Erroneous Freezing Rain Reports Picked Up From METARs

Youngling Posts: 2 Join Date: 2/3/17 Recent Posts

Good morning,

IRIS added some trace FZRA reports from METARS into the All Weather Reports table (see attached) from KEKN and KCRW this morning 0951/1051Z (0451/0551L) & 0954/1054Z (0454/0554L) respectively. There were no I groups in the reports, temperatures were above freezing the entire time; at EKN - no precipitation was reported during this period at all. Any idea where these trace freezing rain reports are coming from?

That's a 24 hour value in IRIS and both stations reported an I group earlier in the day in the METARS.
