wral icontrol shows -zr line from High Point to Hillsborough to Stern to Youngsville

It’s 33.4 here in northern Franklin County so I would say their icontrol is incorrect.

Hrrr coming in slightly colder Again

I had jumped up to ~35 earlier, but now have dropped to 33.6 degrees. For that to happen at mid day, colder air has to be filtering in now for us Triangle folks.

Yeah that's what happened here. Was up to 35 and got down to 34.7.

About how much ZR accrual do you have? 0.05”? 0.1”?

I would think around 005 maybe a little more Webb

 

[MichaelJ]

Currently here it is 31.6 with a DP of 31.2. Starting to get a little nervous about ice accrual, especially if it drops below 30 tonight

If it correct Raleigh northeastward and westward is in for significant ice (> .25").

And it would still be coming down (as freezing rain) for the areas described.

Is that QPF or FRAM? With temperatures so marginal, I would expect much of the raw QPF to not accrete, especially if it’s moderate/heavy rates.

I would guess it's only QPF. It's from the Pivotal site. Temps do get down to around 30 for my area over towards you. Dew points get down to ~28. With that, and this occurring overnight we may be able to pull something out of the hat.

Edit: it is QPF

Wow look at this unfold before our eyes .. now Raleigh looks to be really in the CAD wedge .. HRRR has hours upon hours of freezing rain and I’ve been checking the hourly HRRRs and something very dangerous I’m seeing is that dew points are getting lower for Saturday morning while precip is already moved in ... temps staying at 31 for a lot of it too here in Raleigh .. much colder than what it had even 6 hours ago

Here’s the FRAM

 

[Metwannabe]

Yeah that's what happened here. Was up to 35 and got down to 34.7.

Had recovered to a 34 here now back down to 32.5 so definitely colder air filtering in

 

[SD]

Well I'll join the cool kids club was up to 36 down to 35

 

[kstrickland0823]

HRRR is the only model that has my current temps correct. All others are showing 1-2* warmer than my actual temp. Will the HRRR win this one out again?

When I lived in Greensboro Clemmons was always a few below W-S/HP/GSO/Kernersville. Lewisville was always a tad cooler as well. Topography?
