...NO SEVERE THUNDERSTORM AREAS FORECAST...
Severe thunderstorms are not expected across the contiguous U.S. for
Friday and Friday night.
...Synopsis and Discussion...
A strong mid-level speed maximum is forecast to advance across the
Pacific Northwest. Related ascent may combine with marginal buoyancy
emanating from the Pacific marine layer in support of isolated
thunderstorms, affecting parts of coastal WA and OR and the adjacent
Lake-effect snow bands, perhaps associated with a modest convective
enhancement, may persist over the Great Lakes region. However,
present indications are that thunderstorm potential with this
activity should be minimal, given limited over-lake fetch length
(especially when compared to Day 1/Thursday for Lakes Erie and
Ontario), and an overall dearth of buoyancy based on forecast
Otherwise, dry/stable conditions will extend across much of the U.S.
on Friday, precluding thunderstorm potential.
