Hurricane Agnes

View from KDOX.

It runs every hour so if you don't like a run, wait for the next one. Currently 30 here with dp 29 and colder parts of the streets are starting to cave. Despite the marginal surface temps, the snow is actually fine and would be about SN level. It's interesting that the current band that goes back to about Lancaster County, has been basically sitting over the area from there to the coast for the past 5 hours or so. I do see a R/S line not far off the coast though so not sure what will happen with that.

Currently getting some variable SN- to SN from a band that has been overhead and had a heavier return (attached in this post) that moved through briefly and added a coating back to the bare cars and colder/untreated surfaces where there was snow melt/evaporation. It is below freezing now at 31 with dp 28.

I have been talking about the "dance of the lows" the past couple days. And the models were depicting the do si do and other dance moves up the coast.

Ahh okay... missed that. As an obs, currently 32 with dp 28 and except for grassy/mulched areas, the 0.5" of snow that I got from round 1 (PRE) is gone. Am attaching the 18z 3k NAM.

IMHO a 4" - 8" (W --> E) in the I-95 corridor might still be a good call although I think Mt. Holly gave it a wider range initially - 4 - 11".

Just hitting 32 now with dp 29 and the higher dbz band just went poof as it moved to the NE of me. So the melting of what I got so far has commenced while the sky is getting brighter (although no sun at this point).

Latest tweet from Mt. Holly -

Am in a pixie dust pause at the moment, so nothing being added to my 0.5". However a little band with some heavier returns appears to be headed this way so will see what happens. Currently 31 with dp 28. I actually have some melt that tipped the bucket in my station for 0.01" (have the Stratus out with funnel and inner tube removed to collect whatever it captures to do a SWE if I'm up to it).

The "stall" is that other low and the "low dance"!

For the past week, the models have briefly shown some low scooting off the southern Florida coast and then "disappearing" while a new low forms off the coast of the Carolinas. As time went on, the Florida low would make "an appearance" and then the 2 lows seemed to be doing a waltz, the two cheek to cheek and jowl to jowl, while each one seemingly wanted to "take the lead" and yank the other in the opposite direction (either to the east or to the west) in the models, as they crawled up the coast. Sorry for my wild description but when you animate the runs, the "low(s)" just jump(s) around east/west/east/west wildly. As an obs, I am currently 30 with SN and dp 27. Looks like I have about 1/2" so far but there seems to be some insolation going on because there is some melting/evaporation despite the temps being below freezing. The wind is pretty light too so far so it's not blowing around.

You are welcome and here is the 3K NAM!

Obs of PRE - currently SN- but slightly bigger flakes and temp 28/dp 24. Have a light coating now including on grassy surfaces (although the grass is still clearly visible).

12z NAM looks tucked early on.

Thank you. 12z NAM is running so will post something once more panels are up.

Whatever that is, it has been causing the continual "west - east - west" model dance, depending on how much "weight" they put on that. The GFS seemed to have ignored it early on but has drunk the koolaid and is now having to deal with it, whereas the NAM and Euro completely embraced the chaos early on. This also impacts whether you end up with a SECS whiff or a HECS.

Current obs - temp 29 with dp 23 and SN-. Have a dusting on the colder/non-treated surfaces.

6z GFS and a later wild panel with that damn "ball and chain other low".

I am just posting model images for the benefit of this subforum for people to look at since there are those who lurk here who are watching the play by plays and who have expressed a desire to "learn". I have given no weight or "analysis" of which one(s) I think is "correct". They all constitute "data points", nothing more, nothing less.

Looks like you work where hazwoper lives.

And just checked since the returns have come overhead and there be very fine snowflakes - more than flurries but still light.

Last Ukie run (0z).

Right on the city doorstep!
