It is significant even with the fact that it is warping into an elongated low so it could appear north quickly on a panel. Look at the precip shield below. 12Z first, 17Z second. Snow is farther south and the rain in S VA is mixed with snow due to the lesser push of warm air.
That was why I added the ending...looks great but it is the srefs meaning I would not use it to adjust my forecast. Lot's of uncommonly used meso's in there. Wrf's, etc...
Well, the 3K was way below on snow totals for the LSV which is what I was referring to. Nam 12 was about 1" below the higher totals to our East. Nam 12 was surely acceptable but I am a bit surprised most runs after the Nam were 1-3.
GFS transfers to the SE Coast quite early and the resulting SLP remains fairly week as it traverses Northeast fairly far off shore....snow map below but a note of caution with this one is that it requires the coastal influence to get these levels in SC and East PA. Technically there is no snow in those areas when the lowest level of pressure moves offshore. Would probably be some snow with the 500 pass but probably not this much if the coastal scoots faster. Miller B fun.
Yep, it is strange but the deep blues were suggestive of more.....about 1" less than the HRRR where the HRRR showed higher areas in the LSV. Snow all the way down to shortpump. Generally, 2-4" for most of S Central PA.
@Chris78 the HRRR was close to giving us the best snows....if it has delayed elongating/transfer another hour or two we get near 4" I think. As it is we do get dry slotted compared to those east of us.
