.DISCUSSION...
Issued at 134 PM CDT Sun Aug 31 2025

Easterly low-level flow across our area today signals the presence
of high pressure to our north. Flow aloft turns out of the north
and northwest with western CONUS ridging and eastern CONUS
troughing which will persist through this week.

The flow aloft should amplify quickly as an upperl-level ridge
over the Rockies elongates and deep troughing digs over the
eastern half of the CONUS. Upper-level heights in the core of this
trough will be about 2-4 standard deviations below normal for
this time of year - keeping temps from rebounding to strongly.
Earlier guidance for below normal temperatures has backed off with
cooler surface air waiting largely until next weekend.

The broad trough axis over the eastern half of the country still
means disturbances could bring some chance for showers or storms
to the region, and Tuesday into Wednesday currently looks to be
the best time range for that to occur with a passing shortwave in
the broader trough. Timing and strength of the wave details could
adjust this window for rainfall. /NF/
