I’m working on a side project to try and prove this out by using adjustments on daily temp and precip data at KIAD including SWE, to today’s climate to tease out whether a 15” storm in the 60s, 70s, or 80s would actually produce more today. I will also tease out, statistically, on how 2-4” events from the past would be affected in today’s climate.
Hopefully I’ll come up with the results this summer.
