AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1145 AM MDT MON JUN 25 2012

UPDATED AVIATION SECTION

.UPDATE...VERY INTERESTING AND VARIED WEATHER PATTERN WILL
CONTINUE ACROSS MY FORECAST AREA TODAY. IN THE SOUTH CONDITIONS
ARE VERY DRY...HOT AND WINDY AND RED FLAG WARNINGS WILL REMAIN IN
PLACE THROUGH THIS EVENING. IN THE NORTH LOW CLOUDS AND PATCHY FOG
HAVE FORMED ONCE AGAIN AND WILL STRONGLY INFLUENCE TEMPERATURES
AND STABILITY TODAY. HAVE TWEAKED TEMPERATURES DOWN SEVERAL
DEGREES IN AREAS WHERE CLOUDS ARE EXPECTED TO PERSIST INTO THE
AFTERNOON. MODELS CONTINUE TO SHOW THAT THESE CLOUDS WILL BURN OFF
AND THE AIRMASS WILL BECOME QUITE UNSTABLE THIS AFTERNOON AND
EVENING...ESPECIALLY IN MY FAR NORTHEAST ZONES. UNFORTUNATELY IT
IS NOT AT ALL CERTAIN THAT CONVECTION WILL BE ABLE TO GET STARTED
GIVEN THE LOW LEVEL COOL LAYER AND CAPPING. IF ANY STORMS CAN GET
STARTED...GIVEN THE LARGE AMOUNT OF POTENTIAL CAPE AND FAVORABLE
SHEAR PROFILES...IT APPEARS LIKELY THAT THE STORM COULD GO SEVERE.
FOR NOW HAVE OPTED TO COVER THE POTENTIAL BY TWEAKING POPS UP OVER
MY EASTERN ZONES AND HAVE ADDED AN ISOLATED MENTION OF SEVERE
STORMS FOR THIS EVENING. MPJ

&&

.AVIATION...
UPDATED 1745Z.
CONDITIONS WILL CONTINUE TO VARY ACROSS THE TAF AREA TODAY. DRY
SOUTHWESTERLY FLOW WAS RESULTING IN CLEAR SKIES FOR SOUTHWEST AND
PORTIONS OF CENTRAL MONTANA...INCLUDING KBZN AND KHLN. ACROSS NORTH
CENTRAL MONTANA A MOIST EASTERLY FLOW WAS RESULTING IN LOW CLOUDS
AND MVFR CONDITIONS AT TIMES...AFFECTING KCTB...KGTF...AND KLWT.
CONDITIONS SHOULD IMPROVE TO VFR THIS AFTERNOON AS THE LOW CLOUDS
DISSIPATE...HOWEVER AREAS ALONG THE ROCKY MOUNTAIN FRONT INCLUDING
KCTB COULD SEE MVFR CONDITIONS LINGER WHERE CLOUDS WILL BE SLOWEST
TO DISSIPATE. A FEW ISOLATED THUNDERSTORMS COULD FORM OVER NORTH
CENTRAL MONTANA THIS AFTERNOON...SOME CONTAINING LARGE HAIL AND
STRONG WINDS. THE MOST LIKELY SITES TO SEE A STORM ARE KHVR AND KCTB
LATE IN THE DAY DURING THE LATE AFTERNOON AND EARLY EVENING. A COLD
FRONT WILL APPROACH THE AREA LATE TONIGHT SPREADING SHOWERS AND A
FEW THUNDERSTORMS INTO THE ROCKY MOUNTAIN FRONT...REACHING KCTB
TUESDAY MORNING. LANGLIEB

&&

.FIRE WEATHER...
RED FLAG WARNINGS HAVE BEEN ISSUED FOR MONDAY AFTERNOON AND EVENING
FOR ZONES 110...111 AND 118 FOR STRONG WINDS AND LOW RELATIVE
HUMIDITIES. AFTER DISCUSSIONS WITH FOREST SERVICE HAVE DETERMINED
THAT FUELS IN ZONE 117 REMAIN GREEN ENOUGH THAT WE WILL NOT ISSUE
ANY HIGHLIGHTS FOR THIS ZONE AT THIS TIME. MPJ/SUK

