.DISCUSSION...
Issued at 1209 AM CDT Tue Sep 30 2025
High pressure continues to hold a firm grasp across much of the mid
south early this morning. Latest deterministic guidance shows
ridging will stay in place through Tuesday. By Tuesday night into
Wednesday, a weak upper disturbance will round the periphery of
the upper trough over the east coast coupled with an increase in
surface moisture bringing a chance for an isolated shower or
thunderstorm on Wednesday to parts of Arkansas. As previously
stated, confidence model solutions for Wednesday remains low.
As the upper trough over the east coast moves off shore, an upper
low/inverted trough forms over southern AL/N FL sometime on
Friday into the weekend. The GFS solution shows the low/inverted
trough meandering northwest into the mid south by this weekend and
may bring some isolated POPs to the eastern part of the state.
The ECMWF solution shows the upper low/inverted trough drifting
westward along the gulf coast with no sensible impacts to weather
in the state. At the end of the upcoming weekend into early next
week, both the ECMWF and GFS solutions show a deepening trough
over the western US, but vary on the eastward progression of the
trough. This will allow south to southwest flow to set up over
Arkansas with continued dry conditions and light winds.
Temperatures will continue to be seasonally warm for late
September into early October averaging roughly 4 to 6 degrees
above normal for climatological highs each afternoon. Lows each
night will range from the upper 50s to lower to mid 60s each night
across the state through early next week. Dry conditions are
expected to persist beyond Wednesday through the rest of the
period.
