....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM EASTERN
WYOMING INTO SOUTHWEST NEBRASKA AND NORTHWEST KANSAS...

....SUMMARY...
Scattered severe storms producing hail remain possible this evening
mainly from Wyoming into Nebraska. Isolated severe storms may impact
parts of western Kansas and central Texas in the near term.

....Eastern WY into southern NE and western KS...
A few severe storms are ongoing from near the WY/MT border into
southwest NE. Steep lapse rates aloft and effective shear near 50 kt
exists across the region, which is aiding hail production. Severe
potential will likely persist for a few more hours across the
region, and perhaps into the night over the northern High Plains
where a midlevel disturbance will aid lift.

....Central TX to the middle TX Coast...
Scattered storms persist near  weak surface trough over central TX,
with marginal, short-lived hail cores at times and gusty outflow
winds. Given minimal lift across the area, a general downtrend is
anticipated through the evening.

....Northeast...
Scattered thunderstorms persist from eastern PA into southern New
England this evening, within a moist air mass and beneath relatively
cool midlevel temperatures. Shear is weak and given the loss of
heating, a continued downtrend is likely with the existing storms.
For additional information see mesoscale discussion 2128.
