When will the snow and ice finally melt?

It snowed again last night and local schools cancelled classes again. 

Snow on February 17th is not unusual.  What has been unusual is the amount of snow that has fallen across the United States this Winter and the cold temperatures that have persisted across much of the country.  Many cities are experiencing some of their highest snowfall amounts on record and some of their coldest temperatures on record.  This means that much of the snow that has fallen since the beginning of December remains on the ground - we have not had our typical cycle of repeated snowfall followed by melting. 

This presents an interesting question. 

When will the last snow and ice melt this Spring?

My last photos of snow and ice from the Spring of 2013 dates to April 23rd.

Unless we have an unusually warm Spring, I expect that I may be able to find some remaining ice as late as May 1st.  I guess I will have to wait and see.
