February’s which open warm have a knack for producing significant snows. Of ten such Februarys identified with mild temps at the start, six of them (60%) produced one or more 3”+ snows in the weeks which followed.
The system, predicted to begin producing snow here Tuesday night lasting through Wednesday morning’s rush hour, has been tracked for more than a week. Unusual only because it lacks a well defined ground-level low pressure (an “L” on the weather maps), the system possesses a more than an adequate supply of moisture. The moist air is likely to be hoisted aloft and converted into clouds and snow through the action of powerful jet stream winds due to arrive late Tuesday night. While unlikely to produce major (6”+) accumulations, the disturbance appears more than capable of producing 1-3” totals. But, the eruption of any convective snowfall (bursts of heavier snow from taller clouds embedded within a large snow area) could produce higher totals.
