Area Forecast Discussion
National Weather Service Little Rock AR
1238 PM CDT Fri Jun 22 2018

.AVIATION...

Showers and a few thunderstorms are continuing to impact southern
Arkansas and will keep spotty showers and thunderstorms in the
forecast at KADF and KLLQ through the afternoon. Currently storms
are weakening but models do hint at redevelopment later this
afternoon. Tonight a storm system will move into the state from
the west. Models are continuing to struggle with this system and
latest trends have the system pushing a bit further south and
weakening as it enters the state. Due to uncertainty with this
system have continued the Prob 30 group for this system as
confidence remains low.

&&

.PREV DISCUSSION...(ISSUED 640 AM CDT Fri Jun 22 2018)
AVIATION...

Overall VFR flight conditions will be seen over the next 24 hours.
Early Friday morning, very spotty MVFR and IFR clouds may develop
over parts of southern AR, especially near KLLQ. Also, a cold front
will continue to slowly sag southeast through AR, with mainly a wind
shift and much drier air behind this front. Isolated to scattered
showers and thunderstorms will be seen also over southern AR near
the front. Winds behind the front will be west to northwest at less
than 10 mph, while ahead of the front southwest to west at less than
10 mph. (59)

Prev Discussion.../ Issued 347 AM CDT Fri Jun 22 2018?
DISCUSSION...

Main concerns in this forecast cycle are chances of convection
each day, and any threat of strong to severe storms, as well as
localized flash flooding due to very moist atmosphere.
Temperatures will start around normal values, then as rain chances
lower next week, temperatures again will be above normal values.

Early Friday morning, a cold front was sagging southeast over AR,
and generally from near DEQ to just south of LIT and to the
northeast to the MS river in TN. A drier airmass was behind the
front with a west to northwest wind. Temperatures were in the
upper 60s to lower 70s, while dew points in the lower 60s to mid
50s. South of the front, temperatures were in the mid and upper
70s, dew points in the lower 70s and winds light from the south.
An area of convection had formed at 315 AM CDT over southwest AR,
and with movement to the southeast. Aloft, the upper low pressure
system was over eastern MO to IL, and rotating some lift and very
light rain over northeast AR. Mostly mid and high clouds were
seen, with only patchy lower stratus clouds and fog in spots.

SHORT TERM...Today Through Saturday Night

All forecast models, especially the HRRR, has developed the
scattered convection just south of the weak cold front as it sags
southeast. Some lift is seen in guidance as it rotates around the
upper low pressure system. NAM and HRRR have a good forecast trend
of the convection as it develops over southwest AR, moving ESE and
becoming more widespread south of the boundary. The rest of AR
this morning will see a low chance of any rain. The drier airmass
will slowly filter into the state, while the energy rotating
around the upper low pressure system gradually moves east. Most of
today's convection will be confined to southern AR. Enough of
instability will be seen and an isolated strong to severe storm
may develop. Wind and hail are the primary threats. Friday night
to Saturday, models are consistent in stalling the frontal
boundary over or near central AR, and along with the upper zonal
to west flow, show a significant short wave and developing MCS, to
move across AR late Friday night to Saturday morning. The exact
location of the highest convection will be determined by where the
front will set up over AR. Chance to likely POPs are in the
forecast. Also some of the storms may reach severe levels with
winds and hail, with heavy rain, the main threats. Later Saturday
evening to Saturday night, forecast models lift the boundary north
as a warm front, and as additional short wave energy moves into
the region, additional convection may be seen over AR. Otherwise,
temperatures will be around to a bit below normal values.

LONG TERM...Sunday Through Thursday

Sunday...Precipitation chances will be dependent upon a number of
factors, most of which are mesoscale in nature and therefore
difficult to resolve 48 hours out. As discussed above, a mesoscale
convective system (MCS) is expected to move southeast along a
northward moving frontal boundary Saturday morning. This MCS will
likely produce a strong enough cold pool to reinforce the frontal
boundary making it quasi-stationary by Saturday night. The final
position of this front Saturday night into Sunday morning will
represent the best chances for showers and thunderstorms Sunday
morning.

