.SHORT TERM...
(Today and tonight)
Issued at 1226 AM CDT Thu Aug 13 2026

Continued hot and dry conditions continue as the upper level ridge
dominated the area. Two concerns starting to develop, as drying of
vegetation is allowing temperatures to creep up a few degrees.
This puts the central and northern Big Country into the 104-105
degree range, with heat index values about the same. Already have
a Heat Advisory in effect for areas north of I-20 and will
maintain this through the afternoon hours.

Second concern is the developing fire weather conditions in this,
as previously mentioned, a secondary fire weather season for West
Central Texas. Wind speeds have started to creep up, with Abilene
seeing wind gusts well over 30 mph on Wednesday. San Angelo was
around 30 mph. With humidity values at 25% or lower and with the
continued heat/dry, increasing wind speeds will lead to an
increase in the fire weather threat today. Have issued a Rangeland
Fire Danger Statement for this afternoon.

.LONG TERM...
(Friday night through next Thursday)
Issued at 1100 PM CDT Wed Aug 12 2026

Hot and dry conditions are expected to persist through mid next
week, as high pressure remains steadfast over the region through
the long term forecast. Little change in temperatures is expected
with our daily highs and lows. Afternoon highs are expected in
the mid 90s up to around 102 degrees, and overnight lows in the
70s. South winds will continue and remain breezy through the end
of the week, then decrease slightly over the weekend and into
next week as the surface pressure gradient weakens to some extent.
