An upper ridge will remain over the mid-south through the middle
of next week. By Wednesday, the ridge will begin to move east as
an upper trof moves eastward out of the Central Plains.
Through Tuesday, expect only diurnal chances for showers and
thunderstorms. Today, best chances for showers and thunderstorms
will occur across west Tennessee near the Tennessee River and
northeast Mississippi. Highs will range from the upper 80s to
lower 90s through the period. Although, humidity levels may
decrease over the weekend into early next week as surface winds
turn out of the east ushering in drier air.
A cold front will approach eastern Arkansas on Wednesday. Showers
and thunderstorms will develop along and ahead of the front,
possibly impacting eastern Arkansas by the afternoon hours.
VFR conditions to prevail over the next 24 hours. South winds
generally 5 knots or less at all sites through the period.
Scattered showers possible during the day, but coverage too low
to mention in the taf at this time.
