AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
317 PM MDT MON JUN 25 2012
.SHORT TERM...VALID FOR TUE AND WED...
HIGH AMPLITUDE UPPER RIDGE AXIS HAD SHIFTED INTO THE DAKOTAS THIS
AFTERNOON PER WATER VAPOR IMAGERY...AND UPPER SW FLOW WAS OVER THE
REGION. GIVEN WAVES MOVING THROUGH THE FLOW...AND DIFFERENCES IN
WHERE THE MODELS PREDICT THE LOCATION OF THE SURFACE LOW...HAVE
EXPANDED POPS FURTHER W THIS EVENING. ALSO INCREASED THEM TO CHANCE
OVER THE E WHERE CONVECTION HAS BEEN DEVELOPING THIS AFTERNOON.
CONVECTION HAD ALSO DEVELOPED IN E WY. WILL KEEP DRY
THUNDERSTORMS IN THE FAR WESTERN ZONES DUE TO LOW PRECIPITABLE
WATERS. SOME OF THE THUNDERSTORMS MAY BE SEVERE OVER THE CENTRAL
AND EASTERN ZONES AS CONVECTION HAS BEEN BREAKING THE CAP IN SE WY
AND SEVERAL THOUSAND JOULES OF CAPE WERE AVAILABLE ABOVE THE CAP
INTO E MT. A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED FOR THIS AREA
THROUGH 05Z. TRIMMED BACK WESTWARD EXTENT OF POPS AFTER 06Z AS
WAVES WILL BE ALMOST OUT OF THE AREA. WARMED UP THE CENTRAL AND E
AS 850 MB TEMPERATURES WILL BE CLOSE TO +30 DEGREES C.
ON TUE...THE PACIFIC UPPER LOW...SEEN ON WATER VAPOR IMAGERY NEAR
THE OR COAST THIS AFTERNOON...WILL PUSH A COLD FRONT INTO THE AREA
IN THE AFTERNOON. AHEAD OF THE FRONT...SOUNDINGS SHOWED GUSTY SW
WINDS IN THE 30 TO 40 KT RANGE WITH HIGHER VALUES IN KLVM. THE FRONT
WILL PUSH THE STRONG 850 MB THERMAL RIDGE E AND USHER IN GUSTY W
WINDS IN THE AFTERNOON. SOUNDINGS SHOWED HIGH-LEVEL MOISTURE
CONFINED TO THE EASTERN ZONES IN THE AFTERNOON...SO TRIMMED BACK
POPS TO REFLECT THIS SCENARIO. TEMPERATURES WERE IN GOOD SHAPE WITH
NEAR RECORD HIGHS EXPECTED IN KMLS. A NW WIND SURGE WILL ACCOMPANY
THE FRONT TUE EVENING WITH CONTINUED COLD ADVECTION. THE COMBINATION
OF HOT...DRY AND WINDY CONDITIONS WITH A FRONTAL PASSAGE HAS
PROMPTED THE ISSUANCE OF A RED FLAG WARNING ACROSS MOST OF THE AREA
LATE TUE MORNING THROUGH 06Z WED. SOUNDINGS WERE DRY TUE NIGHT
SO WILL CONTINUE THE DRY FORECAST. LOWERED TEMPERATURES BASED ON
FORECAST 850 MB TEMPERATURES.
THERE WILL BE SOME TRAILING VORTICITY MOVING THROUGH THE AREA ON WED
AS THE UPPER LOW MOVES INTO CANADA. THE AIRMASS...HOWEVER...WILL BE
VERY DRY. LOWERED TEMPERATURES IN THE FAR E BASED ON MIXING
PROFILES. ZONAL FLOW WILL BE OVER THE AREA WED NIGHT WITH CONTINUED
DRY WEATHER. WED NIGHT MINS WERE IN GOOD SHAPE. ARTHUR
.LONG TERM...VALID FOR THU...FRI...SAT...SUN...MON...
MODELS ARE IN FAIRLY GOOD AGREEMENT THURSDAY THROUGH FRIDAY WITH
THE LONG WAVE PATTERN OVER OUR REGION SUGGESTING A ZONAL/LOW
AMPLITUDE RIDGE. BOTH MODELS HINT AT SOME MINOR RIPPLES IN THE
MEAN FLOW SUGGESTING SOME WEAK SHORT WAVE ENERGY...BUT THE IMPACT
SEEMS TO BE MAINLY AFFECT AREAS TO OUR NORTH AND WEST. A BROAD
SPLIT FLOW LIKE PATTERN OFF THE WEST COAST MAY EVENTUALLY WORK
INLAND AND BRING A CHANCE OF PRECIPITATION BY NEXT WEEKEND. MODELS
DIVERGE A BIT ON THE STRENGTH OF THE THERMAL RIDGE OVER THE AREA
THIS WEEKEND WITH THE ECMWF A BIT MORE AGGRESSIVE. IF THE RIDGE
OVER US AMPLIFIES MORE THAN THE AVERAGE 500MB PROG CURRENTLY
INDICATES WE COULD SEE HIGHS WELL INTO THE 90S AGAIN THIS WEEKEND.
OVERALL...THE INHERITED EXTENDED WAS IN GOOD SHAPE. JUST MADE SOME
MINOR UPDATES FOR THIS EXTENDED PACKAGE TWEAKING HIGHS FRIDAY
THROUGH SUNDAY AND A FEW RH GRIDS. BT
&&
.AVIATION...
ISOLATED TO WIDELY SCATTERED THUNDERSTORM ACTIVITY IS POSSIBLE
EAST OF A KMLS TO KSHR LINE THIS EVENING. ONE OR TWO OF THESE
COULD BE STRONG WITH HAIL AND STRONG SURFACE WINDS. THERE IS A
SLIGHT CHANCE OF SHOWERS AND ISOLATED THUNDERSTORMS WEST OF THIS
LINE AS WELL...BUT ANY ACTIVITY THAT FORMS WILL BE HIGH BASED WITH
MOSTLY VIRGA. VFR CONDITIONS WILL OTHERWISE PREVAIL. BT
