Windshield wiper effect?

Yup, the last 2 storms were misses by the models and in some cases really bad misses. And I wasn't saying that it's likely and I84 storm, just saying what the title reads.

Yeah next week isn't looking great. I'm not great at this stuff, so was wondering what others were seeing that I wasn't.

Wow, something must've shifted because here in Old Bridge, we have nothing. Light flakes, all wet outside, no coating at all. -

Posted by a met on another board named rb924119: All this talk about H5 and the latest NAM run, but nothing is being mentioned about the rest of the atmosphere??? Come on, my fellow snow-starved weather nut family, we’re better than this!! lol to me, the changes at H5 seem to be relatively minor compared to previous runs, but it’s what’s happening everywhere else that made the difference. Let’s work from the lower levels, upward, starting at the 850 hPa level. 850 hPa (and even further below): Notably stronger f-gen/isentropic forcing likely induced by enhanced low-level vortex tube stretching and associated cyclonic vorticity/curvature thanks to an anomalous westerly wind component coming across the Appalachians. We aren’t dealing with a regular trough here; it’s actually a lobe of the Tropospheric PV, which is highly anomalous at this latitude, and therefore, modeling has been under-representative of the effects that this will have on the atmosphere.This also goes for all levels above this as well. 700 hPa: similar to the changes seen at the 850 hPa level. 250 hPa: Notably stronger jet streak with our area located in the left exit region, which allows enhanced forcing for ascent. This is directly a result of the enhanced f-gen in the lower levels. All of these enhanced forcing mechanisms align, which resulted in the higher output. In my opinion, having only looked at this tonight, the enhanced solution would seem to fit the anomalousness of having a lobe of the tropospheric PV rotating overhead, and modeling being slow to pick up on that, and I would therefore not be surprised to see these trends continue across guidance over the next couple of runs. Carry on.
