   ...Synopsis...
   Between a midlevel trough moving across BC and an expansive
   large-scale ridge over the central/western CONUS, enhanced
   deep-layer south-southwesterly flow will overspread a deep/dry
   boundary layer (around 10-15 percent RH) in the lee of the northern
   Sierra and Cascades. These dry conditions combined with around 15
   mph sustained west-southwesterly surface winds will favor elevated
   fire-weather conditions during the afternoon, given dry/receptive
   fuels.

   ...Discussion...
   A shortwave trough will move across British Columbia/Alberta on Day
   3/Saturday, encouraging a dry airmass to translate northeastward
   into the Pacific Northwest and Northern Rockies through the weekend.
   Through the remainder of the forecast period, guidance indicates an
   upper ridge (currently atop the northern Plains) will gradually
   shift westward to encompass much of the western CONUS, while the
   eastern US is expected to remain in a progressively active troughing
   pattern. Daily chances of thunderstorm activity are possible across
   the eastern CONUS with several embedded shortwaves within the larger
   troughing pattern, and across the Intermountain West as monsoonal
   moisture advects northward once again. Portions of the Northwest,
   Pacific Coast, and central/northern High Plains are forecast to
   remain hot and mostly dry within the overall pattern, possibly
   leading to increasing fuel receptivity. 

   Strong south-southwesterly flow aloft behind an exiting shortwave
   trough will encourage dry and windy conditions across northeastern
   California, northwestern Nevada, and central Oregon/Washington on
   Day 3/Saturday. With preceding days of thunderstorms and numerous
   lightning ignitions across the region, 15-25% RH values and locally
   gusty winds could permit additional lightning holdovers to emerge.
   Meteorological conditions may further intensify the increasingly dry
   fuelscape, potentially impacting new/ongoing wildfires and control
   efforts. 40% Critical probabilities have been introduced to account
   for this threat.