Right now the consensus of model guidance is that this front/strong
remnant outflow boundary will be in place over northern Arkansas
Sunday morning. As a result, have the highest POPs at 30 to 40
percent across the northern part of the state. The coverage of
storms along this boundary will likely play a role in rain shower
and thunderstorm chances Sunday afternoon as well. The higher the
coverage Sunday morning...the more likely cool air will reinforce
the front leading to higher rain chances Sunday afternoon. The
problem for those wanting more rain is that the synoptic scale flow
supports frontolysis, so in the absence of mesoscale to storm scale
reinforcement, the front will likely weaken or dissipate Sunday
afternoon resulting in dry conditions. By Sunday night the model
consensus is for shortwave ridging aloft...so any lingering showers
or thunderstorms are expected to dissipate quickly after the peak
heating hours on Sunday.

Monday and Tuesday...The consensus of model guidance is that a
strong northerly shortwave trough will move east over the northern
plains Monday night and Tuesday. To the south...upper level ridging
will remain in control of the weather pattern for the region and
large scale forcing for subsidence should keep us dry to start out
the week. Subsidence during the time of year when heating/days are
the longest means that we will heat up quickly to start off the work
week. Highs are likely to climb into the mid to upper 90s by Tuesday
afternoon.

Wednesday through Friday...While model consensus is good through
Tuesday...the GFS and ECMWF diverge on the large scale pattern from
Wednesday through the end of the week. The GFS brings Tuesday's
northern stream trough far enough south to break down the upper
level ridge slightly and even breaks off a small piece of
energy/cooler air aloft and allows this to meander over Arkansas and
the nearby region through the end of the week. In this solution we
will still be seasonably warm...but each afternoon will feature
diurnally driven isolated to scattered showers and thunderstorms.
Wind shear is incredibly weak...so no organized convection is
expected if the GFS solution pans out.

The ECMWF solution keeps the northern stream shortwave trough a bit
farther north on Tuesday. This doesn't make much of a difference in
the short term...but from Wednesday through Friday the consequence
of this is that upper level ridging builds over the region and is
only reinforced by heating each day. By next Friday the ECMWF
advertises a 594 dm high over Arkansas while the GFS keeps
geopotential heights at 588 dm. These higher geopotential heights at
the 500 mb level a representative of the build up of heat in the
troposphere and would likely result in high temperatures climbing
into the upper 90s each day and may open the door for our first 100
degree day of the summer. Rain chances would be less likely, but
still not zero as the hotter temperatures would still allow for
airmass thunderstorms during the peak heating hours of the day, the
subsidence would simply limit the coverage to isolated as opposed
to scattered.

At this time went ahead and favored the GFS solution for the latter
half of next week. Kept high temperatures in the mid 90s each day
and limited POPs to 20 percent to account for the ECMWFs influence
of stronger ridging. If the ECMWF verifies will likely have to raise
temperatures in later forecasts and perhaps remove rain chances from
the forecast if subsidence is strong enough to overcome the low
level heat and humidity build up.

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

.DAY ONE...Today and Tonight

Isolated to scattered thunderstorms will be possible today,
especially over southern Arkansas. An isolated strong to severe
storm will be possible, with damaging winds and large hail the
primary threats. Tonight, another risk of an isolated strong to
severe storm will be possible, moving into Arkansas from the west
and moving southeast across the state. Damaging winds and large
hail will again be the primary threats. Also, potential heavy
rain may lead to localized flooding.

.DAYS TWO THROUGH SEVEN...Saturday Through Thursday

Isolated to scattered showers and thunderstorms are forecast across
northern Arkansas on Sunday, however the chances of severe
weather appears to be low at this time and cloud to ground
lightning and gusty winds are the primary threats.

Isolated thunderstorms are possible during the peak heating hours of
the day Wednesday through Friday. Once again, the threat of severe
weather appears to be very low at this time, and lightning and
strong wind gusts will represent the primary hazards.

Also, as the chance of rain lowers next week, temperatures will
warm back into the 90s. Heat index values will have to be
monitored as they reach the mid to upper 90s to near 100 degrees
in spots.

.Spotter Information Statement...

Spotter activation may be needed today and later tonight to
Saturday, due to the threat of isolated strong to severe storms.
