AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GLASGOW MT
925 PM MDT SUN MAY 15 2011

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH TUESDAY...
THE GOES IMAGERY SHOWS THE UPPER CLOSED LOW EXIT REGION IN UTAH
WHICH HAS DEVELOPED AREAS OF ENERGETIC THUNDERSTORMS OVER WESTERN
MONTANA AND SOUTH OF THERE. THESE STORMS ARE EXPECTED TO REMAIN
WEST OF NEMONT TONIGHT FOR CONTINUED CLEAR TO PARTLY CLOUDY
SKIES. THE MAIN CONCERN FOR TONIGHT IS THE WIND. A STRONG SURFACE
HIGH LOCATED OVER THE MANITOBA AND A SURFACE LOW TO THE WEST HAVE
SET UP A STIFF GRADIENT RESULTING IN STRONG SOUTHEASTERLY WINDS.
UPPER WINDS ARE LINED UP TO REINFORCE THE SURFACE WIND...BUT
DECOUPLE AT SUNSET. WIND...WHICH HAS PRODUCED GUSTS OF 35-40 KTS
EARLY THIS EVENING...WILL THEN DIMINISH OVERNIGHT BEFORE
RETURNING TO STRENGTH MONDAY MORNING. SINCE WIND WILL DIMINISH
ONLY OVERNIGHT...WILL CONTINUE THE WIND ADVISORY FOR FORT PECK
LAKE. OTHER THAN TWEAKING WIND...FEW UPDATE CHANGES NEEDED. SCT

PREVIOUS DISCUSSION...
THIS EVENING...A RIDGE EXTENDS UP THE FRONT RANGE OF THE ROCKY
MOUNTAINS. THIS RIDGES IS PINCHED IN BETWEEN A LARGE TROUGH OVER
THE GREAT LAKES REGION WITH COOL AIR BACKING UP OVER THE PLAINS
AND ANOTHER LARGE TROUGH OVER THE PACIFIC NORTHWEST. AT A MORE
LOCAL LEVEL A TIGHTLY PACKED SURFACE PRESSURE GRADIENT IS
GENERATING STRONG WINDS ACROSS THE EASTERN MONTANA BUT SHOULD LET
UP SLIGHTLY OVERNIGHT AS HEATING DROPS OFF AND REDUCES LAPSE RATES
AND MIXING. LOOK FOR WINDY AND MOSTLY CLEAR SKIES OVERNIGHT.

MONDAY THE THROUGH OVER THE PACIFIC NORTHWEST WILL BEGIN MOVING
EAST AND GENERATE A QUASI SURFACE LEE SIDE TROUGH/FRONT THAT
WILL MOVE THE TIGHT PRESSURE GRADIENT EAST.STRONG WINDS AHEAD OF
THIS FRONT WILL KICK UP WITH THE GRADIENT AGAIN TOMORROW AND HAVE
WARRANTED CONDITIONS FOR A HIGH WINDS WATCH IN WIBAUX COUNTY ALONG
THE MONTANA/DAKOTA BORDER. WITH THE PASSAGE OF THE FRONT RAIN
SHOWERS AND A FEW THUNDERSTORMS ARE ALSO EXPECTED TO FORM. CAPE
VALUES ARE LOW BETWEEN 50 TO 200 J/KG WITH FAIRLY THIN PROFILES
BUT DO GO INTO THE FREEZING LEVEL AND ARE ACCOMPANIED BY ENOUGH
SHEAR TO PRODUCE SUPERCELLS. THE WINDOW FOR SUPERCELL PRODUCTION
IS VERY NARROW AS CAPE SHUTS OFF RAPIDLY ACROSS THE REGION AT
SUNDOWN AND THE COLD FRONT BEGINS TO STABILIZE THE ATMOSPHERE.
WINDS AT SUNDOWN SHOULD ALSO QUICKLY SUBSIDE TO MINIMAL VALUES.

TUESDAY...THE FRONT IS EXPECTED TO STALL ACROSS THE REGION. A
SEMI-STABLE SURFACE LAYER FROM THE PREVIOUS NIGHT WILL CARRY OVER
INTO THE DAY AND CLOUD COVER WILL HELP TO CONTINUE THIS SLIGHTLY.
CAPE VALUES ARE ANTICIPATED TO INCREASE ALONG A LIFT ZONE ON THE
STALLED FRONT HOWEVER WITH MINIMAL SHEAR ONLY SHOWERS AND AN
ISOLATED CLAP OF THUNDER ARE CURRENTLY ANTICIPATED. THIS HAS A
SMALL CHANCE TO INCREASE BRIEFLY IN INTENSITY IF A MESOSCALE
SHORTWAVE HIDDEN IN THE SOUTHWEST FLOW MOVES THROUGH THE REGION.
GAH

