.DISCUSSION...Another day of high pressure has produced lovely
conditions across the Northern Rockies, and will keep this string
of pleasant, summer-like weather going through at least mid-week.
Temperatures each day are still expected to warm up to 5 degrees
per day, topping out around the upper 70s to upper 80s by Tuesday
and Wednesday. Plenty of sunshine will be present, as well as
generally light winds and cool nights.

This will start to change by midweek as well, as a trough of low
pressure makes landfall on the Pacific coast Wednesday. This will
allow the Northern Rockies to transition to warm and unstable
southwesterly flow. An influx of moisture will allow for the
chance of thunderstorms Wednesday and Thursday as the trough moves
closer to the Continental Divide. By the end of the week, we will
have made a full transition back to autumn-like conditions:
cool, breezy, and rainy.

The forecast models try to bring another area of high pressure
back in over the weekend, so will keep an eye on this to see how
long precipitation and unsettled weather ends up lingering.

.AVIATION...Optimal flying conditions are anticipated across the
region for the next several days.
