   ...Days 3-5/Monday-Wednesday...
   A mid-level trough descending southeastward from British Columbia
   will bring increasing fire weather concerns to portions of the
   Northwestern U.S. and Great Basin early next week. Accelerating
   winds ahead a strong cold front, low daytime relative humidity and
   dry fuels will increase wildfire spread potential across the
   Columbia Basin and Snake River Plain on Day 3/Monday, with overall
   fire weather threat shifting into the Great Basin by Day 4/Tuesday.
   The resulting back door cold front and north-northeast pressure
   gradient could also bring a period of weak offshore flow to the
   coastal ranges of OR Day 4-5/Tuesday-Wednesday, but some lingering
   model uncertainty in wind magnitude precludes introduction of
   critical probabilities at this time. Farther east, wetting rains and
   cooler temperatures associated with the trough and cold front should
   mitigate fire weather concerns across much of Montana Day 4/Tuesday.


   ...Day 6-8/Thursday-Saturday...
   A mid-level low near Baja California along with a general rebuilding
   of the ridge across the Western U.S. could aid in ushering in deeper
   monsoon moisture into portions of the Southwest and Great Basin for
   the latter portion of the week. Considerable ensemble spread in
   moisture plume evolution limits confidence in isolating dry
   thunderstorm threat for now.
