A weak area of low pressure was centered over southeastern Ontario province in Canada Friday morning. This area of low pressure was slowly decaying, however, this disturbance was generating some light snow across the immediate Capital Region, and will continue to do so through the day today.
Friday afternoon, a secondary area of surface low pressure is forecast to redevelop near New York City and track east to be east of Cape Cod early Saturday morning. A trough of low pressure is forecast to develop and persist between the decaying, and developing, systems and oscillate north/south across the Capital Region through Saturday. This will produce periods of light to moderate intensity snowfall through this period. There may be some bursts of heavier snowfall as well. As the entire system lifts northward into the Canadian Maritime provinces later Saturday and into Sunday, snowfall should abate. There may be some residual lake effect snow and snow shower activity from time to time, especially in areas north and west of the region. Winds should also increase on Sunday, as low pressure strengthens rapidly over the Maritimes and creates quite the pressure differential between itself and high pressure forecast to be over the Tennessee Valley.
The new work week looks to start out relatively quiet, under high pressure’s subtle control. With near to slightly below normal temperatures and dry conditions expected.
Below is the forecast for the Albany, Schenectady, Troy area and vicinity…
