....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
The risk for thunderstorms appears negligible across the U.S.
Thursday through Thursday night.

....Discussion...
Mid/upper flow will remain highly amplified across much of North
America through this period, as a prominent, blocking mid-level high
is generally maintained near coastal southeastern Alaska and British
Columbia.  The most notable belt of stronger downstream flow will
continue to emanate from the Arctic latitudes, around the  northern
and eastern periphery of the high, before continuing to evolve into
a broad, confluent cyclonic belt south of the western and central
Canadian/U.S. border through the Atlantic Seaboard.  Beneath this
regime, cold surface ridging likely will be reinforced, particularly
across the northern intermountain region and Great Basin into much
of the northern and central Great Plains, as well as southeastward
into the northern Gulf of Mexico, Southeast and Mid Atlantic.
