...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF
NORTH DAKOTA AND VICINITY...
...SUMMARY...
Scattered strong to severe thunderstorms remain capable of damaging
wind gusts and large hail across portions of the northern Plains.
Isolated strong to severe storms will also be possible from the
mid-Atlantic west through the Ohio Valley and central/southern
Plains, and across northern California and northwest Nevada.
...Northeast/mid-Atlantic...
Isolated strong/severe storms continue across PA in advance of a
weak frontal boundary, while storms farther east continue to move
offshore across portions of NJ/NY. Latest objective analysis shows
pockets of moderate instability (MLCAPE at or above 2000 J/kg)
across the northern Delmarva Peninsula, and some potential for a
stronger storm or two will exist in this area this evening. Overall,
the severe threat should remain isolated through the remainder of
the evening, and diminish thereafter with the onset of gradual
nocturnal cooling/increasing CINH.
...Western Oklahoma/Eastern Kansas into the OH Valley...
A few clusters of thunderstorms continue within a moderate/strongly
unstable air mass in the vicinity of a nearly stationary frontal
boundary from northern KS east across the OH Valley, and along a
confluence zone across western OK. The magnitude of instability will
remain sufficient for pockets of damaging wind potential with any
cluster that can become more organized this evening.
...Great Basin/Northern CA...
Thunderstorms will continue this evening within a weakly unstable
air mass east of an upper-level trough. Steep low-level lapse rates
will result in an isolated damaging wind risk with stronger
updrafts.
...Central/northern Plains...
A couple clusters of strong/severe thunderstorms continue in the
general vicinity of the MT/ND border region, with reports of large
hail over the past couple hours. These storms are located along the
southern periphery of somewhat stronger mid-level flow, and will
moving into a strongly unstable air mass over ND with MLCAPE in the
2000 to 4000 J/kg range. Storms continue to show signs of
organization this evening, and a more concentrated risk for damaging
winds and large hail will exist in association with recently issued
Severe Thunderstorm Watch 543.
