My lilac tree is…blooming?

My lilac tree is…blooming?

I'm in zone 6 (seattle, wa). I looked out the other day, and my lilac tree had two different flower blooms on it - like the regular spray of blooms that come in the spring. Is this normal?! The tree is losing leaves AND blooming? Is it sick? Should I cut the blooms off? The weather has not been warm - it's been highs in the 50s F and lows in the 30s F with frost some mornings.
Yay yay yay! Butterflies!

Yay yay yay! Butterflies!

It is a travesty!!!
