I also had contacted the WxChallenge manager, and he got back to me. Apparently, he contacted the Reno NWS and they do not want to change their 25kt value. So we are stuck with the 25kts unless the NWS changes their mind.

Wow it shouldn't even be whatever they choose the computer itself should have recorded those values and changed accordingly unless there was not a true representative 2 minute period of higher winds which I find hard to believe. 

That's almost like saying today will go down at 20 knots instead of the clear time where it went to almost 25+ knots today. They can change it but they have a limited time before it locks in as climo.

Yeah, that's what confuses me. It seems like the automated system would have captured the correct value, which means that the current incorrect value would have to have been entered by hand. It's also strange that it shows it as a southeasterly wind, when almost all the strongest winds were SSE or S. And the five-minute observations show 2-minute wind speeds, so by definition the highest wind should be at least as high as the highest 5-minute observation.

I think we are going to need an explanation from the KRNO office on why they don't want to change their 25kt value, especially when there were 12 separate 5 min instances where the winds were higher than 25kt. 

It doesn't affect me too much for my WxChallenge forecast for yesterday, but it does affect the scientific integrity of their ASOS station climatology (especially if these discrepancies occur regularly). A potential discrepancy of 5kt is rather significant.

Agreed on all counts. The winds yesterday were consistent with what was expected, and the observations were not flagged. The observations looked perfectly reasonable and reliable throughout the day, and it's very strange to me that they would choose to ignore those observations in the daily climate report.

I still have not received an email response from the Reno office.

I agree as well.  Interestingly, today's afternoon climate report shows a maximum wind of 30mph/26 knots, so it was done correctly today.  Yesterday's needs to be corrected.

47/23/11/0.00 for tomorrow.

I just got an email back from the Reno NWS, and they found that the estimated 25kts was due to a minor error (possibly a power blip) which caused the script to grab the highest hourly wind speed instead of the highest wind speed. They have since fixed the wind speed to 35mph in an updated climo, and sent a message to the WxChallenge Twitter. Sounds like it's going to be fixed!

I feel at this point it really shouldn't do much but change a few scores and just add to error points but at least they are catching it. Soon we will be having to forecast snow to liquid that's always fun.

Yep, I noticed it's been corrected on the WxChallenge results as well.

Excellent, I'm glad they fixed the issue!

Where were you guys, the ones at 20+knots, looking at? I can see how they may get to like 18 maybe 19 if they manage to bring down that stronger wind.

Good luck all

NAM BUFKIT showed 23 kts at 450 ft AGL in the early afternoon. GFS even higher though it tends to overdo it I think.
