DISCUSSION
WEATHER PATTERN OVERVIEW:
STACKED SURFACE AND UPPER LOW WILL DRIFT FROM SOUTHERN
SASKATCHEWAN TO MANITOBA TONIGHT. THE STRONGEST WINDS WILL SUBSIDE
AND THE HIGH WIND WARNING EXPIRING AT MIDNIGHT LOOKS GOOD. A
BLOWING DUST ADVISORY IS IN EFFECT UNTIL 6 PM AND THIS ALSO LOOKS
LIKE A GOOD ENDING POINT.
FRIDAY, THE WINDS WILL INCREASE A BIT BUT NOT BE AS STRONG AS
TODAY. THE SURFACE LOW WILL DRIFT INTO WESTERN ONTARIO WHILE A
SLOW MOVING COLD FRONT DROPS SOUTH CLOSE TO THE MONTANA/CANADA
BORDER.
AN UPPER TROUGH WILL MOVE INTO MONTANA ON SUNDAY ALLOWING AN
INCREASE IN LIFT AND POSSIBLY RAIN FOR THE AREA. THE MODELS ARE
SHOWING THE UPPER LOW TO DIG INTO THE CENTRAL ROCKIES MONDAY THAT
WILL PUSH THE PRECIPITATION SHIELD TO OUR SOUTH BUT THE CWA MAY BE
LUCKY ENOUGH TO BE ON THE NORTHERN EDGE OF IT. SOME OF THE MODELS
ARE SHOWING IT TO BE COLD ENOUGH FOR SNOW. WEATHER GRIDS RIGHT NOW
SPELLING OUT FOR JUST SUNDAY NIGHT. WILL HAVE TO KEEP AN EYE OUT
FOR THIS ONE IF THE MODELS BRING THIS SYSTEM FURTHER NORTH, THERE
COULD BE SIGNIFICANT IMPACTS.
THE UPPER TROUGH BEGINS TO LIFT OUT TUESDAY SO A RETURN TO MORE
NORMAL CONDITIONS CAN BE EXPECTED FOR THE REMAINDER OF THE SEVEN
DAYS.

A BLEND WITH THE GLAMP IN WIND GRIDS WERE MADE. NO OTHER
DEVIATIONS WERE MADE. TFJ
