UPPER LEVEL ANALYSIS HAS LARGE TROF STILL SITTING OVER THE GREAT LAKES REGION...WITH HIGH PRESSURE OVER THE SOUTHWESTERN CONUS. NEAR ZONAL FLOW ALOFT IS IN PLACE ACROSS THE ROCKIES AND NORTHERN HIGH PLAINS. WEAK SHORTWAVE IS MOVING EASTWARD ACROSS NORTH CENTRAL WY RIGHT NOW. SHOWERS AND STORMS ARE DEVELOPING ACROSS EASTERN WY...WITH OTHERS TRYING TO DEVELOP OVER THE NORTHERN HILLS NOW. THIS WAVE...COMBINED WITH THE FRONT OVER THE AREA...WILL COMBINE TO BE THE FOCUS FOR CONVECTION ACROSS THE AREA LATER THIS AFTERNOON AND INTO TONIGHT. SKIES ARE SUNNY TO PARTLY CLOUDY NOW WITH TEMPS MOSTLY IN THE 80S. LOOKS LIKE A FAIRLY ACTIVE WX PATTERN CAN BE EXPECTED FOR MUCH OF THE WEEK INTO THE HOLIDAY WEEKEND AS NEAR ZONAL FLOW CONTINUES TO BRING A SERIES OF DISTURBANCES OVER THE REGION. ANY STORMS THAT DEVELOP WILL HAVE THE POTENTIAL TO BE STRONG TO SEVERE...ESPECIALLY DURING THE AFTERNOON AND EVENING HOURS. FOR LATE THIS AFTERNOON AND EVENING...STORMS WILL CONTINUE TO DEVELOP ACROSS THE WESTERN CWA AS WAVE MOVES ACROSS AND INTERACTS WILL INSTABILITY AXIS EAST OF THE BOUNDARY ACROSS FAR NORTHEAST WY AND WESTERN SD. CAP WILL CONTINUE TO WEAKEN LATE THIS AFTERNOON ACROSS NORTHEAST WY AND THE HILLS AREA. CAPE OF AROUND 2000 J/KG ARE IN PLACE ACROSS PORTIONS OF FAR WESTERN SD. SHEAR WILL BE STRONG ENOUGH FOR POTENTIAL SUPERCELL DEVELOPMENT. THREAT FOR SEVERE STORMS SHOULD BE HIGHEST FROM THE BLACK HILLS AREA AND FAR SOUTHEAST MT INTO THE FAR WESTERN DAKOTAS AND NEB PANHANDLE. PRECIPITABLE WATER VALUES WILL BE NEAR OR SLIGHTLY ABOVE NORMAL ACROSS WESTERN SD...SO A FEW STORMS COULD DROP LOCALLY HEAVY RAINFALL. STORMS SHOULD DECREASE IN INTENSITY AND COVERAGE OVERNIGHT AS WAVES MOVES EAST INTO MORE STABLE ATMOSPHERE. LOWS WILL BE IN THE 50S AND LOWER 60S. MORE STRONG TO SEVERE STORMS ARE POSSIBLE ACROSS PORTIONS OF THE AREA WEDNESDAY AFTERNOON AND EVENING AS ANOTHER WEAK WAVE PASSES OVER NEARLY STATIONARY BOUNDARY LATER IN THE DAY. MAIN THREAT FOR SEVERE STORMS SHOULD BE FROM THE HILLS AREA SOUTH AND EASTWARD WHERE INSTABILITY AND SHEAR WILL BE STRONGEST. HIGHS WILL BE IN THE 80S ACROSS THE PLAINS...70S IN THE HILLS. TIMING OF WAVES BECOMES MORE UNCERTAIN BEYOND WEDNESDAY...SO POP CHANCES BECOME MORE BROADBRUSHED. THERE COULD BE MORE OF A THREAT FOR OVERNIGHT AND MORNING SHOWERS AND STORMS AS WE GET INTO THE LATTER PART OF THE WEEK. CHANCES FOR SHOWERS AND STORMS ARE STILL EXPECTED LATER THURSDAY AND THURSDAY NIGHT. THREAT FOR STRONGER STORMS LOOKS RATHER MINIMAL AT THIS POINT WITH LESS INSTABILITY IN PLACE AND WEAKER SHEAR...BUT THIS COULD CHANGE AS TIME GOES ON. HIGHS AGAIN WILL BE IN THE 80S...70S IN THE HILLS. EXTENDED...A RATHER ACTIVE PATTERN WILL CONTINUE THROUGH THE HOLIDAY WEEKEND AS SEVERAL DISTURBANCES MOVE THROUGH THE FLAT RIDGE THAT WILL BE IN PLACE OVER THE NRN ROCKIES AND NRN PLAINS. THIS WILL LEAD TO A DAILY CHANCE FOR TSTMS. FLOW ALOFT WILL MOSTLY BE WLY OR NWLY WHICH SHOULD KEEP TEMPS CLOSE TO AVERAGE. && .AVIATION...SCT TSTMS ARE EXPECTED INTO THIS EVE...ESPECIALLY AROUND THE BLKHLS...WHICH MAY BRING SOME AREAS OF MVFR CONDITIONS.
