AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BILLINGS MT
958 AM MDT MON MAR 26 2012

.SHORT TERM...VALID FOR TDY AND TUE...

MINOR UPDATES THIS MORNING TO TRY TO CONVEY MORE OF A THUNDERSTORM
THREAT AS OPPOSED TO THUNDERSTORM/SHOWER MIX. BIGGEST CONCERN IS
THE POSSIBILITY OF LINEALLY ORGANIZED CONVECTION THIS AFTERNOON
PRODUCING A DECENT GUST OF WINDS DUE TO HIGH BASES AND FAST
MOMENTUM ALOFT WITH SOME SHEAR. WILL BE ASSESSING THE THREAT TO
SEE IF A HIGH WIND WARNING IS WARRANTED ACROSS THE CENTRAL ZONES
EARLY THIS EVENING/VERY LATE THIS AFTERNOON. WILL LIKELY CONVERT
THE HIGH WIND WATCH IN THE EAST TO A WARNING BUT WILL BE
ANTICIPATING AN UPDATE AROUND 100 PM TO COVER BOTH SCENARIOS.
BORSUM

PREVIOUS DISCUSSION FOLLOWS...

A VERY DYNAMIC WEATHER SYSTEM TO IMPACT THE FORECAST AREA THE
NEXT 36 HOURS. THIS SYSTEM WAS SHIFTING PRETTY QUICKLY INTO
SOUTHERN NEVADA THIS HOUR. ORDINARILY UPPER LOWS MOVE SLOWER BUT
THIS ONE WAS BEING PUSHED BY A 130KT JET OVER THE EASTERN
PACIFIC. THE UPPER LOW WILL MOVE INTO NORTHEAST WYOMING LATE THIS
AFTERNOON. MIXING WILL OCCUR AHEAD OF THE SYSTEM AND THIS MIXING
WILL INVOLVE DRY AIR BELOW 700MB. WATER VAPOR IS INDICATING THIS
TOO AS A MID LEVEL MOISTURE PLUME FROM COLORADO TO EASTERN
MONTANA THIS HOUR WAS SHIFTING EAST QUICKLY THIS MORNING. DRIER
AIR TO THE WEST OF THIS MOISTURE PLUME WILL WORK INTO THE AREA
THIS AFTERNOON AND MIX DOWN. HUMIDITIES WILL FALL INTO THE TEENS
AND LOWER 20S. SOUTH WINDS WILL INCREASE OVER THE SOUTHEAST FOR
FIRE WEATHER CONCERNS. HIGHS TODAY WILL BE UNSEASONABLY WARM WITH
READINGS REACHING THE UPPER 70S AROUND MILES CITY.

STRONG UPPER DIVERGENCE WILL MOVE THROUGH THE AREA THIS AFTERNOON
AND THIS WILL GENERATE CONVECTION. DRY LOW LEVELS WILL CAUSE
CONVECTION TO BE HIGH BASED. THE ATMOSPHERE WILL BE UNSTABLE
ENOUGH TO GENERATE WEAK CAPE WITH SOME MID LEVEL MOISTURE
ASSOCIATED WITH THE UPPER LOW AND THUS WILL INCLUDE
THUNDERSTORMS. SHOWERS WILL DEVELOP OVER THE WEST THIS AFTERNOON
AND SPREAD EAST THIS EVENING. THE THREAT WILL BE BIG WINDS WITH
THESE SHOWERS. SPEAKING OF WINDS...A STRONG COLD FRONT WILL BE
PUSHED ON BY THE SHOWERS AND INCREASING 850MB WINDS WITH A
TIGHTENING SURFACE PRESSURE GRADIENT AS A SURFACE LOW STRENGTHENS
QUICKLY OVER EASTERN MONTANA. WESTERN AND CENTRAL ZONES WILL HAVE
ASCENT WITH UPPER DIVERGENCE...SO WINDS WILL BE GUSTY AND COME IN
WAVES AS SHOWERS MOVE THROUGH. SOME WIND GUSTS TO 55 MPH CAN BE
EXPECTED...SO BUMPED WINDS UP CENTRAL AND WEST. THE COLD FRONT
WILL RIP INTO THE EAST DURING THE EVENING AS 850MB WINDS INCREASE
TO 55KTS. SHOWERS WILL SHIFT ACROSS THE EAST DURING THE EVENING
AND THIS WILL CAUSE THE LOW LEVELS TO COOL. THE MODELS WERE
HINTING AT SOME SUBSIDENCE MOVING INTO THE FAR EAST LATE TONIGHT
TO PUSH THE BIG WINDS DOWN DESPITE THE RAIN COOLED AIR. WILL
ISSUE A HIGH WIND WATCH FOR THE FOUR EASTERN COUNTIES FOR TONIGHT
AND TUESDAY MORNING. NOT A COMMON TIME FOR STRONG WINDS...BUT THE
SURFACE PRESSURE GRADIENT CERTAINLY IS WRAPPED UP ENOUGH TO
PRODUCE THEM.

