..MARCH IS SET TO ROAR IN LIKE A LION AS ANOTHER SIGNIFICANT STORM
TAKES AIM ON SOUTHERN ONTARIO FOR THURSDAY..

A DEVELOPING LOW PRESSURE AREA OVER COLORADO WILL BEGIN TRACKING
ACROSS KANSAS ON WEDNESDAY AND TOWARDS WISCONSIN ON THURSDAY. THIS
WEATHER SYSTEM WILL TAP A SURGE OF WARM MOIST AIR FROM THE GULF OF
MEXICO WHICH WILL SET THE STAGE FOR AN APPRECIABLE WINTERY MIX OF
PRECIPITATION TO AFFECT THE GREAT LAKES BASIN.

IT WILL BEGIN WEDNESDAY NIGHT IN SOUTHWESTERN ONTARIO INITIALLY IN
THE FORM OF SNOW AND ICE PELLETS BUT QUICKLY CHANGE TO FREEZING
RAIN. THIS WEATHER TRANSITION WILL SPREAD ACROSS MUCH OF SOUTHERN
ONTARIO DURING THE DAY THURSDAY WITH A FEW CENTIMETRES OF SNOW AND
ICE PELLETS FOLLOWED BY A PERIOD OF FREEZING RAIN. THE FREEZING RAIN
WILL CHANGE TO RAIN IN SOUTHWESTERN ONTARIO TO NIAGARA BUT PERSIST
IN REGIONS EAST OF LAKE HURON AND AREAS NORTH OF LAKE ONTARIO.

THE GREATEST IMPACTS WITH THIS STORM ARE EXPECTED TO BE ANY TYPE OF
TRAVEL..DUE TO ICING AS WELL AS POOR ROAD CONDITIONS FROM DENSE SNOW
AND ICE PELLETS COMPOUNDED WITH FREEZING RAIN. STRONG EASTERLY WINDS
OF 40 TO 70 KM/H WILL MAGNIFY THE FREEZING RAIN PROBLEM SINCE ICE
ACCRETION ON TREES MAY BRING DOWN LIMBS AND SOME POWER LINES.

IN THE LONGER TERM..SIGNIFICANT AMOUNTS OF SNOW ARE LIKELY THURSDAY
NIGHT AND FRIDAY OVER PORTIONS OF SKI COUNTRY AND THE OTTAWA VALLEY.

THIS IS A POTENTIALLY SIGNIFICANT WINTER STORM WHICH WILL AFFECT A
BROAD CORRIDOR OF THE PROVINCE. ENVIRONMENT CANADA WILL MONITOR THIS
SITUATION CLOSELY AND WILL LIKELY ISSUE WATCHES OR WARNINGS ON
WEDNESDAY AS THE SITUATION DEVELOPS.
