Day 3-8 Fire Weather Outlook

Valid 051200Z - 111200Z

...Day 3/Saturday...
A mid-level short wave trough will lift into the Montana and
northern High Plains through Day 3/Saturday. Widespread wetting
rains are expected across much of the Northern Rockies while
lingering southwest flow will present a fire weather threat to
portions of southeastern NV/southwestern UT. Elevated mid-level
winds along with a well-mixed boundary layer will support breezy and
dry conditions for the southern Great Basin on Day 3/Saturday, where
40 percent critical probabilities have been added.

...Days 4-8/Sunday-Thursday...
A building Four Corners high along with a quasi-stationary mid-level
low offshore of northern CA will support a persistent dry, southwest
flow pattern over the Southwestern U.S. and Great Basin Region from
Day 4-7/Sunday-Wednesday. A primary impact of the building mid-level
ridge will be increasing heat across the Western U.S., promoting
drying of fuels across the region while southwest aloft keeps
monsoon moisture and associated showers and thunderstorms confined
to the Continental Divide and southern Arizona. Ensemble guidance
suggests a slight shift westward of the Four Corners high towards
the lower Colorado River basin midweek, potentially inviting a push
of monsoon moisture into Southern California and Great Basin Days
7-8/Wednesday-Thursday. However, uncertainty remains high enough to
preclude critical probabilities for dry thunderstorms at this time.
