AREAS AFFECTED...LOWER MI

CONCERNING...SEVERE THUNDERSTORM WATCH 150...

VALID 061822Z - 061945Z

IT APPEARS THAT THE SEVERE THREAT ACROSS THE WW 150 HAS DIMINISHED.
NEW CONVECTION IS NOT EXPECTED TO DEVELOP UNTIL LATER THIS AFTERNOON
AFTER THE EXPIRATION OF THE CURRENT WATCH. AS A RESULT...WW 150 WILL
BE CANCELLED.

OBJECTIVE ANALYSIS SHOWS A CAP IN PLACE ACROSS LOWER MICHIGAN. VIS
SATELLITE SHOWS CIRRUS ACROSS THE WATCH AREA AND THIS WILL SUPPRESS
SFC HEATING SOMEWHAT. AS A RESULT...THE CAP SHOULD HOLD THROUGH MID-
AFTERNOON. AS INSTABILITY INCREASES AND THE CAP WEAKENS BY LATE
AFTERNOON...SCATTERED SFC-BASED STORMS SHOULD DEVELOP. WHEN IT
APPEARS THIS WILL HAPPEN...A NEW WW MAY BECOME NECESSARY FOR LOWER
MI.
