DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1152 PM CST FRI JAN 11 2008
VALID 131200Z - 141200Z
..NO SVR TSTM AREAS FORECAST...
..SYNOPSIS...
A BROAD UPPER TROUGH WILL COVER THE CONUS ON SUNDAY...EXCEPT FOR AN
UPPER RIDGE ALONG THE PACIFIC COAST. WITHIN THIS UPPER TROUGH...A
VIGOROUS SHORTWAVE TROUGH IS FORECAST TO LIFT NEGATIVELY TILTED FROM
THE CENTRAL GULF STATES NEWD INTO THE MID ATLANTIC STATES.
..FL PENINSULA...
THE NEWD MOVING SHORTWAVE TROUGH WILL AID IN PUSHING A COLD
FRONT...CURRENTLY LOCATED ACROSS NRN FL...SEWD ACROSS THE FL
PENINSULA. A MOIST BOUNDARY LAYER AND WEAK INSTABILITY SHOULD
SUPPORT SCATTERED CONVECTION...AND PERHAPS EVEN A FEW THUNDERSTORMS
ALONG AND AHEAD OF THE FRONT. HOWEVER...WITH THE MAIN FORCING/MASS
CONVERGENCE LOCATED WELL NORTH OF FL AND FORECAST OF POOR MID LEVEL
LAPSE RATES...THE SEVERE POTENTIAL APPEARS LIMITED.
..VA NEWD INTO SRN NY...
DESPITE A COOL AND STABLE BOUNDARY LAYER...THE APPROACHING SHORTWAVE
TROUGH WILL RESULT IN STRONG WARM ADVECTION AND LIFT BETWEEN 750-850
MB AND MAY STEEPEN MID LEVEL LAPSE RATES SUFFICIENTLY FOR A SMALL
POSITIVE AREA ALOFT. THIS POSITIVE AREA IS NOT EXPECTED TO HAVE
ENOUGH VERTICAL DEPTH FOR MORE A LIGHTNING STRIKE OR TWO.
