....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorm potential across the United States appears low on
Saturday.

....Synopsis...

Low-amplitude, quasi-zonal upper level flow will emerge across the
CONUS as a shortwave trough moves offshore the Atlantic coast early
Saturday. At the surface, low pressure centered over southern
portions of the Canadian Prairies will shift east, while a trailing
cold front moves across the northern Rockies/High Plains region. A
weak frontal zone across the FL Peninsula will dissipate, while
strong surface high pressure persists across the eastern U.S.
northern low-level flow across the western Atlantic and Gulf will
result in a dry and stable airmass across much of the U.S. east of
the Rockies.

Precipitation is more likely across portions of the Pacific
Northwest as moist onshore deep-layer flow  streams over the region.
Cold midlevels will result in steep lapse rates and meager elevated
instability. A lightning flash or two is possible along the WA coast
with low-topped convection, but thunderstorm coverage is expected to
remain less than 10 percent and more likely offshore.
