Area forecast discussion, Aug 1, 1:59 PM MDT, 2 hours 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
159 PM MDT WED AUG 1 2012

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH FRIDAY...
A CLASH OF AIRMASSES ARE OCCURRING ACROSS THE NORTHERN ZONES THIS
AFTERNOON WITH A WARM/DRY AIRMASS MOVING IN FROM THE SOUTH WHILE A
NW PUSH HAS MOVED INTO THE NW ZONES. COOLER/MORE HUMID AIRMASS HAVE
BEEN OVER THE EASTERN ZONES TODAY. A SEVERE THUNDERSTORM DEVELOPED
ON THE TRIPLE POINT IN SOUTHERN SASK NEAR SWIFT CURRENT ABOUT NOON
AND IS MOVING SOUTHEAST...POISED TO POSSIBLY BRING SEVERE WEATHER
OVER THE NE ZONES FOR THE REMAINDER OF THE AFTERNOON.

 THE WARM AND DRY AIRMASS WILL BE BEST ESTABLISHED OVER THE SW ZONES
BUT LIGHT WINDS AND HIGHER HUMIDITY WILL BE IN PLACE OVER THE
EASTERN ZONES. SURFACE LOW PRESSURE OVER S SASK WILL DRAG A COLD
FRONT EAST ACROSS THE AREA AND FIRE UP AFTERNOON THUNDERSTORMS NEAR
THE NORTH DAKOTA BORDER.

THEN THE NEXT BIG SYSTEM WILL BE DROPPING IN FROM THE NORTHWEST.
CLOUDS OVERSPREAD THE AREA THURSDAY NIGHT WITH RAINSHOWERS TO ARRIVE
FRIDAY. TEMPS WILL BE SIGNIFICANTLY COOLER WITH HIGHS ABOUT 15
DEGREES BELOW NORMAL. JAMBA

.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY...
JUST FEW SLIGHT CHANGES TO THE EXTENDED FORECAST BY SLIGHTLY
ADJUSTING THE POPS FOR SATURDAY AND THEN AGAIN ON MONDAY NIGHT AND
TUESDAY. THERE IS STILL NOT MUCH IN THE WAY OF MODEL AGREEMENT SO
THE EXTENDED MODELS SEEM TO BE DIFFERING ON SOLUTIONS FROM THE
12Z TO THE OOZ RUN. THE ECMWF IS TRYING TO SHOW SOME KIND OF
BLOCKING PATTERN FROM MONDAY THROUGH WEDNESDAY WHILE THE GFS SHOWS
A LARGE RIDGE OVER THE NORTHERN ROCKIES. RSMITH
PREVIOUS DISCUSSION...SYNOPTIC SET UP... A LARGE TROUGH OF
COOLER AIR HAS FORMED AS A SPUR OFF THE HUDSON BAY LOW AND
COMBINED A WITH A SHORTWAVE MEANDERING DOWN FROM CENTRAL ALBERTA.
THIS SHOULD SPILL COOL AIR AND SHOWERS INTO SOUTHERN SASKATCHEWAN
AND NORTHEAST MONTANA THEN SLOWLY EXIT TOWARD THE DAKOTAS. TO THE
SOUTH A SUPPRESSED DOME OF HOT HIGH PRESSURE SETS OVER THE DESERT
SOUTHWEST AND REACHES UP TO ABOUT CENTRAL WYOMING. A LARGE RIDGE
EXTENDS UP FROM THIS DOME THROUGH THE PACIFIC NORTHWEST... BRITISH
COLUMBIA... AND INTO THE NORTHWEST TERRITORIES.

FRIDAY NIGHT... THE TROUGH OF COOLER AIR WILL BEGIN EXITING THE
AREA AS SOME WRAP AROUND PRECIP DROPS DOWN BRIEFLY ACROSS THE
NORTHERN SECTIONS OF THE CWA. NOT ANTICIPATING VERY MUCH RAIN AND
RAIN SHOULD ALSO BE HIT OR MISS FOR AREAS THAT DO EXPERIENCE IT.
THE HEAT DOME WILL BEGIN TO BUILD INTO THE PACIFIC NORTHWEST AS THE
TROUGH EXITS TO THE EAST.

SATURDAY THROUGH MONDAY... ANTICIPATED NORTHWEST FLOW PATTERN TO
SLOWLY TRANSITION TO A RIDGE AS IT ARRIVES. CONDITIONS SHOULD
REMAIN DRY THROUGH THIS SET OF PERIODS. WITH A SLOW WARMING
PATTERN THAT SHOULD SPIKE SUNDAY NIGHT OR MONDAY MIDDAY.

MONDAY NIGHT ONWARD... MODELS CONFIDENCE BREAKS DOWN AT THIS
POINT. 12Z EC WANTS TO PLACE US IN SOUTHWEST FLOW AS A HEAT DOME
BREAKS DOWN ACROSS THE FAR WESTERN PART OF THE CONTINENT AND A
COLD PUSH ARRIVES FROM THE CANADIAN PLAINS AGAIN. HOWEVER THE 12Z
EC APPEARS TO GIVE NO REASONING FOR THE HEAT DOME BREAKDOWN ACROSS
THE FAR WEST. THEREFORE I'M MORE INCLINED TO AGREE WITH THE 00Z
GFS WHICH MAINTAINS THIS DOME AND PLACES NEMONT BACK IN DRIER
NORTHWESTERN FLOW. NEWER 00Z EC ALSO APPEARS TO HAVE PULLED INTO
THIS LINE OF LOGIC AS WELL. THE STRENGTH OF THE COLD CANADIAN
PLAINS PUSH IS ALSO UNKNOWN AND THEREFORE COULD BE WARMER DRIER
AND LESS WINDY... OR COOLER MORE UNSTABLE AND WINDY DEPENDING ON
THE TRUE ORIGIN OF THE AIRMASS. HAVE SPLIT THE DIFFERENCE FOR NOW
THROUGH TUESDAY NIGHT. WEDNESDAY TOWARD THE END WILL VERY LIKELY
TRANSITION BACK TO A RIDGE IF THE HEAT DOME TO THE WEST REMAINS
UP. GAH

&&

.AVIATION...
WESTERLY WINDS WILL CONTINUE ACROSS ALL TERMINALS BEHIND A
SURFACE TROUGH ACROSS EASTERN MONTANA. SOME SCATTERED SHOWERS AND
THUNDERSTORMS ARE POSSIBLE AT THE KSDY TERMINAL THIS AFTERNOON AND
EVENING. SOME OF THE STORMS COULD BECOME STRONG TO SEVERE. RSMITH

&&

.FIRE WEATHER...
A POTENT COLD FRONT ASSOCIATED WITH A PACIFIC TROUGH WILL
EFFECTIVELY BREAK DOWN THE UPPER RIDGE...DRIVING A MAINLY DRY COLD
FRONT THROUGH NORTHEAST MONTANA ON THURSDAY. A FIRE WEATHER
WATCH IS IN EFFECT FOR LOW HUMIDITY AND GUSTY SHIFTING WINDS
ASSOCIATED WITH THE COLD FRONT FROM THURSDAY AFTERNOON THROUGH
THURSDAY NIGHT. FIRE WEATHER ZONES 135 AND 136 HAVE BEEN UPGRADED
TO A RED FLAG WARNING. GILCHRIST/JAMBA
