NATIONAL SUMMARY

The same storm that produced the deadly tornadoes in the middle of
the nation Saturday was affecting the mid-Atlantic region Monday as a
potent wind and rainstorm, similar to an early spring nor'easter. Up
to several inches of rain have fallen thus far from the storm over
parts of Maryland, Virginia and Delaware. Unseasonably chilly air
made for a raw day in parts of the Great Lakes and the Northeast on
Mother's Day. Just enough cold air fed into the back side of the
storm Monday morning to allow snow to fall on parts of western and
central Pennsylvania. Dry, stable air pushed into much of the
Southeast and the Mississippi Valley in the wake of the recent
damaging thunderstorms and tornadoes from the weekend. However, a new
storm was already dropping southward through the Rockies, bringing
snow to high elevations and rain showers to lower elevations. Over a
foot of snow is expected to fall on the higher elevations of Colorado
and southern Wyoming. The same storm may go on to spark another
severe weather and tornado outbreak over the southern Plains, Texas
and the lower Mississippi Valley in the coming few days. Gusty winds
on the back side of the new Rockies' storm has begun to deliver gusty
winds to portions of the Pacific coast and the mountains and passes
of California Monday.

SPECIAL WEATHER

Two Nor'easters in Four Days

The second potent rainstorm in four days hit the mid-Atlantic
region Sunday night into Monday. Parts of Maryland, Virginia and the
District of Columbia have received from 4 to 8 inches of rain from
the two storms. The heavy rain from the storms has led to flooding of
many secondary roads in multiple counties of the region. Sinkholes
have opened up as rain water seeped down into prior unexposed cracks
or gaps in the layers of limestone, underneath the topsoil. A new
sinkhole Monday morning forced the closure of a 4-lane highway in
Nokesville, Prince William County, Va.
