DISCUSSION...



PRAIRIES...FAIRLY QUIET DAY ON TAP TODAY BEFORE THE NEXT INCOMING

SYSTEM IMPACTS THE PROVINCE BEGINNING LATE TUESDAY AFTERNOON.

THIS SYSTEM WILL MOVE OVER NORTHERN ALBERTA, BRINGING ANOTHER ROUND

OF MIXED PRECIPITATION, AND MORE FREEZING RAIN. THE AREAS THAT LOOK

TO BE MOST IMPACTED FROM THE INCOMING SYSTEM WILL BE FROM HIGH LEVEL

AND PEACE RIVER IN THE WEST TUESDAY NIGHT, TO FORT MCMURRAY BY

WEDNESDAY MORNING. THIS SAME SYSTEM WILL ALSO BRING SOME FREEZING

RAIN TO THE LALOCHE REGION OF NORTHERN SASKATCHEWAN. TO THE NORTH OF

THIS FREEZING RAIN, HEAVIER SNOW IS EXPECTED WITH 5-10 CM

ANTICIPATED BY WESDNESADY MORNING ACROSS NORTHWESTERN SASKATCHEWAN

AND THE FORT CHIPEWAYAN REGION. IN THE SOUTH, ABNORMALLY WARM

TEMPERATURES ARE ANTICIPATED WITH RECORDS EXPECTED TO BE BROKEN WITH

THE INCOMING UPPER RIDGE.



TWO WAVES OF LIGHT SNOW WILL MOVE THROUGH THE EASTERN PRAIRIES OVER

THE NEXT 36 HOURS. THE FIRST WILL DROP SOUTHEAST THROUGH SOUTHERN

SASKATCHEWAN TODAY, LEAVING BEHIND A FURTHER 1 TO 3 CM OF SNOW OVER

THE SOUTHEAST CORNER OF THE PROVINCE. THE OTHER WAVE OF SNOW WILL

TRACK ACROSS NORTHERN SASKATCHEWAN INTO MANITOBA OVERNIGHT INTO

TUESDAY. SNOW WILL TAPER OFF FROM WEST TO EAST LATER TUESDAY, LEAVING

BEHIND A COUPLE CENTIMETRES OF SNOW ACROSS PARTS OF NORTHERN AND

CENTRAL MANITOBA, WHILE A LIGHT DUSTING FALLS OVER THE SOUTH.



AFTER THIS SYSTEM PASSES, A BUILDING UPPER RIDGE WILL BRING MILD

TEMPERATURES TO SOUTHERN SASKATCHEWAN AND SOUTHERN MANITOBA THROUGH

THE LATTER PORTIONS OF THE WEEK.



NT...EXITING NT LOW WILL CONTINUE TO BRING SOME LIGHT SNOW TO AREAS

AROUND GREAT SLAVE LAKE, WITH ROUGHLY 2 CM OF SNOW EXPECTED TODAY.

OTHERWISE, THE NEXT SYSTEM OF NOTE WILL BE THE SAME SYSTEM

AFFECTING NORTHERN ALBERTA ON TUESDAY NIGHT WHERE 5-10 CM OF SNOW IS

EXPECTED TO FALL FROM GOOD HOPE TO LUTSELK'E.



ARCTIC...THE ARCTIC LOW WILL TRACK TOWARDS NORTHERN BAFFIN ISLAND

TODAY, SPREADING LIGHT SNOW INTO THE REGION WITH IT. ACCUMULATIONS

WILL BE NEGLIGIBLE AS IT TRACKS SOUTH OVER THE ISLAND.



FURTHER SOUTH, A WEAK LOW TRACKING ALONG THE 60TH PARALLEL WILL

SPREAD SNOW ACROSS NUNAVUT MONDAY NIGHT INTO TUESDAY. THIS SYSTEM

WILL TAPER OFF BY TUESDAY EVENING, LEAVING BEHIND 2 TO 4 CM ACROSS

THE SOUTHERN KIVALLIQ.



AS THE SNOW TAPERS OFF IN THE KIVALLIQ, MODERATE NORTHERLY WINDS WILL

DEVELOP TOWARDS THE KIVALLIQ COAST, BRINGING A BRIEF PERIOD OF

BLOWING SNOW TO THE REGION. THE WINDS WILL BE TRANSIENT AND WE DON'T

HAVE ANY BLIZZARD CONCERNS FOR THE REGION.



AS THE ARCTIC LOW TRACKS EAST, A SURGE OF COLDER AIR WILL DIVE SOUTH

INTO THE EASTERN ARCTIC, SENDING DAYTIME HIGHS BACK INTO THE -30S ON

TUESDAY. COUPLED WITH WINDS OF 20 TO 40 KM/H, WIND CHILL VALUES WILL

DIP INTO THE -45 TO -50 RANGE.
