A large-scale trough will amplify over the western CONUS on Days
3-4/Thursday-Friday, before evolving into a closed midlevel low over
the Four Corners region into Day 6/Saturday. Ahead of the trough,
strong deep-layer south-southwesterly flow will overspread the Great
Plains on Day 3/Thursday, while the surface pressure gradient
tightens between a deepening lee trough over the High Plains and
expansive surface anticyclone over the eastern CONUS.
...Day 3/Thursday - Northern/Central Plains...
The tightening pressure gradient and shallow boundary-layer mixing
into the strong deep-layer flow will favor an expansive area of
strong/gusty southerly surface winds across the Great Plains and
Upper/Middle MS Valley. While the degree of boundary-layer
heating/mixing and related RH reductions are uncertain (especially
with northward extent), confidence in at least 25-percent RH
overlapping the strong/gusty winds is high enough to introduce a
70-percent Critical area.
...Day 4/Friday - Northern/Central California...
On the backside of the amplified large-scale trough, strong
deep-layer northerly flow will develop across California on Day
4/Friday -- where a relatively warm/dry air mass will be in place.
This will promote elevated to locally critical fire-weather
conditions.
