.DISCUSSION...
Issued at 246 AM CDT Sun Oct 5 2025
Today through Saturday...Weak low pressure aloft will position
itself over the Lower Mississippi River Valley today.  With it,
increasing moisture across the region will yield some increasing,
and much needed, rain chances across the forecast area this
afternoon, mainly in the form of isolated to scattered showers and
thunderstorms lifting up from the south. Much of this activity will
dissipate during the evening hours, but some isolated showers will
remain possible overnight into Monday morning.
Although this mid/upper level low pressure system erodes heading
into the new work week, moisture associated with it will linger
across the forecast area through mid-week.  This will continue to
result in rain chances remaining in the forecast, especially during
the heat of the afternoon, through at least Wednesday. This is when
a fast moving cold front is progged to sink south into and through
the region.
In this front`s wake Thursday through Saturday, high pressure at the
surface will quickly build southeast into the Lower Mississippi
River Valley, with high pressure aloft building southwest along the
north central gulf coast.  Not much of an airmass change is
currently expected to accompany this frontal passage, as only some
slightly drier air will advect into the region. Still, somewhat less
humid conditions will exist as temperatures hover at to just above
the norm for this time of year late in the week. /19/
