   Valid 031200Z - 041200Z

   An Elevated area was introduced over far southwest ID and much of
   northeast NV. The latest forecast guidance has moved the exit region
   of a jet streak, associated with the aforementioned upper-level
   trough, slightly farther east on Day 2/Wednesday afternoon. This
   will lead to stronger winds (sustained near 15-20 mph at the
   surface) over the drawn area combined with well above normal
   temperatures and resultant RHs down to 10-15% during peak heating
   also allowing for a well-mixed boundary layer. While some green-up
   is in place over the area, enough continuity of very dry fuels
   coincident with the previously mentioned weather conditions will
   exist to warrant a small Elevated fire risk over this portion of the
   western Great Basin.

   .PREV DISCUSSION... /ISSUED 1234 AM CDT Tue Jun 02 2026/

   ...Synopsis...
   Weak and diffuse upper-level troughing will continue over the
   Southwest, with an upper-level trough moving into the northwestern
   US. Winds will increase across much of western/northern Nevada into
   southern Idaho ahead of the upper-level trough and associated dry
   cold front and overlap a dry airmass. Elevated to locally critical
   winds/RH are likely across these areas, but recent rainfall should
   mitigate fire weather concerns, with this acting as more of a curing
   event. 

   Isolated to scattered mixed wet/dry thunderstorms are likely again
   across portions of far eastern Arizona into western New Mexico and
   southern Colorado. Storms east of the Divide will be mostly wet with
   drier storms along/west of the Divide. However, given the weak
   steering flow, storms are likely to linger longer over areas,
   especially on the higher terrain. Additionally, slightly deeper
   moisture may work its way into portions of eastern Arizona,
   especially southeast Arizona, which would also limit the potential
   for drier thunderstorms. Fuels remain dry, but some areas will have
   a second consecutive day of thunderstorms, which may help limit
   ignition potential. 

   The upper-level ridge will begin to flatten over the Upper Midwest
   and Great Lakes, but the stronger winds will be displaced from the
   lowest RH. Regardless, fuels remain very dry across these areas
   (90th+ percentile) amid above normal temperatures and pockets of RH
   below elevated criteria.

   Day 3-8 Fire Weather Outlook

   0451 PM CDT Tue Jun 02 2026

   Valid 041200Z - 101200Z

   ...Synopsis...
   An upper level shortwave over the Canadian border will continue an
   eastward progression on Day 3/Thursday with otherwise weak flow over
   the southern half of the CONUS. A more significant trough over the
   northern Pacific will approach the west coast on Day 4/Friday,
   leading to increased winds across the Pacific Northwest and adjacent
   areas. This system continues to move through the northwestern CONUS
   on Day 5/Saturday before lifting northeast on Day 6/Sunday. In the
   wake of this trough, a cold front is anticipated to spread across
   the Pacific Northwest and into the northern Great Basin, temporarily
   dropping daytime temperatures below normals over the western third
   of the US.

   ...Portions of the Southwest and Great Basin...
   ...Day 4-6/Friday-Sunday...
   Increasing southwesterly mid-level flow ahead of the approaching
   upper-level trough will encourage a dry and breezy environment to
   emerge across the Great Basin and Southwest by Day 4/Friday. 40%
   Critical probabilities have been introduced where extended guidance
   and ensemble probabilities denote a broad area of low RH and strong
   winds. This potential will become more widespread and expand farther
   east on Day 5/Saturday and continue on Day 6/Sunday as the
   upper-level trough progresses. Higher probabilities will likely be
   needed if model trends continue to hold past Day 4/Friday.
