The near-surface temperature was near or below freezing and decreasing because of diabatic cooling and cold advection over much of the northeast United States, ensuring that most precipitation would be frozen.
But while some backing with descent into the boundary layer can be expected, it is also shaped by the thermal wind relationships: if strong cold advection is in progress, the expected veering with height (backing as you descend) will be negated by backing with height.
The physicists also analysed the thermal structure of the lower atmosphere, and found "significant daytime cold advections (horizontal transportation of heat by an air current) in springtime, with temperature differences of 4.
