RIC Airport

From what we've seen over the years, they come out of their hiding when it actually does snow. Haha.

You're in the AKQ CWA so you're cool. ;-)

I've been posting on these boards for many years going back nearly 15 years now. As I've said previously, from a climate standpoint, particularly when we consider snowfall climatology, we do not belong in the SE thread. I would argue, especially for the Richmond area, that there is a higher correlation with DC than Raleigh. The winter of 2007-8 was the first time I created a thread for us and I contemplated including Hampton Roads because often times there is a big disparity with snow between the two regions. Think of two weeks ago and numerous other examples. But, since I wanted to generate more posters I felt compelled to include the two metro areas. This is a DC centric forum. That is the whole point of this thread so that we had a place to escape and focus on our unique area. But, if people post in the other threads or quitely lurk without contributing here, then this idea becomes meaningless.

Radar has really blossomed last hour or so.

Airport is back to ALL snow as of 7pm ob. Snowdepth was 1 inch.

Mesoscale Discussion 1789 NWS Storm Prediction Center Norman OK 0152 PM CST Fri Dec 08 2017 Areas affected...Parts of southern/eastern Virginia into the Delmarva Peninsula Concerning...Heavy snow Valid 081952Z - 090045Z SUMMARY...Heavy snow rates around or in excess of 1 inch per hour could develop and impact Richmond and surrounding areas of southern and eastern Virginia by early evening. This could commence as early as 5 PM EST and continue through the 8-9 PM EST time frame. DISCUSSION...Strengthening large-scale ascent is contributing to increasingly saturated thermodynamic profiles and precipitation rates across much of southern through eastern Virginia. This appears likely to be aided by a zone of enhanced lift associated with mid-level frontogenetic forcing, which is forecast to redevelop northeast of the central Appalachians through the northern Mid Atlantic Coast region by early this evening. This is expected to increase lift through the favorable mixed-phase layer for large dendritic ice crystal growth, which could potentially provide support for heavy snow rates. Generally west through north of the Hampton Roads area, roughly from near Danville through much of the Greater Richmond area, northeastward into the Delmarva Peninsula, models suggest that temperature profiles are generally below freezing. Current surface temperatures/wet-bulb temperatures appear marginal for snow reaching the surface. However, with the onset of nightfall, and perhaps weak low-level cold advection and cooling associated with melting precipitation, a changeover to snow appears possible by the 22-23z time frame, if not before. Heavy snow rates around or in excess of 1 inch per hour appear possible, and may continue into the 01-03Z time frame, before diminishing. ..Kerr.. 12/08/2017 ...Please see www.spc.noaa.gov for graphic product...

It's too bad that the advertised pattern isn't happening a month later. Below are the measurable snowfall events since 1897 for the first 20 days of December. Definitely doesn't bode well if we are looking for a large event. Plus, there hasn't been any measurable December events since 2010.

Looks like there is an issue with the Richmond ASOS. You can see the sporadic temperature readings shortly after midnight. Take note, in particular, the intrahour obs. http://www.wrh.noaa.gov/mesowest/getobext.php?wfo=sew&sid=kric&num=60&banner=on The CLI that was sent showed RIC hitting 75 degrees today, but clearly that is incorrect.

Time for a new winter thread and lets hope there will be plenty to talk about. By the way, for the first 11 days of November, only three other days had high temperatures colder than yesterday at Richmond. Those days were 11/11/1987 (36°F), 11/6/1953 (38°F) and 11/11/1913 (41°F). Interestingly, the first two occurred on dates with two of the largest November snowfalls at RIC.

7" officially at RIC. We got dry slotted so although we didn't get the HUGE totals, still a decent event, particuarly when you consider about 6" was still leftover on the ground from the storm a week earlier.
