A strong cold front swept across the region during the evening hours of Christmas Eve. Along and in advance of this cold front, very gusty winds occurred. Some were strong enough to down trees and limbs in parts of Roanoke and Smyth Counties. While rain preceded the cold front, sub-freezing air rapidly entered the area after the passage of the cold front, dropping the temperatures some five to eight degrees per hour. This quickly turned the rain to snow, and resulted in flash freeze of surface moisture to slippery ice. The snow quickly accumulated during the night, with parts of southwest Virginia receiving four to six inches of snow. Key impacts: slippery roads and sidewalks, falling trees.

A shortwave trough ejected east out of the base of a longwave western US trough, lifting across the southern plains and into Iowa. Strong frontogenesis led to a band of heavy snow on the leading edge of the system on the morning of the 29th. A secondary surge of moisture lifted into the area later in the day thanks to a strong 70 knot low level jet. Precipitation began initially as sleet and freezing rain across southern Iowa with a deep warm inversion above the surface, but by midday precipitation transitioned over to all snow. Snow rates exceeded 1+ inches per hour at times through the afternoon and early evening before tapering off later that night.

A strong warm front moving northeast across southern New England and an approaching short wave trough combined to produce a weak tornado in western Massachusetts during the early evening hours.

Tornado in HAMPDEN, MASSACHUSETTS
From 02-AUG-20 17:59:00 to 02-AUG-20 18:20:00 (EST-5)
Location: TOLLAND
Tornado F-scale: EF0
Property damage: 45.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

A National Weather Service survey team concluded that a weak, narrow, but relatively long tornado occurred during the evening on Sunday, August 2 in western Massachusetts. It began in the southeast part of Sandisfield (Berkshire County), moved northeast across northwest Tolland (Hampden County), and lifted in the southern portion of Blandford (Hampden County). Damage was mainly to trees but some minor home damage occurred in Sandisfield. The EF-Scale rating was EF-0, with estimated maximum wind speeds of 80 mph. The tornado was on the ground in a mainly continuous path for a little more than 8 miles, with a maximum width of approximately 100 yards.
The tornado began in Sandisfield, just west of South Main Street.  Some tree damage was observed on Carpenter Lane and on South Main Street at and just north of the Mile 4 marker.  A home there had its upper window blown in, shingles ripped off, and the portico was lifted upward, enabling the supporting post to be shifted outward.  Some corn stalks were flattened and a neighbor's fence was blown down.
In Tolland, trees were observed to be blown down in various directions from East Otis Road to the west shore of Twining Pond, where drone footage provided by an amateur radio operator showed a couple of dozen trees blown down in a narrow swath.  Continuing to the northeast, many trees were downed on Belden Road and on a narrow portion of Schoolhouse Road just north of Belden Road.  The damage became sporadic as it ended with some wires downed in Blandford, just west of the north end of the Cobble Mountain Reservoir.
