Area forecast discussion 
National Weather Service Elko Nevada 
349 am PDT sun Mar 21 2010 


Synopsis...high pressure will bring one more mild day to the 
Silver state today. A cold front moving through the state tonight 
and Monday will bring isolated showers north...and cooler daytime 
temperatures Monday and Tuesday. High pressure will build back 
into the region midweek... bringing a return to warmer 
temperatures. 


&& 


Short term...today through Tuesday. At 500mb high pressure will 
shift east today as a trough moves onto the northern California 
coast. The trough...and associated cold front...will move across the 
north tonight...bringing the 700mb temperature down to -7c as far south 
as Elko. A stronger cold front will kick through the area Monday 
night...bringing the 700mb temperature down to -10c over Elko by Tuesday 
morning. Precipitable waters will be low with both fronts...around 0.35 
inches...so marginal lifted indice's will have little affect. Measurable 
precipitation will be mainly north of eko and wmc Monday...except 
extending south into White Pine County. Trace precipitation...either 
sprinkles or flurries... will be possible in wmc and eko. Showers 
will linger Monday evening across White Pine County. Isolated 
snowfall totals of up to an inch can not be ruled out in White 
Pine County above 6500 feet. 


High pressure will begin building back into the area on 
Tuesday... with a brisk north wind keeping afternoon temperatures on the 
cool side. Rea 


Long term...Tuesday night through Saturday. Not much was changed 
in the long term for this package from what was already in the 
forecast as the 0z GFS and ec are fairly similar to previous runs. 
Ridge still expected to build in Tuesday night and Wednesday. Weak 
system still expected to pass to the north Thursday. Stronger but 
still rather dry system still possible on Friday before another 
ridge moves back in Saturday. Temperatures still expected to be 
near to above normal thanks to zonal flow off the mild Pacific.

Aviation...VFR conditions expected through the taf period. High 
clouds through 0z will then begin to lower and thicken at keko and 
kwmc...but should remain fairly high and thin at kely and ktph. 
However...ceilings should remain above VFR thresholds. A few showers 
may pass fairly close by to the north of kwmc and keko after 
2z...but none are expected to directly affect either terminal. 
Winds will generally be light...but can gust over 20 knots between 
20z and 2z...particularly at kwmc. Rcm
