.DISCUSSION...Afternoon and evening showers will be common across
most of western Montana and north central Idaho through sunset
tonight. Then, after skies clear through the night, the region
will be waking up to a very pleasant spring day for your Saturday!
Temperatures will warm into the 50s for western Montana, and into
the low 60s across areas of central Idaho (namely, the Camas
Prairie region). Skies will be mostly sunny, and aside from an
afternoon breeze, the day will be a much-needed break from all the
dull and dreary weather as of late.

That being said, another wet system will enter from the west late
on Sunday, but will be rather quick to exit the region on Monday.
This system could produce some isolated thundershowers,
particularly on Monday afternoon, with mountain snowfall in
terrain above 6000 feet. Average high temperatures for this first
week of May will climb into the mid 60s by the middle of the

Another weather disturbance will bring showers and below normal
temperatures to the area late Monday and Tuesday. The system will
exit the region Tuesday evening as a strong high pressure ridge
noses its way into the region. Confidence is pretty high for the
development of this ridge, which will bring dry weather, a good
amount sunshine, and temperatures to above normal Wednesday and
Thursday. Temps in the mid to upper 60s are likely Wednesday. And,
believe it or not, hold your hats, high temperatures next Thursday
are expected to be in the upper 60 to lower 70s (perhaps even
warmer). Temps in the 70s Thursday will break our streak of
almost 7 months without a high temperature in the 70s; one of the
longer streaks we have on record.

A cold front is anticipated to cool things off again Friday or
Saturday, with breezy conditions Friday and a potential for
showers and perhaps a thunderstorm.


.AVIATION...Showers are developing across the breadth of the
Northern Rockies this afternoon, and should produce periodic
bursts of rain for all terminals through 29/0300Z. Afterward,
expect skies to clear overnight, with a very pleasant, fair-flying
day expected for Saturday. Winds will be light and variable during
this time, aside from a diurnally-driven breeze across the region
after 29/2200Z.
