using the 10th as a cutter to say that the pattern isn't great is disingenuous. that's been a cutter for like two weeks. the 13th does not look good at this latitude and hasn't for a while. the risk for anything larger is from the 15th to the 23rd or so, and the pattern still looks good for something
using ensemble snow means is not the best way to go about analyzing if a pattern is favorable or not
it's not certain that it won't cut... cutting during that timeframe around the 17th just isn't the favored outcome. suppression seems more likely than a cutter given that pattern
yeah, it’s once the block decays. Arctic airmass in place, decaying WB -NAO, AK ridge, TPV moving towards the 50/50 region, and PNA building. all the pieces are there
