.PREV DISCUSSION... /ISSUED 0201 AM CDT Wed Jul 20 2022/

...Synopsis...
On the periphery of the strong western US ridge, an upper-level
trough will move onshore across the Pacific Northwest Thursday.
Stronger mid-level flow will gradually develop inland over the
northern Great Basin and Rockies. At the surface, a weak cold front
will move south stalling across the central High Plains. Gusty
northwest winds will be possible along and behind the front, along
with low RH. While no fire weather areas will be added, locally
gusty winds and dry conditions will continue to support marginal
fire weather concerns.

...Northern Great Basin into the central Rockies...
As the upper trough moves further inland through the afternoon,
increasing southwesterly flow should support a gradual uptick in
downslope winds off the higher terrain. While not overly strong,
occasional gusts to 20 mph will be possible. Given RH values below
20% and very dry fuels, some localized fire weather threat will
likely develop. Gusty winds may linger overnight behind the
slow-moving cold front. While RH values should begin to recover, the
gusty winds may prolong localized fire weather concerns for a few
hours after sunset.

...Southern Plains...
While slightly cooler than the previous days, warm temperatures and
low surface RH will again persist beneath the strong upper ridge.
Locally gusty winds near the stalled front and beneath high-based
afternoon/evening storms, capable of occasional lightning strikes,
may contribute to locally elevated fire weather concerns given
drought-stricken fuels.
