.SHORT TERM...
(This evening through Friday)
Issued at 154 PM CDT Thu Sep 24 2020

Patchy fog will be possible for a few hours around sunrise for
mainly Kimble County in the Northwest Hill Country. A surface
ridge will weaken and shift southward tonight as a lee trough
develops over the Panhandle and far west Texas. Light winds today
and tonight will shift around to the southeast by morning and
increase in speed. This should keep fog confined to just the far
southeastern areas where winds will still be light. The rest of
the area should stay clear and dry tonight and tomorrow. Lows
tonight will drop into the 50s, with highs tomorrow warming into
the lower 90s under sunny skies.

.LONG TERM...
(Friday night through next Wednesday)
Issued at 236 PM CDT Thu Sep 24 2020

The weekend is still looking much warmer than normal. Broad, weak
upper level troughing over eastern Texas is expected to evolve
into a weak upper low over eastern Texas by Saturday. To the west,
persistent ridging over the southwestern U. S. will result in
warming 850mb temperatures across western Texas and our forecast
area, with the thermal ridge axis expected to spread eastward into
our area on Sunday, resulting in widespread 90+ degree
temperatures, with triple digit heat not out of the question,
especially for the Concho Valley.

Sunday night into Monday, both the GFS and ECMWF show a strong
cold front moving through the area, cooling temperatures off
significantly for Monday. Both models also show precipitation
developing along/behind the front as it moves through, but most of
these showers and storms are expected to be east of our area.
Behind the front on Monday, windy conditions are also likely, with
strong northerly winds just off the surface indicated in the GFS
and ECMWF. Highs Monday will be in the 70s to around 80 degrees,
and could be cooler in any areas that see cloud cover hang around
most of the day. Temperatures will rebound back into the upper 80s
to around 90 degrees by Wednesday, with dry weather.

VFR conditions will continue across West Central Texas terminals
for most of the next 24 hours. Brief fog dropping visibilities
into MVFR range will be possible across the southern terminals
right around sunrise Friday morning, but should be brief. A little
more consistent southerly winds are expected but remaining at
less than 10 knots.
