Brushing up on things. Now it says whenever there is more than a trace of snow on the ground, and more than a trace of precipitation occurred within the past 6 hours. The remark is coded in the format4/sss. Still .5 inches or more right?

Report 4/sss when there is more than a trace on the ground at 0000, 0600, 1200, and 1800 UTC, regardless of snowfall.

Sorry, .5 inches rounds up to 1 whole inch for 4/sss, so report 4/sss if you have 1/2" or more on the ground.

7900 says more than a trace. Why? Mistake?

The error in the 7900 (needing more than a trace of precipitation to carry the 4/sss group) was noted last fall by the FAA. Contractors did issue a memo from the FAA concerning the error in the manual.
A fix was to come, however once the FAA began to concentrate in closing the program down, that fix was shelved.
The fix will come, at some point.
The 4/sss group is to be carried as was done last winter ... when 1 inch or more (reportable) is on ground @ 00z, 06z, 12z & 18z, regardless if you have more than a trace of precpitation ... ie ... 60001.

since snow depth is measured in whole inches, anything less than 1/2 inch would be considered a trace - "more than a trace" is anything that would round to a whole inch or more - 1/2 inch or greater, 1/2 inch rounding to a whole inch.

Does anyone know why some Ohio CWO's insist on continuing to enter the cloud code group in remarks? this has been going on for years

Since the new contract took effect, a FLSA likely has been put into effect which would clear the way for a site to carry above and beyond what currently is in FAAO 7900.5.
Prior to the new contract, likely lack of enforcement of the 7900.5 would be my guess.

We get a memo today now I'm really confused. It says
"We have found an issue with the instructions in the 79000.5C for snow depth reporting. The Depth of Snow on the ground group (4/sss) instructions should read the same throughout the document. That meant that what was in Appendix E.2 should read the same as what was on Table3-2 and paragraph 14.51.
It looks like instead of all reading the same, the changes were done backwards, now the section in Appendix E.2 is Correct, and what is in table 3-2 and paragraph 14.51 are incorrect.
In Table 3-2 and paragraph 14.51 it was added "...and more than a trace of precipitation occurred within the past 6 hours." This means no snow depth reporting at all (even if you have a couple of feet of snow on the ground) unless it snowed in the past 6 hours (see attached file).
You can even see the format in which these words were added to Table 3-2 and paragraph 14.51 are different. Both 3-2 and 14.51 should have this part taken out and the particular sentence end with "... observations whenever there is more than a trace of snow on the ground."
If you or any CWO have questions, contact me at number below.

Ok so what are they saying. They made that much more confusing then what it needs to be. Are they saying just report a 4 group whenever there is more than a trace of snow on the ground or as we all know .5. Or are they saying only report the 4 group if it has snowed in that 6 hours. Meaning 12-6 you have no snow so you have no 4 group at 6?.

That memo was sent out in October 2013. I wonder why it took so long to get to you...
The 4/sss group is reported whenever there is more than a trace of snow on the ground (so, 0.5 inch or more) regardless of whether any new snow or precipitation occurred in the past 6 hours.

Good Question Prplra? Maybe our contractor is slow at getting stuff out? I have no clue. However why can't they just come out and say The 4/sss group is reported whenever there is more than a trace of snow on the ground (so, 0.5 inch or more) regardless of whether any new snow or precipitation occurred in the past 6 hours.

Why can't they just make it a very simple statement that says "whenever there is 0.5 inches or more of snow on the ground".?? That's pretty straight and to the point and one which everyone should interpret in the same manner. "More than a trace" could be open to interpretation to an inexperienced observer or lead to questions that would not otherwise have needed to be asked.....

Coco, that's because that's what happens when you have non-weather people running the show. The FAA really doesn't get it. I think they think that weather is like magic or something and that it cannot be observed, let alone predicted. Sorry, I'm going off on a tangent.....the bottom line is that it would be too easy to have writing that is straight-forward in the 7900. It needs to sound more like lawyer talk to make them think they're getting their moneys-worth.
