.DISCUSSION...
A dry airmass will engulf the region today. Northwest winds will
generally be around 10-15 mph this afternoon. Although these winds
are not all that strong, surface dew points are anticipated to mix
down into the low to mid 20s. This will result in Min RH values in
the 20-25% range across E PA and NJ and 25-30% range across E MD and
DE. We will be in contact with our partners this morning to
determine if a SPS is needed.
