...no severe thunderstorm areas forecast...
...summary...
organized severe thunderstorms are currently not expected on
thursday.
... synopsis ...
the closed mid-level low off the coast of the pacific northwest will
begin to lift north/northeast on thursday. as it does, strong
southerly mid-level flow will force height rises across the northern
us rockies and southwest canada. these rising heights will allow the
mid-level ridge across much of the us to redevelop northwestward
--from the midwest toward the northern us rockies.
at the same time, the second strong mid-level trough this week will
move across new england, bringing with it a reinforcing shot of
seasonably cool and dry air. a surface cold front will push
southward through new england, ending up in the vicinity of the
mid-atlantic by friday morning.
the airmass across much of the us, especially areas east of the
rockies, will be very warm and moist with afternoon temperatures
generally 5-15 degrees above normal outside of areas with widespread
cloud cover and precipitation. mid-level flow will be generally weak
across areas of the us with adequate buoyancy for thunderstorm
development. thus, the severe weather potential on thursday remains
too low to warrant unconditional severe weather probabilities.
