.DISCUSSION...
Issued at 1235 AM CDT Tue Sep 29 2026

A mid-level ridge axis will shift east over the next day or two
and sfc ridging will move from the Great Lakes to the Mid-Atlantic
coast which will provide a return to srly flow over the state.
The combination of these two features will provide basically no
rain chances and well above normal temperatures. High temperatures
are expected to peak between Wed-Thu with readings around 10
degrees above normal for late September/early October.

The main focus of the forecast continues to be a slow moving H500
low over the SW US expected to interact with an anomalously high
moisture plume from the remnants of Pacific Hurricane Polo. As the
storm system makes slow progress eastward it will encounter
resistance from ridging across the SE US.

As the mid-level low drifts east it will contribute toward a
multi-day heavy rainfall event that will impact portions of the
Southwest as well as Oklahoma and Texas. By later this week the
H500 low will lose intensity, open and be absorbed by northern
stream enhanced zonal flow.

What this means for Arkansas and nearby areas is rain is expected
to slowly move in from west to east across the state later this
week and into Saturday as a sfc cold front approaches. But, while
previous model runs indicated widespread heavy rainfall potential
was expected across the state, recent data is beginning to align
on a lower QPF event for the Natural State. The main focus for
more than 1-2 inches of rain remains across western Arkansas with
precip amounts tapering off and becoming less uniform toward the
MS River.

While several inches of rain would go a long way toward improving
the state`s current high wildfire danger and drought conditions,
any rainfall is welcome at this point. Accompanying the rain
chances and in the wake of the cold front will be several days of
much cooler temperatures. Below normal temperatures may even be
seen for several days.
