.SHORT TERM...
(This afternoon through Sunday)
Issued at 1200 PM CDT Sat Sep 20 2025
West central Texas will remain under somewhat weak northwest flow
tonight into Sunday. High resolution CAMs show scattered convection
developing later today to our northwest across parts of the Texas
panhandle southeast into northwest Texas. Some of these storms
could eventually reach parts of our northern Big Country area
north of I-20 later tonight, so have kept a 20% chance for showers
and thunderstorms going in that area. In addition, a weak
shortwave trough will move through the southern plains Sunday,
bringing another chance for isolated to scattered showers and
thunderstorms. While the best chances will be north of I-20, there
is a low chance for some of these storms to reach as far south as
the Concho Valley, so have added some 20% PoPs south of I-20 as
well for Sunday afternoon. Otherwise, temperatures will continue
to be warm, with lows tonight in the mid 60s to near 70, and highs
on Sunday in the mid to upper 90s.

.LONG TERM...
(Sunday through Friday)
Issued at 125 AM CDT Sat Sep 20 2025
An embedded disturbance will move across northern Texas on
Sunday. This may be enough to support a low chance for an isolated
rain shower or thunderstorm through Sunday. Thunderstorm chances
(20-30%) will largely be limited to areas near the I-20 corridor
and northward given the track of this disturbance.
By Tuesday and Wednesday, both the GFS and the ECMWF indicate a
low pressure system developing across the Plains. The GFS and
ECMWF are showing a similar solution tracking the low across
Kansas, which is a bit further north than yesterday`s model runs.
Regardless, we may see a weak cold frontal boundary move into the
area on Tuesday night into Wednesday because of this system. This
frontal boundary will serve as a focal point for scattered
thunderstorms (30% chance) across our area as it moves through.
Slightly cooler temperatures will also result, but highs will
still remain in the middle to upper 80s.

.AVIATION...
(18Z TAFS)
Issued at 1200 PM CDT Sat Sep 20 2025
Generally VFR conditions are expected to prevail at all sites
through late Sunday morning, with south to southeast winds around
10 knots. Although there is a chance for TSRA north of I-20 later
tonight, confidence is not high enough in coverage of this
activity to introduce a mention at KABI at this time.
