AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
338 PM MDT SAT JUN 21 2014
.SHORT TERM...VALID FOR SUN AND MON...
WEATHER PATTERN LOOKS TO BE FAIRLY QUIET OVERALL WITH NO MAJOR
STORM SYSTEM TO IMPACT THE FORECAST AREA DURING THE NEXT COUPLE OF
DAYS. CURRENTLY...A WEAK FRONT HAS MOVED THROUGH THE FORECAST AREA
AS WINDS HAVE SWITCHED TO THE NORTHWEST. A WEAK BOUNDARY WAS
SITUATED ACROSS OUR NORTHWEST COUNTIES WHICH HELPED TO TRIGGER A
COUPLE OF THUNDERSTORMS ACROSS GOLDEN VALLEY AND MUSELLSHELL
COUNTIES EARLIER THIS AFTERNOON. SCATTERED SHOWERS AND
THUNDERSTORMS CONTINUE TO FORM ALONG THIS BOUNDARY WHICH IS SLOWLY
SINKING SOUTHEAST. AT THE SAME TIME...A WEAK UPPER LEVEL
DISTURBANCE OVER EASTERN IDAHO IS HELPING TO KICK OFF SOME
SHOWER/THUNDERSTORM ACTIVITY OVER THE BEARTOOTH/ABSAROKA AND BIG
HORN MOUNTAINS AND ADJACENT FOOTHILLS. WILL CONTINUE WITH SLIGHT
POP CHANCES THROUGH THIS EVENING ACROSS ALL BUT THE FAR NORTHEAST
COUNTIES AS SOUNDINGS SHOW THAT AREA TO BE CAPPED THROUGH THIS
EVENING.
MAINLY SPLIT ZONAL FLOW WILL BE OVER THE FORECAST AREA THROUGH
SUNDAY WITH SOME RIDGING BUILDING IN FOR MONDAY. SOME WEAK
DISTURBANCES WITHIN THE FLOW WILL ALLOW FOR CONTINUED CHANCES FOR
SHOWERS AND THUNDERSTORMS. BEST CHANCES LOOK TO BE OVER THE
BEARTOOTH/ABSAROKA/BIG HORN MOUNTAINS AND ADJACENT FOOTHILLS...AS
WELL AS ALONG THE MONTANA/WYOMING BORDER AS STRONGER DISTURBANCES
MOVE ACROSS WYOMING. HIGHS SUNDAY WILL BE SLIGHTLY COOLER THAN
TODAY AS A RESULT OF THE WEAK FRONT THAT MOVED THROUGH THE AREA.
READINGS MONDAY WILL REBOUND BACK TO NORMAL WITH MIDDLE TO UPPER
70S COMMON. HOOLEY
.LONG TERM...VALID FOR TUE...WED...THU...FRI...SAT...
MINOR ADJUSTMENTS TO THE GOING FORECAST THIS AFTERNOON. OVERALL
MODELS TRENDING TOWARD SEASONAL TEMPERATURES AND ABOVE CLIMO POPS
WEDNESDAY THROUGH THE END OF THE EXTENDED...WITH TUESDAY LOOKING
TO HAVE THE LEAST CHANCE OF PRECIPITATION. DESPITE THE LOWER
CHANCES OF A STORM THERE WILL BE ENOUGH CAPE/SHEAR OVER WESTERN
ZONES TUESDAY FOR A STRONG STORM OR TWO. BEST CHANCE FOR A SEVERE
STORM LOOKS TO BE WEDNESDAY AND THURSDAY AFTERNOON/EVENING FROM
ROSEBUD COUNTY EAST INTO THE DAKOTAS WHERE 40KTS OF SHEAR AND 2000
JOULES OF CAPE ARE PROGGED AHEAD OF SEVERAL DISTURBANCES CROSSING
FROM THE SOUTHWEST. FRIDAY AND SATURDAY SHEAR DIMINISHES BY HALF
ALONG WITH CAPE VALUES AS NORTHWESTERLY FLOW CUTS OFF PLAINS
MOISTURE FEED IN THE LOWER LEVELS. INSTABILITY STILL LOOKS
SUFFICIENT FOR SCATTERED SHOWERS AND THUNDERSTORMS DURING THIS
TIME BUT THREAT OF STRONG TO SEVERE STORMS IS DIMINISHED. MODELS
IN PRETTY GOOD AGREEMENT WITH TEMPERATURES IN THE 75 TO 85 DEGREE
RANGE THROUGH THE EXTENDED PERIOD. CHAMBERS
&&
.AVIATION...
VFR CONDITIONS WILL PREVAIL THIS EVENING...WITH CEILINGS LOWERING
TOWARD MVFR/LOW VFR LEVELS OVERNIGHT. ISOLATED TO SCATTERED
SHOWERS AND THUNDERSTORMS ARE EXPECTED THIS EVENING...MAINLY SOUTH
OF A HARLOWTON TO BILLINGS TO EKALAKA LINE. LOCAL MVFR CONDITIONS
IN HEAVY RAIN CAN BE EXPECTED NEAR THESE STORMS. OVERNIGHT
SCATTERED SHOWERS WILL DEVELOP IN THE VICINITY OF AREA MOUNTAINS
AND SPREAD NORTHEAST INTO THE MORNING HOURS. ALONG WITH LOWER
CEILINGS MVFR VISIBILITIES ARE POSSIBLE NEAR SHOWER ACTIVITY.
