.PREV DISCUSSION... /ISSUED 0150 AM CDT Wed Aug 17 2022/

...Synopsis...
An upper ridge will prevail across the western CONUS today as
mid-level troughing gradually amplifies across the eastern
two-thirds of the U.S. Multiple mid-level impulses will pivot around
the upper ridge, with a relatively pronounced impulse traversing the
Pacific Northwest Coastline. Deep-layer ascent across portions of
the Pacific Northwest will lift a monsoonal airmass atop a dry
boundary layer, encouraging high-based thunderstorm development by
early evening. Isolated dry thunderstorm highlights were added to
portions of northern California into southern Oregon and extreme
northwest Nevada given the confidence in dry thunderstorms occurring
atop very dry fuels. Otherwise, locally Elevated dry/windy surface
conditions may acco*pany the passage of a cold front across portions
of Montana and the northern High Plains through the day.
