...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe weather is not expected today.
...Discussion...
A broad zone of cyclonic flow aloft will cover much of the western
and central U.S. today, as a short-wave trough moves quickly across
the southern Rockies and into the central Plains, and a second --
over the eastern Pacific -- reaches the West Coast overnight.
Meanwhile, downstream ridging will shift gradually eastward across
the eastern States.
At the surface, a central High Plains low will progress
northeastward across the central Plains, reaching the Mid Missouri
Valley vicinity late. A second low is forecast to move into central
California overnight.
Showers -- and possibly a few sporadic lightning flashes -- will
accompany the progression of the aforementioned/lead short-wave
trough across the Four Corners area through the day, and then with
some possible/elevated convection developing across the Mid Missouri
Valley area late. Meanwhile, showers -- and possibly a few
lightning flashes -- will also occur across portions of California,
ahead of the eastern Pacific trough. Overall, however, it currently
appears that coverage of any lightning will remain below 10% across
these areas. Elsewhere, thunderstorms are not expected.
