(Today and tonight)
Issued at 154 AM CDT Thu Sep 18 2025
High pressure remained the predominant feature this morning ahead of
a cold front located over the Panhandle. Across west central Texas
skies were partly cloudy with temperatures in the upper 60s to low
70s.  Ahead of the frontal boundary, a couple of weak mesoscale
boundaries were drifting southward into the Big Country this
morning.  At this point, chances for rain with these features are
low, given the relatively dry airmass in place.  Mid-level moisture
looks to increase today as the upper-ridge over the region starts to
break down, resulting in some high clouds by late afternoon or
evening.  Otherwise, conditions today will be fairly similar to the
past few days with southeasterly winds between 5-10 MPH. Despite the
ridge starting to diminish, there is no significant change in
airmass so high temperatures today should be in the upper 80s to low
90s again. Overnight, low temperatures look to be in the upper 60s
to around 70.

(Friday through Wednesday)

A ridge of high pressure will sit across northern Mexico over the
next few days. This will leave our area under the influence of this
system. This means hot and dry conditions will largely continue
through Friday.
Then, an embedded disturbance will move across the northern Texas
late Saturday. This may be enough to support a low chance for an
isolated rain shower or thunderstorm on Saturday evening through
Sunday. Thunderstorm chances (20-30%) will largely be limited to the
I-20 corridor and northward given the track of this disturbance.
By Monday, both the GFS and the ECMWF indicate a low pressure system
developing across the Plains. However, the GFS keeps the low
centered further to the north, which will limit rain chances given
the track of the low pressure center. Given the differences in model
tracks, it seems reasonable to keep rain chances limited a bit next
week given the uncertainty. This may change if higher levels of
consistency are seen in future model runs. Regardless, what seems
most likely is we see a weak cold frontal boundary move into the
area on Monday and Tuesday. Slightly cooler temperatures will
result, but highs will still remain in the upper 80s.
