1217 AM CDT Sat Jul 12 2025
Valid 121200Z - 131200Z
...NO CRITICAL AREAS...
...Synopsis...
High pressure across the western US will continue to keep winds
mainly light and terrain driven where fuels are the driest Saturday.
Moisture will increase across west-central Colorado, with PWs
approaching 0.60-0.75". A mix of initially dry/wet thunderstorms
will be possible, though the dry thunderstorm risk should remain too
localized to include areas with this outlook.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1218 AM CDT Sat Jul 12 2025
Valid 131200Z - 141200Z
...Synopsis...
A mid-level shortwave will move across the periphery of the western
ridge on Sunday. This will bring an increase in westerly winds
across the Cascades in central Washington and Oregon. Winds will
largely remain Elevated (at around 10-15 mph) but some locally
Critical conditions will be possible in the Cascade gaps. Fuels in
this region are critically dry, with ERCs exceeding the 90th
percentile for dryness.

Day 3-8 Fire Weather Outlook

0233 PM CDT Fri Jul 11 2025
Valid 131200Z - 191200Z
Upper ridging should dominate the western into south-central CONUS
through at least early next week, before the ridge flattens through
the remainder of next week. Multiple mid-level impulses will crest
the ridge through early next week, providing enough upper support to
induce dry and windy conditions along the Cascades on Day 3 (Sunday)
and Days 4-5 (Monday-Tuesday), where 40 percent critical
probabilities have been maintained. Monsoonal moisture will continue
to linger around the Four Corners region into next week, providing a
mix of wet and dry thunderstorms nearly every day into next week.
Given that storms may be on the wetter side, and may occur over the
same regions (hence the dampening of fuels), no dry thunderstorm
probabilities were added to this region. Isolated dry thunderstorms
may become an increasing concern across portions of the Pacific
Northwest into the northern Great Basin/Central Rockies region
through parts of next week as mid-level troughs traverse the
Interior West. However, given the overall weak forcing with these
low-amplitude troughs, and differences in timing of the troughs in
medium-range guidance, confidence is too low to specify the location
and timing of dry thunderstorms at this time.
