Valid 241200Z - 251200Z

...Synopsis...
Embedded within a belt of enhanced southwesterly flow aloft, a
subtle/low-amplitude wave will overspread parts of the northern
Great Basin. Here, sufficient midlevel moisture atop a diurnally
deepening boundary layer will promote isolated high-based
thunderstorms across parts of northern NV, southeast OR, southwest
ID, and far northeast CA during the afternoon and early evening. PW
values around 0.6 inches will favor mostly dry thunderstorms, which
will pose a risk of isolated lightning-induced ignitions, given a
dry/receptive fuelscape (90th-95th percentile ERCs).

Farther south, a surface low will evolve eastward across parts of
the southern Plains during the day. A tightening pressure gradient
peripheral to this feature will aid in the development of 15-20 mph
sustained west-southwesterly surface winds across parts of the TX
South Plains into southwest OK during the afternoon. These winds,
combined with 15-20 percent RH, will lead to elevated fire-weather
conditions.
