850 mb temps of -1C to -3C are advecting into the region with

otherwise things are on track.

PREV DISCUSSION... /issued 221 AM CDT Thu Apr 19 2018/

A cold front has pushed through the Mid-South which is allowing
temperatures to drop dramatically this morning. Expect a chilly
day across the area as cold air advection will occur with gusty
northerly winds, in addition to strato-cu development. Highs will
generally be in the 50s.

Skies will clear this evening as winds become light. This will
allow temperatures to plummet into the mid to upper 30s for much
of the CWA. Will issue a Frost Advisory for the Missouri Bootheel,
much of West Tennessee, and portions of Northeast Mississippi.

Temperatures will moderate on Friday, but will still be below
normal for this time of year. Expect highs in the mid to upper
60s.

Clouds will begin to increase on Saturday ahead of an upper level
low pressure system. Best rain chances should hold off until late
Saturday Night. Models are now in pretty good agreement with the
track and progression of the system. Sunday will be a wet and
dreary day across the Mid-South as the upper low moves into the
region. Some embedded thunderstorms could occur as well. Highs
will be in the lower to mid 60s.

Models indicate the upper low will slow in its progression
eastward thus rain chances will continue into Monday and Tuesday
especially over areas of West Tennessee near the Tennessee River
and Northeast Mississippi as the low stalls over Middle TN/
Northern AL. Temperatures will remain below normal.

The area won`t get a chance to dry out or warm up as another cold
front will sink into the region on Wednesday continuing rain
chances.
