.SYNOPSIS...Strong high pressure builds across the west and brings
warmer temperatures to the region for the next several days. Snowmelt
from the higher elevations will increase and this continue the
elevated flows for small rivers and streams.


.SHORT TERM...Today through Sunday.
High pressure along the west coast this morning will expand
inland to the Great Basin this afternoon. By Sunday, the ridge
axis will be positioned over the west portion of the Great Basin.
Partial cloud cover over the Snake range this morning will clear
out by late morning as yesterday`s cold front dissipates. With
respect to temperatures, several degrees of warmer is expected
today and that will be followed by several more degrees on Sunday.

.LONG TERM...Sunday night through next Saturday.
Broad upper ridge will hold through Memorial Day providing sunny
skies and increasing warmer temperatures on Monday afternoon
as highs climb back up into the 80s at many locations. Tuesday
will be the warmest day with some of the normally hot spots
flirting with 90. High and mid level clouds will be on the
increase Tuesday afternoon and evening as the ridge axis shifts
east and an elongated, negatively tilted West Coast Pacific trough
begins to force shortwave energy and better moisture into Nevada
beginning Tuesday night into Wednesday.

The middle and later part of next week will be a period of
unsettled weather. A few showers and thunderstorms will impact
western parts of the CWA mainly along and west of a line from
Battle Mountain to Austin to Tonopah. Stronger southerly flow
ahead of the upper trough will exist Wednesday afternoon and early
evening in northern Nye, southern Eureka, and White Pine counties
where winds will likely gust over 30 mph. Sufficient moisture and
weak instability will allow isolated as well as pockets of
scattered showers and storms to develop on Thursday afternoon in
northern and central Nevada as the upper trough axis slowly pushes
through the state. The chance of isolated showers and storms will
linger across eastern Nevada Friday afternoon into Friday night a
secondary shortwave swings across the region. Look for daytime
temperatures to briefly cool closer to normal for Thursday and
Friday back down in the lower to mid 70s.


.AVIATION...Broad upper ridge of high pressure along the West
Coast will gradually shift east over the Great Basin and
Intermountain West this Memorial Day weekend. Quiet weather will
prevail across northern and central Nevada with VFR conditions
and light surface winds generally around or less than 10 kts at
all TAF sites (KWMC,KEKO,KELY,and KTPH) today into Sunday.


.HYDROLOGY...After a couple of cooler days, another warming trend
is on the way for later this weekend through early next week. All
creeks that flow out of mountainous areas should see significant
rises over the next several days.

The lower Humboldt River from Comus downstream through Winnemucca
to the Humboldt/Pershing County border will experience minor to
moderate flooding through the weekend. A Flood Warning remains in

The Jarbidge River has dropped below flood stage and the Flood
Warning has been cancelled. However, the Jarbidge is expected to
experience fluctuating levels below to near minor flood stage
over the weekend.

Lamoille Creek is expected to fluctuate around minor flood stage
through the weekend. A Flood Warning is in effect.

The Humboldt River at Battle Mountain is below flood stage and
continues to slowly recede. It is expected to remain in action
stage through at least the middle of next week.

The Bruneau River remains nearly steady, but is running high and
could reach minor flood stage over the weekend as temperatures
warm and snowmelt increases.

Wildhorse Reservoir is still above the spillway. There is no
threat for flooding at this time downstream along the Owyhee
