SIMILAR TO YESTERDAY 12Z RAOB DATA SHOWS A VERY UNSTABLE AIR MASS (LI ~-9C)
AND RATHER COLD TEMPERATURES (-13.3C AT 500MB) ALOFT. WEAKER WINDS VIA
RAOB DATA SHOULD ALLOW FOR A FASTER ONSET TO THE EAST/WEST COAST SEA
BREEZES WITH DAYTIME HEATING AND SEA/OUTFLOW BOUNDARY COLLISIONS PROVIDING
FOCUS FOR SCATTERED SHOWERS AND THUNDERSTORMS DURING THE AFTERNOON AND
EARLY EVENING HOURS. SIMILAR TO YESTERDAY SOME OF THE THUNDERSTORMS
COULD BECOME STRONG WITH DAMAGING DOWNBURST WINDS AND HAIL A POSSIBILITY
GIVEN THE COLD TEMPERATURES ALOFT AND RATHER STEEP LAPSE RATES. IN
ADDITION A WEAK STEERING FLOW WILL SUPPORT SLOW MOVING STORMS...SO SOME
LOCALLY HEAVY RAINS WILL BE POSSIBLE.

The local forcast discussion would lead one to believe we get a second round today, however, in my experience the 'next' day after an unusual event (and one not adequately forcast) is usually not nearly the same. Too hard to get the 'exact' same atmospheric conditions from one day to the next. They WILL tend to forcast the same, just to cover themselves, though. This gets me wondering about the season to come as odd weather is usually NOT isolated for a season....no solid proof of it, but it SEEMS that way.
