MESOSCALE DISCUSSION 1881

NWS STORM PREDICTION CENTER NORMAN OK

1152 AM CDT SUN AUG 07 2011

AREAS AFFECTED...SRN MD...WRN/CNTRL VA AND NC

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 071652Z - 071745Z

COVERAGE OF THUNDERSTORMS WILL GRADUALLY INCREASE THROUGH THE

AFTERNOON...WITH PRIMARY THREATS OF HEAVY RAINFALL AND STRONG TO

SEVERE WINDS.

AMPLE SURFACE HEATING IS OCCURRING TO THE LEE OF THE

APPALACHIANS...WITH HOT TEMPERATURES IN THE UPPER 80S TO LOWER 90S

CONTRIBUTING TO INCREASING INSTABILITY. ALTHOUGH INITIATION IS

ONGOING OVER THE APPALACHIANS...HI-RES MODEL CONSENSUS SUGGESTS MORE

ROBUST DEVELOPMENT WILL OCCUR AFTER 18-19Z. CURRENTLY WEAK FLOW

ALOFT SUGGESTS AN INITIAL PREDOMINANCE OF PULSE SEVERE...GRADUALLY

TRANSITIONING TO SEMI-ORGANIZED MULTICELLULAR CLUSTERS AS WLY FLOW

ALOFT BEGINS TO INCREASE. THESE CLUSTERS WILL THEN PROGRESS EWD TO

THE LEE OF THE APPALACHIANS...SPREADING TOWARDS THE COAST WITH TIME.

HOWEVER...VERY SATURATED DEEP LAYER PROFILES REFLECTED IN AREA 12Z

SOUNDINGS...CHARACTERIZED BY PWAT VALUES NEAR 2-2.25 INCH AND

SURFACE DEW POINTS FROM 70-79 F...SUGGEST THAT HEAVY RAINFALL MAY BE

THE PREDOMINANT THREAT...AND THEREFORE A WW ISSUANCE IS UNCERTAIN AT

THIS TIME. IF COLD POOLS CAN BECOME BETTER ORGANIZED...THEN A WIND

THREAT MAY BECOME MORE APPARENT AND A WW MAY BE CONSIDERED. WARM

TEMPERATURES ALOFT WOULD INDICATE LITTLE IF ANY HAIL THREAT EXISTS.

..HURLBUT.. 08/07/2011

i do like tuesday also.. tho it seems there is almost too much energy floating around throughout the day. i'd like to see it a little more consolidated so we don't screw it up with messiness.

still better than nothing. At least you get to hear thunder and see interesting storm clouds.

i suppose. we got enough rain to super sauna. hearing thunder and getting no rain is lose unless you're watching a tornado (apparently).
