...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE CENTRAL GREAT PLAINS...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SURROUNDING THE
MODERATE RISK INTO THE SOUTHERN HIGH PLAINS AND ACROSS PARTS OF THE
NORTHEAST THIS EVENING...
...SUMMARY...
Severe thunderstorms will continue across the central Great Plains
tonight. The greatest tornado threat, including the potential for
strong tornadoes, will continue through late evening. Intense
damaging winds and very large hail are expected as well.
...Central Great Plains...
Numerous discrete supercells, and evolving convective clusters, are
noted from the NE Panhandle into central KS. Multiple reports of
tornadoes, several from long-lived supercells, have been observed
with convection that evolved along a baroclinic zone that has moved
little during the day. This boundary will continue to serve as the
focus for supercells tonight. Over the next few hours, LLJ should
strengthen across KS into south-central NE. This should encourage
one or more MCSs to evolve across the central Plains. Tornado threat
remains highest this evening with supercells, along with very large
hail; however, damaging wind threat should increase as an MCS
evolves and begins to surge southeast toward north-central KS.
...Northeast...
Widespread convection that evolved across the northeastern US has
overturned much of the buoyancy that developed during peak heating.
Remnant thunderstorm activity has progressed into southern New
England, arcing southwest into the Delmarva region. The southwestern
flank of this band of storms is shifting east within an environment
that remains fairly unstable, per 27/00z IAD sounding. Until this
air mass is overturned, or convection moves off the middle Atlantic
Coast, some severe threat will linger. Greatest risk over the next
few hours will be from portions of northern VA-southeast MD-DE. Wind
is the primary risk with these storms.
