...Heat to extend through July 4th...

.DISCUSSION...A few showers and thunderstorms are possible
through Glacier National Park today as a shortwave passes out of
Canada. The rest of the region can expect continued very warm and
dry conditions today.

High pressure over the Western United States will keep very warm
temperatures through the rest of this week and during the 4th of
July. A few weak shortwaves will pass in the coming days so
temperatures are not expected to be as hot as last weekend.
Afternoon breezes are also expected each afternoon.

The ridge over the region is forecast to flatten on July 4th as a
trough approaches Idaho and Montana. Increased wind can be
expected on Saturday with wind gusts of 25-30 mph possible. This
wind, along with the recent heat, and lack of precipitation brings
increased fire concerns Saturday.

Extended model guidance have agreement that a trough will pass on
Sunday. There will be an increase in shower chances with the
trough. Though, these appear to mainly be along the divide at
this time.


.AVIATION...Thunderstorms are passing north of the US/Canadian
border this morning in association with a passing shortwave. Once
this shortwave moves in the Glacier Park Region showers and
thunderstorms will be possible this afternoon and evening. The
rest of the region will continue to have very warm temperatures,
dry conditions, and increased afternoon winds.
