Ryan has been posting on Twitter continual updates of ZR accumulation at KHVN. Does anyone know how to get updated ice accretion at the airport ASOS stations? The PNS statements are old, from 9:29AM

You can add up the “I” column in the metar. But I think oceanst said be careful because it measures on flat surface and real accretion on surfaces like wires and trees does not work like that.

Raw METARs.

Pretty sure it’s just an algorithm off of the ZR sensor.

I'm ignorant here..help me out... I thought that was just total liquid that has fallen in the last hour/3hours/6hours whatever and not nessisarily ice acrettion due to factors like run off, temperature, expansion of water, etc etc....

HVN, for example is also reporting a mixture of UP and ZR, so there could be times of sleet mixing in as well. Not sure about HVN but here there was ZR then IP then back to ZR 

Just trying to figure out a valid method of reporting ice totals

The I groups are 1,3,6 hr accretion. The regular P and 6 groups are 1,3,6 hour pcpn.

Schizophrenia storm.  Rates change every 10 minutes.

Tiny ice pellets now, that will not be great on the roads.  27F

I've been keeping an eye over the ALB area on radar as that's the stuff that will get here and that seems to have filled in and looks to be blossoming some too.
