THE 00Z KUNR SOUNDING HAD 3086 J/KG MLCAPE BUT -22 J/KG MLCIN. VERY WEAK RIDGING AND BUILDING HEIGHTS THIS AFTERNOON...COMBINED WITH THE MLCIN...HAS KEPT A DAMPER ON THE STORMS. HOWEVER...THE LOW-LEVEL JET IS STARTING TO INTENSIFY...AND THIS WILL LEAD TO RAPID AND WIDESPREAD STORMS DEVELOPING OVER SWRN/SCNTRL SD IN THE NEXT FEW HOURS...WITH STORMS LIKELY LASTING WELL PAST MIDNIGHT. CURRENT FORECAST IS IN DECENT SHAPE SO NO UPDATES ARE PLANNED OTHER THAN FOR POTENTIAL WATCH BOXES. PREVIOUS DISCUSSION...CURRENT SURFACE ANALYSIS PLACES LOW OVER WESTERN SASKATCHEWAN WITH TROF/BOUNDARY DROPPING THROUGH WRN ND INTO FAR WRN SD/ERN WY. UPPER LEVEL ANALYSIS PLACES LOW NEAR THE ALBERTA/SASKATCHEWAN BORDER WITH VARIOUS WEAK WAVES ROTATING AROUND IT...WITH THE CLOSEST ONE NOTED NEAR THE BIGHORNS. TCU STARTING TO DEVELOP OVER NRN PTNS OF THE BLKHLS INVOF AFOREMENTIONED BOUNDARY. FOR THIS AFTERNOON/TONIGHT...CONVECTION WILL CONTINUE TO DEVELOP OVER THE BLKHLS...WITH ADDITIONAL STORMS EXPECTED TO DEVELOP AS AFOREMENTIONED WAVE CONTINUES ITS APPROACH. THOUGH COVERAGE IS NOT EXPECTED TO BE AS WIDESPREAD AS YESTERDAY...ANY STORM THAT DOES DEVELOP WILL HAVE SEVERE POTENTIAL. INSTABILITY REMAINS PLENTIFUL (~1.5-2.5 KJ/KG) THIS AFTERNOON/EVENING AND SHEAR WILL CONTINUE TO INCREASE THROUGH THE AFTERNOON INTO THE EARLY EVENING...PLENTY TO SUPPORT ROTATING UPDRAFTS. LATER TONIGHT...LOW LEVEL JET STARTS TO TAKE SHAPE WHICH SHOULD KEEP SOME CONVECTION GOING. ON SUNDAY...UPPER LOW PUSHES OVER CENTRAL SASKATCHEWAN EARLY BEFORE OPENING UP. SHORT WAVE AHEAD OF PRIMARY WAVE SLIDES WELL INTO THE AREA BY MID-DAY WHILE AFFILIATED COLD FRONT STARTS TO SAG SOUTHEASTERLY WITH SHOWERS AND THUNDERSTORMS DEVELOPING. THE POSITION OF THE FRONT ALONG WITH WAVE TIMING WILL BE PRIMARY PLAYERS IN THE NORTHERN EXTENT OF SEVERE POTENTIAL ALONG WITH THE HIGH TEMP FORECAST. AT ANY RATE...STRONGEST INSTABILITY WILL NEAR THE NEBRASKA BORDER...WHERE CAPE VALUES OF ~1.5-3 KJ/KG ARE EXPECTED. 0-6 KM BULK SHEAR WILL BE QUITE HIGH (~50 KTS) SO SUPERCELL DEVELOPMENT WILL NOT BE A PROBLEM. ALSO...LOW LEVEL SHEAR WILL ALSO BE SUFFICIENT OVER THE FAR SRN CWA TO POSSIBLY SUPPORT A TORNADIC STORM IN THE AFT/EARLY EVE. PRIMARY WAVE WILL MOVE THROUGH IN THE EVENING HOURS...WITH SHOWERS/THUNDERSTORMS CONTINUING OVERNIGHT THOUGH TAPERING TOWARDS EARLY MONDAY MORNING. FOR MONDAY...SLIGHTLY BELOW AVERAGE TEMPS ARE EXPECTED OVER THE AREA IN THE WAKE OF THE AFOREMENTIONED COLD FRONT. TROF AXIS WILL PUSH EAST OF THE AREA...THOUGH WILL KEEP SOME LOW END POPS OVER NWRN SODAK WITH CYCLONIC FLOW ALOFT LINGERING OVER THE AREA. EXTENDED...A SHARP UPPER LEVEL RIDGE OVER THE CENTRAL U.S. WILL RESULT IN DRY HOT CONDITIONS WEDNESDAY AND THURSDAY OF NEXT WEEK. THE NEXT MAJOR WEATHER SYSTEM IS SHOWN ROTATING ACROSS THE NORTHERN PLAINS LATE THURSDAY THROUGH EARLY FRIDAY. WILL KEEP THE SLIGHT CHANCE POPS IN THE GRIDS FOR NOW BUT IF THE MODELS ARE CONSISTENT WITH THAT SYSTEM...THE POPS FOR 00Z THROUGH 12Z FRIDAY WILL NEED TO BE INCREASED. && .AVIATION...VFR CONDITIONS WILL PREVAIL THROUGH THE FORECAST PERIOD. SCATTERED LATE AFTERNOON AND EVENING TSRA WILL DEVELOP...SOME OF WHICH MAY BE SEVERE AND PRODUCE LOCALIZED IFR CIGS/VSBYS. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...NONE.
