Interesting to note Gainesville, GA airport is now at 32 according to NWS Obs. Showing unknown precip.

Hickory reporting .4" of ice accrual. Forsyth County has over 30,000 without power. Over 10,000 in Guilford so far. Here in NW Randolph, I see minor glazing, but no issues. Looks like the NWS forecast is verifying well.

Note that both Hickory and Winston-Salem (in Forsyth County for those who don’t know) had all hourly readings of 31-32 during all of the ZR. The point is that it doesn’t normally take upper 20s to get a major accrural just above the ground though it sometimes takes that for the streets to get really bad. A good number of the worst ATL icestorms had 30-31 and even up to as high as 32 in a few cases. Some of this knowledge is from personal experience.

Correct. The roads are fine, but the ice on the trees and power lines have caused downed trees and the power outages.
 
roads seem fine here...but 40,000 without power in Forsyth currently and that number is rising fast. Though the rain has ended, the weight remains on the tress/power lines. So expect more outages around here. IMG_1147 (1).jpg

I'm no expert on freezing rain...but I'm guessing the icicle formations probably don't count on the official accrual count, but it seems to me they add quite a bit of weight

I don’t think they count explicitly as the accrural would be much higher. My understanding is that typical accrurals are often in the 0.4 to 0.5 ratio to ZR that falls in rain gauges as much of the rest drips to the ground immediately, especially if heavy. Anyone know how much ZR has actually fallen at Winston-Salem and the accrurals there so we could see the ratio? Also, I saw per Packfan that Hickory got a whopping 0.40” accrural. Anyone know how much ZR fell in the gauge there?

There is a 3 day history link on the point and click forecast pages from NWS.

We (Roanoke) busted low overnight fortunately! .28 instead of at least .75 that every model I looked at said we would get. as late as even the 00 hi res stuff.

Thanks for that link. So, HKY got 0.40” ice accrural from only 0.52” of rainfall? Wow as that is an unusually high ratio of accrural to rainfall and it only got down to 31! Just goes to show every situation is different and accrural rates of ZR are highly variable
Meanwhile, I just found this:

I remember on ZR event we had a few years after the Jan 1973 Ice Storm.. I lived in Hapeville (near KATL) at the time.. official low was 33 and since this was before I had any instruments at all, from the accumulation I saw, it looked like 2M temp stayed just above freezing, ( no ice on shrubs, cars, or Mom's clothesline/.. but was ice on trees, powerlines and even the service line to the house.. only time I ever remember that occurring...

Yeah I see, dont think they make here however and not sure upper levels support snow yet either. Coastal low developing nicely though winds gusting in the 20's now..... brrr
