...Heightened Fire Weather Concerns For Southwest Montana Saturday...

.DISCUSSION...

Idaho: Warm and dry conditions continue through Sunday, with diurnal
winds. Today will be the driest day of the weekend, with a slight
moistening as flow aloft shifts from westerly to northwesterly Saturday.
On Sunday, a wave will slide out of Canada mostly affecting western
Montana, however, the northeast corner of the Clearwater Mountains may
see a shower or two. Next week the flow changes back to westerly, with
warming and drying until Wednesday when isolated thunderstorms are
possible.


Montana: Warm and very dry in southwest Montana today, with heightened
fire weather concerns both today and tomorrow. Over the weekend, the
flow changes to northwesterly with a slight moistening of dew points.
Additionally, a wave slides out of Canada bringing gusty northwest
winds. Gusts to 30 mph are possible in southwest Montana not quite
attaining warning criteria but heightened concerns are warranted. On
Sunday, a few showers or thunderstorms are possible mainly east of
US-93. The best chance of a wetting rain is best for the Mission and
Seeley Ranges, along with Glacier National Park. Next week warming and
drying returns through Wednesday. The possibility exists for isolated
thunderstorms Tuesday through Thursday in west- central and southwest
Montana.
