CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 080000Z - 080130Z
THUNDERSTORMS HAVE BEEN GRADUALLY INTENSIFYING/GROWING DEEPER ACROSS
NRN WI THIS EVENING WITHIN NW-SE ORIENTED BANDS OF CONVECTION. THIS
MIGHT BE DUE TO SLIGHTLY STRONGER BACKGROUND ASCENT SPREADING EWD IN
ASSOCIATION WITH THE PERTURBATION OVER MN. PARCELS FEEDING THESE
STORMS WERE EMANATING FROM A RESERVOIR OF 3000+ MLCAPES AND IT IS
POSSIBLE THAT MORE STORMS WILL INTENSIFY THIS EVENING AS THE SWLY
LLJ INCREASES. AIR MASS IS SHEARED SUFFICIENTLY FOR SUPERCELLS WITH
LARGE HAIL. ADDITIONALLY...VWP FROM GRB SHOWS MODEST LOW-LEVEL
CURVATURE TO THE HODOGRAPHS TO SUPPORT A TORNADO THREAT. STRONGER
STORMS WILL FAVOR AREAS OVER NCNTRL-CNTRL WI ALONG THE BACK-EDGE OF
THE ACTIVITY CLOSER TO THE WARM SECTOR.
