Spring sprang with a whinge as Ottawa awoke to a windchill of -18 Tuesday morning.
But warmer days are on the way.
By Tuesday afternoon, expect sunshine, a high of 0 C and a UV index – remember those? – of 3, or moderate.
The spring equinox – “equal night” – is when most of the world gets about 12 hours of day and night. Environment Canada explains that the equinox, which is at 12:15 p.m.Tuesday in Ottawa, is the moment when the sun passes directly above the equator with the result that day and night are the same lengths all over the world.http://ottawasun.com/news/local-news/weather-spring-officially-arrives-but-warmer-temps-will-take-a-while/wcm/c1d5ca76-71ac-4fa5-87cd-455614520b8b
