..PREV DISCUSSION... /ISSUED 1130 AM CDT Wed Sep 10 2025/

....High Plains/Front Range...
As the upper ridge tends to abate/shift away, the region will begin
to be influenced by the upper trough over the West. While some
stronger storms could occur across a relatively broad north-south
extent of the High Plains, portions of eastern Wyoming and the
northern Colorado Front Range and immediately adjacent High Plains
are expected to be influenced by somewhat stronger mid-level
westerlies (25 kt), aside from steep lapse rates and moderate
buoyancy. Low severe probabilities have been introduced for what
should be an isolated/relatively marginal severe potential later
this afternoon into evening.

....Great Basin/Interior West...
The region will be influenced by a belt of stronger cyclonic flow
aloft preceding the upper low centered over northern California.
Adequate moisture, steep lapse rates, and stronger deep-layer winds
could allow for some storms to produce gusty winds and small hail,
mainly across central/northern Nevada into southwest Idaho.
