i found this in a prelim report where an SR20 crashed into trees on approach and killed 3 people. Ive never seen something like this on a METAR, what does it mean?

WEATHER: SPECI KSWF 210700Z 00000KT 1/4SM R09.2200FT FG 04/04 A3008

Runway visual range on 09 of 2200 feet?
 
ah yea that makes sense. that period in there was confusing me.

It's the New York way of saying RVR, they always make you think up here.
 
Jason,

is it supposed to say RVR092200 ?

obviously i never fly out of or into places with RVR...

It's supposed to say R09/2200FT between the visibility and any precipitation. We have an RVR for runway 16 at HPN, so we see it when the weather is down to mins.
 
ok thanks work Mr. I Just Passed my Private Pilot Oral :D

Speaking of METARS, probably not the best day to do a checkride:
KHPN 211756Z VRB03KT 1 1/4SM BR VV002 08/07 A3000
 
haha kent, ive been learning lots from Jason for a long time. He's one of these whiz kids, like i used to be before i forgot everything

haha, yea right. You have just about every instructor certificate out there...I certainly don't. I think the extra expense to fly out of HPN is certainly worth it. Things like RVR in the METAR and wake turbulence procedures are normal occurrences.

...and yes, today was not a good day to fly -- rescheduled for early Sunday morning before the rush starts.
 
Ya, I think the AWOS gnome just hit the wrong key when it was typing out the METAR. Kind of like how we were warned of "Light Freezing Snow" today. That's either redundant or simply flying in the face of the rules of physics and meteorology.

When it gets to 100 feet (or 50+ if you're rounding I guess)...

Ever seen OVC000? That's 'cuz OVC000=FG.

Not exactly the same as you posted, but I saw this Wednesday into Thursday quite frequently:

[FONT=Monospace,Courier]KHPN 220456Z 00000KT 0SM FG VV000 11/10 A2986 RMK AO2 SLP114 T01060100 401060028[/FONT]

There could be kinda a possibility of a definite maybe the items in red might be a correlation? Maybe even some influence by the numbers in blue?

I'm no meteorology expert so it's just a way far out there guess. Once I read the Lester book, maybe I could address it with a bit more confidence.
 
Vertical Visibility is different than a ceiling report, specifically, VV is used when there's no discernible ceiling (because of fg, br, or other obscuration). It's not too often you see 0SM, especially at an airport that is RVR equipped, but the temp/dew point spread (or lack there-of) just means it's going to be bad ceilings/vis due to hight moisture levels.

That's what gets me. FG, by definition, is not a ceiling. Above 35 agl, it becomes a cloud. (I think it's 35.)

OOO OVC is indefinite ceiling. I have observed this and it's impossible to say the elev of the actual ceiling because of the fine graduation of visible moistre beginning from the surface to the actual ceiling.
