Today's pretty sunny and currently -5, and so not as cold and windy as yesterday. The windchill was still bad until this morning, but it's dropped to -9 now.

Watch out, because March can still come up with surprisingly nasty cold snaps in Edmonton!
It's been known to drop as low as -42.7°C for a March record low at the international airport (YEG), which was on March 10, 2009. The weather station at City Centre Airport (YXD) has recorded as low as -36.1 in March, 1939, but came close to that record on March 8, 2003 at -34.0. in fact, that was the lowest recorded for all of 2003. To have the coldest temperature of the year in March is very rare here in Edmonton, or anywhere else in most of Alberta for that matter.
But on the bright side...YXD has recorded as high as 23.9°C for a highest recorded temp in March on the 30th in 2004, while YEG recorded its March highest at 24.2 on that same day in 2004.
In fact, March 30th is probably the earliest 20°C + high recorded for for both of these locations, yet even earlier occurrences of 20°C or higher in March have been recorded elsewhere in Edmonton itself prior to 1938 (Wx records at YXD didn't begin until October, 1937, so they were probably in or near downtown prior to that year). In that regard, the earliest I could find was on March 22, 1910, when a high of 20.0 was recorded.
In a nutshell, March can be a highly variable month in Edmonton temperature-wise. Just like winters in Alberta in general. Most years, though, you'll usually see the maximum for the month in the 5-15°C range. The first occurrence of 20°C or higher in Edmonton usually occurs in late April, and sometimes as late as mid/late May.
The winter snow cover is usually 100% gone by around mid-April, although I've seen it disappear before the end of March and as late as the last week of April. Of course, it's a given that snowstorms dumping up to at least 5 cm or more can occur after the winter snow cover has gone - you got to remember this is Alberta!
