There is a new site section available at NOAA which shows weather extremes for all states. A U.S. map with links to each state provides a summary of the extremes. These are statewide annual extremes. So you have one maximum and one minimum temperature record for each state. There are also three precipitation records for each state. Basically, this is a 250-entry dataset. Pretty bare bones.

I had been hoping that the additional data used to create these data summaries would be incorporated in this part of the NOAA website, but so far they have not appeared.
As a result, the archived records may not reflect all of the recognized records depending on whether or not they were recorded at a NOAA affiliated weather station.Hopefully, that will be the next stage of creating a comprehensive statistical database of state weather records at NOAA. I've posed that question. My contact at NOAA has been very helpful in keeping me updated on the development of the new webpage [top], so I hope to hear from him concerning the possibility of having the data pushed through to at least the monthly level. Part of the problem may be aligning non-NOAA data with NOAA's archived data.
But for now, if you knew about January 2009 all-time minimum low temperature for Maine [minus 50°F], you would find it through the top page, but not the bottom...
