Yep Grit, spot on. Duration is what we want to maximize. Dont have to have the full throttle effect to score the white stuff. The longer we can keep window open with just beyond the threshold cold, the better our chances. The Max time we've been making it between qpf events is about 5 days. So if you can create a 7 to 8 day window of opportunity with Cold air in pkace, then odds are in our favor. The 3 day artic blast thats in and out want get it done, even though it looks more impressive on the thermometer. Im more interested in what the ruler shows.
