.DISCUSSION...

Through Tuesday night...

Canadian trof dropping southeast through Montana on the way into
the northern plains will bring isolated showers and thunderstorms
to mainly the eastern half of the forecast area through this
afternoon. Best chances for precipitation will be counties along
the eastern state line. Otherwise expect a good deal of sun today
with season temperatures in the lower to middle 80s and a light
easterly breeze.

Ridging builds over the area for Tuesday for hot and dry
conditions. Expect highs well into the 90s for most locations,
with a few triple digits not out of the question. Those with
outdoor plans and especially those that work outdoors should be
prepared for the heat and take precautions to prevent heat related
illness. Chambers

Wednesday through Monday...

Heat continues Wednesday with upper level ridging over the area.
An approaching Pacific system will add some compressional warming
to the mix boosting highs a few degrees over Tuesdays expected
readings. Looking at a lot of upper 90s to over 100 degrees being
advertised, with the hottest temperatures along the Yellowstone
river from Billings to Miles City as well as across the Crow and
Northern Cheyenne reservations. Current Heat Risk forecast is
suggesting the need for a Heat Advisory for Wednesday from
Yellowstone county east to Custer county. Will keep an eye on this
and make a decision over the next couple of shifts. Once again,
if you have outdoor activities planned, or work outdoors, be sure
to take precautions to prevent heat illness during this period of
heat.

Aforementioned cold front looks to arrive a bit faster than
previously forecast with winds turning northwesterly by sunrise
Thursday. Forecast highs for Thursday are looking 10 to 15 degrees
cooler than Wednesday with mainly mid 80s across the forecast
area. Precipitation chances hold off until Thursday afternoon, but
by Thursday evening 30 to 50 percent chances are widespread across
the area.

Precipitation looks to end Friday morning with a very pleasant
afternoon on tap. Friday afternoon temperatures are forecast to be
mainly in the upper 70s despite plenty of sun, along with a light
northerly breeze. Looks like a great day to get outdoors,
especially the mountain foothills that may stay in the 60s for
afternoon highs.

Hotter temperatures returns for next weekend, though there is
increasing uncertainty regarding how warm during this period. The
most recent models are starting to hint at a frontal boundary
dropping in Saturday afternoon with northerly low level winds
persisting through Sunday. NBM spreads for Max Temperatures for
the weekend have widened due to this. So, take next weekend/early
next week specifics with a grain of salt as we see how the models
evolve with this potentially cooler and more unsettled pattern
thats emerging. Chambers
