SOUTH CENTRAL AND SOUTHEAST MONTANA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
201 PM MDT FRI JUL 4 2003
.SHORT TERM...VALID FOR SAT AND SUN...
SHORTWAVE THAT BROUGHT SHOWERS AND THUNDERSTORMS TO THE WESTERN ZONES
THIS MORNING IS MOVING A LITTLE FASTER THAN EXPECTED AND IS PRODUCING
THUNDERSTORMS ACROSS THE SOUTHEAST ZONES ALREADY. LOOKS LIKE IT WILL
EXIT THE CWA BY ISSUANCE TIME SO HAVE REMOVED ALL POPS FOR TONIGHT.
FOR FIREWORKS TONIGHT...WINDS SHOULD DIMINISH BY 900 PM AND SKIES
SHOULD BE MOSTLY CLEAR FOR PERFECT VIEWING CONDITIONS. TEMPERATURES
SHOULD FALL INTO THE LOWER 50S GIVEN DEWPOINTS IN THE 30S TONIGHT. FOR
SATURDAY...MORNING SHOULD BE VERY NICE WITH LIGHT WINDS AND MOSTLY
SUNNY CONDITIONS...BY AFTERNOON THE WINDS WILL PICK UP OUT OF THE WEST
AHEAD OF FAIRLY STRONG COLD FRONT AND ASSOCIATED UPPER TROF. WITH
PREFRONTAL COMPRESSIONAL WARMING WILL GO WITH UPPER 80S IN THE EAST
AND MID 80S WEST...WOULDNT BE SURPRISED BY TEMPERATURES A FEW
DEGREES LOWER THOUGH CONSIDERING TEMPERATURES AND HEIGHTS ALOFT DONT
CHANGE MUCH OVER TODAY...AND MIXING WILL ALLOW SOME OF THIS AIR DOWN TO
THE SURFACE. MODELS ALL INDICATE FRONT MOVING THROUGH BY 900 PM
SATURDAY EVENING...DROPPING TEMPS PRETTY RAPIDLY INTO THE 50S BEHIND
THIS FEATURE. NOT CONVINCED THAT COOL AIR WILL ARRIVE THAT FAST...
THINK MORE LIKELY IT WILL BE HELD UP SEVERAL HOURS AFTER WIND SHIFT.
HOWEVER WITH SURFACE CONVERGENCE WILL GO WITH CHANCE POPS EVERYWHERE
FROM MIDNIGHT ON. UPPER DYNAMICS HOLD BACK UNTIL LATER SUNDAY MORNING...
SO WILL TREND POPS WITH THIS FEATURE AS IT MOVES ACROSS THE REGION
DURING THE DAY SUNDAY. TEMPERATURES LOOK TO BE A GOOD 10 DEGREES COOLER
THAN SATURDAY WITH POTENTIALLY COLDER CONDITIONS IF GUIDANCE NUMBERS ARE
REALIZED. FOR NOW WILL DROP TEMPS INTO THE UPPER 70S AND LOWER 80S AND
REEVALUATE SITUATION AS AIRMASS MOVES INTO SOUTHERN CANADA.
PRECIPITATION WILL COME TO AN END BY LATE AFTERNOON SUNDAY FOR ALL BUT
SOUTHEAST MONTANA. SUNDAY NIGHT LOOKS VERY PLEASANT WITH LIGHT EASTERLY
WINDS...CLEARING SKIES...AND LOW TEMPERATURES IN THE UPPER 40S AND
LOWER 50S. CHAMBERS
.LONG TERM...VALID FOR MON...TUE...WED...THU...FRI...
MONDAY AND TUESDAY...
MEDIUM RANGE FORECAST MODELS CONTINUE TO BE IN AGREEMENT BRINGING NEARLY
ZONAL UPPER LEVEL FLOW ACROSS MONTANA AHEAD OF A LONGWAVE TROUGH MOVING
DOWN THE COAST OF BRITISH COLUMBIA THROUGH EARLY NEXT WEEK. ZONAL FLOW
ALOFT COMBINED WITH SURFACE HIGH PRESSURE BEHIND THE FRONTAL PASSAGE ON
SUNDAY WILL KEEP PRECIPITATION OUT OF THE FORECAST UNTIL MONDAY
AFTERNOON. BY MONDAY AFTERNOON...INSTABILITY WILL INCREASE AS AN UPPER
DISTURBANCE MOVES INTO NORTHWEST WYOMING. HAVE ADDED ISOLATED
THUNDERSTORMS IN THE EXTREME SOUTHWEST ZONES FOR MONDAY AFTERNOON.
MONDAY EVENING AND DURING THE DAY TUESDAY...THE SURFACE LOW RESULTING
FROM THE UPPER DISTURBANCE WILL MOVE EAST AND BRING A CHANCE OF
THUNDERSTORMS TO SHERIDAN COUNTY WYOMING AND THE SOUTHEAST ZONES. THE
LATEST GFS RUN FOR TUESDAY NIGHT CONTINUES TO INDICATE THE UPPER
DISTURBANCE WILL EXIT THE SOUTHEAST ZONES BY TUESDAY EVENING. THUS WILL
REMOVE THE CHANCE OF THUNDERSTORMS IN THE EAST...BUT WILL INTRODUCE THE
CHANCE OF THUNDERSTORMS TUESDAY AFTERNOON AND EVENING ACROSS THE
SOUTHWEST ZONES AS A COMBINATION OF INGREDIENTS MOVES INTO THE FORECAST
AREA. THE FEATURES AFFECTING THE AREA INCLUDE A JET STREAK MOVING ACROSS
THE WYOMING-MONTANA BORDER...AN UPPER LEVEL DISTURBANCE OVER SOUTHERN
IDAHO AND WEST-CENTRAL WYOMING...AND RESULTING MID LEVEL LAPSE RATES
APPROACHING 9 DEGREES C/KM. CARPENTER
WEDNESDAY THROUGH FRIDAY...
MODELS DIFFER FOR THE REMAINDER OF THE WEEK AS THE ECMWF BRINGS A RETURN
TO SOUTHWEST FLOW ALOFT WHILE THE GFS KEEPS THE AREA MORE UNDER THE
INFLUENCE OF HIGH PRESSURE DOWN IN THE FOUR CORNERS REGION. BELIEVE
CONDITIONS SHOULD REMAIN DRY WITH TEMPERATURES SEVERAL DEGREES ABOVE
NORMAL. 700MB AND 850MB TEMPERATURES WILL BE QUITE WARM BY MID TO LATE
WEEK SO READINGS MAY ACTUALLY BE HIGHER THAN CURRENT GRIDS INDICATE.
HOWEVER...WILL NOT TWEAK TEMPERATURES THAT MUCH THIS FAR OUT IN THE
EXTENDED. HOOLEY
SAT SUN MON TUE WED THU FRI
