Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1038 AM CDT Sat Aug 10 2024

Valid 101700Z - 111200Z

The previous forecast remains on track with only minor adjustments
needed. Elevated fire weather conditions remain likely across
northern NV into adjacent portions of northwest UT and southern ID.
Isolated thunderstorms are ongoing across parts of central ID as of
15 UTC. The dry boundary layer sampled by the 12 UTC BOI sounding
should promote the potential for dry thunderstorms, though recent
MRMS rain rate estimates and sparse rainfall measurements suggest a
mixture of dry and wet thunderstorms is most likely ongoing, which
should continue into the afternoon. Given a handful of fire reports
and sporadic wetting rainfall over the past 24 hours, fuels should
generally remain receptive to new dry-lightning fire starts.

.PREV DISCUSSION... /ISSUED 1252 AM CDT Sat Aug 10 2024/

...Synopsis...
Today, a mid-level trough in the Northwest will slowly drift east
and lose amplitude through the day. A belt of stronger mid-level
winds will exist from northern California into parts of the northern
Rockies. A modest surface trough will develop in the northern Great
Basin.

Elevated fire weather conditions are probable along/ahead of the
surface trough/weak boundary in the northern Great Basin. Winds of
15-20 mph will be co*mon along with 10-20% RH during the afternoon.

Isolated dry thunderstorms appear most likely to occur in parts of
central/southern Idaho. Here, storm motions will be faster given the
mid-level jet position overhead. While thunderstorms are certainly
possible in parts of the Northwest, slower storm motions due to much
weaker flow aloft will increase the potential for wetting rainfall
to occur.
