   Rain chances will continue to overspread the Pacific Northwest
   through the day Sunday as a weak upper-level impulse translates
   north within the mean flow regime. While this will maintain
   thunderstorm chances across the region, beneficial rainfall may help
   mitigate fuel dryness to some degree. A weak surface low is forecast
   to deepen east of the Cascades Sunday afternoon, which should
   augment surface winds across the northern Rockies and may support
   regional fire weather concerns outside of the corridor of better
   rain chances. Elsewhere across the West, weak surface pressure
   gradients and recent rainfall will limit additional fire weather

   ...Central Montana...
   Elevated wind/RH conditions are possible across parts of central MT
   Sunday afternoon. Easterly winds are forecast to increase in
   response to the deepening low over eastern OR/WA, and ensemble
   guidance shows reasonable probabilities for sustained winds near 15
   mph. Dry conditions are noted across this region with 10-hour fuel
   moisture values near 5%, and afternoon RH reductions to 15-20%
   appear likely as drier continental air filters in from Canada and
   the northern Plains. While elevated conditions are probable, the
   potential for critical wind speeds is low.
