Sorry folks I stand corrected it seems you
can put SNOCLO on the METAR...never seen it myself and we apparently tried getting it on ours today but couldn't with the software we have. As Papa Oscar said though, I'd trust a SNOWTAM/NOTAM more than just the METAR alone
But hey, we're open and with 36m cleared width bring on the Heathrow diversions!!! lol
