Day 2 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1258 PM CDT Mon Jun 27 2022

Valid 281200Z - 291200Z

...Dry Thunder...
As drier air begins to work in ahead of the Pacific trough, dry
thunder probabilities will shift eastward slightly along with the
edge of the monsoonal moisture plume. The best chances for dry
storms appears to be across central UT and far northwest CO. While
fuels are likely patchy owing to several days of scattered storms,
the coverage of lightning should support an isolated risk for
ignitions despite somewhat marginal conditions. The IsoDryT area has
been adjusted slightly to the latest guidance.

...Snake River Plain...
Strong mid-level flow associated with the advancing trough is
forecast to overspread southern ID and northern portions of the
Great Basin through Tuesday afternoon. While fuels are currently
limited due to green up, the potential for surface gusts of 25-30
mph and humidity of 20-25% may still support a localized risk for
elevated fire weather conditions through the afternoon hours. See
the prior outlook for additional information.

.PREV DISCUSSION... /ISSUED 0208 AM CDT Mon Jun 27 2022/

...Synopsis...
Slight flattening of the upper ridge across the West is expected as
a mid-level trough overspreads the Pacific Northwest and approaches
the northern Rockies tomorrow/Tuesday. Strong upper support in
association with the mid-level trough will promote Elevated to
locally Critical surface winds/RH to the lee of the southern
Cascades/northern Sierra during the afternoon hours. By afternoon
peak heating, isolated to potentially scattered high-based
thunderstorms will likely develop across eastern parts of the Great
Basin. While the storms should be slow moving and potentially wet, a
few lightning strikes may occur away from precipitation cores into
potentially critically dry fuel beds, necessitating the introduction
of isolated dry thunderstorm highlights.
