Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0453 PM CDT Wed Jul 02 2025

Valid 041200Z - 101200Z

...Day 3/Friday...
A negatively tilted short-wave trough and attendant mid-level wind
maxima entering into the western U.S. on Day 3/Friday will increase
fire weather concerns across much of the Great Basin. The stronger
dry, southwest flow will scour out remaining monsoon moisture across
the much of NV and southwest UT resulting in a deep, well mixed
boundary layer and low surface relative humidity. In addition,
widespread showers and thunderstorms ahead of the trough will affect
portions of eastern Oregon and Northern Rockies region.

...Day 4-8/Saturday-Wednesday...
A mid-level trough will lift into the Northern High Plains on Day
4/Saturday with a broad but reduced southwest flow pattern
continuing to push remaining monsoon moisture and associated high
terrain convection along and east of the Continental Divide by Day
5/Sunday, mitigating the threat of new lightning ignitions for much
of the Intermountain West. A building mid-level ridge over the
Desert Southwest will support climbing temperatures to above
seasonal averages across much of the West starting early next week.
This pattern could also usher in another round of monsoon moisture
into the Lower Colorado River Basin and southern California as early
as Day 5/Sunday, although enough forecast uncertainty exists to
preclude critical probabilities of dry thunderstorms at this time.
