I've been thinking about the seasonal lag thing too lately. Sure feels like we can chalk up another one in favor. Keeping it going. Let's see if we go hot and dry quickly or if spring gets drawn out. I have my suspicions.
Some quick research shows that since 2001, its exceeded 65 in March 10 times including 7 times over 70. Seems reasonable.
But, of the 8 years it didn't reach 65 in March, 5 of them happened in the last 6 years (13,14,15,17,18). Looks like '19 will likely also not break 65.
