AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
606 PM CDT WED APR 9 2008

.MESOSCALE UPDATE...
THE SEVERE STORM MOVING TOWARD LAKE EUFAULA IS MOVING
RIGHT OF THE MEAN FLOW AS THE WARM FRONT IS WORKING
NORTH TOWARD THE I-40 CORRIDOR.  THE DEVIANT MOTION
NORTH OF THE WARM FRONT HAS RESULTED IN A STORM-RELATIVE
HELICITY TO 3KM FOR THIS CELL NEAR 800 M2/S2.  THE
HODOGRAPH AHEAD OF THE CELL HAS BECOME VERY FAVORABLE FOR
LOW-LEVEL STORM ROTATION.  IN ADDITION...THE REPORTS OF
STRONG WIND GUSTS NORTH OF THE WARM FRONT...LIKE THE
RECENT GUST AT BLACKWELL SUGGESTS THE WARM FRONT IS
VERY SHALLOW...SO IT IS LIKELY IT CAN BECOME SURFACE
OR NEAR SURFACE-BASED WITH TIME.

THE NEGATIVE FOR TORNADO PRODUCTION WITH THIS CELL
IS ITS COMPLEX START.  HOWEVER...WITH AN ALREADY
FAVORABLE ENVIRONMENT AND EXPECTED INCREASE IN THESE
PARAMETERS WITH TIME...THE CELL HAS INCREASING TORNADO
POTENTIAL.

ALL INTERESTS IN MCINTOSH AND NORTHERN PITTSBURG COUNTY
SHOULD MONITOR THIS CELL CLOSELY.
