.KEY MESSAGES...

- Daily record high temperatures possible tomorrow.

- Weak dry cold fronts Wednesday night and Saturday.

- Warmer and drier than normal for the foreseeable future.

&&

.UPDATE...
Strong high pressure aloft continues to dominate our weather.
There was some diurnal cumulus (w/ perhaps isolated sprinkles)
over south central MT but this is staying to our west and
dissipating as we approach sunset. The Elk Fire is also beginning
to cool per IR imagery. Quiet weather in store tonight w/ low
temps in the 40s to mid 50s. Backing mid level winds tomorrow may
help push at least some of the ID smoke to our north, so although
smoke from the Elk Fire will continue to be an issue, it is
possible that skies over our west will turn a little less hazy on
Wednesday. JKL

.DISCUSSION...
Through Wednesday night...

Upper level ridging will become more amplified today, due to a
deepening Pacific trough. As a result, stronger southwest flow
will befall the region. Temperatures are currently in the upper
60s to 70s, expect temperatures to top out in the 70s to low 80s.
Stronger WSW flow on Wednesday will result in warmer high
temperatures, with highs in the 80s. Several locations including
Billings, Baker, Livingston, and Sheridan, have the chance to
break their daily record temperature tomorrow, The probability
for a temperature of 85F or greater is 40-75%, from Billings east,
highest in the river valleys and around Sheridan.

A dry cold front arrives Wednesday night shifting winds to the
north. No precipitation is expected through the short-term
forecast period.

Thursday through Tuesday...

To be honest, there`s very little to discuss for this period. End
of the week into early next week is dominated by upper ridging
over the area and mostly northwest to northerly flow aloft coming
over the area. This pattern will continue to bring about above
normal temperatures and mostly dry conditions. The only slight
change to this is expected to come from a deep upper low cutting
south over the eastern part of the CONUS, and reaching slightly
into far eastern MT. This cyclonic flow would briefly bring about
slightly cooler temperatures and a small chance for light rain.

For this brief cooldown over the weekend, both Saturday and Sunday
night has a 25% chance of low temperatures dropping below 32F,
with far eastern MT increasing to 50%. Vertz

.AVIATION...

VFR conditions will prevail for the next 24 hours. Wildfire smoke
will reduce slant range visibility at times across the area. Will
keep an eye on wildfire smoke as amendments may be needed with
increased concentrations.
