NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Pocatello Idaho 
152 PM MDT Thursday Jul 30 2015 

Discussion...tonight through next Thursday. A high pressure ridge 
will continue to expand across the Great Basin through Saturday. 
Satellite imagery was showing several features rotating north along 
the western periphery of the high which will help to inject sub-tropical 
moisture into southern Idaho. The models continue to show some influx of 
this moisture as early as Saturday afternoon and to a greater extent 
starting Sunday afternoon and continuing through Thursday. In 
addition to the influx of moisture...a low pressure system is 
expected to shift slowly south along the Canadian coast Sunday 
through Thursday...gradually shunting the upper ridge axis east of 
The Divide by Monday with ill timed disturbances embedded in the SW 
flow aloft helping to trigger periodic thunderstorm activity. I have 
no illusion that the GFS model actually has the timing of these 
passing waves correct at this point but the overall pattern change 
is also reflected in the European model (ecmwf). So for now...have begun to bump the 
precipitation/thunderstorm chances upward starting Monday coincident 
with the break down of the upper ridge. Huston 

Aviation...cigs/vsbys unlimited and light wind under high pressure 
continues. Messick 

Fire weather...warming and drying continues through Sat with light 
wind under strong high pressure. The high will entrain some unstable 
air...potentially starting as early as Sun afternoon. The area 
affected would be the extreme western edge of the forecast area. On 
Monday...the thunderstorms will spread across all zones for the 
afternoon...with the moisture content...known as precipitable 
water...indicating dry mixed with wet as most likely. This is 
especially true after the extended dry period. The main forecast 
problem until then is the extreme dryness at 10000 feet and the 
unstable air which is pushing the Haines index to 6 in widespread 
areas. Fortunately wind is light even with the higher altitude winds 
reaching down to the surface. The highlight for the extended is the 
thunderstorm activity...potentially dry...for many areas that have 
had strong curing these past seven to nine days. Messick 

Pih watches/warnings/advisories...none.
