DISCUSSION...

Rain continues to fall across much of the Mid-South this morning
as the area is sandwiched between a stationary front to the south
and an approaching cold front to the north. The cold front will
push through the CWA today. As it does, the rain will shift south
and cooler temperatures will filter into the region.

High pressure will begin to build into the area tonight. Although,
winds may be gusty initially this evening, expect them to
diminish quickly during the overnight hours. The combination of
light winds and clear skies will allow for low temperatures to
drop into the mid 30s across Northwest Tennessee, the Missouri
Bootheel, and portions of Northeast Arkansas. As a result, frost
will develop before sunrise. Will issue a Frost Advisory for these
locations.

The SFC high will remain over the Mid-South through Sunday Night.
Sunday will be chilly across the area despite plenty of sunshine.
Cold air advection will keep highs in the 50s. Sunday Night could
be another night for frost development. Although, not as
confident as the SFC high will begin shifting east and cirrus
clouds may begin moving into the west.

Next week looks like a quiet weather week as only a couple of
upper level disturbances may bring small chances for showers but
for the most part most locations will stay dry. Temperatures will
remain below normal with highs in the 60s.
