...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast for today.

...Synopsis...
Early-morning satellite imagery shows a pair of shortwave troughs
within in the cyclonic flow covering the central and eastern CONUS.
The southernmost shortwave is currently progressing southeastward
into the Lower MS Valley, with this southeastward motion expected to
persist throughout the day. This evolution takes the wave across the
north-central and eastern Gulf this afternoon/evening, and across FL
by early tomorrow morning. The northern shortwave is moving
southeastward over the Upper Great Lakes, and continued
southeastward progress will take this wave through the middle/upper
OH Valley and off the northern Mid-Atlantic coast tonight. Dry and
stable conditions associated with an arctic airmass will be in place
ahead of these shortwaves, limiting low-level moisture and
precluding thunderstorm development.

Another shortwave trough is currently moving eastward across the
interior Pacific Northwest and northern Great Basin. This
eastward/southeastward progression should continue, taking the wave
through the northern/central Rockies and into the central Plains
while also dampening the shortwave ridging proceeding it.
Precipitation will be possible in association with this shortwave
during the day and across the central and northern Rockies. However,
little to no instability is forecast, and thunderstorms appear
unlikely.

...DISCUSSION...
Severe weather is unlikely through the extended forecast period. A
highly amplified mid-level flow pattern over the CONUS will continue
through this weekend and into the first part of next week. A
prominent upper low will amplify over the East Coast as a strong
surface cyclone develops offshore. Ridging over the western US will
support strong high pressure and a cold/dry continental air mass
over much of the US. This will largely suppress inland moisture
transport, outside of far south FL, and subsequent thunderstorm
potential for the next several days.
