Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1149 AM CDT Mon Jul 01 2024

Valid 011700Z - 021200Z

...17z Update...
Confidence has increased that northerly downslope flow over parts of
the northern Sacramento Valley will likely exceed 15-20 mph from
late tonight into D2/Tues. Extreme heat is expected beneath a
rapidly building mid-level ridge that will allow for a strong
low-level thermal trough to develop. This will favor very dry and
breezy surface conditions, with diurnal RH likely falling below 15%.
As area fuels continue to dry, elevated to near critical
fire-weather conditions appear likely. The Elevated area was
expanded into the northern Sacramento Valley in coordination with
active Red Flag Warnings.

Otherwise, the previous forecast remains valid with minimal changes.
See the prior discussion for more information.

.PREV DISCUSSION... /ISSUED 0429 AM CDT Mon Jul 01 2024/

...Synopsis...
A mid-level trough will traverse the Interior West today,
encouraging surface low development near the Four Corners region.
The result will be dry and breezy conditions characterized by 15+
mph sustained west-southwesterly surface winds overlapping with
10-15 percent RH during the afternoon across much of the Great
Basin. Given drying fuels over much of the Basin, Elevated
highlights have been maintained. An outside chance for a dry
thunderstorm is also possible over portions of the Snake River Plain
in southern Idaho. However, modest fuel receptiveness, and low
confidence in storm coverage, preclude isolated dry thunderstorm
highlights.
