RIC Airport Posted January 14 Author Share Posted January 14 13 hours ago, RIC Airport said: Although there haven’t been any major storms, these light snow events combined with cold temperatures have made January 2025 the best stretch of winter in years. For the first time since the 2016 blizzard, Richmond has officially recorded seven consecutive days with a snow depth of 1 inch or more. Snow depth is measured daily at 7 a.m. (12z), and the recorded depth goes for that calendar date, even if the snow melts later in the day. You can see the 12z daily snow depth in the first attachment below. January 5th has a 0 snow depth because the snow did not begin until later in the evening. The next attachment below shows Richmond's longest snow cover stretches from 2000 to 2025. Two back-to-back snowstorms helped make January 2025 have one of the most consistent snow cover periods over the last 25 years. Notice that the snowy winter of 2009-10 had 1 inch + snow cover lasting 14 days (16 days if you include trace amounts). The record for Richmond is 21 days from the winter of 1947-48. Furthermore, the first 12 days of this month rank among the top 20 coldest first 12 days of January since records began in 1897. With the continued cold temperatures projected over the next two weeks, this January has the potential to be the coldest since at least 1988. So far this month, Richmond has received 6.5 inches of snow. To rank among the top 10 snowiest Januarys, an additional 8 inches of snow would be needed by the end of the month. January 2025 is off to a great start and hopefully we can score in a big way before things are all done, we are due for a 20"+ season. 12 hours ago, Conway7305 said: This is good info. Thanks RIC! All we need is a clean Miller A and we are set Here's an update! Yesterday morning, the snow depth measured at 12z was 2 inches, bringing the total duration of snow cover to 8 days. This is the longest period of at least 1 inch of snow cover in Richmond since the winter of 2009-2010. Considering that the temperature at RIC reached 51°F yesterday, it is likely that this stretch of snow cover has ended after 8 days. However, a trace of snow may have still been recorded on the ground this morning. We'll see what the CF6 says tomorrow for this morning's measurement. According to the snow measurement guidelines. "When in your judgment, less than 50 percent of the exposed ground is covered by snow, even though the covered areas have a significant depth, the snow depth should be recorded as a trace (T). When no snow or ice is on the ground in exposed areas (snow may be present in surrounding forested or otherwise protected areas), record a "0".

RIC Airport Posted January 14 Author Share Posted January 14 The only storm that comes to mind delivering anything close to this outcome is the February 12-13, 2014 storm. That's why when you don't have a bona fide high up north and you're relying on just an antecedent airmass, you're bound to have precipitation issues in an EPO-driven pattern. This airmass is colder than that storm, so we may get more snow, but mixing may be inevitable even with a track like this, especially along and east of US 15. Obviously, things will change. There is no need to go into too much detail over one run. The Euro just brought back the storm after taking it away. 4 Link to comment Share on other sites More sharing options...

Not worried too much with ZR or precip types. still plenty of time for adjustments. I’m just glad Euro showed a storm. Will be interesting to see how many ensemble members are showing the different tracks. 2 Link to comment Share on other sites More sharing options...
chris624wx Posted January 14 Share Posted January 14 If it's going to be a ZR fest like the Euro wants to do, I'm fine with 33F and rain. I lived through a few bad ice storms in the early aughts in Georgia (thanks to the CAD....), and I've had my fill! Link to comment Share on other sites More sharing options...

There isn’t a true block in place. That could help or hurt us if the low trends more NW like the operational run. We need the low off coast of OBX. 3 Link to comment Share on other sites More sharing options...

That could help or hurt us if the low trends more NW like the operational run. We need the low off coast of OBX. Right, just like the 2/13/2014 storm, the NAO was positive, but we had a cold antecedent airmass ahead of a Miller A low, but nothing to keep the cold fully locked in despite a good track. So eastern areas mixed, and even turned over to rain for a few hours as far west as RIC before another 2-3" on the back side saved us. The 2013-14 was another winter largely diven by the -EPO. Here is the AKQ map from that event. RIC did slightly worse recording only 5.8". 2 Link to comment Share on other sites More sharing options...

It was the biggest snowstorm since 2/6/2010. Temps started in the mid-20s, and 3-6" fell initially, followed by warmer temps where RIC peaked at 37°F under +RA. Temps dropped and there was another 2-4" on the back side of the storm, but eastern areas did better on the back end. As you can see from below, the storm started in the south. Even Charlotte recorded 8.4" before eventually flipping. Link to comment Share on other sites More sharing options...
