AREAS AFFECTED...NORTHEAST SOUTH DAKOTA...FAR SOUTHEAST NORTH
DAKOTA...WEST-CENTRAL MINNESOTA
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 071429Z - 071630Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...ISOLATED LARGE HAIL IS POSSIBLE AS CONVECTION MOVES
EASTWARD OVER THE NEXT 1-3 HOURS. A WATCH IS NOT CURRENTLY EXPECTED,
BUT TRENDS WILL BE MONITORED INTO THE AFTERNOON.
DISCUSSION...A SMALL CLUSTER OF STORMS IS MOVING EASTWARD ON THE
COOL SIDE OF A STATIONARY BOUNDARY. WEAK WARM ADVECTION IS LIKELY
SUPPORTING THIS ACTIVITY. GIVEN THE STEEP MID-LEVEL LAPSE RATES AND
MODEST ELEVATED BUOYANCY, ISOLATED LARGE HAIL IS POSSIBLE WITH THE
STRONGEST STORM CORES. 850 MB WINDS ARE EXPECTED TO WEAKEN SLIGHTLY
OVER THE NEXT COUPLE OF HOURS. AT LEAST IN THE SHORT TERM, IT IS NOT
LIKELY FOR ENOUGH OF A COLD POOL TO DEVELOP TO MAINTAIN ORGANIZATION
OR FOR THE BOUNDARY TO LIFT NORTHWARD AND STORMS TO BECOME SURFACE
BASED. DESTABILIZATION IS OCCURRING FARTHER EAST AND THE BOUNDARY
ORIENTATION COULD ALLOW THIS CLUSTER TO INTERACT WITH IT BY MID
AFTERNOON. OBSERVATIONAL TRENDS WILL CONTINUE TO BE MONITORED.
