and Schultz 2002)
•>80% RH values between 1000-700mb and in favorable
dendrite snow growth region with upward vertically velocities enhances
snowfall accumulation rates
•Surface dewpoints near 20F and PW around 0.30”
•Southwest low level flow is enhanced by upslope lift from
the Adirondacks and Western Slopes of The Green Mtns
•>8.0˚C/km
1000-700mb lapse rates and CAPE values between 200-400 J/kg create deep layer
instability for convective bands producing very heavy snowfall rates
•Sfc front combined with strong 5h PVA helped to enhance
lift and transfer significant snowfall 300 km downwind of Lake Ontario
