The episode as NWS BYZ wrote it up.
A couple of isolated thunderstorms produced severe wind gusts during the late afternoon hours on the 2nd.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Billings, MT wrote its last area forecast discussion before the first event at Jun 2, 1:22 PM MST, 1 hour 23 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
222 PM MDT SAT JUN 2 2012
.SHORT TERM...VALID FOR SUN AND MON...
THE FORECAST NOW INCLUDES A SEVERE THUNDERSTORM WATCH UNTIL 03 UTC
FOR ALL OF SOUTH CENTRAL AND SOUTHEASTERN MT. SCATTERED STORMS ARE
ON TRACK TO POSE A SEVERE THREAT THE NEXT SEVERAL HOURS. SCHULTZ
PREVIOUS DISCUSSION...ISSUED AT 125 PM MDT SAT JUN 2 2012...
THE POTENTIAL FOR SEVERE WIND OR HAIL THROUGH THIS EVENING REMAINS
THE FOCUS OF THE SHORT TERM. WE ALLOWED CONTINUITY TO RULE MUCH OF
THE SUN AND MON FORECAST...ESPECIALLY SINCE UNCERTAINTY GROWS WITH
REGARD TO STORM CHANCES ON MON.
FOR THE REST OF THIS AFTERNOON AND EVENING...SCATTERED STORMS WILL
AFFECT THE AREA...AND WE HAVE INCLUDED A SEVERE MENTION WITHIN THE
GRIDDED FORECAST EVERYWHERE GIVEN EFFECTIVE BULK SHEAR OF 30 TO 40
KT...MLCAPE OF 500 T0 1000 J/KG WITH STEEP 700-500 HPA LAPSE RATES
AROUND 8 DEG C/KM...AND INVERTED V-SOUNDING PROFILES. WIND WILL BE
THE MAIN THREAT...BUT MARGINALLY SEVERE HAIL IS POSSIBLE TOO. SOME
INITIAL CONVECTION IS MOVING THROUGH SOUTH CENTRAL MT AS OF 19 UTC
AND THAT ACTIVITY COULD STRENGTHEN...OR JUST BECOME MORE EFFECTIVE
AT PRODUCING STRONG WINDS...AS IT MOVES INTO THE DESTABILIZING AIR
MASS FROM SHERIDAN WY UP INTO SOUTHEASTERN MT. MEANWHILE...WE HAVE
HAD A SOLID AREA OF CLEARING BEHIND THE CLOUDS ASSOCIATED WITH THE
INITIAL CONVECTION...SO NEAR-TERM MODEL SOLUTIONS LOOK ON TRACK IN
SHOWING MLCAPE INCREASING QUICKLY THIS AFTERNOON. THE STORMS CLOSE
TO DILLON MT AT 19 UTC WILL BE TRACKING INTO THIS AIR MASS...AND A
SIMPLE EXTRAPOLATION TAKES THAT ACTIVITY INTO LIVINGSTON AROUND 21
UTC AND BILLINGS NEAR 23 UTC. THAT LINES UP WELL WITH COLD FRONTAL
TIMING SHOWN BY MOST MODELS...INCLUDING THE 18 UTC RAP AND 15 UTC
HRRR...WITH PASSAGE AT BILLINGS ADVERTISED AROUND 00 UTC. LOOK FOR
MOST OF THE ACTIVITY TO SETTLE DOWN BY ABOUT 03 UTC...WITH A QUIET
PERIOD FOR MOST OF THE AREA OVERNIGHT.
SUN...A SURFACE HIGH PRESSURE RIDGE WILL SLIDE FROM EASTERN MT AND
INTO THE WESTERN DAKOTAS BENEATH A NEBULOUS WEST-SOUTHWEST 500-HPA
FLOW. LOW-LEVEL EASTERLY FLOW AND 500 J/KG OF MLCAPE COULD SUPPORT
SOME AFTERNOON AND EVENING STORMS IN AND NEAR THE HIGH TERRAIN. WE
CHOSE TO KEEP EVEN LOW CHANCES OF CONVECTION OUT OF BILLINGS UNTIL
AFTER 00 UTC THOUGH BECAUSE FORECAST SOUNDINGS SHOW MINIMAL MLCAPE
AND MODEST CAPPING OVER THAT AREA DURING THE DAY. WE ARE SHOWING A
SLIGHT CHANCE OF STORMS OVER THE PLAINS OF SOUTH CENTRAL MT ON SUN
NIGHT...BUT ONLY A WEAK LOW-LEVEL JET IS SHOWN BY THE LAST SEVERAL
MODEL SIMULATIONS. THUS...THE CONVECTION MAY END UP BEING REMNANTS
OF THE STUFF THAT COMES OFF THE HIGH TERRAIN...RATHER THAN ANY NEW
DEVELOPMENT. THAT MAY RESULT IN MINIMAL COVERAGE AFTER 06 UTC.
