Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0148 PM CDT Tue Aug 09 2022

Valid 101200Z - 111200Z

The forecast generally remains on track. The isolated
dry-thunderstorm risk area is expanded into parts of northern WA
where forecast soundings show LCLs between 2-2.5 km coincident with
fast storm motions (near 20-30 knots), a QPF minima over the next 48
hours, and dry fuels based on latest fuel guidance. Elevated wind/RH
conditions remain likely across northeast CA into OR as well as
across northeast MT. Drier model solutions hint at the potential for
periods of critical conditions in the lee of the Cascades (with RH
in the teens and winds between 20-25 mph), but this potential
appears too localized to warrant an upgrade at this time. See the
previous discussion below for additional details.

.PREV DISCUSSION... /ISSUED 0158 AM CDT Tue Aug 09 2022/

...Synopsis...
An upper ridge will remain in place across the Inter-mountain West
as a 500 mb closed low rides up the Pacific Northwest coastline
tomorrow/Wednesday. Strong mid-level winds overspreading and mixing
down the lee of the Cascades will promote Elevated conditions across
eastern Oregon and surrounding areas during the afternoon hours. It
is possible these highlights may need to be removed in later
outlooks if Day 1 storms produce widespread wetting rains over this
region. Modest mid-level flow pivoting around the upper ridge will
overspread a deep, relatively dry boundary layer across the northern
Rockies, with Elevated conditions expected tomorrow afternoon across
northern Montana. At least locally elevated conditions are expected
farther south to the Wyoming/Nebraska border, with an overall weaker
surface wind field precluding Elevated highlights this outlook.

As the axis of deeper monsoonal moisture shifts eastward tomorrow,
away from the Cascades, scattered to potentially numerous
thunderstorms are possible across parts of the northern Rockies.
Isolated dry thunderstorm highlights were added to portions of
northern Idaho and surrounding areas, where observations suggest
fuels are highly receptive to wildfire spread. As on Day 1, the dry
thunderstorm highlights were added because of the potential for
peripheral dry strikes (away from cores) and gusty erratic winds to
occur in these highly receptive fuel beds.
