Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0222 PM CDT Sun Jun 30 2024

Valid 011200Z - 021200Z

...20z Update...
Minor changes have been made to adjust the Elevated area to better
match greater fire-weather potential across portions of the northern
and eastern Great Basin. Dry and breezy conditions are possible over
a broad area within a post-frontal flow regime across NV. At least a
few hours of 10-20% RH are likely to overlap with northwesterly
gusts of 15-20 mph. The most likely corridors for sustained elevated
to near-critical fire-weather conditions will be across portions of
southern ID and eastern NV into southwest UT. Localized fire-weather
conditions are also possible in northern CA. See the prior
discussion.

.PREV DISCUSSION... /ISSUED 0204 AM CDT Sun Jun 30 2024/

...Synopsis...
A mid-level trough will continue to progress eastward and impinge on
the Rockies tomorrow (Monday) while upper ridging prevails across
the central U.S. A mid-level jet streak will pivot around the trough
and overspread the Great Basin region, supporting another day of dry
and breezy conditions. By afternoon peak heating, much of the Great
Basin will experience 15+ mph sustained west-southwesterly surface
winds amid 10-15 percent RH, warranting the introduction of Elevated
highlights. Dry conditions (i.e. RH as low as 10 percent in spots)
are also expected across much of the California Central Valley
region, where fuels are becoming increasingly receptive to wildfire
spread. At the moment, the consensus among model guidance members
suggests that surface winds will be on the lighter side, with fire
weather highlights withheld for now. However, at least Elevated
highlights may be needed in future outlooks if guidance trends
windier in California.
