Is that from a lack of QPF? Gotta be colder in EC than here. 

No idea. I'm sure DC had more precip than us today, but there was precip here. It just seemed like it melted in the middle of the day. Maybe the cloud deck wasn't as thick here because the precip wasn't as heavy and that allowed the mid February sun to do some work?

This might be the worst case scenario ...light precip, well below freezing and continuing after sunset.  

I'm not sure. Beginning to wind down right as the sun goes down. Without further accretion there's not enough standing water to create problems on the roads. I'd think this has to hang on till 7-8 to cause real problems, and radar doesn't show that to be happening. Worst case scenario would've been if this all started just a couple hours ago.

Starting to get impressive out there. Icicles have connected with the ground under my wifes car. My truck sits much higher but even those icicles are trying to connect. Street is crust covered. Not bad for daytime zr/sleet in mid Feb

That's why im sad about the disaster on Tuesday. How did we lose our 13 degree cushion

Digital cushions are weak AF. One accidental ctrl+alt+delete and it's over

It’s hard to believe that we even suck at freezing rain ice accumulation. I’m ready for spring

Same here. It's not like it's 31 and raining hard. It's been 27-29 and lightly raining/mixing all day and the tree branches here aren't sagging, nor is the untreated sidewalk anything but wet. Seems impossible.

Just took a walk with the dog.  Sidewalks greasy but not slippery, if that distinction makes sense.  There is a glaze on all elevated surfaces, but nothing significant.  Maybe 1/8”.  This would have been a big deal if it happened overnight.

29.2

This 100%. Snowcover helped, but transpose this forward 6-9 hours and throw in some slightly lower ground temps and it would be way worse. It's very close as it is, but accretion efficiency wasn't quite there for a big dog ice storm.

I guess what do the next 12 hours look like? Light drizzle and more precipitation to the south should add more accretion, right?  
 

I’m worried we’re calling it over before it’s over.