&&

.PREV DISCUSSION...
/ISSUED 529 AM MDT MON JUN 25 2012/
MONDAY TROUGH WEDNESDAY...LARGE SCALE WEATHER PATTERN THAT HAS
BEEN PRESENT SINCE THE MIDDLE OF LAST WEEK WILL REMAIN IN PLACE
FOR ANOTHER 24 HOURS BEFORE FINALLY MOVING EASTWARD. WARM AND
RELATIVELY MOIST CONDITIONS FOR CENTRAL MONTANA WILL OCCUR AGAIN
THIS AFTERNOON. WITH WARM AND DRY CONDITIONS FOR MUCH OF SOUTHWEST
MONTANA. THE LITTLE BELT MOUNTAINS WILL CONTINUE TO WORK AS A
ROUGH BREAK BETWEEN THE TWO AIR MASSES. WITH THESE SEASONABLY WARM
TEMPERATURES A RED FLAG WATCH HAS BEEN ISSUED FOR FIRE WEATHER
ZONES 110...111...AND 118 DUE TO LOW HUMIDITIES AND GUSTY WINDS.
FIRE WEATHER ZONE 117 COULD BECOME CLOSE TO RED FLAG CRITERIA AS
WELL AND WILL BE CLOSELY MONITORED AS DAY PROGRESSES. NORTH
CENTRAL AND CENTRAL MONTANA WILL AGAIN SEE A DECENT POTENTIAL FOR
CONVECTION DUE TO CAPE VALUES THAT WOULD NORMALLY RESULT IN A
MASSIVE THUNDERSTORM OUTBREAK. HOWEVER LOW LEVEL CONVECTIVE
INHIBITION VALUES ARE AGAIN STRONG ENOUGH TO LIMIT ANY CONVECTIVE
GROWTH THAT COULD TAKE ADVANTAGE OF THE UPPER LEVEL ENERGY. IF ANY
STORM DOES BREAK THROUGH THE CAP OF INHIBITION SIGNIFICANT STORM
GROWTH COULD OCCUR VERY QUICKLY. BY TUESDAY THE LARGE SCALE LOW
PRESSURE SYSTEM OFF THE OREGON COAST QUICKLY TRACKS ACROSS CENTRAL
IDAHO AND WILL IMPACT EAST OF THE CONTINENTAL DIVIDE BY TUESDAY
EVENING. PRECIPITATION AMOUNTS ASSOCIATED WITH THIS SYSTEM COULD
BE SIGNIFICANT ESPECIALLY ALONG THE NORTHERN STRETCHES OF THE
ROCKY MOUNTAIN FRONT. THE IMPULSES OF SHORTWAVE TROUGHS THAT
FOLLOW IN THE WAKE OF THE TUESDAY SYSTEM WILL BRING ANOTHER ROUND
OF CONVECTION THROUGH THE AREA WEDNESDAY AS WELL ALONG WITH COOLER
TEMPERATURES AND A MORE ZONAL FLOW PATTERN. HAVE LIMITED THE
AMOUNTS OF QPF WITH THESE SYSTEMS DUE TO THE LACK OF MOISTURE
ASSOCIATED WITH THIS PATTERN. SUK

WEDNESDAY NIGHT THROUGH MONDAY...THE ZONES WILL BE UNDERNEATH
UNSETTLED SOUTHWEST FLOW ALOFT WEDNESDAY NIGHT. THE AIRMASS WILL
GENERALLY BE DRY...HOWEVER...AND THE CHANCE OF CONVECTION WILL
REMAIN LOW. A WEAK HIGH PRESSURE RIDGE WILL BUILD THURSDAY AND THE
AIRMASS WILL CONTINUE TO WARM AND DRY WITH TEMPERATURES RISING
FURTHER ABOVE SEASON NORMALS. A SERIES OF WEAK DISTURBANCES WILL
MOVE THROUGH THE FLOW ALOFT FRIDAY. MOISTURE WILL INCREASE ACROSS
THE REGION AND THE AIRMASS WILL BECOME UNSTABLE...AND THE CHANCE OF
