NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Boise Idaho 
830 PM MDT Friday Jul 3 2015 

Discussion...thunderstorms along the Nevada border reached maximum 
development and northward extent around 00z but have already dissipated. 
No other storms expected tonight. Another hot day on the Fourth of 
July but a little cooler Sunday as an upper trough passes by in western 
Canada. No updates. 


Aviation...VFR. Scattered-broken middle level and high clouds through Saturday 
morning. Surface winds...mainly northwest 10-15 kts decreasing to 
less than 10 kts by 06z. Winds aloft...northwest 10-20 kts up 
through 10k feet mean sea level. 

Weekend outlook...isolated afternoon and evening thunderstorms...on 
Saturday south of the Snake River Valley in Idaho and the southern 
halves of Harney and Malheur counties in Oregon...spreading north 
over Idaho on Sunday to the Snake River Valley east of kboi...and 
the Boise and west central Idaho mountains. 


Previous discussion... 
short term...tonight through Monday...upper level ridge remains 
centered over Utah with the axis going through northern Nevada and into 
northern California. This is inhibiting moisture from moving very far north 
across the Nevada border. We have a slight chance of showers and 
storms near that border this afternoon and evening. A trough will 
move by to the north tomorrow...passing through northern Idaho and into 
Montana. This will draw moisture northward and extend the chance 
for showers and storms farther north into our County Warning Area tomorrow 
compared to this afternoon and evening. Precipitable water values at kreo go from 
approx 0.80 this morning up to around an inch tomorrow afternoon 
according to NAM forecast soundings. Sunday...the ridge axis 
slides slightly north...keeping the chance of storms restricted to 
the south and east. Temperatures will cool slightly in the wake of the 
trough that passed by to the north on Saturday. Monday will be 
nearly a Carbon copy of Sunday as the ridge axis moves very 
little. Winds will be light apart from showers and storms...where 
a significant gust threat exists owing to very dry lower levels of 
the atmosphere. 

Long term...Monday night through Friday...the upper level ridge will 
weaken a broad upper level trough along the Canadian 
border extends south into Idaho. Meanwhile...a closed upper level 
low will slowly track northeast over California - finally 
reaching eastern Oregon and southwestern Idaho by middle-day Friday. This 
pattern shift will bring some respite from recent triple digit 
temperatures...with valley highs forecast to peak in the 90s 
Wednesday through Friday. Also...improved model agreement 
regarding the movement of the closed low warrants increased 
confidence in convection. Therefore...have increased probability 
of middle-week showers and thunderstorms - especially south and west 
of the Snake River.
