...Central Nevada...
Increasing mid-level flow on the southeastern periphery of a cut off
low off the northern CA coast will overspread portions of the Great
Basin today. A very dry boundary layer with single digit relative
humidity and sustained south/southwest winds of around 15 mph will
support elevated fire weather conditions over portions of central
Nevada this afternoon. Otherwise, previous forecast (see below) for
isolated dry thunderstorms across far northern CA into south-central
OR remains consistent with latest short term model guidance.

...Synopsis...
A midlevel low off the northern/central CA coast will move slowly
northward through the period. Related midlevel ascent will
overspread northern CA into southern OR, aiding in the development
of isolated high-based thunderstorms over the higher terrain during
the afternoon. Deep inverted-V soundings with 0.5-0.75 inch PW will
favor dry thunderstorms, with an associated risk of
lightning-induced ignitions and gusty outflow winds atop receptive
fuels.
Farther south, enhanced southerly flow peripheral to the midlevel
low will overspread a well-mixed boundary layer across the Great
Basin. This will promote locally dry/breezy conditions, with locally
elevated fire-weather conditions possible over parts of
central/southern NV during the afternoon.
