AREAS AFFECTED...CENTRAL DAKOTAS
CONCERNING...TORNADO WATCH 294...
VALID 100018Z - 100215Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 294 CONTINUES.
SUMMARY...DAMAGING WIND POTENTIAL INCREASING ACROSS NORTHERN
PORTIONS OF WW294 IN CENTRAL NORTH DAKOTA. TORNADO POTENTIAL MAY
INCREASE OVER THE NEXT COUPLE OF HOURS.
DISCUSSION...THUNDERSTORM DEVELOPMENT CONTINUES ALONG THE COLD FRONT
IN THE CENTRAL DAKOTAS THIS EVENING. MODE HAS FAVORED QUICK
TRANSITION FROM SUPERCELL TO CLUSTERS GIVEN MEAN LAYER SHEAR VECTORS
LARGELY PARALLEL TO THE FRONT. NONETHELESS, A FEW SUPERCELLS HAVE
PRODUCED HAIL UP TO 1.5-3 INCHES IN DIAMETER.
ACROSS CENTRAL NORTH DAKOTA, RADAR ANALYSIS SHOWS THE CLUSTER IN
WARD/MCLEAN COUNTY DEVELOPING A BOWING STRUCTURE, WITH WINDS AROUND
60-75 KTS AROUND 1 KFT AS VIEWED FROM KBIS AND KMBX. WINDS UP TO 72
MPH HAVE BEEN REPORTED NEAR SAWYER, ND. THE AREA AHEAD OF THIS LINE
WILL BE A FAVORED REGION FOR SIGNIFICANT DAMAGING WIND (75-80+ MPH)
POTENTIAL IN THE SHORT TERM DUE TO STEEP LOW LEVEL LAPSE RATES,
EVAPORATIVE PROCESSES, AND FAST STORM MOTIONS WITH THESE STORMS.
TORNADO POTENTIAL CONTINUES AND MAY INCREASE THROUGH THE EVENING.
INITIAL STORMS DEVELOPED IN THE LOWER DEW POINT AIR MASS ACROSS THE
WESTERN DAKOTAS AND ARE NOW MOVING INTO A REGION OF RICHER LOW-LEVEL
MOISTURE. WHILE THE MODE MAY NOT FAVOR MAINTENANCE OF DISCRETE
CELLS, LINE EMBEDDED CIRCULATIONS WILL POSE POTENTIAL FOR TORNADOES
THROUGH THE EVENING AS THE LOW-LEVEL JET ENHANCES LOW LEVEL SRH.
