Valid 191200Z - 201200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast across the contiguous United
States through tonight.
...Synopsis...
A mid-level low over AZ will slowly weaken and migrate eastward to
NM during the period. A mid-level ridge will extend northward from
northern CA into the Pacific Northwest. Farther east, broad
cyclonic mid-level flow will encompass the Upper Midwest
southeastward through the East Coast. Isolated to scattered
thunderstorms are possible mainly during the afternoon and evening
across the Desert Southwest/Four Corners. Surface high pressure
centered over the southern Great Plains into the Southeast will lead
to offshore flow and tranquil conditions in those areas.
