Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1108 AM CDT Sun Jul 24 2022

Valid 241700Z - 251200Z

The previous forecast (see below) remains on track, with only minor
changes made to the fire weather highlights to reflect the latest
guidance consensus.

..Squitieri.. 07/24/2022

.PREV DISCUSSION... /ISSUED 0156 AM CDT Sun Jul 24 2022/

...Synopsis...
A co*pact midlevel shortwave trough will track eastward from the
Northern Great Basin into the northern Rockies today. Within the
base of the trough, deep/enhanced westerly flow will overspread
parts of southern ID into western WY -- where single-digit to lower
teens RH will develop during the afternoon. The co*bination of 15-20
mph sustained westerly surface winds, critically low RH, and
receptive fuels will result in elevated to spotty critical
fire-weather conditions this afternoon.

In addition, increasing large-scale ascent ahead of the shortwave
trough will encourage widely scattered, high-based thunderstorms
over eastern ID into western MT. As these storms overspread a
hot/deeply-mixed boundary layer and receptive fuels, isolated
lightning-induced ignitions will be possible away from any
precipitation cores.

Farther south over the southern Plains, breezy southerly surface
winds near 15 mph will develop in response to a weak surface low
near northwest OK. The breezy surface winds, coupled with 20-25
percent minimum RH could lead to locally elevated conditions from
the TX/OK Panhandles into western OK. However, these conditions
appear too marginal/localized for Elevated highlights.
