…Synopsis…
Broad, longwave mid-level troughing across the western 1/3 of the
CONUS will result in areas of showers and a few thunderstorms – most
likely across portions of UT/CO/ID. Point forecast soundings
indicate appreciable boundary layer mixing with inverted-V low-level
profiles and strong deep shear, which may result in an isolated
strong wind gust. This threat should be too isolated/marginal for
any severe probabilities.
Farther northwest, cold air aloft will result in a few strikes
across western Washington State today through this evening.
Elsewhere, broad ridging aloft and a surface high centered over the
upper Ohio Valley should limit potential for deep convection across
the central and eastern U.S.
