...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Tuesday or Tuesday night.

...Northeast...
Sporadic, low-topped thunderstorms may develop towards midday
through the afternoon within a post-frontal regime as 500-mb
temperatures fall at/below -28 C. This should occur to the west of
an intense mid-level jet that will progress quickly across the
Mid-Atlantic States and off the coast by evening. While the boundary
layer will be drying, scant buoyancy may persist where mid-level
lapse rates abruptly steepen. Much of the convection will probably
remain as scattered showers, with thunderstorm coverage expected to
be very isolated. Locally strong gusts could accompany this weak
convection at peak heating across southern New England. 

...Southwest...
A low-amplitude shortwave impulse should dampen as it moves from the
Lower CO Valley towards the southern Rockies. But adequate
large-scale ascent coupled with scant buoyancy should yield isolated
thunderstorms, mainly on Tuesday afternoon. Farther west, a separate
shortwave trough will approach but remain offshore of the CA coast.
Greater but still weak buoyancy from the Sierra NV Mountains across
northern CA may support isolated afternoon thunderstorms. Weak
deep-layer shear/ascent will minimize severe potential.
