AREA FORECAST DISCUSSION FOR CENTRAL/NORTHCENTRAL AND NORTHEAST SOUTH DAKOTA AND WEST CENTRAL MINNESOTA NATIONAL WEATHER SERVICE ABERDEEN SD 300 AM CDT TUE MAY 30 2000 MODELS FAIRLY SIMILAR AND POINT AT SIMILAR SOLUTIONS. AVN AND ETA CLOSEST WITH NGM A LITTLE FARTHER NORTH ON SURFACE FEATURES. COLD FRONT MOVES SOUTH OF THE ABERDEEN COUNTY WARNING AREA BUT UPPER LOW HANGS TO THE WEST OVER THE ROCKIES. SERIES OF MINOR WAVES MOVE THROUGH THE FLOW BUT ETA MODEL SOUNDINGS AND CAPE AND LIFTED INDEX FIELDS KEEP OUR AREA IN THE COLD STABLE SECTOR. WITH STATIONARY BOUNDARY LYING TO OUR SOUTH AND A STRONG SOUTHWEST FLOW AT 70H FEEL ETA PRECIPITATION FIELD LOOKS REASONABLE. SOME DIFFERENCE IN MODELS IN LOW LEVEL MOISTURE. AVN IS QUICKER TO DRY OUT THE LOW LEVELS. WILL GENERALLY USE A BLEND BUT TREND TOWARD THE DRIER AVN. HOWEVER CAN'T GO WITH THE MUCH WARMER FAN TEMPS. BELIEVE CLOUDS WILL BE EXTENSIVE ENOUGH TO HOLD TEMPERATURES CLOSER TO 60 TO 65 RANGE ADVERTISED IN FWC. FWC GENERALLY LOOKS PRETTY GOOD EXCEPT FOR SHORT RANGE POPS.
