Temperatures to plummet...

An Arctic front is on our doorstep this morning. The front just to the west of Ottawa at 7am will dive south and east across the forecast district today with temperatures dropping to -25 by Tuesday morning, and winds increasing. About 5cm of snow will accompany the front in heavy bursts along with 70km/h winds. The winds will persist into the evening producing cold windchill values and blowing snow. If travelling today be prepared for changeable weather. A Winter Storm Warning is in effect for the mountains across New York and Vermont. Lake Effect Snow Advisories are posted for the lee of the lakes. Windchill Advisories are also posted for southwest Ontario including the GTA.
