.DISCUSSION...(This Evening Through Sunday)
Issued at 1256 PM MDT Sun May 24 2026

Upper flow is transitioning this afternoon from WNW to near zonal.
Vis sat shows high based cu has developed across NE WY through the
Black Hills. Still can`t rule out an isolated shower or thunderstorm
over the Hills late this afternoon, but most areas will remain dry.
Overnight advection will bring warmer temps to the area on Memorial
Day. Highs will reach the upper 80s to lower 90s. Again, can`t rule
out an isolated afternoon shower or storm over the Hills, but
otherwise quiet weather is expected. Models continue to show a deep,
stationary upper low across in the vicinity of the Great Basin and
northern California through the middle and latter part of this week.
Good moisture transport from the Gulf sets up over the central to
northern Plains, bringing PWATs ranging from 125-175% of normal. The
moisture will be available...it`s just a matter of where the best
forcing sets up. The ECM continues to focus on the Dakotas while the
GFS targets WY, though there has been some shift eastward later in
the week closer to the ECM. Will continue to monitor the trends.
