.DISCUSSION...
Issued at 1220 PM CDT Sat Sep 26 2026

Tonight through next Friday...While some fluctuation in these
features will exist across the region, high pressure at both the
surface and aloft will overall continue to dominate the weather
across the forecast area through much of this forecast period.
This`ll continue to result in quiet weather across the CWA through
the majority of the period.  Unfortunately, high temperatures will
gradually warm a few degrees each day across the area, but through
mid-week the drier airmass currently over the region will remain
present under easterly flow.  Despite the warming afternoon high
temperatures, this dry air will allow for pleasant overnight lows as
they generally range from the upper 50s to middle 60s through
Tuesday night.

During the mid and latter portions of the week, moisture will subtly
begin increasing again across the region as southerly flow at the
surface and aloft returns.  In turn, rain chances will also begin
increasing each afternoon Wednesday through Friday as the
aforementioned high aloft steadily slides east of the Lower
Mississippi River Valley through week`s end.  Increased troughing to
the west across the southern plains states could yield a cold front
that may try to shift east into the forecast area sometime next
weekend.  This would allow rain chances to persist across the CWA
during that time. /19/
