AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 311 PM MDT TUE JUN 12 2012 .DISCUSSION...CURRENT SURFACE ANALYSIS SHOWS LOW PUSHING THROUGH MONTANA. THE INCOMING LOW HAS CAUSED THE PRESSURE GRADIENT TO TIGHTEN...BREEZY SOUTHERLY WINDS ACROSS PORTIONS OF WESTERN SOUTH DAKOTA. WATER VAPOR IMAGERY SHOWS AN UPPER LEVEL SHORT WAVE MOVING THROUGH THE FORECAST AREA...ISOLATED SHOWERS AND THUNDERSTORMS DUE TO DECENT AMOUNTS OF INSTABILITY ARE EXPECTED OVER NORTHEAST WYOMING AND WESTERN SOUTH DAKOTA. DUE TO SHEAR AND INSTABILITY...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE SOUTHERN HALF OF WESTERN SOUTH DAKOTA. THE GREATEST THREATS WILL BE LARGE HAIL AND STRONG WINDS...WITH A SLIGHT POSSIBILITY OF ISOLATED TORNADOES. STORMS ARE ALSO EXPECTED TO FORM OVER THE BLACK HILLS AREA...AND THEN MOVE EASTWARD WITH THE WAVE. SOUTHERLY WINDS WILL AID IN STORM FORMATION THROUGH MOISTURE ADVECTION.

STORMS SHOULD CLEAR OUT ON THURSDAY...EXCEPT FOR THE SLIGHT POSSIBILITY OF TERRAIN-ENHANCED STORMS OVER THE BLACK HILLS. ANOTHER SHORT WAVE APPROACHES THE AREA THURSDAY NIGHT...BRINGING THE CHANCE FOR MORE NOCTURNAL THUNDERSTORMS. HIGH TEMPERATURES FOLLOWING THE FRONT WEDNESDAY NIGHT WILL BE SLIGHTLY COOLER...BUT REMAIN IN THE MID 70S TO MID 80S. EXTENDED...A NEARLY STATIONARY UPPER TROUGH WILL REMAIN WEST OF THE FORECAST AREA THROUGH THE WEEKEND RESULTING IN SOUTHWESTERLY FLOW ALOFT OVER THE AREA.
