80 degrees and snowing??

[John Vandehei]

I was just looking at the lasted SFC map on the COD weather page and noted the moderate snow symbol next to Terra Haute, which was reporting 80 degrees. Thinking it was likely a computer problem on their (COD's) end, I check the surface map from UW Madison. Same moderate snow symbol. Obviously, it's not snowing there. I don't know where to access past METAR reports. Just wondering if the ASOS kicked out an erroneous report, or if it was a glitch somewhere else.

This must be some error with the station itself. Danville has also been reporting light snow all day despite 10 mi visibility and clear skies:

Oops, Danville, not Terra Haute. My mistake. Where do you get previous METARS from?

 

[Jeff Duda]

You can get them from the box on the right side of the surface page of the RAP site (where it says "text observations"):

Obviously it is instrument error. I would assume it is with the ASOS itself and something in its "precip. detector" being bad. I saw that a few weeks ago at Danville so it must be an ongoing problem.

The Danville sensor has been on the fritz for a while, I captured this on May 2nd...
