How long might the rise of right populism in Europe continue?

Many political parties that might be considered as right populist/nationalist parties have been gaining more traction in the EU, like AfD, Finns Party, NF, Fidez, etc. on generally anti-immigration and eurosceptic ideas. Will this trend continue as long as the migrant crisis exists, and might it continue afterwards? And what long-term effects might we see as a result of the change in political climate?
