.DISCUSSION...
Issued at 213 AM MDT Sun May 3 2026

Little changes in the forecast as a whole. Outside chance for
showers today, mainly over the central mountains as the ridge
over our area breaks down and a low pressure system approaching
the California coast begins to interact with a bigger trough
positioned to our northeast. Better chances for scattered
showers and thunderstorms exists Monday into Tuesday as the low
moves through the southwestern U.S. We`re not expecting much
precipitation from this system, although some local areas could
pick up a quick 0.25" inches from a thunderstorm. Winds begin to
pick up from the northeast on Tuesday with that system to our
south. Looks like winds will be strong enough for a lake wind
advisory on the American Falls Reservoir with strong chop likely
near the dam. Colder air works into the region on those
northerly winds, and it looks like we could be in store for
another round of frost/freeze for Wednesday morning. Temps look
more reasonable than what we dealt with reasonably, lower 30s
across the Snake Plain. The ridge builds back in for Wednesday
and beyond with dry weather likely for the latter half of the
week. There`s an outside chance for some rain next weekend as a
weak system passes to our north. Temperatures rebound with some
areas flirting with 80 degrees by the end of next week.

We are looking at more VFR weather, although we should see an
increase in afternoon cloud buildup today and tomorrow. For
today, it is very dry below the cloud layer and this would
indicate virga and quick burst of wind vs actual moisture (other
than sprinkles) falling. Even if we do get a shower or storm to
impact a particular airport, it would be around 10% or less, and
would most likely be at SUN or DIJ.
