Hurricane Agnes

Temp here now up to 36 with dp 28 and overcast. Sun hasn't made an appearance here as yet through the cloud deck. My low so far this morning was actually at midnight at 25. Half the snowpack is gone and lots of melting going on.

WWA tweaked to remove Philly, New Castle, DE & Mercer/Middlesex, NJ - When I pulled up the radar about 90 minutes ago, I was a bit surprised to see that it was generally void of precip, so it's moving slower than progged and is hitting that subsidence from the dry air. However it has moistened up gradually here overnight. My current 24 dp is like day and night compared to the 9 that got down to yesterday. Temp here is now up to 30 and there is a distinct deck of clouds overhead.

Non-diurnal trend continued overnight IMBY and I am now up to 29 with dp 23, with a deck of clouds overhead.

Probably whoever is left posting in the Tropical forum.

He has to "manage" the elves who are making all the toys all year and then train all the up and coming "Rudolphs" so they can light the way for the next generation. As a quick obs - The high just tapped 30 here (low was 19) and then dropped down to ~23 late this afternoon but is now on the rise again and is currently 25. The dp had dropped down to as low as 9 but has actually gone up and is now 16. There have been a few puffs of breeze but otherwise, with a clear sky, fresh snowpack, and not much wind, will see how it responds overnight or continues the non-diurnal rise.

I'm trying to remember but I think way back, one of the mods here had Heat Miser (maybe Rib?).

I didn't even recognize you! Around these parts, you would be swamped by a pile of these guys -

It's like blizzarding for 24 hours. Classic juicy Miller A from the GOM and up the coast.

Yeah... my dp is down to 10 at the moment although once the warm front lifts, I expect it to gradually moisten up.

And hopefully well above freezing by then although the ground and other surfaces are very cold. I left a windshield cover on my car (that I put on before this last event) just in case.

WWA coverage from Mt. Holly -

Honey Brook maybe?

The bottom dropped out overnight (at least for early January) and I had a low of 19 this morning. It's currently sunny and 21 with a dp of 10. Need to swap out my humidifier filters this morning (was due to put new ones in anyway) because the humidity in here is down to 25%.

That's not bad at all!! If it survives the wind, a little warmup. and whatever intensity of rain is forecast for Sunday, it could flash-freeze into a thick glacial base for any future frozen precip.

I don't think they were even forecasting it that low by that Saturday. I remember earlier in the week some 1" - 3" estimates but as we approached that weekend, the forecast had been gradually increasing until it was up to at least 3" - 5", then I think 6" - 8" by the Friday/Saturday timeframe. I watched the classic TWC coverage that weekend where TWC kept adding more and more colors to their snow map that Saturday, Sunday and Monday, literally doing "real-time" / "on the fly" nowcasts. Someone posted a video of TWC (a Wilmington feed which is within our CWA) with the current conditions/forecast late Saturday afternoon (where the Winter Storm Warnings were already up) - Someone else posted a Baltimore feed of TWC (Sterling CWA) with the same storm coverage but now picking it up from around 9 am Sunday, where the Blizzard Warnings were already up -

I calculated the snow water equivalent (at least down here in Philly) as 18:1 (doing a melt from what was collected in my Stratus). And with the wind, dry arctic air, and dews in the low teens or less (I'm currently down to a dp of 12), much of the snow pack has been blowing around, and that means sublimation can come into play (even with temps below freezing), literally "evaporating" the snow (i.e., the water goes right from solid to gas in the bright sun). I agree with the issues of scouring out that built-up cold air being a tall order. Will have to see how much of a warm nose happens Sunday (and where in the atmosphere it oozes in).

With the sun having set, the temps and dps are dropping and I'm currently down to 26 with dp 14. It has still been breezy though so if that continues through the night, even if lightly, then may not get ideal radiational cooling.

Until the power goes out. I'm a bit concerned about the antecedent cold leading into Sunday and any initial precipitation freezing everywhere on contact before it starts melting and warming surfaces. The powdery snow down here may be mostly dissolved away depending on what happens tomorrow for a high and with any initial rain onset Sunday. I have a "Polarshield" cover thingy on my car windshield right now that I will probably leave on through that event.

Mt. Holly tweeted out a cool sat picture of the aftermath. You can even see some of the "snow holes".

MJO progged (by GFS and its ensembles) to (at least briefly) get into Phase 8 around that time).

The Profile offers a field to include a "Location" and literally everyone in this thread (other than one person who did an obs from wherever they were) has something in there except you. I just got in from clearing the snow off my SUV (big job thankfully handled very well with the use of a big new Christmas present - an extendable 60" snow broom/brush/scraper that did a good job clearing the lightweight snow). Lots of powder blowing around out there and am still warming the poor fingers (the isontoner gloves are good for driving but probably needed something warmer for what I just did). Currently changeable skies and still holding at 29 but dp continues to drop and is bopping between 18 and 19.

From the 11:02 am PNS - Will have to see if the Freehold spotters have any additional measurements to report in the next publication since it would have still been going there at the listed times (West Freehold is SE of Freehold).

I had posted this in obs but re-posting here on the SWE calculated from the Stratus gauge collected snow -
