Area Forecast Discussion
National Weather Service Little Rock AR
1229 PM CDT Sun Aug 1 2021

.UPDATE...

Updated to include the 18Z aviation discussion below.

&&

.AVIATION...

All sites will begin the period in VFR conditions. Take note that
middle and southern terminals will be experiencing scattered
showers/t-storms throughout the period. KADF, KHOT, and KHRO will
see a significant reduction in visibility from low stratus/fog and
lowering cigs between 10Z and 13Z where a decline in flight category
is expected to be implemented as low as IFR. Conditions will improve
near the end of the forecast period.

&&

PREV DISCUSSION...(ISSUED 313 AM CDT Sun Aug 1 2021)

SHORT TERM...Today Through Monday Night

A cold front is dropping south into the state early this Sun
morning...with some scattered/isolated SHRA/TSRA ongoing
along/behind this front mainly along/just north of the MO/AR border.
This front will continue to drop south through the rest of the state
by this afternoon/evening...with chances for SHRA/TSRA increasing
from north to south throughout the day as a result.

While the overall threat for severe weather looks to remain
limited...a few strong to briefly severe storms could be seen
through this afternoon/evening. The best chances for seeing any
strong/severe storms will be across the SRN third of the state this
afternoon where instability levels will be much higher due to hotter
temps.

Speaking of the hotter temps...expect highs to warm into the
mid 90s across this SRN portion of the state by early this afternoon
before the front arrives. These hotter temps combined with dewpts in
the 70s...expect heat index values to likely once again exceed 105
deg for many locations across the SRN portion of the CWA. As a
result...will keep the Heat Adv in place for this afternoon in this
region of the state. Further north...highs will be cooler in the
upper 70s to upper 80s...and dewpts will be more comfortable in the
low to mid 60s by this afternoon...especially across NRN AR.

By tonight...the cold front will slow across SRN AR...with POPs
remaining elevated across the SRN third/half of the state. These
higher POPs will eventually decrease from north to south by late Mon
afternoon as the front drops south of the state...and more
stable/drier/cooler air filters into the state. These drier/cooler
conditions will remain in place to wrap up the short term
period...and persist into the first part of the long term
period...with below normal conditions expected.

LONG TERM...Tuesday Through Saturday

Upper level high pressure will be centered over the western U.S. to
begin the long term period with an upper trough over the eastern
half of the country. This pattern will continue through the middle
of the week. The upper ridge begins moving east on Thursday and by
Friday it will be creeping into western Arkansas. The upper high
will be over Arkansas on Saturday.

The cold front will be south of Arkansas Tuesday with high pressure
over the state. This will bring more comfortable temperatures to the
area with drier air. The front will stall near the Gulf Coast
Wednesday through Friday. No rain chances are expected through much
of the extended period. Only will include a slight chance of showers
and thunderstorms in the far south on Saturday as the warm front
moves into the south part of the state. Highs in the mid to upper
80s will be common Tuesday and Wednesday, but low to mid 90s return
on Friday. Lows will be in the 60s until Friday night when lower 70s
return to the south and east.
