Area forecast discussion 
National Weather Service Elko Nevada 
207 PM PST Sat Nov 21 2009 


Synopsis...a storm system will bring breezy conditions and a few 
snow showers to to northern Nevada on Sunday. High pressure 
rebuilds over the Great Basin Monday...for dry conditions and 
above normal high temperatures through next weekend. 
&& 


Short term...tonight through Monday. A shortwave will continue to 
exit the region through the evening hours. Any isolated snow 
showers over NE Nevada will diminish by sunset. A brief break in the 
action is expected tonight...however a second shortwave will move 
across extreme northern Nevada Sunday...bringing some snow showers 
to areas mainly along and north of Interstate 80. Snow accumulations 
on Sunday look to be confined to the mountains of northern 
Nevada...with only trace amounts of precipitation possible in valley 
areas. 


Winds will be a bigger concern on Sunday as a 100+kt jet brushes 
across northern Nevada. Much of northern Nevada and portions of 
central Nevada are expected to be breezy Sunday afternoon. Higher 
resolution wrfarw model showing winds over and along the eastern 
slopes of mountains in northern Nevada becoming very windy...with 
localized gusts of 55-65 miles per hour in places like Ruby Valley and Clover 
Valley. 


Winds and precipitation over northern Nevada will diminish by midnight 
Sunday night as high pressure begins to build in from the 
southwest...kicking off off a long stretch of days with dry 
conditions and warmer-than-normal afternoon temperatures. 


Long term...Monday night through Friday. A ridge of high pressure 
will be building across the region Monday night and Tuesday...and 
will continue over the region through the latter portions of next 
week. As a result...expect relatively light winds with temperatures 
warming to above normal levels by mid-week. By the end of next 
week...models are hinting at a storm system impinging upon the 
Pacific northwest. Will continue with slight chance probability of precipitation in the 
extended during the period as model differences are still quite 
significant at this time. 
&& 


Aviation...VFR conditions are expected across much of the forecast 
period tonight...with local MVFR conditions possible across portions 
of Elko County in the early evening hours. By Sunday...another storm 
system will approach northeast Nevada from the Pacific northwest. 
The system will push across the region around the late 
morning hours. The best chance for showers will be north of a 
ku31-kp68-kely line. Snow levels will be around 4500-5500 
feet...with MVFR conditions expected in the heaviest showers. 
&& 


Lkn watches/warnings/advisories...none.
