   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM FAR EASTERN
   MONTANA INTO NORTH DAKOTA...

   ...SUMMARY...
   A few severe storms remain possible this evening from far eastern
   Montana into North Dakota. Isolated strong storms may persist for a
   few hours over parts of the Northeast and Mid Atlantic, and from
   Idaho into southwest Montana.

   ...Northern Plains and Rockies...
   Scattered strong to severe storms persist near the wind shift over
   eastern MT, with isolated activity extending southeastward into
   western ND. The 00Z ABR sounding farther east shows strong
   instability, but with a cap below 700 mb.

   Lift will persist this evening as the shortwave trough moves across
   the area and the low-level jet strengthens and veers to
   southwesterly. While capping is a concern for storm coverage, the
   conditional threat of a severe storms remains high, with damaging
   hail or wind the most likely threat should additional storms form
   this evening. See mesoscale discussion 1325 for more information.

   ...Northeast and Mid Atlantic...
   Much of the air mass has been overturned by earlier convection, but
   pockets of moderate instability remain from MD into southern NY.
   Isolated strong wind gusts remain possible for a few hours until the
   boundary layer stabilizes.
