The official H/L yesterday at GRR was 24/20 there was a trace of snowfall the day started with just 1” on the ground. The sun did appear and was out 33% of the time. For today the average H/L is 32/20, the record high of 63 was in 2008 the coldest high of 4 was in 1942 and 1912. The record low of -15 was in 1988 the warmest low of 58 was in 2008. The wettest was in 1907 with 0.59” the most snowfall of 5.4” was in 1962 the most on the ground was 20” in 1999.

Hmmm I feel like those members above -5C beg to differ. They are likely deamplified and progressive thus kind of blowing up the pattern .Edit: ok nvm I see what you’re saying.

It still looks like we are going into a -PNA. I keep saying, it's still to far out to get exact details on what's going to happen so we need to just keep watching the models play out

850s plume in the LR is an _actual crapshoot_

Big waffle back on the GEFS. But you have to acknowledge, this is still a pretty stout -PNA signal at 12+ days out. Something I've noticed with the waffling today. Hardly any ensemble means outright cancel the pattern change. I think the main issue is how amplified the wavetrain gets based on the strength of the Scandinavian high in the 6-10 day range. The run to run waffling is probably due to some inflection point in the mid-long range that Phil could educate us about; but whatever it is, that timeframe is important. Notably, for days consecutively now, the ensemble mean has advertised AK ridging around 1/20. What we've been stressing out about is the strength of that still existing signal that never left. I think we'll be okay, so long as the fundamental structure of the pattern doesn't collapse into more of a progressive nature in the ensemble means, like what we saw in December. What we might be seeing here is a poorly handled low or shortwave in the Atlantic ahead of the Scandi ridge, or some polar lobe shenanigans.
