Area Forecast Discussion
National Weather Service Little Rock AR
242 PM CDT SAT AUG 13 2016

.SHORT TERM...Tonight Through Sunday Night
Recent radar data indicate an increase in coverage and and
intenstity of convection across west central through northeast
sections of the forecast area. This activity appears to be aided
by an upper level deformation area...which is forecast to remain
in this region through early evening...before moving north.

Abnormally high moisture values...acted on by efficient warm cloud
processes...ill continue to promote a flash flood threat across
north central sections through this period...and beyond.

&&

.LONG TERM...Monday Through Saturday
The fcst wl cont to rmn unsettled acrs the FA as the upper flow
pattern stays rather stagnant. The remnants of the sfc bndry...along
with an upr lvl shear axis ovr the region...wl result in several
rounds of SHRA/TSRA for much of the FA. Heavy rain potential wl cont
to be the highlight for the new work week.

As is the case with this type of scenario...the exact location of
the fntl bndry wl determine the favored areas for heavy rainfall. As
it stands now...the models indc a round of rainfall affecting the
WRN half of the FA on Mon. The next round is fcst to arrive later
Mon Ngt/Tue as another piece of upr energy lifts acrs the FA.
Abnormally high PW values wl cont to result in heavy rainfall/
flooding potential. A FF Watch rmns in effect for Mon for NRN AR.
The watch wl likely be extended if current fcst trends cont.

High pres aloft ovr the SERN U.S. is expected to weaken later this
week...which would allow for some movement in the upr lvl flow
pattern. Thus...the persistent upr trof axis would tend to sloly
shift to the SE. With several additional upr lvl impulses expected
to affect the FA...the axis of heavier rainfall would shift more
toward SERN AR. Have indcd this trend with POPS for the latter half
of the fcst pd.
