.Prev Discussion.../ Issued 254 PM CDT Sun Aug 20 2017/
.SHORT TERM...Today Through Tuesday

Another hot day across much of Arkansas today, with readings in the
90s across the entire state. The only exception to this would be a
few rain cooled sites across mainly northern and northeast Arkansas
where scattered thunderstorms have developed. These storms have
actually formed on a residual outflow boundary from a complex of
thunderstorms that moved out of northeast KS and northwest MO
overnight. Storms will persist mainly during the daylight hours,
with perhaps a few storms persisting into late evening.

Arkansas will remain on the western periphery of a mid level ridge
Monday into Tuesday, with surface ridging in place just to the
southeast of the state. During the day Tuesday, a surface front will
make its way toward Arkansas from the north and the mid/upper level
flow across the region begins to turn more northerly. Rain chances
will increase from north to south with this feature.

For the solar eclipse fans across our forecast area Monday, not much
change was made to the ongoing forecast. It will feel unpleasant
outside with temps mostly in the lower 90s and heat indices around
100 degrees. Looks like we will see partly to occasionally mostly
cloudy sky conditions for a good portion of the area. But,
similar to today, there should be plenty of breaks in the clouds
and even some places with few clouds especially during the
beginning of the eclipse, which should enhance viewing. Some
isolated to scattered showers and thunderstorms may be seen as
well.

.LONG TERM...Tuesday Night Through Friday

Scattered to numerous showers/storms will be ongoing acrs much of AR
on Wed, as the aforementioned CDFNT wl be working SWD thru the
state. Models are in good agreement with general timing of the fntl
bndry, pushing it well S of AR by Thu. Still cannot rule out a few
strong/severe storms with this system. Left some lingering rain
chances across SRN half of the FA Wed ngt.

Sfc high pressure will build into the region for the remainder of
the work week. The high center wl actually track acrs the Great
Lakes region and into the NERN states, with AR being on the S/SERN
periphery. This wl result in a return to below normal temps, with
highs mainly in the 80s, and lows in the upper 50s/upper 60s. Does
appear that the high`s influence wl weaken enough heading into next
weekend, to allow warmer and more humid air to begin returning to
the FA.
