DISCUSSION...
AB...YESTERDAYS ALBERTA CLIPPER HAS EXITED THE REGION, LEAVING
GENERALLY NORTHWEST FLOW IN ITS WAKE. MODERATE STRONG WINDS ARE
EXPECTED AGAIN TODAY OVER SOUTHERN ALBERTA, WITH GUSTS UP TO 70 KM/H
IN THE FORECAST. FLURRIES WILL CONTINUE OVER THE ROCKIES, BUT NO
ACCUMULATIONS ARE EXPECTED. OTHERWISE NO SIGNIFICANT WEATHER
EXPECTED OVER THE NEXT 36 HOURS.
MB/SK...THE EAST-CENTRAL SASKATCHEWAN LOW WILL CONTINUE TO QUICKLY
TRACK EASTWARD TODAY, SPREADING INCLEMENT WEATHER THROUGH PARTS OF
SASKATCHEWAN AND MANITOBA. PRECIPITATION ASSOCIATED WITH THIS LOW
WILL PRIMARILY FALL AS RAIN WITH A NARROW BAND OF 10 TO 20 MM
FORECAST THROUGH CENTRAL MANITOBA TODAY WITH SCATTERED SHOWERS
FORECAST THROUGH THE SOUTH.
BUT THE MAIN CONCERN WITH THIS LOW CONTINUES TO BE WIND. ALTHOUGH
SEVERE WINDS FAILED TO MATERIALIZE IN WESTERN SASKATCHEWAN SATURDAY
EVENING, THERE IS HIGHER CONFIDENCE FOR THE DEVELOPMENT OF SEVERE
WINDS OVER WESTERN MANITOBA AND THE RED RIVER VALLEY SUNDAY
AFTERNOON. THE INCREASED CONFIDENCE IS A RESULT OF TIMING, WITH
SEVERE WINDS OCCURING DURING DAYLIGHT HOURS, MORE FAVOURABLE
TERRAIN, AND AN OVERALL BETTER DEVELOPED GRADIENT WITH THE LOW OFF
TO THE NORTH.
WESTERN ARCTIC...LOW NEAR KUGLUKTUK CONTINUES TO BRING SNOW AND
STRONG WINDS TO NORTHERN COASTAL COMMUNITIES AND THE MACKENZIE
DELTA. BLIZZARD WARNINGS HAVE BEEN ENDED AT SACHS HARBOUR AND
ULUKHAKTOK THIS MORNING AS WINDS WEAKENED. HOWEVER, A BLIZZARD
WARNING HAS BEEN ISSUED FOR CAMBRIDGE BAY, WHERE VISIBILITY IS
EXPECTED TO DETERIORATE EARLY MONDAY MORNING. FRESH SNOW WILL FALL
TODAY AND TONIGHT, AND STRONG NORTH WINDS GUSTING TO 80 KM/H WILL
DEVELOP BEFORE MORNING. THE BLIZZARD IS EXPECTED TO LAST UNTIL
MONDAY EVENING.
PERSISTANT SNOW WILL ACCUMULATE IN THE MACKENZIE DELTA, WITH ANOTHER
4-6 CM OF SNOW EXPECTED.
FOG FORMED OVERNIGHT IN THE NORTH SLAVE REGION, AND IS EXPECTED TO
LAST UNTIL ROUGHLY NOON TODAY. A FOG ADVISORY WAS ISSUED.
EASTERN ARCTIC...TODAY, THE LOW NEAR KUGLUKTUK WILL CONTINUE TO
SPREAD PRECIPITATION THROUGH KIVALLIQ. A RAIN/SNOW MIX IS FORECAST
ALONG THE COAST, WITH SNOW FOR BAKER LAKE AND NORTHERN KIVALLIQ WITH
A COUPLE CM ACCUMULATION POSSIBLE.
