Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1113 AM CDT Sun Aug 11 2024

Valid 111700Z - 121200Z

...NO CRITICAL AREAS...

A pair of isolated dry-thunderstorm risk areas have been introduced
for this morning`s forecast update. 12 UTC soundings from BOI and
OTX sampled relatively dry low-level conditions and PWAT values
similar to previous days that have seen a mixture of wet and dry
thunderstorms. MRMS rainfall estimates and surface observations
suggest that most locations have not received wetting rainfall over
the past 48 hours with several lightning-caused fire starts have
been reported during this period. Morning HREF guidance shows a
signal for isolated convection this afternoon and early Tuesday
morning with favorable thermodynamic profiles in place for a mixture
of wet/dry thunderstorms. Given recent observations, the model
signals, and antecedent fuel conditions, risk highlights appear
warranted.

Localized elevated conditions remain likely across west-central NV
in the immediate lee of the northern Sierra Nevada as well as across
portions of eastern NV. However, such conditions are expected to
remain sufficiently localized to preclude highlights.

.PREV DISCUSSION... /ISSUED 1255 AM CDT Sun Aug 11 2024/

...Synopsis...
A belt of stronger mid-level winds will be present on the poleward
side of a flattened upper-level ridge in the southern U.S. With
time, a shortwave trough will amplify and move into northern
California and the northwest Great Basin. At the surface, the
pressure pattern will be rather disorganized until stronger pressure
falls occur in the Northwest late in the period.

Fire weather concerns are expected to be low for most areas today.
Some locally elevated conditions are possible in parts of
central/northern Nevada. RH will likely be in the 10-15% range, but
winds will be light. The potential for thunderstorms over
sufficiently dry fuels is also too low for highlights.
