Wet spring and active weather all month long

It has been a very wet spring. I measure rain in my rain gauge just about every morning. Since the beginning of April, I have measured 4.81 inches in Provo. There is actually a little little more because I accidentally spilled the water out of the gauge before I got a measurement.

At my Davis weather station in Spanish Fork, I have measured 4.44 inches since June 1st. (Had to get this info from Weather Underground because WeatherLink doesn't let me see this anymore without paying for my own data I send to them; just a little upset).

Why so much rain this year? I remember in my synoptic meteorology learning that the more wave numbers you have the more active and progressive systems are. We definitely have a high wave number in the northern hemisphere, 6+, and that means storms roll through quickly. Maybe I should dust off my synoptic meteorology notes and get a refresher on this. I'm very rusty.
