SIGNIFICANT WEATHER DISCUSSION ISSUED BY THE PRAIRIE AND ARCTIC STORM
PREDICTION CENTRE OF ENVIRONMENT CANADA AT 7:00 AM CDT SATURDAY APRIL
25 2026.
ALERTS IN EFFECT...NONE.
SYNOPTIC OVERVIEW...THE 00Z UPPER ANALYSES REVEALED A LOW, NOW
FILLING, OVER THE PRAIRIES WITH RIDGES TO THE EAST, OVER HUDSON BAY,
AND TO THE WEST, OVER THE EASTERN PACIFIC.
THE SURFACE ANALYSIS SHOWS A WEAKENING LOW OVER CENTRAL SASKATCHEWAN
AND FAIRLY STRONG HIGH PRESSURE OVER THE EASTERN ARCTIC.
DISCUSSION...
PRAIRIES...THE SYSTEM THAT SMACKED THE PRAIRIES OVER THE LAST FEW
DAYS IS FINALLY WINDING DOWN. SNOWFALL IS GETTING LIGHTER AND WINDS
ARE WEAKENING, SO THE WINTER STORM, BLIZZARD, SNOWFALL, AND BLOWING
SNOW WARNINGS HAVE ENDED. SOME CONVECTIVE ELEMENTS CLOSE TO THE LOW
MAY CREATE SOME RATHER HEAVY BURSTS OF SNOW, BUT BY AND LARGE THE
SNOWFALL SHOULD STAY SUBSEVERE. AS WELL, SINCE THE LOW IS FILLING,
THE WINDS ARE WEAKENING.
NWT...WAVE MOVING NORTHEAST OVER ALASKA WILL BRING SOME MIXED PRECIP
TO THE MACKENZIE DELTA TONIGHT WITH A RISK OF FREEZING RAIN AT
TUKTOYAKTUK
NUNAVUT...SOME BLOWING SNOW IS ON TAP ALONG THE KIVALLIQ COAST AS THE
LOW LIFTS NORTHEAST FROM THE PRAIRIES, BUT AS IT'S APRIL, THE SNOW
WILL BE FAIRLY WET AND THE WIND WON'T BE FROM A FAVOURED DIRECTION,
SO BLIZZARDS ARE UNLIKELY HERE..
