REST OF TONIGHT...THE NEXT DISTURBANCE IS DROPPING SOUTH ACROSS
B.C. AND THE LEADING CLOUDS ARE INFILTRATING THE NORTHERN ZONES.
THIS WILL BRING IN THE FLURRY THREAT OVERNIGHT TOO. TEMPERATURES

CLOUDS COMING IN FROM THE NORTH THIS DROP IN TEMPERATURES SHOULD
SLOW OR REVERSE IN BRIEF INSTANCES. MINOR TWEAKS MADE TO OVERNIGHT
LOWS...ADJUSTING THEM DOWN A DEGREE OR TWO BASED ON CURRENT
TRENDS. IN GENERAL THOUGH THEY SHOULD COME WITHIN A FEW DEGREES OF
LAST NIGHT'S LOWS...AND EITHER WAY ARE STILL BITTERLY COLD FOR
THIS TIME OF THE YEAR. OTHER MINOR ADJUSTMENTS TO INCREASE CLOUD
COVER OVER THE NORTHERN ZONES BASED ON SATELLITE TRENDS. /JCOTE
