AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1140 PM MDT SUN MAY 8 2016

AVIATION SECTION UPDATED.

.UPDATE...

907 PM UPDATE...SCATTERED THUNDERSTORMS WITH GUSTY WINDS, BRIEF
HEAVY RAIN, AND FREQUENT LIGHTNING WILL CONTINUE TO WEAKEN THROUGH
MIDNIGHT AS THEY MOVE EAST OUT OF THE AREA WITH A PACIFIC FRONT.
GUSTY NORTH WINDS HAVE ALREADY MOVED INTO THE CUT BANK AREA AND
SURFACE PRESSURE IS STARTING TO RISE, SO IT SEEMS AS IF THE
CANADIAN COLD FRONT HAS MOVED THROUGH THAT AREA ALREADY. HAVE
THEREFORE ADJUSTED THE WIND FORECAST TO SPEED UP THE SWITCH TO
MORE NORTHERLY WINDS ACROSS NORTH CENTRAL MONTANA BY A COUPLE OF
HOURS AND INCREASED THEM BY ABOUT 5 TO 10 MPH TO REFLECT THE
POTENTIAL FOR STRONGER GUSTS. OTHERWISE, THE FORECAST APPEARS TO
BE ON TRACK. TEMPERATURES ARE TRENDING AS EXPECTED, AND SHOWERS
SHOULD BECOME MORE NUMEROUS OVERNIGHT ALONG AND BEHIND THE
CANADIAN COLD FRONT. COULSTON

620 PM UPDATE...MADE SOME ADJUSTMENTS TO THE CURRENT FORECAST. A
THUNDERSTORM IN THE BOZEMAN AREA PRODUCED BRIEF HEAVY RAIN AND
SOME OF THESE PULSING STORMS MAY ALSO PRODUCE BRIEF STRONG WINDS
GUSTS AND SMALL HAIL, SO HAVE INCREASED POPS ACROSS THE AREA AND
ADDED THESE ATTRIBUTES TO THE FORECAST WORDING. ALSO,
PRECIPITATION ASSOCIATED WITH THE CANADIAN COLD FRONT IS ALREADY
MOVING INTO FAR NORTHWEST MONTANA, SO HAVE INCREASED POPS OVER
GLACIER NATIONAL PARK THROUGH THIS EVENING. COULSTON

&&

.AVIATION...
UPDATED 0540Z.

A BAND OF SHOWERS AND THUNDERSTORMS CONTINUES TO TRACK EAST OF A
LINE FROM KHVR TO KLWT. THIS ACTIVITY WILL EXIT THE FORECAST AREA BY
AROUND 0800Z. AT THE SURFACE...A STRONG COLD FRONT HAS PASSED
THROUGH KCTB/KGTF/KHVR PRODUCING A SHIFT TO NORTH WINDS WITH GUSTS
TO 35KT. EXPECT THIS FRONT / WIND SHIFT TO AFFECT KHLN/KLWT/KBZN
LATER TONIGHT. VFR CONDITIONS WILL DETERIORATE TO IFR AS LOW CLOUDS,
THEN PRECIPITATION DEVELOPS AT ALL TERMINALS MONDAY. PRECIPITATION
SHOULD HOLD OFF FURTHER EAST AT KLWT/KHVR UNTIL LATE MONDAY EVENING.
THE PREVAILING FORECAST CARRIES -RA BUT NOTE THAT SNOW LEVELS WILL
BE DROPPING THROUGH FL050 MONDAY EVENING. IT IS POSSIBLE THAT RAIN
COULD MIX WITH OR CHANGE TO SNOW LATE IN THE PERIOD. PN

