WITH A QUASISTATIONARY BOUNDARY EXTENDING NWWD TO THE DFW METROPLEX
AND THEN NNEWD ACROSS CENTRAL OK TO CENTRAL MO.  THIS BOUNDARY THEN
EXTENDS EWD AS A WARM FRONT ACROSS SRN PORTIONS OF IL/IN/OH.  

DEEP SLY FLOW TO THE EAST OF T.D. GRACE...WITH FLOW VEERING TO SWLY
ACROSS THE MID MS/LOWER OH VALLEY WILL CONTINUE TO ALLOW FOR
ABUNDANT MOISTURE ADVECTION TO THE LOWER MO/MID MS AND LOWER OH
VALLEYS THROUGH THE REST OF THE PERIOD.  INCREASING UPWARD MOTION
ACROSS THE LOWER MO TO LOWER OH VALLEYS WITH THE APPROACH OF THE
CENTRAL PLAINS UPPER SHORT WAVE TROUGH AND LOW-LEVEL CONVERGENCE

CONTINUE THROUGH THE EVENING AND POTENTIALLY OVERNIGHT GIVEN LOW
LCLS WITHIN THE TROPICAL AIR MASS...AND A SWLY 30 KT LLJ NOSING INTO
THE LOWER OH VALLEY RESULTING IN A FAVORABLE LOW-LEVEL SHEAR
ENVIRONMENT ESPECIALLY ALONG THE WARM FRONT.
