But what is MM?

 

[ksu_aviator]

I tried numerous websites and couldn't find an MM abbreviation. Fltplan.com has the most complete list that I found.

Could be a typo.

It can't be a typo because it is an AUTO metar.

 

[J.Otto]

Never seen that one before.

MM = Miles/Mileage Missing??

Can't seem to locate the acronym either. Gave a quick call to FSS and they weren't familiar with it either.

It can't be a typo because it is an AUTO metar.

It could be if it is malfunctioning.

MM= Mega mama? One big ass TRW?

 

[mvedepo]

Thunderstorm with mammatus clouds.

Thunderstorm with mammatus clouds.

Sounds about right.. but if my memory serves me right the only thing I can think of that has "mammatus" clouds in it is cumulonimbus with mammatus clouds which is "CBMAM"...soo I'm not sure on this one.

Either way, it means stay the hell away...
