15th November 2010 - Monday

High: 7.5
Low: 0.5
Rain: (0)
Snow: (2)
Days we didn't see any sun: (2)
Days swept snow from drive: (0)
Days shovelled snow from drive: (0)

It was a fairly pleasant start at +3. There was a fair bit of cloud, but that was beginning to clear by mid-morning and we had quite clear blue sky by noon.  Temperatures reached around +7 and it was quite nice in the sunshine, but quite cold out of it. 

It started to sleet at around 10pm and it quickly turned into snow.  It got quite heavy and looked to be set in for the night.

There is a weather warning in place for: Airdrie, Cochrane, Olds & Sundre


10 to 15 cm of snow expected tonight into Tuesday morning.


An Alberta clipper is forecast to develop near Calgary tonight tracking southeastwards into Nebraska by Tuesday evening. Snow will develop along the northern foothills this evening spreading southeastwards to the Cypress Hills overnight. Snowfall amounts along the foothills are expected to be near 10 to 15 cm with up to 20 cm near the Cypress Hills. Strong northerly winds will develop behind the clipper with gusts to 70 km/h over Southeastern Alberta. These winds will combine with falling snow to give reduce visibilities in blowing snow. Heaviest snow will taper off Tuesday morning for the foothills and Tuesday afternoon over the Cypress Hills.


The system is currently developing over the gulf of Alaska and will move into Alberta this evening. Given the rapid motion of the system there is still some uncertainty to the storm track. The regions of Calgary, Drumheller and Claresholm are currently expected to see 5 to 10 cm of snow. As the system approaches through the day snow fall amounts will be further refined and warnings may be adjusted based on updated storm tracks.
