AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
347 PM MDT TUE JUL 10 2012
.SHORT TERM...VALID FOR WED AND THU...
HIGH PRESSURE RIDGING WILL CONTINUE TO HOLD FIRM ACROSS THE
FORECAST AREA FOR THE NEXT COUPLE OF DAYS. MONSOONAL MOISTURE
WILL UNDERCUT THE RIDGE THIS AFTERNOON AND EVENING BRINGING A
CHANCE FOR A THUNDERSTORM ALONG AND WEST OF A SHERIDAN TO
BILLINGS TO ROUNDUP LINE. THUNDERSTORMS WILL BE A MIX OF WET AND
DRY AND MAY PRODUCE WIND GUSTS AROUND 50 MPH. OTHERWISE...EXPECT
A CLEAR TO PARTLY CLOUDY SKY OVERNIGHT. A STRONGER DISTURBANCE
WILL MOVE ACROSS THE ENTIRE FORECAST AREA WEDNESDAY AFTERNOON AND
EVENING. THIS DISTURBANCE WILL FLATTEN THE RIDGE SOMEWHAT
ALLOWING FOR A WEAK COOL FRONT TO MOVE ACROSS THE AREA DURING THE
AFTERNOON. ONLY EFFECT THIS FRONT WILL HAVE IS A LIGHT WIND SHIFT
TO THE NORTHWEST AS TEMPERATURES WILL REMAIN HOT FOR THURSDAY.
THUNDERSTORMS WEDNESDAY WILL BE A MIX OF WET AND DRY WITH STRONG
GUSTY WINDS. THE MAIN THREAT FROM THUNDERSTORMS THIS
AFTERNOON/EVENING AND AGAIN WEDNESDAY AFTERNOON AND EVENING WILL
BE LIGHTNING ACCOMPANIED BY GUSTY THUNDERSTORM WINDS POSING FIRE
CONCERNS. AS A RESULT...WILL CONTINUE THE RED FLAG WARNING
THROUGH MIDNIGHT FROM BILLINGS NORTH AND WEST. IN ADDITION...HAVE
ALSO ISSUED ANOTHER RED FLAG WARNING FOR THE ENTIRE FORECAST AREA
WEDNESDAY AFTERNOON AND EVENING AS ANOTHER CRITICAL FIRE WEATHER
DAY LOOKS LIKELY AS MODELS SHOW LIGHTNING ACTIVITY INCREASING.
THURSDAY IS EXPECTED TO BE LESS ACTIVE WITH JUST A SLIGHT
THUNDERSTORM CHANCE OVER THE MOUNTAINS AND NEAR THE DAKOTA
BORDERS. HOOLEY
.LONG TERM...VALID FOR FRI...SAT...SUN...MON...TUE...
FRIDAY THE RIDGE REBUILDS OVER THE REGION WITH TEMPERATURES AGAIN
CLIMBING INTO THE UPPER 90S. LOOKING AT THUNDERSTORM ACTIVITY TO
PICK UP AGAIN OVER THE WESTERN MOUNTAINS AS LOW ELEVATIONS FEATURE
WEAK EASTERLY FLOW WHICH WILL SUPPORT SOME CAPPING FOR THE PLAINS.
SATURDAY IS SETTING UP TO BE POSSIBLY A BETTER RAINFALL EVENT FOR
THE AREA AS THE LATEST GFS SHOWS A WEAK WAVE STALLING AND ALLOWING
MOISTURE TO DEEPEN OVER SOUTHWEST MONTANA. WHILE THE ECWMF IS NOT
AS PRONOUNCED ABOUT THIS FEATURE IT DOES SHOW A WAVE MOVING ACROSS
SOUTHERN MONTANA DURING THIS PERIOD. EITHER WAY...IT APPEARS THAT
THE LOW LEVEL EASTERLY FLOW CONTINUES AND ALLOWS MOISTURE TO
DEEPEN OVER THE AREA SUPPORTING A BETTER CHANCE FOR PRECIPITATION.
HAVE RAISED POPS FRO THE MOUNTAINS AND FOOTHILLS AREAS BUT WOULD
LIKE TO SEE AN ADDITIONAL MODEL RUN TO HAVE CONFIDENCE TO GO
LIKELY. ALONG WITH THE PRECIPITATION WOULD EXPECT A CLOUDIER AND
COOLER DAY.
THE PERIOD SUNDAY THROUGH TUESDAY IS STARTING TO LOOK NOT HAS HOT
AS BOTH MODELS SUPPRESS RIDGING BUT MODELS ACHIEVE THIS IN
DIFFERENT WAYS. ECMWF HAS A STRONGER NORTHERN BRANCH OF ENERGY
OVER SOUTHERN CANADA WHICH KEEPS THE RIDGE FROM REBOUNDING WITH
WEAK PULSES OF ENERGY FILTERING ACROSS THE NORTHERN ROCKIES. NEW
GFS KEEPS A MORE DYNAMIC SOUTHWESTERLY FLOW OVER THE AREA AS IT
CUTS OFF A LOW OVER THE PACIFIC NORTHWEST. DEFINITELY LOOKS TO BE
NOT AS INTENSELY HOT DURING THIS PERIOD AND HOW MUCH BENEFICIAL
RAIN FALLS REMAINS TO BE SEEN. BORSUM
&&
.AVIATION...
ISOLATED TO SCATTERED HIGH-BASED THUNDERSTORM ACTIVITY CAN BE
EXPECTED LATE THIS AFTERNOON AND EVENING FROM KMLS-KSHR WESTWARD.
GUSTY AND ERRATIC WINDS WILL OCCUR NEAR THESE STORMS...OTHERWISE
VFR CONDITIONS WILL PREVAIL. MORE THUNDERSTORMS ARE EXPECTED
WEDNESDAY AFTERNOON AND EVENING...EXTENDING EAST TO THE DAKOTAS
BORDER. GUSTY SURFACE WINDS WILL AGAIN BE THE GREATEST THREAT WITH
THE ACTIVITY ON WEDNESDAY. JKL
