Thunderstorms are not expected on Thursday.

A broad and deep upper trough is forecast to cover much of the
western and central CONUS early Thursday morning, with modest upper
ridging in place east of this trough, from the TN Valley into
Quebec. Shortwave trough embedded within the larger parent trough is
expected to progress quickly eastward/northeastward from the central
Plains across the Mid MS Valley and Lower OH Valley, reaching the
Upper Great Lakes/Mid OH Valley by early Friday morning. Another
shortwave trough is expected to move through the western portion of
the parent trough, crossing the Great Basin and the Southwest and
reaching the Southern Plains by early Friday. This pattern evolution
will result in upper troughing across the entire CONUS by early
Friday morning.  

Surface low associated with the lead shortwave trough is forecast to
begin the period over eastern KS before moving quickly
northeastward. Expectation is for this low to be centered over the
Upper Great Lakes by early Friday morning. A cold front will extend
from this low and sweep quickly eastward as the low moves
northeastward. Some modest low-level moisture may precede this front
from the southern Plains across the Southeast, but warm temperatures
aloft and limited diurnal heating will temper buoyancy. As such, no
thunderstorms are currently expected.
