...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected across the U.S. today or tonight.

...Synopsis...
Cyclone currently centered over northern NY/far eastern ON is
forecast to continue northeastward today, moving off the ME coast by
this evening. Northwesterly flow aloft will cover much of the
central and eastern CONUS in the wake of this cyclone, with a
low-amplitude shortwave trough moving within this northwesterly flow
from the northern Plains through the OH Valley. At the same time,
ridging will build over the western CONUS.

A dry and stable continental airmass will prevail across the CONUS
today, with notable airmass modification beginning across the
southern and central Plains. Strong surface high pressure currently
over the Southeast will result in offshore trajectories throughout
the first half of the period. As this high shifts
eastward/southeastward, southerly flow and moisture return will
begin across the TX Coast. Even with this moisture return, stable
conditions are expected to prevail, with no thunderstorms expected
across the CONUS today or tonight.
