AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
1007 AM MDT FRI JUL 8 2011

.SHORT TERM...FOR NORTHEAST MONTANA...TODAY THROUGH SUNDAY...
UPDATE...STRONG CONVECTION HAS YET TO DEVELOP THIS
MORNING...THANKS TO AMPLE CLOUD COVER COVERING MOST OF NEMONT.
HOWEVER SHOWER ACTIVITY IS ONGOING THUS UPDATED TO TREND UP POPS
ACROSS MUCH OF THE AREA. ALTHOUGH WINDS CURRENTLY REMAIN
RELATIVELY LIGHT OVER FORT PECK LAKE...STILL EXPECT AN INCREASE
THIS AFTERNOON BEHIND THE FRONT SO WILL LEAVE IT AS IS. GILCHRIST

PREVIOUS DISCUSSION...THE MAJOR STORM SYSTEM MOVES EAST OF THE CANADIAN
ROCKIES AND OUT OVER THE PRAIRIE PROVINCES TODAY WHERE THE LOW
CENTERS STACK UP. THIS CYCLONIC STORM SYSTEM SENT A WAVE ACROSS
THE NORTHEAST MONTANA EARLY THIS MORNING THAT IS ASSOCIATED WITH A
SURFACE TROUGH EXTENDING FROM THE STORM CENTER IN ALBERTA. THIS
WAVE PRODUCED THUNDERSTORMS AND RAIN SHOWERS ALL NIGHT THAT WILL
CONTINUE TODAY. BEHIND THE WAVE CONDITIONS WILL BEGIN TO CLEAR
FROM THE WEST. MOST SHOWERS AND THUNDERSTORMS TODAY WILL BE IN THE
EASTERN ZONES BEFORE MOVING INTO NORTH DAKOTA AND SASKATCHEWAN.
MODELS ARE SHOWING MODERATE TO HEAVY RAIN IS POSSIBLE IN THOSE
ZONES...ESPECIALLY IN THE NORTHEAST. THE STORMS WILL FIND A MORE
UNSTABLE ENVIRONMENT THERE AND SOME STORMS COULD BECOME SEVERE
WITH LARGE HAIL...DAMAGING WINDS AND HEAVY RAIN BEFORE EXITING THE
AREA.

TONIGHT...THE STORM CENTER MOVES PARTLY INTO SASKATCHEWAN AND THE
ASSOCIATED WAVE WILL HAVE MOVED OUT OF THE LOCAL AREA. HOWEVER A
SECONDARY COLD FRONT SWINGS ACROSS THE AREA INITIATING A FEW
THUNDERSTORMS MAINLY SOUTH OF THE CWA. BUT SOME OF THE EVENING
THUNDERSTORMS COULD NUDGE NORTH INTO OUR AREA.

SATURDAY THROUGH SUNDAY...THE STORM CENTER MOVES FULLY INTO
SASKATCHEWAN SATURDAY. THE CYCLONIC FLOW...SURFACE AND
ALOFT...WILL BE REINFORCING. SO SATURDAY AFTERNOON COULD END UP
WINDY AS DRIER AIR IS PULLED ACROSS THE CWA FROM THE WEST. ON SUNDAY
THE CANADIAN STORM MOVES FARTHER EAST INTO MANITOBA. THIS WILL
ALLOW AN UPPER LEVEL RIDGE TO BEGIN BUILDING UP OVER THE NORTHERN
ROCKIES.

THE CANADIAN STORM SYSTEM WILL PUSH THE WARM AIR BOUNDARY SOUTH OF
NEMONT. SO TEMPERATURES WILL TREND COOLER THAN LATELY TO A MORE
SEASONAL LEVEL FOR THE WEEKEND. SCT

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...
AN UPPER RIDGE OVER MONTANA WILL KEEP SUNDAY NIGHT DRY.

THE RIDGE AXIS SHIFTS EAST INTO THE DAKOTAS ON MONDAY. THIS WILL TURN
THE FLOW ALOFT OVER EASTERN MONTANA BACK TO THE SOUTHWEST AS
ANOTHER UPPER TROUGH/LOW MOVES INTO THE WEST COAST. THIS UPPER LOW
WILL REMAIN STATIONARY IN THE PACIFIC NORTHWEST FOR SEVERAL DAYS
WITH SOUTHWEST FLOW ALOFT OVER MONTANA. A LEE SIDE
TROUGH POSSIBLY A SURFACE LOW WILL DEVELOP OVER CENTRAL MONTANA ON
MONDAY AND REMAIN IN PLACE FOR A FEW DAYS. PERIODIC SHORTWAVES IN
THE SW FLOW ALOFT WILL COMBINE WITH THE UNSTABLE AIR OVER CENTRAL
AND EASTERN MONTANA TO PROVIDE CHANCES FOR THUNDERSTORMS STARTING
ON MONDAY AND CONTINUING THE REMAINDER OF THE WEEK. FORRESTER

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL MOST OF THE TIME WITH MID AND HIGH
CLOUDS TODAY. SHOWERS AND THUNDERSTORMS WILL PROVIDE BRIEF
PERIODS OF MVFR VISIBILITIES AND CEILINGS. A COLD FRONT WILL SHIFT
WINDS TO THE WEST BY AFTERNOON AT KGGW AND THE OTHER TAF SITES
THIS AFTERNOON WITH SPEEDS OF 15 TO 20 KNOTS. LOOK FOR CLEAR SKIES
TONIGHT WITH WEST TO NORTHWEST WINDS 5 TO 10 KNOTS.
