.DISCUSSION...

Weak ridging continues over the region for the next few days.
This will lead to daytime highs in the upper 60s-70s for Sierra
communities and upper 70s to mid-80s for western Nevada valleys
throughout the week. The warm temperatures across the area will
result in additional snowmelt of the Sierra snowpack leading to
fast and cold streamflows. However, we are not expecting any
flooding impacts at the moment.

A couple of weak shortwave troughs will clip the area to our
north during the second half of the week. The main hazard with
these systems will be gusty winds and slight chances of
rain/thunderstorms over far NE CA and NW NV. Most of the area has
a 30-60% chance of observing winds greater than 40 mph both on
Thursday and Friday. Wind prone areas have a 10-20% chance of
exceeding 55 mph. Winds will also result in choppy lakes,
including Pyramid Lake and Lake Tahoe. These winds, combined with
low relative humidity (10-20% W NV, and below 7000 ft of Mono,
Alpine and Lassen; 20-30% Sierra and above 7000 ft Lassen, Mono
and Alpine) areawide will lead to an elevated fire weather risk
for western NV. There is also a 10-25% chance of rain over far
northern Lassen, the Surprise Valley, and far north Washoe near
the OR border, along with a 10-15% chance for storms on Friday.

The Memorial Day Weekend is continuing to trend warm and dry as
another high pressure moves into the Great Basin. Therefore, the
aforementioned information about temperatures and streams is still
valid. There is a 10-15% chance for showers and thunderstormson
Sunday and Monday again over far NE CA and NW NV, and less than 5%
over the Sierra. Although, there is still plenty of uncertainty
per NBM guidance, and multiple ensemble members of the global
models.