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...
ANOTHER POTENT PACIFIC TROUGH WILL BRING ANOTHER ROUND OF WET
WEATHER TO NORTHEAST MONTANA TUESDAY NIGHT THROUGH FRIDAY. GIVEN
INCREASING CONFIDENCE TRENDED UP CHANCES FOR PRECIPITATION. ALSO
SLIGHTLY TRENDED DOWN TEMPS GIVEN EXPECTED ONGOING PRECIP.
TEMPERATURES WITH THIS SYSTEM DO LOOK MUCH WARMER THEN LAST WEEKS
STORM...THUS NO SNOW IS POSSIBLE. GUSTY EAST WINDS ARE ALSO A GOOD
BET WITH THE STORM THROUGH THE WORK WEEK.

THE MODELS DISAGREE WITH HOW TO HANDLE THE WEEKEND AND THE DEMISE
OF THE STORM SYSTEM OVER THE WEEKEND. THE CONSENSUS IS THAT THE
LOW WILL LINGER OVER THE AREA INTO THE WEEKEND AND SLOWLY
DISSIPATE. THUS HELD ON TO SOME MENTION OF PRECIP WITH NEAR NORMAL
TEMPS. GILCHRIST

PREVIOUS LONG TERM DISCUSSION...A LONG WAVE UPPER TROUGH
DEVELOPING OVER THE WEST WILL BRING A RETURN TO UNSETTLED
CONDITIONS OF WETTER AND UNSTABLE WEATHER WITH AROUND NORMAL
TEMPERATURES WITH THE SOUTHERLY FLOW.

THE CLOSED UPPER LOW THAT CAN CURRENTLY BE SEEN ON THE WATER VAPOR
GOES IMAGERY OFF THE WEST COAST WILL WORK ITS WAY INTO THE GREAT
BASIN REGION LATE TUESDAY WHERE THE BASE OF THE TROUGH WILL PICK
UP PACIFIC MOISTURE FROM THE WARMER CALIFORNIA REGION AND SEND IT
NORTH INTO MONTANA...SIMILAR TO PATTERN LAST WEEK. THE TROUGH
ANCHORED BY A STACKED CLOSED LOW SYSTEM MOVES EAST INTO THE
CENTRAL ROCKIES ON WEDNESDAY WHERE THE SURFACE LOW WILL BEGIN TO
PICK UP ADDITIONAL MOISTURE FROM THE GULF STATES...SENDING IT INTO
EASTERN MONTANA. BY THURSDAY AND FRIDAY THE INVERTED SURFACE
TROUGH LIFTS FARTHER NORTH INTO THE LOCAL REGION BRINGING MODERATE
TO HEAVY QPF.

UNCERTAINTY EXISTS THIS FAR OUT AS TO WHERE AND HOW MUCH THE
HIGHEST QPF AMOUNTS WILL END UP. THE MODELS FALL OUT OF AGREEMENT
FOR THE WEEKEND BUT GENERAL TROUGHY CONDITIONS ARE LIKELY. SCT

&&

.AVIATION...
VFR. STRONG WINDS WILL BE OF SOME CONCERN THROUGH MONDAY
AFTERNOON WITH A BRIEF LULL TONIGHT. WINDS WILL BE SOUTHEASTERLY
AT 20 TO 30 KTS AND GUSTING UP TO 40 KTS AT TIMES...DECREASE SOME
TONIGHT...BEFORE AGAIN REDEVELOPING AROUND SUNRISE MONDAY. WITH
PERIODS OF LIGHTER WINDS AT THE SURFACE TONIGHT...WIND SHEAR WILL
BE OF CONCERN. GFF/GILCHRIST/PROTON

&&

.HYDROLOGY...
AREA RIVERS...CREEKS...AND STREAMS WILL CONTINUE TO FALL OVER THE
NEXT FEW DAYS THANKS TO DRY WEATHER. A FLOOD ADVISORY REMAINS IN
EFFECT FOR THE MUSSELSHELL RIVER ON THE PETROLEUM/GARFIELD COUNTY
LINE.

CONFIDENCE IS GROWING IN ANOTHER WET PACIFIC STORM SYSTEM
IMPACTING NORTHEAST MONTANA TUESDAY INTO FRIDAY. SIGNIFICANT
RAINFALL IS POSSIBLE WITH THIS SYSTEM...THEREFORE ADDITIONAL RISES
ON AREA CREEKS...STREAMS AND RIVERS WILL BE POSSIBLE. PLEASE
CONTINUE TO MONITOR THE LATEST FORECASTS FOR DETAILS.
