.PREV DISCUSSION... /issued 338 AM CDT Tue Oct 17 2017/

DISCUSSION...Surface analysis early this morning places a 1028 mb
ridge of high pressure centered over the Ohio Valley and Lower
Mississippi Valley. This is resulting in clear skies and light
winds across the region. As of 3 AM CDT, temperatures across the
Mid-South range from the upper 30s to lower 40s across portions of
West Tennessee, and 40s across the remainder of the forecast
area.

Surface and upper level ridging will remain in place across the
Lower Mississippi Valley through Friday night. This will result in
a continuation of rain free weather across the Mid-South each day.
Highs will be in the 70s with lows mainly in the 40s gradually
warming into the 50s by Friday night.

Latest long term models indicate rain chances will increase across
the Lower Mississippi Valley for late Saturday night into next
Monday as a positively tilted upper level trough and associated
cold front move through the region. Long term models have come
into better agreement than previous runs and adjusted rain chances
accordingly. Temperatures will average slightly above normal this
weekend with a potential for slightly below normal temperatures
towards the end of the period.
