At 7 am, Washington, DC had picked up 4.3" snow. That is Washington, DC's biggest snowstorm since January 22-23, 2016 when 17.8" fell. The 4.3" snowfall brings Washington's seasonal snowfall to 5.7". As a result, winter 2018-19 now ranks as Washington's 118th snowiest winter on record. Prior to the ongoing storm, winter 2018-19 was that city's 133rd snowiest winter. By the time the storm ends, Washington, DC will likely have its snowiest winter since 2015-16 when 22.2" snow fell. Last winter, only 7.8" snow was recorded and only 3.4" fell during winter 2016-17.

But not for this storm. It shows the strength of the confluence to the north. Typically, when Washington picks up 6" or more, PHL does much better than what the NAM showed. Hopefully, the NAM's idea will verify, as the DC region has not had much snowfall during the past two prior winters.

The 12z NAM shows an unusual distribution of snowfall centered around Washington, DC (where I believe 3"-6" is likely with locally higher amounts). The NAM shows 10" or more snow at DCA, less than 3" at Philadelphia, and no snow at New York City (where I believe no measurable snow will be reported). The only storm since 1950 that had 8" or more at DCA, <3" at PHL, and no snow at New York City occurred on March 9-10, 1999. Accumulations during that storm were: Baltimore: 4.6" New York City: None Philadelphia: 0.1" Richmond: 0.8" Salisbury: 5.4" Sterling: 8.9" Washington, DC: 8.4"

That's correct.

And if there's no more snow this winter (extremely unlikely), Winter 2018-19 would be Richmond's 59th snowiest on record.

Richmond picked up 11.5" snow. All of last winter saw 12.4" snow fall at Richmond. Since 2000-2001, only 6 winters have had more snowfall than winter 2018-19. Overall, winter 2018-19 now ranks as Richmond's 59th snowiest. Since snowfall measurements were commenced, 8/21 (7%) of winters saw 30" or more snow. However, 2/7 (29%) of winters that had 10" or more snow through December wound up with 30" or more snow. 4/7 (57%) picked up 20" or more vs. 26/121 (21%) overall. In short, Richmond may be on track for a very snowy winter.

It was a fantastic storm; the 2nd biggest December snowstorm on record.

With 1.01" precipitation through 6:40 pm, Richmond's total storm total snowfall is likely between 11.0" and 12.0" assuming similar ratios to what had been achieved through 5 pm. With the 9.0" as of 5 pm, winter 2018-19 is already Richmond's 71st snowiest on record (if it does not snow again). With 11.0", winter 2018-19 would rank as Richmond's 61st snowiest on record.

It was an exciting storm and it was great to see RIC get into the heavy snow.

Most of the guidance had far lower amounts for Richmond. Occasionally, a storm will bring its heavy snowfall 25-50 miles farther north than modeled. That can make the difference between a few inches or a significant snowfall.

Today's storm was a milestone event for Richmond. Through 6 pm, Richmond had received 0.90" precipitation. That brought 2018's total precipitation to 61.33", which surpassed the 61.31" that fell in 1975 to become Richmond's 3rd wettest year on record. In addition, Richmond had received 9.0" snow through 5 pm. That smashed the daily record of 1.8", which was set in 1988. That snowfall also ranks as both the 2nd highest daily snowfall up to December 15 and the 2nd biggest snowstorm up to December 15. With additional snow having fallen since then, Richmond could be in line to have both its highest daily snowfall and biggest total snowfall up to December 15. The records up to December 15 are: Daily record: 9.4", December 12, 1917 Biggest snowstorm: 9.9", December 12-13, 1917 Finally, this snowstorm has the potential to become the 2nd largest daily snowfall and 2nd biggest snowfall for December. Those records are 15.0" from December 22, 1908 and 17.2" from December 22-23, 1908.

Here it is:

The guidance for the most part has been remarkably consistent. I didn’t run numbers for Roanoke earlier, so I don’t know whether much would have changed had I made an estimate for there yesterday.

At 3:30 pm, light snow was falling at Asheville. Light rain was also being reported at Wilmington, NC where 2018's annual precipitation record was extended to 95.96". Meanwhile, heavy rain had moved into Pensacola. Overall, the major storm that had been the focus of the computer guidance for more than a week is getting underway. Parts of North Carolina and extreme southwestern Virginia will likely pick up a significant early-season snowfall, even when sleet, freezing rain, and even rain are considered. My final snowfall estimates for select cities are below:

As of 9:30 am, Atlanta had picked up 0.22" rain. That brings 2018's total precipitation to 60.08". 2018 is only the 18th year on record that Atlanta has had 60" or more precipitation. 2018 now ranks as Atlanta's 17th wettest year on record, just ahead of 1994 when 60.02" precipitation was recorded.

So far, from a quick look at the overnight guidance and the advance of the precipitation, everything seems remarkably on track for the storm.

The numbers I posted are below:

For a hint of what may lie ahead in terms of incredible moisture, as of 9 pm CST, here are a few precipitation totals in Texas: Houston: 2.55" (heavy rain was still falling) Huntsville: 3.79" (heavy rain was still falling) Palacios: 3.42"

Yes. I'll revisit the numbers and possible rankings ahead of the next storm.

While the coming snow is the major story for parts of the Southeast, the storm is also likely to dump a widespread 1"-3" precipitation. As a result, 2018 could rank among the 15 wettest years on record in numerous cities in the region. Already, Wilmington, NC has had its wettest year on record, by far. The 95.83" precipitation that has fallen this year has easily surpassing the previous record of 83.65", which was set way back in 1877.

Good luck with the move.

Summer turned hot in August in New York and the early fall in the eastern U.S. was much warmer than normal. Hopefully, there will be some opportunities this winter for some good snowfall where you are.

5".

That makes two of us watching from afar, though you are much farther away. Is it still unseasonably warm out in western Europe?
