I feel like that's a fairly common model bias. I don't know about the Canucks, but the GFS seems to do that regularly. I agree with your thinking vis-a-vis the Nam.
I believe I'm a few inches over 30" on the season, which means I've exceeded average climo for this area. The rest of the season is gravy, baby. Let's keep stacking it up.
Lol, ballpark of 17, give or take. Grains aren't really accumulating at this point. I'm surprised you're not higher. How much did you pick up in that first big band around lunch? I pulled almost 4" between 12:30 and 1:30.
I guess the idea is it takes a great deal of good juju to pull a 3 foot monster with hurricane force gusts and drifts to the rooftops, especially on the Cape. Thus he used up his juju and he's still paying for it via regression.
