.DISCUSSION...
Issued at 245 AM CDT Mon Sep 14 2026

Today, few to scattered afternoon showers and thunderstorms are
possible across mainly Cntrl/S/SE AR associated with abundant low-
level moisture coupled with peak diurnal heating. The main
thunderstorm hazard with any of the stronger convection would be
damaging straight-line winds. Otherwise, dry and hot conds can be
expected across the state. Highs today and Tuesday should range from
the mid 90s to around 100 degrees. Factoring in the humid airmass in
place and heat index values ranging from 105 to 110 are expected
each afternoon across a large part of the state. Given this, a Heat
Advisory is in effect across all but NW and N-Cntrl AR through at
least Tuesday evening.

Heading through middle-to-late part of this week, a stout upper
ridge will become re-established across the Srn CONUS. During this
time, the center of high pressure will meander about the region
between features to the W and E of the ridge axis. Underneath the
ridge, highs will range from the mid 90s to around 100 degrees each
day. Rain chances will remain minimal, or spotty at best, with heat
index values topping out between 95 and 110.

As we progress through middle part of September it becomes
increasingly difficult to reach 100 degrees due to decreasing
overhead sun angle, expected increase in average precip, and
decreasing amount of daylight with each passing day. To oppose these
natural cooling expectations one would expect, a strengthening and
amplifying ridge on the order of ~597-600 decameters will remain in
place across the region. For those curious about climatological
average temps for this time of year, Little Rock - Average Low 64,
Average High 86; Pine Bluff - Average Low 64, Average High 87;
Harrison - Average Low 59, Average High 82. In summary, average
highs and lows are expected to range from 10-15 degrees above
climatological average through Saturday.

While Sunday is pretty far out in the long term, there are some
indications that the ridge could shift Ewrd as an upper trough moves
into the nations mid-section. If this happens, rain chances could
increase locally while simultaneously lowering temps to end the
period.

.AVIATION...
(00Z TAFS)
Issued at 617 PM CDT Mon Sep 14 2026

VFR conditions will persist through the forecast period. Isolated
showers and thunderstorms across the southern half of Arkansas
will dissipate within an hour or two of sunset. Light and variable
winds will persist during the overnight into early Tuesday. Expect
mainly light south to southeast winds at most terminals but an
isolated gust or two is not out of the question at normal terminals.

Isolated showers and thunderstorms are possible mainly across
central and southern Arkansas terminals on Tuesday afternoon, but
confidence is too low to place in TAFs at this time.
