   As a strong deep-layer cyclone approaches the British Columbia
   coast, a series of lower-amplitude troughs to the south and east of
   the cyclone is expected to move into the Northwest and northern
   Rockies. At the surface, a cold front will move across portions of
   the northern Rockies and the northern High Plains as a surface low
   approaches Hudson Bay. Portions of California and the Great Basin
   will remain hot and dry. 

   ...Interior Northwest into the Northern Rockies -- Dry Thunderstorm
   As a low-amplitude trough approaches the Pacific Northwest, isolated
   to widely scattered thunderstorms are expected from portions of the
   interior Northwest into the Northern Rockies. At this time, as with
   the previous system, it appears that thermodynamic profiles will
   support a mix of wet and dry thunderstorms, with some risk of
   ignitions in areas of dry fuels. 

   ...Northern Montana -- Elevated Wind/RH Threat...
   Dry westerly flow in the wake of a frontal passage will support the
   potential for near-critical RH across portions of northern Montana.
   There is some spread in model guidance related to the strength of
   the low-level flow in this region, but given the potential for wind
   speeds in the 15-20 mph range at peak heating, an elevated fire
   weather threat appears possible.
