A WAVE MOVING THROUGH THE RIDGE IS BEGINNING TO PRODUCE SOME SHOWERS AND THUNDERSTORMS ACROSS WYOMING. SURFACE HIGH IS EAST OF THE CWA...WITH THE SURFACE LOW MOVING IN FROM IDAHO. WINDS ARE LIGHT AND SOUTHERLY WITH TEMPS RISING INTO THE UPPER 70S AND LOWER 80S. THUNDERSTORMS...SOME OF WHICH MAY BE SEVERE WITH LARGE HAIL AND STRONG WINDS...ARE EXPECTED TO MOVE INTO NORTHEAST WYOMING THIS AFTERNOON AS THE SHORTWAVE PUSHES THROUGH THE RIDGE. HIGHEST MLCAPE VALUES OF 1500 TO 2000 J/KG WILL BE MAINLY ACROSS NORTHEAST WYOMING AND SOUTHERN SOUTH DAKOTA. BEST 0-6 KM SHEAR OF 35-40 KTS IS EXPECTED OVER NORTHERN SOUTH DAKOTA AND NORTHEAST WYOMING LATE THIS AFTERNOON AND THIS EVENING. STRONGEST CAP EXISTS ACROSS NORTHERN SOUTH DAKOTA...AND SO STORMS SHOULD REMAIN FARTHER SOUTH. MODELS ARE IN DISAGREEMENT ABOUT WHETHER STORMS ACROSS NORTHEAST WYOMING WILL MAKE IT INTO SOUTH DAKOTA...ESPECIALLY AFTER 00Z. WITH CAPE PREDICTED TO PERSIST ACROSS SOUTHERN SOUTH DAKOTA INTO THE EVENING AND A LOW-LEVEL JET INCREASING DURING THE NIGHT...EXPECT STORMS TO CONTINUE INTO THE EVENING AND MOVE EASTWARD OVERNIGHT AS THE WAVE PUSHES THROUGH. ON WEDNESDAY...THE PRESSURE GRADIENT WILL TIGHTEN AS THE SURFACE LOW CONTINUES MOVING INTO THE REGION. SOUTHEAST WINDS WILL BECOME BREEZY ACROSS THE SOUTH DAKOTA PLAINS. LOOKS LIKE A MARGINAL WIND ADVISORY EVENT...SO LATER SHIFTS WILL NEED TO EXAMINE THAT POSSIBILITY FURTHER. THE SOUTHERLY WINDS WILL ADVECT WARM AND MOIST AIR INTO THE AREA...WITH HIGHS IN THE 80S TO LOWER 90S AND DEW POINTS ACROSS THE SOUTH DAKOTA PLAINS IN THE LOWER 60S. A DRY LINE SETS UP ALONG THE WY/SD BORDER BY WEDNESDAY EVENING.

THUS...MOSTLY DRY CONDITIONS AND WARM TEMPS. UPPER LEVEL LOW OVER THE PAC NW/NRN ROCKIES AND UPPER RIDGE TO OUR EAST WILL REMAIN IN PLACE THROUGH THE FIRST PART OF THE WEEKEND...WITH A NEARLY DAILY CHANCE FOR TSTMS UNDER CONTINUED SW FLOW ALOFT. FLOW THEN BECOMES INCREASINGLY ZONAL FOR THE END OF THE WEEKEND INTO EARLY NEXT WEEK AS UPPER LOW PASSES TO OUR NORTH...LEADING TO SMALLER CHANCES FOR TSTMS. EVEN WARMER WEATHER BEGINS TO BUILD IN EARLY NEXT WEEK AS UPPER RIDGE BEGINS BUILDING INTO THE NRN ROCKIES/NRN PLAINS. && .AVIATION...FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING ISSUED AT 526 PM MDT TUE JUN 18 2013 VFR CONDITIONS EXPECTED MOST OF THE PERIOD.
