.PREV DISCUSSION...(ISSUED 400 AM CDT Sat Jul 20 2019)
SHORT TERM...Today Through Sunday Night

Warm and humid conds once again noted acrs the FA early this mrng.
High pressure aloft wl rmn in control over the region today. Stuck
with persistence regarding high temps today, ranging fm the upper
80s to the mid 90s. Aftn heat index values wl reach the critical 105
degree threshold this aftn, mainly ovr a small part of central and
northeast sections of the FA. Went ahead and issued a Heat Advy for
those areas. Cannot rule out a stray shower or storm over far SE AR
this aftn, but once again expect a dry day.

Heading into Sun/Sun night, the advertised upper flow pattern change
wl commence. High pres aloft wl start to bld acrs the Rockies, with
the steering flow over the Mid-South eventually becoming NWLY
thereafter. This wl allow a new CDFNT to eventually apch the FA fm
the NW, primarily beyond this fcst PD. SCTD convection wl mainly
affect the NW part of the area later Sun night.

LONG TERM...Monday Through Friday

A large area of high pressure aloft will be over the Rockies to
begin the long term period. This will provide northwest flow to
Arkansas. With the ridge remaining over the West, the northwest flow
will continue over the mid south through the period.

A cold front will move through Arkansas Monday and early Tuesday
with showers and thunderstorms. Surface high pressure then moves in
behind the front. The front will bring cooler temperatures, which
will be well below normal. Highs in the 80s and lows in the 60s will
be common.
