.DISCUSSION...
Issued at 225 AM CDT Tue Oct 20 2026

Dry weather will persist through the upcoming week as high
pressure continues to hold sway across the eastern half of the
CONUS. Within the dry airmass, daytime temperatures will continue
to trend above normal, with mid to upper 80s increasingly common
through Friday. By this weekend, a shift to more easterly low
level flow, resulting in a wedging effect around the
Appalachians, will begin to cut in to daytime highs somewhat.
Morning lows will remain seasonably cool through the next several
days.

Fire weather will remain the primarily concern over the upcoming
week, given antecedent dry ground conditions/fuels (daily max
ERCs in the 90th+ percentile) with RHs falling below 30 percent
each afternoon and at times falling into the teens. The saving
grace preventing a more critical situation worthy of red flag
products will be relatively light wind each day, which should help
control spread of fires that do develop. Nevertheless, caution
should continue to be exercised with any outdoor burning over the
next several days. Heed local burn bans, which continue to be
added in new areas. If we begin to see signs in later forecasts
of stronger wind on any upcoming days, messaging may need to be
elevated accordingly. /DL/
