Most of it will be gone probably by mid-April. Isolated pockets can be found in shady spots such as under spruces even in late May if the weather has been cool until then. Some large, artificial banks of compacted snow made by snow plows can take incredibly long to melt. I remember once seeing one on the side of a football field in early June when the air temperature was about 25 C. It felt strange to walk past one in shorts.
In Lielahti, Tampere, there is a place where the city dumps much of the snow collected from the streets of the city centre. That snow is quite dirty and cannot be dumped anywhere. Now, that dump contains a very large amount of snow. Often, it won't be gone until August.
It's going to take a good while before the snow is all gone :D maybe around two months, but it should start melting of a bit sometime soon :)