.PREV DISCUSSION...
/ISSUED 203 PM MDT SUN MAY 8 2016/

THIS AFTERNOON THROUGH TUESDAY EVENING...GORGEOUS WEATHER ACROSS THE
REGION THIS AFTN, WITH A MIX OF CLEAR SKIES AND SCATTERED AREAS OF
CUMULUS CLOUDS, MAINLY OVER THE HIGH PEAKS AND MTN SNOWFIELDS.
CURRENT WATER VAPOR SATELLITE IMAGERY SHOWS A WEAKENING UPPER-LEVEL
DISTURBANCE HAS REACHED THE ROCKY MTN FRONT AND SHOULD MAKE A BIT
MORE HEADWAY TO THE EAST, BUT WILL PROBABLY WASHOUT ALONG/WEST OF
THE INTERSTATE 15 CORRIDOR WITH LITTLE MORE THAN A STRAY SHOWER OR
TWO.  THE PRIMARY CONCERN FOR US IS THE LOW PRESSURE PRESENTLY
MOVING THROUGH BC/WA/OR WITH ITS ASSOCIATED COLD FRONT LOCATED FROM
THE FAR NORTHWEST MT DOWN TO THE SE CORNER OF OREGON. THE FRONT
SHOULD SHOULD REACH THE ROCKY MTN FRONT IN A FEW HOURS AND THEN MOVE
INTO THE CENTRAL PLAINS THIS EVENING, SETTING OFF SOME SCATTERED
SHOWERS AND A FEW WEAK, SHORT-LIVED THUNDERSTORMS THAT MAY PRODUCE
SOME OUTFLOW GUSTS OF 30-40 MPH. SHORT-TERM MODELS REMAIN IN CLOSE
AGREEMENT THAT THE CENTRAL LOW PRESSURE AREA OF THIS SYSTEM WILL
MOVE FROM SOUTHEAST BC TO SOUTHWEST MT TOMORROW WITH EAST-NORTHEAST
FLOW ALOFT BRINGING IN A BROAD MOISTURE PLUME THAT WILL LEAD TO
WIDESPREAD VALLEY RAIN/MTN SNOW FROM MON MORNING THROUGH TUES AFTN.
LATEST PRECIPITATION PROJECTIONS INDICATE MOST LOCATIONS WILL
RECEIVE 0.25 TO 0.75 INCH. PRECIP WILL START AS RAIN IN THE MTNS BUT
CHANGE OVER TO SNOW MON NIGHT AS SNOW LEVELS DROP TO AROUND 5000-
5500 FT. STILL LOOKING AT SNOWFALL TOTALS OF 6-10 INCHES NEAR KINGS
HILL PASS, BIG SKY, AND THE NORTHERN ROCKY FRONT WITH 1-4 INCHES IN
THE FOOTHILLS OF MANY OF THE CENTRAL/SOUTHWEST MTNS.  THE SYSTEM
WILL MAKE SLOW PROGRESS ON TUES, MOVING EAST ALONG THE MT/WY BORDER.
THAT WILL KEEP THE RAIN/SNOW GOING UNTIL AROUND MIDDAY WHEN WE'LL
START TO SEE GRADUAL CLEARING FROM WEST TO EAST.  MUCH COOLER TEMPS
ON THE WAY AS THE SYSTEM PASSES THROUGH, WITH HIGHS ONLY IN THE 40S
AND LOW 50S ON MON/TUES.
WARANAUSKAS

TUESDAY NIGHT THROUGH SUNDAY...MEDIUM RANGE MODELS REMAIN IN
GOOD AGREEMENT FOR THE TUESDAY NIGHT THROUGH FRIDAY TIME PERIOD.
UPPER LEVEL TROUGH THAT BRINGS PRECIPITATION TO THE REGION MONDAY
AND TUESDAY IS STILL EXPECTED TO MOVE EAST OF THE FORECAST AREA AND
FORM A CUTOFF LOW OVER THE DAKOTAS BY WEDNESDAY MORNING. AS HAS BEEN
THE CASE FOR THE LAST FEW DAYS, THIS PATTERN WILL LEAVE MONTANA
BENEATH NORTHWEST FLOW ALOFT THROUGH THURSDAY. ISOLATED SHOWERS
LINGER OVER PORTIONS OF THE REGION DURING THIS TIME UNTIL A BAND OF
UPPER LEVEL ENERGY SWEEPS INTO NORTHWEST MONTANA THURSDAY AFTERNOON
FOR A ROUND OF SCATTERED SHOWERS AND THUNDERSTORMS ACROSS MUCH OF
THE REGION. WEAK SHORTWAVE RIDGING BUILDS OVER THE NORTHERN ROCKIES
FRIDAY AND SATURDAY BUT MODELS PERSIST IN KEEPING ISOLATED POPS OVER
THE REGION AS PACIFIC MOISTURE PUSHES THROUGH THE RIDGE AXIS. FOR
SATURDAY NIGHT AND SUNDAY MODEL SOLUTIONS DIVERGE SO I HAVE CONTINUED
TO KEEP NEAR CLIMATOLOGICAL POPS AND TEMPERATURES IN PLACE FOR THE
REMAINDER OF THE WEEKEND. MPJ
