First off-- I'am not present and not the WX OBS at KBOS. SO I don't know for sure. But things would sure seem that a SNINCR remark should be added for KBOS-- NO??
KBOS 270654Z 36020G28KT 1/4SM R04R/2600V5000FT +SN BLSN FZFG VV005 M09/M11 A2972 RMK AO2 PK WND 36031/0613 SLP063 P0009 T10891106
KBOS 270554Z 36022G33KT 1/4SM R04R/3000V3500FT +SN BLSN FZFG VV005 M08/M10 A2976 RMK AO2 PK WND 01033/0545 SLP077 P0000 60010 T10831100 11017 21083 58050
all the other major airports in the area have added "SNINCR"--- KJFK/KLGA and the heaviest snows seem to be based on radar returns in SE New England.
Maybe the BLSN has added a difficulty?? But P0009 seems a "little fishy" The ATC I work with at has noted that SNINCR 1/4 "etc" is huge for their operations. Just saying..... .09" of a "P" group should easily reach 1" of SNINCR. if not 2" at those surface temps.

I might add--- a 1/4SM surface VIS at night in an Urban setting-- with +SN as the primary-- is the real deal.

looks like BOS is exempt from snow measurement according to 7900 appendix G.4

looks like BOS is exempt from snow measurement according to 7900 appendix G.4 Would be nice to see a list of what stations are "exempt" and why. You would think an updated version of the 7900.C would list what stations are exempt. KPHL may be another. For as many "errors" we find in ATC obs-- and they are numerous-- I would hope we have a list of major airports that don't have to report "4" group and "SNINCR".,, since the 7900.C clearly states that a "SNINCR" and "4" group MUST be reported. --- location may be the issue... Just sayin.... I personally know of NO other Major snow sites (A's-- Core 35) that do not report a "4" group and "SNINCR"--- (KPHL may be another) . I personally know the FAA watches are Ob's like we watch them... |

if it is too far to a decent snow measuring are...a station is exempt...I think Denver is exempt. We are the only CWO in the metroplex that is required to report snowfall. and we have to walk about 100 yards to do it. one airport started using a civilian on the ground...and record snowfalls were being reported. proly measuring the drifts...

From pages 168-170 of the 7900:

I don't like it. Snow on the ground, then report it. 4-group, 933-group, and SNINCR. All of those groups are very important to aviation. However, I do know a site where it's impossible to do snow measurements because they're right on the tarmac with no grass or any other good place to measure in site. Even they get measurements from the local NWS office though.

You also have to take into account the if they have a suitable area to actually measure snow at as well. Larger airports might not have access to a suitable area to measure snow, or it they might have an area suitable but it is to far away to do measurements in a timely fashion.

The snow list doesnt mean squat to the FAA... There are stations on the snow list that have closed down and cease to exist...so being on the list is no guarantee that you are doing snow measurements...and you know very good and well ATC isnt doing it...oh, i forgot ...the baggage handlers, ramp jockeys and fuel truck drivers are doing it... Total BS

KBOS hasn't done snow measurements since their office was relocated 8-9 years ago. |

My point is that the National Weather Service/FAA need to get their respective heads together and figure this stuff out if it's important (and it is in this case) by putting observers in places where they can disseminate appropriate observations themselves or have the ability of others to get them the information they need for the observations. Just my 2 cents.....

If that was your point why didn't you say that instead of calling out the site for not reporting something that is not there responsibility and hasn't been for years. Maybe you should get yours facts straight first,
Just my 2 cents.....

Uh, I didn't call anybody out wxornot. Maybe you should read the message and who anon is referencing first instead of being a smart ass.
