AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GLASGOW MT
905 AM MDT MON JUL 2 2007

.SHORT TERM...FOR NORTHEAST MONTANA...REST OF TODAY...
ONE SHORTWAVE IS SEEN ON SATELLITE PUSHING ACROSS EASTERN MONTANA
THIS MORNING. THERE ARE A COUPLE OF ISOLATED THUNDERSTORMS MOVING
ACROSS THE WESTERN ZONES AS WELL AS GARFIELD COUNTY THIS MORNING.
SOME OF THE CONVECTION HAS BEEN ON THE STRONG SIDE AT TIMES...BUT
REMAINING JUST BELOW SEVERE LIMITS SO FAR. IT LOOKS LIKE THINGS
WILL DRY OUT FOR MOST OF THE CWA THIS AFTERNOON...HOWEVER A STRONG
SHORTWAVE IS EVIDENT ON WATER VAPOR ACROSS CENTRAL OREGON. AS THIS
WAVE LIFTS UP INTO OUR AREA THIS EVENING THE AIRMASS WILL BECOME
EVEN MORE UNSTABLE. THE 12Z KGGW SOUNDING WAS ALREADY VERY
UNSTABLE WITH A LIFTED INDEX OF -8C AND CAPE NEAR 3000 J/KG.
STRONG DAYTIME HEATING WILL CONTINUE TO DESTABILIZE THE ATMOSPHERE
AND MAY SET THE STAGE FOR A FORMIDABLE ROUND OF SEVERE WEATHER
THIS EVENING. INITIALLY STORMS ARE LIKELY TO BE MORE DISCRETE
CELLS WITH THE BIGGEST THREAT LIKELY TO BE LARGE HAIL. SOME
INDICATION THAT THE SYSTEM MAY TRANSITION INTO AN MCS LATER
TONIGHT WITH THE THREAT OF DAMAGING WIND AND LARGE HAIL. OTHER
THAN A FEW TWEAKS TO THE POP GRIDS THIS MORNING THE ONGOING
FORECAST LOOKS TO BE IN GOOD SHAPE. CB

PREVIOUS SHORT TERM...
SW FLOW ALOFT PROVING TO BE A TYPICALLY UNSETTLED
ONE...ESPECIALLY AT THIS PEAK CONVECTIVE TIME OF YEAR. A PARADE OF
SHORTWAVES HAVE BEEN ARRIVING AT LEAST EVERY DAY...EASILY TOUCHING
OFF THUNDERSTORMS OVER MOUNTAINS TO OUR SW...THAT SURVIVE MOVING
ACROSS OUR AREA IN MODERATE TO STRONGLY UNSTABLE AIRMASS
ALOFT...NIGHTTIME HOURS NOT HAVING MUCH WEAKENING EFFECT.

CURRENT SHORTWAVE BEHAVING SIMILARLY...MOVING THRU OUR WEST
EARLY THIS MORN...REQUIRING SEVERAL FINE-TUNES TO POPS. ONLY
SLIGHT WEAKENING OF CONVECTION SHOWN ON 88D RADAR LOOP...AS IT
ENTERS SLIGHTLY LESS UNSTABLE AIRMASS IN OUR N. NOT MUCH AIRMASS
CHANGE TODAY. THOSE AREAS HELD TO LOWER 80S YESTERDAY BY MOSTLY
CLOUDY SKIES...SHOULD JOIN REST OF AREA THAT REACHED AROUND 90
TODAY WITH MORE SUNSHINE. CURRENT SHORTWAVE SHOULD EXIT OUR E BY
NOON ALLOWING AN AFTERNOON BREAK FROM CONVECTION WITH FAIR AMOUNT
OF SUNSHINE. LOW LEVEL WINDS TURNING S-SE HELP WITH WARMING.

A STRONGER SHORTWAVE JUST OFF N CA/S OR COAST WILL ARRIVE THIS
EVENING AND AIRMASS BECOMES MORE UNSTABLE WITH SE LOW LEVEL FLOW
BRINGING INCREASING MOISTURE. CONVECTION FOCUSES ON SURFACE LOW AND
DEVELOPING COOL FRONT THAT MOVE THRU AREA. PREFER TO LEAN
STRONGLY TO THE NAM WHICH HAS QPF OVER AN INCH OVER PART OF OUR
AREA. OTHER MODELS SEEM TOO WEAK OR DRY WITH THIS FOR THE
PATTERN...AND NAM CLEARLY HAS THE MORE REALISTIC DEW POINTS. WE
SEE LIFTED INDEXES ON FORECAST NAM SOUNDINGS DOWN TO -9 AND CAPES
TO 4300 J/KG IN OUR EAST LATE TONIGHT. NO STRONG CAPPING SEEN ON
SOUNDINGS EITHER. 0-6 KM SHEAR GENERALLY 30 KT OR SO. PER SWODY1
EXPECT ANOTHER ROUND OF SEVERE TSTORMS FOR OUR AREA TONIGHT...WITH
SUPERCELLS POSSIBLE AT ANY LOCATION.

THIS MAY BE THE LAST SIGNIFICANT SHORTWAVE FOR AWHILE. ALTHOUGH
NOT MUCH AIRMASS CHANGE THRU THE PERIOD...PREFER SLIGHT COOLING
BEHIND THIS SYSTEM WITH SURFACE WINDS PICKING UP FROM THE N-NW
BEHIND SURFACE LOW TUE. RATHER HIGH 500 MB HEIGHTS WELL INTO 580S
DM AND THICKNESSES IN 570S DM MEAN CONTINUED ABOVE NORMAL TEMPS.
THE UPPER HIGH AND RIDING RETROGRADES A LITTLE WEST THOUGH...PUTTING NE
MT INTO A LITTLE DRIER AND LESS UNSTABLE AIR TUE AND WED.
SIMONSEN

.LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...
GOOD MODEL AGREEMENT THROUGH FRIDAY WITH RIDGE BUILDING OVER THE
HIGH PLAINS. VERY WARM AND DRY UNDER THE RIDGE WITH TEMPERATURES
PUSHING TOWARD 100 ON FRIDAY. MORE UNCERTAINTY FOR THE WEEKEND AS
MODELS INDICATING SHORTWAVE/COLD FRONT SLIDING ACROSS MONTANA TO
FLATTEN OUT THE RIDGE AND COOL TEMPERATURES. GENERAL CONSENSUS OF
THE MODELS IS FOR COLD FRONT PASSAGE ON SATURDAY BUT WITH A DELAY
IN THE INFLUX OF COLDER AIR...MAKING FOR STILL TOASTY WEATHER
SATURDAY.

WITH THE FLATTENING OF THE RIDGE WILL ALSO COME A RETURN TO MORE
ACTIVE SHORTWAVE PATTERN...AND A RELATED INCREASE IN THUNDERSTORM
POTENTIAL. THIS SHOULD LAST THROUGH THE END OF THE FORECAST PERIOD
WHEN THE RIDGE REBOUNDS TO THE WEST. EBERT

&&

.AVIATION...
VFR CONDITIONS WITH LIGHT WINDS ARE EXPECTED MOST OF THE TIME THROUGH
THE NEXT 24 HOURS. ISOLATED TO SCATTERED THUNDERSTORMS WILL MOVE
ACROSS EASTERN MONTANA TODAY AND TONIGHT WHICH MAY BRING BRIEF
PERIODS OF MVFR AND IFR CONDITIONS DUE TO HEAVY RAIN. GFF
