...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN A CORRIDOR

EAST OF THE SOUTHERN ROCKIES THROUGH THE CENTRAL GREAT

PLAINS...OZARK PLATEAU...AND TENNESSEE VALLEY...



...SUMMARY...

Clusters of thunderstorms accompanied by a risk for damaging wind

gusts may evolve in a corridor across parts of the central Great

Plains into Tennessee Valley Friday afternoon and evening.



...Discussion...

To the southeast of a significant digging trough offshore of the

British Columbia and Pacific Northwest coast, models continue to

indicate that an increasingly prominent mid/upper-level high may

begin to form across portions of the Colorado Valley/Plateau through

southern Rockies vicinity.  Ridging is also forecast to continue

building along an axis northward through the northern U.S. Great

Plains and eastern Canadian Prairies Friday through Friday night,

while positively tilted larger-scale downstream troughing gradually

shifts into and across the northern Atlantic Seaboard.



The evolution of weak remnant troughing across the lower Missouri

Valley and central Great Plains remains much more unclear.  However,

guidance generally suggests that a belt of convectively augmented

mid-level flow will linger across southern portions of the central

Great Plains through Tennessee Valley, and perhaps through southern

Mid Atlantic coastal areas.



The potential for at least moderate destabilization appears most

certain along the southern periphery of this regime, aided by a

corridor of steeper lower through mid-tropospheric lapse rates

associated with elevated mixed-layer air (probably based closer to

850 mb than 700 mb), above a seasonably moist boundary-layer. 

Focused in zones of strengthening differential heating across a

remnant outflow boundary, or boundaries, the environment might

become conducive to the evolution of at least small organizing

clusters with potential to produce strong to severe surface gusts

Friday afternoon and evening.
