Area Forecast Discussion...Update
National Weather Service Little Rock AR
630 AM CDT Mon Aug 14 2017

.AVIATION...

VFR and MVFR ceilings will mainly be seen to start the forecast,
with isolated IFR conditions possible with fog or heavy showers and
thunderstorms. Scattered showers and isolated thunderstorms will
continue to move across Arkansas today, as a weak frontal boundary
and upper system develop the convection. The highest rain coverage
will be over southern AR. The morning fog will gradually thin
through the morning. Winds will be light and variable to light east
to southeast this morning, then become east to south at 5 to 10 mph.

.Prev Discussion.../ Issued 331 AM CDT Mon Aug 14 2017/

Main concerns in this forecast cycle are first period fog, dense in
spots, potential. Then convection chances each day, with any severe
storm threat, and finally a temperature forecast through the week.

Currently seeing some patchy fog in many spots over AR, while a
few locals dense. Temperatures and dew points temperatures were in
the mid 60s to mid 70s. A weak frontal boundary was noted over
central AR, with a weak high pressure to the northeast of AR. A
bit warm and more moisture air was south of the boundary, while a
bit cooler to the north. Early morning convection was focused
over southern AR, associated with upper level shortwave energy,
while spotty convection over central and northern areas. A large
area of convection was over south- central OK to north TX, which
was slowly moving southeast. Cirrus blow- off clouds were
streaming into AR.

&&

.SHORT TERM...Today Through Tuesday Night

Forecast will start with the patchy fog, dense in spots especially
over northern AR, while the best chance of convection over the
southern. Likely POPs will be over southern AR, while chances the
rest of the state. Through today, models slowly lift the weak
frontal boundary more north, and with continued upper level short
wave energy moving through the upper west flow, a good to likely
POPs will be seen. Have adjusted to more of a shower event with
isolated thunderstorms per trends over the last few days. Tonight,
rain chances lower with a lowering of upper shortwave energy.
Areas of fog will again be seen. On Tuesday, much of the
convection should be in the morning as upper energy moves through
AR, while the afternoon POPs lower from west to east. Tuesday
night, rain chances lower as some upper level high pressure
ridging builds into AR, and an overall lower of any shortwave
energy in the mean flow. Patchy fog will again be seen.
Temperatures today will remain below normal and be from the upper
70s to mid and some upper 80s. A bit warmer Tuesday with highs in
the 80s to some around 90 degrees. Lows mostly in the 60s to
lower 70s.

&&

.LONG TERM...Wednesday Through Sunday

The gist of the long term forecast is this - slightly warmer, and
more humid like the last few days, with a chance of rain for much of
the forecast area essentially each day. For a little more detail,
continue reading below.

Upper ridging anchored over the southeast United States on
Wednesday, will subside somewhat as it gradually shifts west along
the Gulf coast through Friday thanks to yet another trough moving
through the upper midwest. Such a pattern will produce a persistent
return flow pattern at the surface with, generally speaking,
southerly winds across the state. However, with the ridge to the
south of Arkansas by Thursday morning, and the aforementioned trough
to our north, a frontal boundary will approach Arkansas from the
north. This will likely remain situated there until well into the
weekend. While the front isn't expected to move into the front, the
overall setup aloft and at the surface will allow for chances of
showers pretty much each day during the long term period. So despite
a slight warmup and return of humid conditions, temperatures won't
warm too much, only just getting back to seasonal norms, thanks to
the continued cloudy and rainy conditions.

This Hazardous Weather Outlook is for a Large Part of Arkansas.

.DAY ONE...Today and Tonight

Isolated to scattered showers and isolated thunderstorms will be
possible today, while a bit lower coverage tonight. Only an
isolated strong to severe storm will be possible, while the overall
threat will be low and isolated. Strong winds will be the primary
threat. Also, stronger storms will be capable of producing heavy
rainfall, which could led to localized flooding. Additional,
patchy fog will develop, dense in spots, and will be seen early
this morning and again late tonight, especially in those areas
that see rain.

.DAYS TWO THROUGH SEVEN...Tuesday Through Sunday

Showers and thunderstorms are expected to affect most of the state
again on Tuesday. The main threat with any convection will be the
possibility of heavy downpours and localized flash flooding,
especially in the Ouachitas.

Wednesday and through the end of the week to the weekend, isolated
to scattered, mainly afternoon and evening thunderstorms will be
a possible each day. Widespread severe storms are not expected,
but stronger storms could produce gusty winds and perhaps some
small hail.

.Spotter Information Statement...

Spotter activation is not anticipated today or tonight, but
reports of significant weather are requested.
