70S OVER WEST. MAIN AXIS OF CONVECTION AHEAD OF COLD FRONT STRETCHES
FROM JUST N OF TORONTO TO DETROIT AREA. THIS ACTIVITY MAY TEND TO
WEAKEN A BIT FURTHER REST OF MORNING BUT SHOULD REIGNITE AS IT
ENCOUNTERS BETTER INSTABILITY PARAMETERS AND MOVES TWD OUR CWA EARLY
THIS AFTERNOON. SO...WILL JUST MAINTAIN LIKELY POPS ALL AREAS BUT
USE FEW QUALIFIER AS MOST OF THE TIME WILL BE DRY. AS FOR SVR
POTENTIAL...CAPES NOT ALL THAT IMPRESSIVE...BUT MODEL CAPES MAY BE
UNDERESTIMATED AS THEY ARE BASED ON A CLOUDY DAY AND WE ARE GETTING
SOME SUNSHINE. ALSO...DECENT LL JET (40-45KTS AT 2K FT) OVER LOWER
