Plus I think it’s been discussed here before that they try to keep their message to the general public consistent. Conspiracy theorists like me think there’s some sort of bureaucratic quality control where forecasters get dinged if they have to constantly downgrade and upgrade warnings/advisories, but that may be a stretch.
Perfect, really. The snow came in early enough and hung on long enough that even those of us who slept got to enjoy seeing it fall on both ends of the storm.
Awesome finish to winter. Overperformed massively and left no doubt as to its status as a warning level snow. Best March storm in recent memory and I’d probably even rank it ahead of 2018 even if the total won’t be as high.
The only thing I can think of that would make the airport significantly higher than the city’s totals in this case is UHI. There is a lot of sun today and a transition from very warm to cold, with the bulk of the snow falling early in that transition period.
18z long range HRRR that shows the whole storm I would guess should look better than 12z. The last few hourly runs have trended up through hour 18.
Edit: it’s keeping hope alive for a high end advisory event.
HRRR puts down a solid 5”, with some areas of the county exceeding 6” in places that see the lake enhanced bands in NW flow (which the NWS admits may be overdone).
So let’s say it’s 4”. Will it survive the sun angle of a mostly cloudy mid-March day with temperatures in the low 20s, or will it be gone before sunset?
Not convinced we’re getting 4 either but it is what it is. On to thunderstorm season, then months of it being 88 and miserably humid while Syracuse gets to 95.
I think his comments make sense. If we get 2-4” we finish the winter with a total in the 30s, while if we get nothing we can still finish the winter with a total in the 20s which gives him more of an avenue to complain about how horrible this winter was.
It’s not the watch that is perplexing. It’s more the fact that the forecast snow map actually increased from 5.3” to 6.4” in Pittsburgh despite the fact that the models seem to have gone the other way in the time between the issuances of those two maps.
NWS official forecast is up to 5.3” but that will surely go down if the models, especially the NAM, are onto something. The 6z was a complete disaster (if you can actually reasonably apply words like “disaster” to not getting much snow).
