CONCERNING...SEVERE THUNDERSTORM WATCH 789...
VALID 020356Z - 020530Z
CORRECTED FOR TIME REFERENCE
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 789
CONTINUES.
THE POTENTIAL FOR ISOLATED SEVERE STORMS CAPABLE OF HAIL AND LOCALLY
DAMAGING WINDS CONTINUES ACROSS WW AREA.
ISOLATED TSTMS OVER MCLEAN AND SRN MERCER/WRN OLIVER COUNTIES HAVE
SHOWN A WEAKENING TREND AS OF 0350Z...PERHAPS IN ASSOCIATION WITH
STRENGTHENING CAP ACROSS THE AREA. HOWEVER...WATER VAPOR IMAGERY
SUGGESTS THAT A LOW AMPLITUDE IMPULSE IS CURRENTLY LIFTING NEWD
THROUGH S-CNTRL MT WITH A DOWNSTREAM ZONE OF FORCING FOR ASCENT
SUPPORTING ISOLATED TSTM DEVELOPMENT NW OF MLS. THIS IMPULSE SHOULD
CONTINUE NEWD OVERNIGHT...POTENTIALLY SUPPORTING ADDITIONAL TSTM
DEVELOPMENT ALONG WRN EDGE OF LOW-LEVEL INSTABILITY AXIS OVER FAR
WRN ND. CURRENT BIS VWP AND RUC FORECAST HODOGRAPHS INDICATE THAT
VERTICAL SHEAR REMAINS RELATIVELY STRONG AND THE POTENTIAL WILL
EXIST FOR SUPERCELLS SHOULD ADDITIONAL STORMS DEVELOP AND BECOME
SUSTAINED.
