.SHORT TERM...
(Today through Friday)
Issued at 1246 AM CDT Thu Oct 2 2025
A mid level ridge from the southern Plains to the Ohio Valley and a
mid level low over the central and eastern Gulf persist today into
Friday. Seasonal PWs of 0.9 to 1.2 inches over our area and
subsidence will inhibit rain chances today. However, mainly the
HRRR shows a few showers. Subtle changes in the mid levels are
indicated for Friday. The southern Plains portion of the ridge lifts
a little to the north while the low drifts a little to the west.
This allows an area of above average PWs of 1.2 to 1.5 inches
currently over the lower Mississippi Valley and Central Gulf Coast
to move west to over our area. Subsidence weakens and with heating,
isolated showers and perhaps a thunderstorm are possible along
and east of the US 281 corridor Friday afternoon as noted in all
Hi-Res models. Will go above NBM guidance with 10-20 POPs.
Temperatures remain well above early October averages with lows
warming a little.

.LONG TERM...
(Friday night through Wednesday)
Issued at 1246 AM CDT Thu Oct 2 2025
This weekend, mid level troughing moves over the western states and
northern Plains shoving the ridge to over mid Atlantic region and
drawing the low to over the western Gulf. Some drying will keep rain
out of the forecast, except for slight chances each afternoon with
heating and the seabreeze near the Coastal Plains where the deeper
moisture lingers. Early to middle of next week, western troughing
lifts north absorbing the Gulf low and allowing the ridge to expand
back to the west to over the Plains. This allows deeper moisture to
flow over our area with slight chances of showers and perhaps a
thunderstorm over most areas. Temperatures remain well above early
October averages.
