AREAS AFFECTED...ERN MT AND WRN ND
CONCERNING...SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY
VALID 021954Z - 022100Z
STRONG LARGE SCALE FORCING IS BEGINNING TO OVERSPREAD ERN MT WHERE
WLY LOW LEVEL FLOW HAS YET TO SCOUR BOUNDARY LAYER MOISTURE. AS A
RESULT...TWO LINES OF CONVECTION HAVE DEVELOPED FROM NE OF HVR TO
WEST OF MLS. GIVEN THAT STEEP LOW LEVEL LAPSE RATES ARE IN PLACE
WITH SBCAPE ON THE ORDER OF 2000-3000 J/KG IT WOULD SEEM REASONABLE
TO EXPECT ONE OR MORE SQUALL LINES TO INTENSIFY AS CONVECTION
MATURES AND PROPAGATES TOWARD THE SK AND ND BORDERS. LARGE HAIL AND
DAMAGING WINDS ARE POSSIBLE WITH THIS ACTIVITY AND A SEVERE
THUNDERSTORM WATCH WILL LIKELY BE ISSUED TO ACCOUNT FOR THIS THREAT.