SHOWERS WILL TAPER OFF FROM WEST TO EAST OVERNIGHT. WINDS WILL
DECREASE OVER CENTRAL AND WESTERN ZONES OVERNIGHT AS THE SURFACE
LOW PULLS AWAY. THE WINDS WILL STAY STRONG OVER THE EAST UNTIL
TUESDAY AFTERNOON. COOLER TEMPERATURES ARE EXPECTED BEHIND THE
FRONT FOR TUESDAY...BUT RIDGING WILL QUICKLY MOVE IN AND WITH
PERSISTENT DOWNSLOPE FLOW...THE COOLER AIR WILL MODIFY QUITE
READILY. TUESDAY WILL BE DRY WITH RIDGING. TWH

.LONG TERM...VALID FOR WED...THU...FRI...SAT...SUN...

ONCE AGAIN...LITTLE IN THE WAY OF CHANGES AS MODELS REMAIN IN
PRETTY GOOD AGREEMENT WITH REGARD TO PROGRESSIVE PATTERN IN PLACE
FOR THE EXTENDED PERIOD. THERE ARE SOME DIFFERENCES IN TIMING
BETWEEN THE MODELS...BUT CLOSE ENOUGH WHERE CAN GET PRETTY GOOD
ESTIMATE.

RIDGE TO START THE PERIOD ON WEDNESDAY GIVES WAY QUICKLY TO
UNSTABLE SOUTHWEST FLOW. SHORTWAVES ARE ANTICIPATED INTO THE
REGION LATE WEDNESDAY/EARLY THURSDAY...AND AGAIN FRIDAY. THE GFS
IS LESS AGGRESSIVE WITH THE SECOND SHORTWAVE...BUT IS
IDENTIFIABLE...AND EC BRINGS SHOWERS THROUGH THE REGION...SO HAVE
OPTED TO INCLUDE SLIGHT POPS THROUGH THE REGION. BEST CHANCES FOR
PRECIP WITH THESE SYSTEMS WILL BE IN THE HIGH TERRAIN. CONFIDENCE
IS RELATIVELY LOW FOR SIGNIFICANT SHOWER/THUNDER ACTIVITY...BUT
CANNOT RULE OUT AS EXPECT SOME PACIFIC MOISTURE TO MAKE IT INTO
PLAINS WITH THESE WAVES IN SW FLOW. TEMPS WILL CONTINUE TO BE
AROUND 20 DEGREES ABOVE AVERAGE THROUGHOUT THIS
PERIOD...GENERALLY AROUND 70 DEGREES.

LOOKS LIKE AN AMPLIFIED RIDGE BUILDS IN SATURDAY IN ADVANCE OF A
STRONG PACIFIC LOW AND ASSOCIATED COLD FRONT. RIDGING AND
PREFRONTAL WARMING SHOULD PUSH TEMPS UPWARD...APPROACHING 80 IN
THE EASTERN ZONES. HIGH CLOUDS FROM MOUNTAIN SHOWERS AND
CONVECTION ARE LIKELY TO SLIGHTLY INHIBIT WARMING IN THE WEST BUT
SHOULD STILL REACH 70. STRONG SPRING WEATHER SYSTEM PUSHES INTO
THE REGION LATE SATURDAY THROUGH SUNDAY...AND SHOULD BRING SHOWER
TO THE ENTIRE REGION OVERNIGHT. MODELS DIVERGE SIGNIFICANTLY AT
THIS POINT. HAVE TRENDED POPS WITH THE GFS AT THIS TIME AS
CONTINUES WITH UPPER TROF MOVING THROUGH THE REGION. HAVE KEPT
SOMEWHAT MODERATE TEMPS IN PLACE...BUT TRENDING DOWNWARD SUNDAY
AND MONDAY. IF THE GFS PANS OUT...TEMPS WILL NEED TO COME DOWN
MUCH FURTHER. AAG

&&

.AVIATION...

MVFR CIGS WILL CONTINUE IN EASTERN MT ALONG THE ND/SD
BORDER...INCLUDING KBHK...FOR THE NEXT FEW HOURS BEFORE IMPROVING
TO VFR. OTHERWISE...VFR CONDITIONS WILL PREVAIL ACROSS MUCH OF THE
REGION INTO EARLY AFTERNOON.

A STRONG DISTURBANCE WILL BRING INCREASING CHANCES OF SHOWERS AND
A THREAT OF THUNDERSTORMS BY MID TO LATE AFTERNOON...SPREADING
FROM WEST AND SOUTHWEST TO EAST AND NORTHEAST THROUGH THIS EVENING.
EXPECT INCREASED SOUTHWEST WINDS BY THIS AFTERNOON...ESPECIALLY
AROUND KLVM AND KSHR. EXPECT STRONG WEST TO NORTHWEST WINDS
ACROSS THE AREA THIS EVENING. THERE WILL BE MOUNTAIN OBSCURATIONS
THROUGH THE DAY. STC
