The pattern is definitely changing and spring is on the way to Fairbanks-land this week.
Here's a plot of daily snow depth here on Keystone Ridge for each spring the past 17 years. I've highlighted some of the notable years.
So what will the date of meltout* be this spring on Keystone Ridge? I'll go for 24 May, assuming a curve somewhere between the rapid decline in 2002 and the much slower rate in 2000, but note it's never a quasi-linear decline to zero: once the snow depth gets down to 10-12", it goes fast.
*Meltout is defined here as the date when the snow depth fall to zero or trace. In practice, this means the date when the snow-free area in the vicinity of the weather station increases to greater than 50 percent coverage.
