DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0751 PM CDT SAT AUG 25 2007
VALID 260100Z - 261200Z
..THERE IS A SLGT RISK OF SVR TSTMS FROM A PORTION OF THE MID
ATLANTIC INTO THE NERN STATES...
..MID ATLANTIC THROUGH NERN STATES...
PRE-FRONTAL LINES OF STORMS CONTINUE OVER THE MID ATLANTIC AND NERN
STATES. THE WARM SECTOR REMAINS MODERATELY UNSTABLE WITH MLCAPE FROM
1500 TO 2500 J/KG. MODERATELY STRONG DEEP LAYER FLOW WILL PERSIST
OVER THE NERN STATES WITHIN ZONE OF LARGE SCALE ASCENT DOWNSTREAM
FROM EWD ADVANCING UPPER TROUGH. ALBANY 00Z WIND PROFILE SHOWS 30-40
KT UNIDIRECTIONAL WSWLY FLOW IN THE 1-6 KM LAYER WITH WEAKER UPPER
LEVEL WINDS. THIS PROFILE IS SUPPORTIVE OF FORWARD PROPAGATING
OUTFLOW DOMINANT STORMS WITH OCCASIONAL BOWING STRUCTURES CAPABLE OF
ISOLATED DAMAGING WIND. SOME OF THE STRONGER STORMS MAY ALSO PRODUCE
HAIL. THE SEVERE THREAT SHOULD PERSIST THROUGH ABOUT 03Z...BUT WITH
A GRADUAL DIMINISHING TREND AS THE BOUNDARY LAYER STABILIZES.
