Valid 221630Z - 231200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
The risk for thunderstorms appears negligible across the U.S. today
through tonight.
...Synopsis...
The upper troughing currently in place across much of the CONUS is
expected to persist throughout the day, reinforced by a shortwave
trough forecast to move southward across the Four Corner and into NM
and another shortwave trough that is expected to move southward
through the northern Rockies late tonight/early tomorrow. At the
surface, expansive and cold high pressure, currently centered over
western PA, will gradually shift eastward, while maintain offshore
flow along the East and Gulf Coasts. Cold high pressure is also in
place across the western CONUS. This area of high pressure will
likely strengthen throughout the period, potentially exceeding 1050
mb over eastern ID tomorrow morning. Dry and stable conditions
promoted by these features will preclude thunderstorm development.
