Area Forecast Discussion
National Weather Service Little Rock AR
555 PM CDT FRI SEP 16 2016

.AVIATION...
Scattered showers/storms will be possible over the northern sites
this evening, as a surface boundary moves across the region. Over
the central portions, precip should be more scattered. Thunder
chances will diminish after sunset. However, showers will remain
possible through the night, but should largely diminish after 06z
as any remaining convection shifts eastward.

Mvfr ceilings and visbys will become possible by morning,
especially in areas that have seen any rain. While conditions will
improve after sunrise, area should still see broken stratocu
through the day. Winds will largely be light and variable, except
gusty with any storms.

Tafs out shortly.

.PREV DISCUSSION...(ISSUED 300 PM CDT FRI SEP 16 2016)

SHORT TERM...Tonight Through Sunday

Wdly sctd convection noted acrs the FA this aftn...driven by aftn
heating and a MCV lifting acrs NE OK. Mid aftn temps ranged fm the
mid 80s to the mid 90s. Rapid update model data cont to suggest that
convection wl expand in areal coverage SWD acrs NRN and CNTRL AR
this evening. Have based POP trends on this scenario...with likely
rain chcs mentioned ovr N AR and lesser chcs to the S.

Still looking at unsettled conds persisting acrs the FA thru much of
the weekend...although not a total washout. A CDFNT wl cont to sloly
apch fm the Plains States...eventually entering NW AR later Sat and
Sat Ngt. The fnt is fcst to meander ovr the FA thru Sun. Looking for
sctd convection to rmn in the fcst...mainly diurnally driven as we
progress over the weekend. High temps wl hover close to or a bit abv
normal...with overnight lows in the 60s and lower 70s.

Long Term...Sunday Night through Friday

An upper trough and associated cold front should be south of the
forecast area by Sunday evening. Behind the Sunday upper trough,
high pressure will build into the central United States. However,
would not expect a cool down behind the front though as upper high
pressure will build into the central United States, keeping the
region dry and holding temperatures well above seasonal values. That
being said, would not be surprised to see some isolated showers or
thunderstorms especially on Tuesday afternoon near the Missouri
border where another weak front will be approaching from the north.
