AREAS AFFECTED...NERN CO...FAR SERN WY...NWRN KS...SWRN NEB

CONCERNING...SEVERE THUNDERSTORM WATCH 310...

VALID 140046Z - 140145Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 310
CONTINUES.

SUMMARY...BROKEN LINE OF TSTMS WILL CONTINUE TO PROPAGATE N-NEWD AND
WILL BEGIN MOVING OUT OF PARTS OF WW 310 WITHIN THE NEXT HR. THE
PRIMARY THREAT WILL BE DMGG WIND GUSTS...ALTHOUGH ISOLATED INSTANCES
OF LARGE HAIL AS WELL AS A TORNADO ARE POSSIBLE.

DISCUSSION...RADAR MOSAIC SHOWS BROKEN LINE OF TSTMS ALONG A COLD
POOL PROPAGATING N-NEWD TOWARDS NERN CO/SWRN NEB. DMGG WIND GUSTS
REMAIN THE PRIMARY THREAT WITH THIS ACTIVITY...ALTHOUGH THIS
POTENTIAL MAY BE SOMEWHAT LIMITED BY DISCONTINUOUS CHARACTER OF
CONVECTION ALONG THE COLD POOL. A LESSER THREAT FOR LARGE HAIL AND A
TORNADO MAY ALSO ACCOMPANY STRONGER/MORE DISCRETE TSTMS...GIVEN
BACKED SELY SFC WINDS NOTED IN RECENT OBSERVATIONS. IT IS UNCERTAIN
HOW LONG THIS LINE WILL BE ABLE TO MAINTAIN CURRENT INTENSITY
DOWNSTREAM /INTO SWRN NEB/...WITH A SIGNIFICANT CAPPING INVERSION
NOTED ON 13/00Z LBF SOUNDING. HOWEVER...DMGG WIND THREAT MAY EXTEND
OUTSIDE CURRENT WW 310 FOR AT LEAST THE NEXT 1-2 HRS...AND COULD
REQUIRE ISSUANCE OF A NEW WW IF CONVECTIVE TRENDS WARRANT.
