Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0157 PM CDT Mon Sep 09 2024

Valid 101200Z - 111200Z

No changes to the ongoing forecast. There is some potential for very
isolated thunderstorms in the vicinity of the Blue Mountains in
Oregon, but confidence in initiation is quite low. Additional
thunderstorms are possible in parts of southwest Montana, but that
activity would quickly move into a higher PWAT airmass.

.PREV DISCUSSION... /ISSUED 0151 AM CDT Mon Sep 09 2024/

...Synopsis...
Broad troughing over the Northwest is forecast to gradually
intensify Tuesday as a stronger shortwave and mid-level jet approach
from the eastern Pacific. Falling heights and increasing flow aloft
will move inland, supporting the potential for strong surface winds
and low humidity over parts of the Northwest and Great Basin. 

..Great Basin...
Fire weather concerns will increase on Tuesday with the approach of
the strong trough/mid-level jet. Initially weak surface winds will
intensify over northwest and southern Nevada to 15-25 mph as flow
aloft increases. Several hours of elevated to locally critical
fire-weather conditions are likely as the stronger surface winds
develop with a dry air mass with RH values below 20%. Fuels are
driest across parts of the northern Great Basin and ID where
rainfall has been sparse. However, fuels farther south in NV and CA
remain sufficiently dry, and with stronger winds, elevated to near
critical conditions are likely.

...Cascades and Columbia Gorge...
Increasing mid-level winds will combine with a strong onshore
pressure gradient to drive 15-20 mph winds through the Gorge and the
western Columbia Basin along with RH potentially near 15%. The
duration of breezy and somewhat dry conditions may be somewhat
limited, but elevated to briefly critical fire weather may occur on
Tuesday.
