NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Boise Idaho 
852 PM MDT Wednesday Jul 1 2015 

Discussion...isolated thunderstorms which developed in southern 
Owyhee County prompted a forecast update earlier this evening. 
Since then...the convection has diminished with just a few showers 
noted on radar near the Oregon/Nevada border. The showers are 
expected to end by late this evening. On Thursday...the northern 
edge of monsoon moisture will reside near Nevada border. It will 
be another hot day as a strong ridge of high pressure aloft 
remains over the region. Forecast will be updated to end 
thunderstorms this evening and lower probability of precipitation. 


Aviation...VFR. Scattered to broken high clouds. Surface 
winds...12 kts or less. Winds aloft...west to northwest 10-20 kts 
up through 10k feet mean sea level. 


Previous discussion... 
short term...elongated upper level high pressure will remain over 
the Great Basin through Friday with ridge axis extending from New 
Mexico to southern Oregon. Monsoon moisture moving north through the 
calif Sierra Nevada will help form thunderstorms as far north as the 
Nevada/or border late today and this evening. Isolated thunderstorms in 
Nevada will get as far north as the Nevada/Idaho border. About the same 
Thursday and Friday afternoons/evenings. No storms expected in the 
rest of our County Warning Area through Friday. A degree or two hotter Thursday 
then little change Friday. 

Long term...Friday night through Wednesday. Models remain in good 
agreement through the extended period. Ridge of high pressure aloft 
is building to the northwest with the axis of the ridge near 140w. 
Flow aloft over the forecast area will shift from westerly to 
northwesterly then back to westerly as upper level troughs drop 
south along the Canadian West Coast and then move east along the 
Canadian border. First trough will move over the region Saturday 
afternoon/night with the next trough moving into the Pacific 
northwest Tuesday night. Even though models agree on the weather 
pattern they disagree on location and amounts of precipitation. 
Slight chance of showers and thunderstorms along the Nevada border 
Friday night and Saturday due to monsoon moisture trapped under the 
ridge. As the first upper level trough moves east of the region 
Saturday afternoon/evening chance of precipitation will also shift 
to higher terrain over most of the forecast area. By Sunday 
afternoon models differ on where precipitation will be with the GFS 
being the wettest and the European model (ecmwf) the driest. Some uncertainty as to 
location of precipitation but will keep at least slight chance probability of precipitation 
over higher terrain due to monsoon moisture trapped under the ridge 
and any moisture that may be moving through the flow associated with 
the upper level troughs. Temperatures will remain 10-15 degrees 
above normal.
