Area forecast discussion 
National Weather Service Elko Nevada 
258 am PDT Monday Oct 13 2008 


Synopsis...high pressure will build over Nevada today and will 
remain over the area through late next week. Near record cold 
temperatures this morning will moderate to near normal readings by 
midweek. && 


Short term...today through Wednesday. Unseasonably cold temperatures 
are gripping the County Warning Area at present with many locations near record 
lows. All areas...including West Wendover...have now touched 
freezing...so will keep the freeze warning going as planned. 
Otherwise...storm system continuing to move away today will allow 
plenty of sunshine to return to the region for the first time 
since the middle of last week. Cold low levels will inhibit 
warming somewhat...but mixing looks a bit better with the 
inversion a bit higher than it appeared earlier...so allowed for 
warmer high temperatures than was thinking last night. 


Westerly flow will dominate over the next several days with a few 
pieces of energy sliding across to the north. However...these 
disturbances are week and moisture starved...so I do not expect 
any precipitation with them...and even clouds will be rather hard 
to come by. Milder air moving in aloft will allow temperatures to 
continue moderating on Tuesday and Wednesday. Lows tonight will be 
noticeably milder compared to tonight /though still rather 
chilly/...with more moderation Tuesday night. Winds will be rather 
light until the inversion completely mixes out Wednesday 
afternoon when a somewhat stronger westerly wind will develop. Rcm && 


Long term...Wednesday night through next Sunday. There is 
general agreement between the medium-range models this 
morning...however subtle differences do exist that could affect 
day-to-day operations. Nothing significant in the forecast. 
Consensus of pattern is to produce a slow progressive low- 
amplitude ridge traversing Nevada real estate Wednesday night 
through Sunday. NAM is showing a weak shortwave moving through the 
eastern side of the advancing ridge Wednesday night that will just 
throw a few high clouds across the north. The axis of ridge will 
pass through the lkn County Warning Area Thursday night...then maintain a presence 
near the Utah/Colorado border through Sunday as a trough tries to develop 
off the California coast. As this trough deepens...a relatively warm dry southwest 
flow will persist over the state Friday through Sunday. This will 
will continue with dry forecast for now. Temperatures will be near 
normal daytime and nighttime throughout the period. Lw 
&& 


Aviation...clouds will continue to dissipate and move east of the 
area this morning. VFR conditions are expected through Monday. Lw 
&& 


Lkn watches/warnings/advisories... 
freeze warning until 8 am PDT Monday for nvz033.
