through Tuesday.

Breezy conditions can expected during the afternoon hours today and
and Tuesday as south-southwest winds generally 15-25 mph develop in
response to a couple shortwaves moving across the northwest states
and brushing the Great Basin. Temperatures will climb 4-5 degrees
today and another 3-4 degrees Tuesday leading to highs several
degrees above normal with readings across the desert zones in the
upper 80s to lower 90s by Tuesday afternoon.

.LONG TERM...Wednesday through Sunday.

Little has changed in ensemble simulations showing a sharper trough
moving through the Great Basin Wednesday into Thursday. Most
impactful weather will come in the form of stronger north winds
behind the cold frontal passage. ECMWF EFI for Tuesday night through
Wednesday suggests wind speeds for parts of northern Inyo, Esmeralda
and central Nye Counties may be unusually strong when compared
compared to model climate. However, based on latest forecast it does
not look like a wind product would be needed. On Thursday, strongest
northerly winds will be concentrated into the lower CRV. For Lake
Mohave, NBM has a 31% chance of sustained winds of greater than 25
mph. Other than Wednesday and Thursday`s brief cooldown,
temperatures will rebound to 5 to 8 degrees above normal Friday and
Saturday. South to southwest breezes expected to increase over the
weekend, however there remains quite a bit of uncertainty Sunday and
beyond in evolution of the next trough.
