Flash Flood Warning 52, NWS Little Rock, AR

Area Forecast Discussion
National Weather Service Little Rock AR
247 PM CDT FRI JUN 17 2016

.Short term...Tonight through Sunday night

Latest surface analysis place a weak and rather diffuse frontal
boundary roughly along a line from Harrison to Clinton to Searcy.
Remnants of the MCV from this morning is muddling things up a bit
with boundary a bit difficult to really find. Aforementioned feature
from this morning brought localized flooding issues to Marion
county. Please refer to the local storm reports for the specifics.

Front expected to continue moving from the northeast towards the
southwest this evening and tonight, clearing the state around
sunrise on Saturday. Scattered showers and thunderstorms will
accompany the boundary and the possibility of some strong storms
cannot be discounted.

However, the left overs from the MCV which are in central Arkansas at
this time may limit the severe potential to a certain extent.
Intense cluster of severe thunderstorms is currently located along
the boundary over northern Mississippi and while this batch is moving
away, potential still exists further east as the afternoon
progresses.

Slightly cooler and drier air air will then spread over the area in
the wake of the boundary for the remainder of the period. While both
temperatures and dew points will be lower, it will be still be warm
but much more representative of what conditions should be in mid
June. As such, the heat advisory will be allowed to expire this
evening with no reason to reissue needed.
&&

.Long term...Monday through Friday

Surface high pressure is expected to move east of Arkansas on
Monday... ushering southerly winds and humid Gulf air back across
the state. Heat index values will likely approach 100 degrees across
Arkansas Monday afternoon with highs in the lower 90s and dew points
in the lower 70s. Upper level ridging should provide enough weak
forcing for subsidence to keep showers and thunderstorms suppressed.

On Tuesday the upper level ridge is expected to slide to the
southwest as a strong upper trough moves southeast over the Great
Lakes region. With warm and humid conditions still in place across
Arkansas...this may be enough to allow for some isolated
thunderstorms to develop during the peak heating hours of the day.
High temperatures and humidity are expected to be similar to Monday
for Tuesday afternoon...but went ahead with broad brushed 20 pops to
account for the increased likelihood of thunderstorms.

On Wednesday the large upper trough is expected to dig south over
the southeastern CONUS. This should send a cold front slowly
southwest across Arkansas Wednesday morning...possibly stalling out
across the state Wednesday afternoon. The front is expected to serve
as a focus for rain shower and thunderstorm development on
Wednesday...so will carry a 30 pop in the forecast for now until
confidence increases as we get closer to the middle of next week.
Scattered thunderstorms look likely in this scenario wherever the
front stalls out...but models do not consistently stall the front
out in the same area.

Thursday and Friday...The forecast is more or less contingent upon
what happens with the cold front on Wednesday...including how much
convection along the front may affect its position Wednesday
afternoon into Wednesday night. Assuming the front is in southwest
Arkansas Thursday afternoon...went ahead and kept a 20 pop in the
forecast for the southwestern CWA at this time. Left Friday dry for
now as most model guidance indicates drier air behind the front will
be in place across Arkansas by that time.
