AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
829 PM MDT WED SEP 12 2012

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH FRIDAY...
UPDATED THE FORECAST TO LOWER TEMPERATURES TONIGHT SLIGHTLY ACROSS
THE NORTHERN ZONES. ALSO LET THE RED FLAG WARNING EXPIRE FOR TODAY
AND CONTINUED THE FIRE WEATHER WATCH FOR FRIDAY. REST OF THE
FORECAST LOOKS GOOD. RSMITH

PREVIOUS DISCUSSION...WATER VAPOR IMAGERY AND 500 MB HEIGHT FIELD
SHOWS A DYNAMIC WEATHER PATTERN ACROSS THE REGION. CURRENTLY...THE
LAST SHORT WAVE PUSH...EMBEDDED WITHIN THE UPPER LEVEL TROUGH
DRAPED ACROSS THE CANADIAN/U.S. BORDER...IS PASSING THROUGH
CENTRAL AND EASTERN MONTANA TODAY. THIS WILL ACT TO RE-ENFORCE THE
COLD CANADIAN AIR MASS OVER THE NORTHERN HIGH PLAINS AGAIN FOR
NEAR FREEZING TEMPERATURES TONIGHT.

SHORT TERM FORECAST CHALLENGES WILL FOCUS ON TEMPERATURES
INITIALLY...THEN FIRE WEATHER CONCERNS FOR FRIDAY.

LATER TONIGHT THROUGH FRIDAY...THE SMALL UPPER LEVEL RIDGE OF HIGH
PRESSURE CURRENTLY OVER SOUTHERN CALIFORNIA WILL EXPAND TO COVER
MOST OF THE WESTERN STATES REGION...INCLUDING THE NORTHERN AND
CENTRAL HIGH PLAINS REGIONS. THIS RIDGE OF HIGHER PRESSURE WILL
ALLOW TEMPERATURES TO CLIMB BACK ABOVE NORMAL LEVELS.

THE EFFECTS OF THIS INCREASED WARMTH WILL CULMINATE ON FRIDAY WITH
HEIGHTENED FIRE WEATHER CONCERNS. DECIDED TO ISSUE A FIRE WEATHER
WATCH HIGHLIGHTING THESE CONCERNS. SEE FURTHER INFORMATION IN THE
FIRE WEATHER DISCUSSION BELOW. BMICKELSON

.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY...
TWEAKED GRIDS SLIGHTLY TO MATCH BETTER WITH NEWEST MODEL DATA EARLY
IN THE PERIOD...MAINLY WITH WINDS TEMPS AND HUMIDITIES. GFS SEEMS TO
BE MORE ROBUST WITH THE FRONT DROPPING IN ON SATURDAY. DOESN/T LOOK
TO BE A BIG DEAL IN REGARDS TO FIRE WEATHER AS HIGHER HUMIDITY MOVES
IN. REST OF FORECAST LOOKED GOOD. JAMBA

PREVIOUS DISCUSSION...
THE EXTENDED PERIOD STARTS OUT WITH ZONAL FLOW ALOFT ACROSS THE
NORTHERN ROCKIES THROUGH SUNDAY MORNING. A SHORTWAVE TROUGH DIVES
SOUTHEAST OUT OF ALBERTA AND DRAGS A STRONG COLD FRONT ACROSS
EASTERN MONTANA SUNDAY AFTERNOON. THIS SHORTWAVE WILL HELP PUT THE
NORTHERN HIGH PLAINS UNDER A LARGE UPPER TROUGH...WHICH EASTERN
MONTANA WILL BE UNDER THE WESTERN SIDE OF THIS UPPER TROUGH.

THE SHORTWAVE COLD FRONT COMBO WILL BE THE BEST CHANCE OF
PRECIPITATION IN THE EXTENDED PERIOD...AND IT IS ONLY A SLIGHT
CHANCE. SO KEPT POPS UNDER 20 PERCENT GIVEN THE OVERALL CONTINUED
DRY CONDITIONS AND THE AREA THIS AIR MASS IS MOVING FROM.
CONTINUED THE POPS THROUGH SUNDAY NIGHT AND ALSO DECIDED TO LOWER
MONDAY HIGH TEMPS SINCE A COOLER AIR MASS WILL MOVE IN BEHIND THE
COLD FRONT ACROSS THE REGION. THE LATEST ECMWF...GEM AND GFS
RUNS SHOW THE COOLER TEMPERATURES...IN FACT TEMPERATURES WILL BE
ABOUT 7 TO 10 DEGREES BELOW AVERAGE ON MONDAY.

AFTER MONDAY DIDN/T MAKE ANY CHANGES TO THE FORECAST THROUGH
WEDNESDAY NIGHT. FLOW ALOFT DURING THIS TIME FRAME IS OUT OF THE
NORTHWEST ACROSS EASTERN MONTANA WITH A WEAK SHORTWAVE MOVING
ACROSS SOUTHEAST SASKATCHEWAN TUESDAY AFTERNOON. THIS SHOULD ONLY
RESULT IN SOME MID AND HIGH LEVEL CLOUD COVER FOR NORTHEAST
MONTANA. RSMITH

.AVIATION...