MON...LOW-LEVEL SOUTHEAST FLOW IS EXPECTED TO INCREASE AS PRESSURE
FALLS COMMENCE OVER THE REGION. THE 12 UTC NAM /AND MOST PAST RUNS
OF THAT MODEL/ SIMULATES DEEP CONVECTION IN THE LATE AFTERNOON AND
EVENING ON THE PLAINS BETWEEN ABOUT BILLINGS AND MILES CITY AS THE
BOUNDARY LAYER MOISTENS ON THOSE SOUTHEAST WINDS. THAT SCENARIO IS
NOT OUT OF THE QUESTION SINCE THE AREA COULD BE ON THE EDGE OF THE
MID-LEVEL CAP...WITH 700-HPA TEMPERATURES ONLY AROUND 12 C. WE ARE
NOT SURE THAT THERE WILL ACTUALLY BE FORCING TO DEVELOP STORMS OUT
ON THE EDGE OF THE CAP THOUGH...WITH THE 12 UTC GFS KEEPING HEIGHT
FALLS OF ANY SIGNIFICANCE AT 500 HPA TO THE WEST OF BILLINGS. THAT
LINES UP WITH THE CALIBRATED THUNDERSTORM PROBABILITIES OFF OF THE
09 UTC SREF...WHICH ARE 40 PERCENT AT LIVINGSTON AND 10 PERCENT AT
MILES CITY ON MON. THUS...WE KEPT THE MON AFTERNOON PERIOD DRY FOR
SOUTHEASTERN MT...AND THEN ADVERTISED LOW POPS EVERYWHERE COME MON
EVENING. THERE WILL BE SOME SEVERE RISK IF STORMS FORM. NOTE IT IS
GOING TO BE DOWNRIGHT HOT ON MON TOO...WITH HIGHS AROUND 90 F OVER
MOST OF THE PLAINS AS WARM AIR ADVECTION REVS UP. SCHULTZ
.LONG TERM...VALID FOR TUE...WED...THU...FRI...SAT...
12Z MEDIUM AND LONG RANGE MODELS REMAINED IN FAIR AGREEMENT WITH
THE UPPER TROUGH PROGGED TO MOVE INTO THE AREA ON TUESDAY. MODELS
STILL DEPICTING SOME MINOR DIFFERENCE BUT OVERALL ARE REMAINING
FAIRLY CONSISTENT.
LONG WAVE TROUGH MOVING OVER THE PACIFIC NORTHWEST STATES ON
TUESDAY WITH THE SYSTEM BECOMING NEGATIVELY TILTED. THIS WILL
ALLOW A RIDGE OF HIGH PRESSURE AND THERMAL RIDGE TO AMPLY OVER
THE FORECAST AREA. THIS WILL BRING A VERY WARM DAY TO THE THE
REGION WITH AFTERNOON READINGS IN THE LOW TO MID 90S. AS THE
UPPER TROUGH APPROACHES THE AREA TUESDAY...A STRONG LOW LEVEL JET
WILL DEVELOP AND ADVECT LOW LEVEL MOISTURE INTO THE AREA. MODELS
HAVE BEEN VERY CONSISTENT THE PAST SEVERAL DAYS IN BRINGING IN
VERY DRY AIR ALOFT FOR TUESDAY AND TUESDAY NIGHT. EVEN WITH VERY
DRY AIR ALOFT...SOME ENERGY WILL BE EJECTING OUT OF THE UPPER
TROUGH AND ACROSS OUR AREA. WILL CONTINUE CHANCE THUNDERSTORMS
FOR TUESDAY AND TUESDAY NIGHT EVEN THOUGH MODELS BRING IN DRY AIR
ALOFT. SHOULD CONTINUE TO SEE LOW LEVELS DESTABILIZE WITH HEATING
AND LIFT FROM UPPER ENERGY. UPPER TROUGH SHIFTING EASTWARD ON
WEDNESDAY WHICH WILL PUSH A STRONG COLD FRONT THROUGH THE AREA.
TIMING OF THE FRONT WITH THIS MODEL RUN WILL PUT IT OVER
SOUTHEAST MONTANA BY LATE AFTERNOON AND THIS AREA WILL HAVE THE
BETTER CHANCE OF POSSIBLE STRONG THUNDERSTORMS. UNSETTLED WEATHER
PATTERN TO CONTINUE THURSDAY THROUGH SATURDAY AS A BROAD CYCLONIC
FLOW WILL SET UP. THIS WILL BRING NEAR SEASON TEMPERATURES TO THE
AREA WITH LOWER HEIGHTS ACROSS THE REGION. RICHMOND
&&
.AVIATION...
A SURFACE COLD FRONT OVER WESTERN MONTANA WILL PUSH INTO THE KLVM
AREA LATE THIS AFTERNOON AND INTO SOUTHEAST MONTANA THIS EVENING.
SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG THE FRONT WITH A FEW
THUNDERSTORMS BECOMING SEVERE. THE MAIN THREAT FROM THESE STORMS
WILL BE STRONG WIND GUSTS IN EXCESS OF 55KTS AND 1 INCH HAIL. THE
STRONGER THUNDERSTORMS WILL CREATE AREAS OF MVFR/IFR CONDITIONS
DUE TO HEAVY RAIN LOWERING VISIBILITY AND CEILINGS. PRECIPITATION
WILL BRING WIDESPREAD MOUNTAIN OBSCURATION THIS EVENING.
CONDITIONS WILL IMPROVE BY LATE THIS EVENING WITH VFR CONDITIONS
PREVAILING OVER ALL FLIGHT TERMINALS. RICHMOND
