...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are unlikely today.

...Synopsis...
Several shortwave troughs are forecast to progress eastward today
within the cyclonic flow aloft covering much of the central and
eastern CONUS. At the same time, upper ridging will move eastward
across the western CONUS to the Intermountain West and a strong
shortwave trough will move across the Pacific Northwest. This
evolution will lead to a modestly amplified trough/ridge/trough
pattern over the CONUS by early tomorrow. 

Even with this relatively progressive pattern, the extensive and
cold airmass in place over much of the CONUS will promote offshore
trajectories and cold/stable sensible weather. Strongest convection
today is anticipated with a frontal band attendant to the Pacific
Northwest shortwave trough. However, this convection will still be
too shallow to produce lightning.

...DISCUSSION...
Severe weather potential in the extended forecast period is very
low. Broad-scale eastern US troughing will strengthen this weekend
as a clipper-style trough dives out of Canada an rapidly intensifies
along the Eastern Seaboard. A surface low will develop over the
eastern Gulf and rapidly deepen over the western Atlantic into early
next week. Western US ridging and strong surface high pressure over
the central US will keep substantial inland moisture return unlikely
for the foreseeable future.
