AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
153 PM MDT THU JUL 1 2010

.SHORT TERM...VALID FOR TDY AND FRI...

A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED FOR MUCH OF THE CWA.
MODERATELY-HIGH INSTABILITY WILL GENERATE SCATTERED THUNDERSTORMS
ACROSS MUCH OF THE CWA. MODERATE DEEP-LAYER SHEAR WILL ALLOW
STORMS TO ORGANIZE. THE PRIMARY THREAT WILL BE LARGE HAIL. IF
STORMS CONGREGATE...DAMAGING WIND GUSTS WILL BECOME A THREAT. AN
ISOLATED TORNADO CANNOT BE RULED OUT GIVEN SUPERCELL FORMATION.
HOWEVER...A NUMBER OF TORNADIC PARAMETERS APPEAR MINIMAL FOR
TODAY. BRS

.PREVIOUS DISCUSSION...
A LINE OF SHOWERS AND THUNDERSTORMS HAS SET UP THIS MORNING FROM
NORTHERN ROSEBUD COUNTY SOUTHWEST TO THE BEARTOOTH FOOTHILLS.
THUNDERSTORMS HAVE TAPPED ELEVATED INSTABILITY GENERALLY AROUND
500 J/KG. EXPECT BRIEF HEAVY RAIN AND FREQUENT LIGHTNING WITH
THESE STORMS. PRECIPITATION WILL TRACK NORTHEAST THROUGH LATE
MORNING. SCATTERED THUNDERSTORMS ARE EXPECTED FOR THIS AFTERNOON
THROUGH TONIGHT. SOME OF THESE STORMS COULD BECOME SEVERE. 12Z
NAM DEPICTS AROUND 2000 J/KG OF MLCAPE THIS AFTERNOON. 45-50 KTS
OF BULK SHEAR WILL ALLOW STORMS TO ORGANIZE. LARGE HAIL AND
STRONG WINDS WILL BE THE PRIMARY THREATS TODAY. STORMS WILL ABLE
TO PRODUCE VERY HEAVY RAIN GIVEN PWATS AROUND ONE INCH. AN
ISOLATED TORNADO CANNOT BE RULED OUT AS STORMS BECOME ORGANIZED.
HOWEVER...LOW-LEVEL SHEAR/HELICITY ARE EXPECTED TO BE MINIMAL.
LCLS ARE SOMEWHAT HIGH AND RANGE FROM 1500-2000 M. CONVECTION
SHOULD INITIATE OVER THE SOUTHWESTERN MOUNTAINS BY EARLY AFTERNOON
AS A SHORTWAVE APPROACHES THE CWA. CONVECTIVE INHIBITION IS
LARGELY GONE BY 2100Z SO WOULD EXPECT SCATTERED COVERAGE BY MID-
AFTERNOON. BRS

.LONG TERM...VALID FOR SAT...SUN...MON...TUE...WED...

DID NOT MAKE ANY CHANGES TO THE EXTENDED FORECAST THIS AFTERNOON.
MODELS IN PRETTY GOOD AGREEMENT IN KEEPING SOME SORT OF TROUGH
FEATURE OVER THE REGION THROUGH MONDAY NIGHT KEEPING
TEMPERATURES COOLER THAN NORMAL FOR THIS TIME OF YEAR. THE
PRECIPITATION CHANCES DO NOT LOOK THAT GREAT AT THIS TIME AND
WILL MAINLY BE A COOLER TEMPERATURE EFFECT. DIFFERENCES SHOW UP
FROM TUESDAY AND BEYOND IN THE MODELS. THE GFS BUILDS IN A RIDGE
THROUGH THAT PERIOD WHERE THE ECMWF KEEPS THINGS MORE ZONAL AND
MORE UNSETTLED. SO HAVE KEPT THINGS FROM THE PREVIOUS FORECAST
GOING WITH TEMPS AROUND NORMAL FOR THE MOST PART AND FAIRLY DRY
UNTIL THINGS BECOME A BIT CLEARER. SOLUM

&&

.AVIATION...

SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE
EVENING. STRONG TO SEVERE THUNDERSTORMS WILL AGAIN BE POSSIBLE
WITH LARGE HAIL AND DAMAGING WINDS THE MAIN THREATS. VFR
CONDITIONS WILL PREVAIL. HOWEVER...EXPECT MVFR TO IFR CONDITIONS
IN AND NEAR ANY THUNDERSTORM. THE MOUNTAINS WILL BE OBSCURED AT
TIMES. SOLUM
