SK AND SOUTHERN MB. SOME LINGERING FLURRIES IN THESE AREAS WILL
DECREASE THROUGH THE MORNING. THERE ARE STILL BULLETINS IN EFFECT AND
HEAVY SNOW OCCURING IN NORTHERN MANITOBA, HOWEVER, CONDITIONS IN
THESE REGIONS WILL BEGIN TO IMPROVE THIS AFTERNOON/EVENING.
ON THE BACKSIDE OF THE LOW, THE STRONG WINDS THAT DEVELOPED OVER
SOUTHERN MANITIOBA WILL EASE THIS MORNING AS THE LOW CONTINUES TO
PULL OFF TO THE NORTHEAST.
SURFACE HIGH PRESSURE WILL BUILD IN THE WAKE OF THIS SYSTEM.
NT...GUSTY WINDS AND SNOW CONTINUE FOR COASTAL PORTIONS OF THE NWT,
PARTICULARLY AROUND ULUHAKTOK AND SACHS HARBOUR WHERE A FEW CM OF
SNOW COMBINED WITH GUSTS UP TO 60-70 KM/H WILL RESULT IN A VERY
BLUSTERY DAY.

ACCUMULATIONS. AS THIS LOW PASSES OVER BAFFIN ISLAND TO BAFFIN BAY,
CLYDE RIVER WILL SEE GUSTY TO STRONG SOUTHWEST WINDS. THESE WINDS
SHOULD STAY SUBWARNING, BUT WILL BEAR WATCHING.
