...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast today.
...Discussion...
Highly amplified but progressive flow pattern aloft will continue
across the U.S. today. As a lead short-wave trough crosses the
Intermountain West, a second, eastern Pacific trough will move
onshore. Cold air aloft accompanying this feature will support
sufficient destabilization to allow a few thunderstorms to develop
within the broader area of precipitation accompanying this feature.
The greatest lightning potential should occur across northern and
central California, and across the Sierra into western Nevada.
Farther east, ridging initially extending across the Plains states
will move steadily eastward, as a downstream eastern U.S. trough/low
shifts gradually off the middle and southern Atlantic Coastal area
into the western Atlantic. Any deep moist convection associated
with this trough will remain well offshore.
