Latest EPS/GEFS suggests a brief period of cool and drier
weather is likely Friday/Friday night associated with a surface
high passing north of PA. However, medium range guidance
indicates additional waves of low pressure riding along the
stalled front will result in a rainy weekend. Latest ensemble
mean qpf between Wed PM and Sun PM ranges from 1.5 to 2 inches
over much of Central PA, which would certainly be beneficial
given the recent dryness. This is especially true over the
southeastern part of central PA, which has been under moderate
to severe drought conditions for quite some time.
There is broad consensus among medium range guidance that upper
troughing builds over the region early next week, accompanied by
below normal temperatures and scattered rain/snow showers over
the Allegheny Plateau. Below average temps are favored for much
of next week, which could raise some frost/freeze concerns as
the spring growing season gets underway.
