high pressure will build into north central Idaho and western
Montana today, so above average temperatures will continue.
Glacier National Park may see a few showers and thunderstorms,
otherwise, the rest of the region looks to be dry with afternoon
High temperatures on Saturday are still on track to be some of
the warmest that we've seen all month, which lines up with the
climatologic warmest day of the Summer, meaning average
temperatures begin to cool on Sunday.
Temperatures will be cooler on Sunday and winds will become gusty
by the afternoon with a cold front passage. The airmass behind
the cold front is forecast to be very dry, so there will likely
be little if any storm activity. The dryness and winds are the
main concern with increased fire threats and choppy water on area
Weak high pressure on Monday will again push temperatures above
normal with afternoon breezes.
Model guidance now agree that yet another, potentially stronger,
cold front will pass on Tuesday. This cold front has the potential
to knock high temperatures back into the 70s while also producing
gusty winds and another day with increased fire threats.
The rest of next week looks to be dry with slightly below normal
Aviation...high pressure is building into north central Idaho and
western Montana this morning and is expected to bring warm and
dry conditions. High based cumulus clouds will build during the
afternoon, but Glacier np is one of the only areas with a chance
to see a couple of storms this afternoon.
