...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF NORTHERN IDAHO AND INTO/ACROSS PARTS OF WESTERN MONTANA...

...SUMMARY...
Isolated thunderstorms capable of a few localized severe gusts are
possible on Friday over parts of the northern Rockies.

...Synopsis...
Upper troughing/cyclonic flow will shift very gradually eastward
across the eastern U.S. Friday, while a low off the Pacific
Northwest Coast shifts northeastward toward -- and eventually
reaches -- the Vancouver Island vicinity.  Meanwhile, persistent
ridging will persist over the Rockies and Plains.

At the surface, a cold front stretching from the Carolinas to
southern Texas will drift slowly southward across the Southeast, but
stall -- and eventually drift back north -- over southern Texas. 
Meanwhile, a weaker baroclinic zone will remain oriented roughly
north-south across the Pacific Northwest through the period.

...Northern Idaho and across parts of western Montana...
As a short-wave trough shifts northeastward toward Vancouver
Island/southwestern British Columbia, and the downstream airmass
across the interior Pacific Northwest heats/destabilizes diurnally,
afternoon thunderstorm development is again expected across the
region.

With moderate destabilization (mixed-layer CAPE generally around
1000 J/kg) expected, and moderate westerlies aloft, a couple of the
stronger storms may organize, bringing attendant risk for a damaging
gust or two into the evening hours.  While gradual stabilization
through the evening would otherwise suggest a decrease in severe
potential, a few CAMs suggest that some upscale growth of convection
may occur, spreading eastward toward central portions of Montana. 
With a modest (15 to 25 kt) east-southeasterly low-level jet likely
to develop, this seems plausible, though risk for damaging winds may
remain mitigated by the gradually stabilizing boundary layer. 
Still, an eastward expansion of the MRGL/5% wind risk area is being
included at this time.
