.SHORT TERM...
(Today through Friday)
Issued at 1152 PM CDT Wed Aug 19 2026

Exceptional heat continues to round out the workweek with
no end in sight to widespread triple-digits. Although the mid-
level high pressure center has retreated to the west, 500mb
heights remain near 595dam, and no mechanism exists in the near
term that will allow the above normal heat to abate. The main
change from previous forecasts, however, was to include low PoPs
both today and Friday as isolated convective activity will be a
possibility for the first time in several days. Modest northerly
flow along the eastern periphery of the ridge will send a weak
surface front/tough towards the Red River later today, and weak
convergence along this feature could support isolated
thunderstorms across our northeastern zones from late this
afternoon into the evening. Coverage would likely be about 10% or
less. A second weak impulse will round the eastern side of the
ridge on Friday, and additional isolated/scattered thunderstorms
will be a possibility across much of the area. We`ll introduce
PoPs of 10-20% through Friday afternoon, but with limited
coverage, most of the CWA will remain rain-free. This convective
activity will do little to alleviate heat, with readings still
climbing to near 105 both afternoons. The hot temperatures and 40+
degree dewpoint depressions will allow any convective activity to
produce strong downburst winds during this time frame. Otherwise,
the continued low humidity will increase the potential for grass
fire starts, and these occurrences may become more common due to
lightning strikes from isolated thunderstorm activity.

.LONG TERM...
(Friday night through next Wednesday)
Issued at 1152 PM CDT Wed Aug 19 2026

Following our couple days of convective chances to end the
workweek, the upper ridge axis will expand eastward again this
weekend with temperatures of 103-108 prevailing through the
extended forecast period. Rain chances look to be quite limited
during this time given the strengthening subsidence accompanying
building heights aloft. Isolated storm chances may return
mid/late next week as the ridge axis is forecast to break down
slightly, but this would likely still be isolated coverage of no
more than ~20%. Additional heat headlines will be necessary for
most/all of the CWA through at least the middle of next week.

.AVIATION...
(06Z TAFS)
Issued at 1152 PM CDT Wed Aug 19 2026

VFR will prevail through the period with a south wind around 10
kt and some daytime gusts to 15 kt. A weak surface front will
encroach on the Red River late this afternoon and evening, with
isolated convective activity occurring along it. At this time, any
showers or thunderstorms are expected to remain north/northeast
of the TAF sites through the forecast period.

.SPOTTER INFORMATION STATEMENT...
Spotter activation is not expected at this time.
