...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected through Friday night.

...Coastal NC/southeast VA...
Ongoing convection across the southern Appalachians and adjacent
Piedmont will subside as storms progress east towards the southeast
VA to NC coast through sunrise, amid a meagerly buoyant air mass.
There is a low probability that this activity may linger in the
12-13Z period, before entirely vacating the coast.

...Southern ID/northern UT/western WY...
A lower-amplitude shortwave impulse will move across the northern
Great Basin towards the north-central Rockies by afternoon.
Downstream of this wave, warm-moist advection near 700 mb beneath
cooling mid/upper-level temperatures may foster scant buoyancy later
this morning into the afternoon. Despite marginal temperatures for
mixed-phase parcels, very isolated thunderstorms are possible over
the Snake River Plain and northeast Great Basin vicinity.
