   ...Dry-thunderstorm potential...
   Ascent accompanying a migratory midlevel impulse is expected to
   combine with sufficient moisture and buoyancy for isolated
   thunderstorm potential over the vicinity of the northern Great Basin
   for Day-3/Sunday into Day-4/Monday. Antecedent deep, well-mixed
   boundary layers associated with hot/dry surface conditions over the
   northern extent of an antecedent, dampening midlevel ridge will be
   favorable for a dry-thunderstorm mode, amid sufficiently dry/drying

   For Day-5/Tuesday, some dry-thunderstorm potential may affect parts
   of southern MT and vicinity as the impulse continues progressing
   eastward. However, confidence in sufficient coverage of this
   activity affecting locations where potentially dry fuels could exist
   (e.g., perhaps relegated to parts of eastern MT) is presently too
   limited for dry-thunderstorm probabilities.

   ...Strong-wind/low-RH potential...
   Sufficient enhancement to the flow peripheral to the aforementioned
   impulse is expected to support some critical, wind-driven
   fire-weather risk across parts of the southwest states and central
   Great Basin vicinity for Day-4/Monday into Day-5/Tuesday. While
   40-percent areas are in effect for Day-4/Monday and Day-5/Tuesday,
   Critical areas have not been added at this time, owing to notable
   differences among model solutions and relatively modest low-level
   flow strength depicted by multiple model solutions.

   For Day-6/Wednesday through Day-8/Friday, notable differences among
   medium-range model guidance regarding the evolution of the
   large-scale pattern yields too little predictability for
   probabilistic delineations.
