.DISCUSSION...
Issued at 1200 PM MDT Mon Jun 1 2026

Low pressure will finally shift out of Montana in the next 24
hours, bringing a brief respite from showers and thunderstorms
tomorrow and a good chunk of Wednesday. The best chance of rain
producing storms through this evening will be across the central
mountains and along the Montana border. Farther south and along
any outflow from storms, we may see isolated virga "showers" and
perhaps a few thunderstorms. There is a 10-30% chance of gusts
35-45 mph today, with a very small chance of gusts over 50 mph
with anything move out over the Snake Plain. Even though we are
not looking at any rain or thunder between lows, it does look
like we should see some afternoon clouds especially over the
mountains and given the time of year, the potential for virga.
It looks like the next storm for Wednesday-Thursday is far
enough north, that any potential for showers and storms is along
the Montana border, and just dry and breezy outside of that. The
pattern for the weekend and into next week is a bit more
muddled. It does look like the low moving in for the weekend
will split, but it is the usual idea of how strong the split
will be and what is left to influence our weather. It is around
a 55/45 split (pun intended) between this occurring across our
area and the main low dropping south of us, or taking place out
in the Pacific. The first scenario would keep us cooler and a
higher potential of showers and storms with tapping into some
moisture. The second will give us a quick shot of moisture over
the weekend, with the northern part of the split racing by into
southern Canada. The Blend of Models currently favors more of
the first scenario. Even then, the "coolest" day (Sunday) would
still be right around AVERAGE temperature-wise. Speaking of
temperatures, highs quickly bounce back into the 70s and 80s for
the next 7 days. The "warmest" days should be Wednesday, Friday,
and Saturday, where warmer spots will push toward the mid to
upper 80s.
