...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE COLORADO/WYOMING FRONT RANGE AND THE MID-ATLANTIC...

...SUMMARY...
A few strong storms capable of large hail and damaging wind gusts
are possible in portions of the Colorado/Wyoming Front Range and
storms capable of damaging wind gusts are possible in the
Mid-Atlantic.

...Synopsis...
Upper-level ridging is forecast to strengthen across the central
CONUS on Thursday. A large trough across southeast Canada will shift
southeast across the Northeast with moderate mid-level flow
overspreading the Mid-Atlantic. A surface cold front will extend
from the Mid-Atlantic to the Southern Plains and then into the
central High Plains.

...Central High Plains...
Moderate to potentially strong instability is forecast to develop
across the central High Plains with very steep mid-level lapse
rates. Moderately strong mid/upper-level flow will provide ample
shear. Therefore, as storms develop across the higher terrain and
intensify as they encounter the greater instability east of the
Mountains, they are also expected to become more organized, with the
potential for some supercell structures. The steep mid-level lapse
rates, relatively low freezing level, and favorably located buoyancy
within the hail growth zone will all support the potential for
isolated large hail. In addition, a deeply mixed boundary layer will
also support some damaging wind gusts.

...Mid-Atlantic...
Hot conditions are forecast ahead of a surface front in the
Mid-Atlantic with temperatures in the mid 90s and dewpoints in the
mid 60s. This will result in moderate to strong instability by early
afternoon. Storms are expected to develop along the front by early
afternoon and organize into a broken line. Isolated damaging wind
gusts are possible from these storms during the afternoon to early
evening due to a combination of a deeply mixed boundary layer and
high moisture content (2+" PWAT).
