.DISCUSSION...
KEY MESSAGE 1...Freeze Warnings are in effect in the Appalachians,
Blue Ridge, and central Shenandoah Valley. Frost Advisories are
in effect from central Maryland into parts of central Virginia
tonight and early Sunday.

Temperatures will fall into the upper 20s to middle 30s
widespread tonight into early Sunday. Winds will lessen to light
to near calm in many areas. Freeze Warnings extend from western
Maryland, into parts of northeastern West Virginia, as well as
the central Shenandoah Valley from 2am tonight through 9am
Sunday. Also, lack of cloud cover and availability of light
winds to calm winds will allow for areas to widespread frost to
the east. Frost Advisories extend from central Maryland, the
eastern West Virginia Panhandle, and along the eastern slopes of
the Blue Ridge into the Virginia Piedmont.

KEY MESSAGE 2...Showers remain possible at times next week as
temperatures rise to near or above normal. Heavier showers and
thunderstorms are likely Wednesday and Thursday.

Temperatures will trend above normal during the first half of
the week. A strong frontal system will bring the likelihood of
showers and thunderstorms mid week.

Heights will rebound during the first half of the week leading to
warming trend. A few showers are possible Tue afternoon due to
shortwave energy passing by and weak instability.

An amplifying upper level trough over the Great Lks region into
the mid MS River Valley and Midwest will lead to the
development of a pair of surface lows which are expected to
track across the Mid- Atlantic region during the middle of next
week bringing widespread beneficial rainfall. There have been
large inconsistencies among model guidance with the second sfc
low with prior runs indicating low track across Pennsylvania and
putting local area in the warm sector with the risk of severe
wx with most recent runs indicating a track south of the area
keeping area in cool sector, minimizing severe risk and bringing
much needed beneficial rainfall.
