That snow was formed below the melting layer (~8,000ft-ish). So sleet that you see formed above that, and flakes formed below. For you VA folks, if you stop seeing the tiny flakes, good chance you're gonna go to FZRA within a few hours. Great explanation and a pretty rare set up! 1 Link to comment Share on other sites More sharing options...
TSSN+ Posted January 25 Share Posted January 25 I just cleared 1/2” sleet in the last hour. Very well might end with 3-4” of sleet here. Woof. Link to comment Share on other sites More sharing options...
Bob Chill Posted January 25 Share Posted January 25 Still 100% sleet down here. Comes in waves. Lulls have tiny sleet that are more like snow than sleet pellets. Holding at 18 degrees. Prob in the 3.5" range of total snow and sleet. Grass is covered so I'll pretend it's a foot deep. One thing for sure, all of us are going to have snow-covered ground for a long time.

katabatic Posted January 25 Share Posted January 25 What a strange storm. Still only 6 degrees with heavy sleet. I shoveled a bit and except for a tiny bit of snow underneath the sleet, it's been all ice here. I'm estimating 4" otg and the plows are keeping everything clear - even went to the gym and there were plenty of folks there, too. Hopefully we will flip back to snow as the system moves north. Regardless, this stuff will be around until April. 1 Link to comment Share on other sites More sharing options...
high risk Posted January 25 Share Posted January 25 1 hour ago, WxUSAF said: @high risk your 13-14z call for the mix time was spot on. Was about 1330z for MBY. But this mix of sleet and needles is interesting. Visibility is way lower than normal for a predominant sleet precipitation event. I'm curious how this will accumulate. I think @csnavywx and @Terpeastwere suggesting we're getting snow to crystallize below the inversion to mix with the sleet that's coming from higher up? I'd like to take credit for a call, but I rode the NAM Nest. If I had a dollar for every "LOL NAM" and "the NAM sux" posts in the past 3 days, I could have retired early. I completely understand the skepticism back on Thursday and Friday, but once we got inside of 36 hours and it didn't budge, I thought it had a high likelihood of verifying with p-type, even if it did a poor job with QPF prior to the flip. 6 1 Link to comment Share on other sites More sharing options...

Lot of drifting so my usual measurement spot isn’t accurate. I had 6” on my driveway 2 Link to comment Share on other sites More sharing options...

Sleet "dust" has blown through our screened porch and it looks like somebody dumped a bag of flour on the floor. Not sure how the big slug of precip is going to break in a few hours. Hoping it's a sandstorm and not zr. So far there are no icicles on anything (which is a big relief) 2 1 Link to comment Share on other sites More sharing options...

We had some events like this back in 1994 w sleet/freezing rain w temps in the teens in the DMV and heavy snow north of the M/D (I was only 9 at the time so I don’t have a great synoptic memory of it) Link to comment Share on other sites More sharing options...

There were some decent snow events in the analog mix too so a simple analog blend nailed the outcome pretty good. Link to comment Share on other sites More sharing options...

I walked outside like 10 minutes ago and there f’ing CHUNKS of sleet coming with diminished visibility. I’m guessing that there are small flakes/needles in there, which is bringing the viz down and helping with accumulation just a bit. Link to comment Share on other sites More sharing options...

I was concerned but hard to take it seriously when everything else was colder including the Euro.

You'd have to find some really old timers to remember when something like this occurred. Can't forget 2/07. Not because of the storm, but because the guys that replaced my water lines the summer of 2006 hit the one side of the power line to our house, so we lost 1 leg of the 240 power to the house of all days but the day of the storm. Which meant no heat pump without 240 volts. Froze for 2 days before it was fixed due to many BGE crews having been sent to other parts of the country from storm the week earlier. 1 Link to comment Share on other sites More sharing options...
