Expanded the elevated southwestward through Utah and into far
northwest Arizona and southern Nevada. While conditions will not be
much different from climatology, they are expected to be similar in
Utah and Northwest Arizona as they will be in Wyoming. Therefore, an
expansion of the elevated was warranted. 

In addition, added an elevated area for portions of eastern Idaho
where it appears winds will be around 15 to 20 mph with RH around 12
to 18 percent this afternoon.

...Synopsis...
Upper-level ridging will continue to strengthen and amplify over the
western CONUS today. Much of the Intermountain West will remain
hot/dry, and large-scale flow will be relatively weak across the
much of the region. However, some residual stronger mid-level flow
will remain over the northern Rockies/vicinity, and a weak mid-level
shortwave trough is forecast to move over the northern Rockies as
well.

An elevated area was added across portions of southern and central
Wyoming. West-southwest sustained surface winds of 12-20 mph with
gusts of 25-30 mph and RH values of 8-15% are expected this
afternoon and into the evening across the area. Additionally, very
deep (10,000+ ft), dry, and unstable boundary layers will develop.
This will be the fifth consecutive day of dry/breezy conditions with
ERCs rising across portions of southern/western/central Wyoming
(70-90th percentiles).

.PREV DISCUSSION... /ISSUED 0139 AM CDT Mon Aug 19 2019/

...Synopsis...
The upper-level ridge over the western CONUS will continue to
amplify into western Canada tomorrow with an upper-level shortwave
trough approaching the Pacific Northwest. Subtropical moisture will
begin to move into the Southwest as the ridge builds and into
southern Montana/northern Wyoming with easterly low-level flow
extending westward from the northern Plains. Isolated dry
thunderstorms may develop across southern Montana and northern
Wyoming. However, fuel conditions and uncertainty regarding
thunderstorm coverage preclude introducing an isolated dry
thunderstorm area at this time.
