Title: Snowstorm


1
Snowstorm
All snowstorms are associated with an area of low
pressure. Snow usually falls to the north and/or
west of a low pressure. Snowstorms can be small
storms (less than 6 inches) or big storms
(greater than 6 inches). They usually occur
between December and March, although we have had
rare snowstorms in November and April.
Snowstorms that impact the Philadelphia region
can be the result of a weak low, moderate low, or
strong low. Usually it is the dynamic
interaction between a low pressure to our south
and a high pressure to our north and/or west that
produces our most significant snowstorms.
