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. && $$
