I would like to post a link to a NWS weather document making some observations concerning the weather on and about the 26th. that are contrary to my previous understanding. The NOAA daily summary for Boulder reports that a trace of snow fell on the 26th. (according to the government this amounts to less than 0.01” or one hundredth of an inch, http://www.srh.noaa.gov/jetstream/append/glossary_t.htm ). I have spent considerable time trying to determine what time this occurred believing that it would have been between midnight and 2:00 AM. Some months ago, I found the original daily report filed with the Denver NWS station by what the NWS calls a "Coop" or "weather enthusiast" station located in the Ramsey's Boulder neighborhood (actually within two blocks of their house). These stations are operated with official NWS equipment by volunteers trained by NWS
(http://www.nws.noaa.gov/om/coop/what-is-coop.html). This particular station was apparently managed by a graduate meterologist student at C.U. who lived in the neighborhood. The significance of the report is this: The trace of snow actually fell from 5:00 PM to 8:00 PM on the 25th. as a front came through the area, not on the 26th. as was commonly reported, and the reason for this is due to the time of observation for the station. Once a day, at 5:00 PM, the station "enthusiast" (who in other reports for this station gave his name as John Brown) was required by NWS protocol to personally observe the weather at his station. This personal observation officially ended the recording for that particular day. You will notice that there is a bar drawn from 5:00 PM to 8:00 PM for the 25th. as that indicates the trace of snow AND, as it occurred AFTER the official time of observation, it was entered on the 26th. as "T" for trace amount. This was an aberration for that particular station as many, or most, make their observation close to the actual end of day, or midnight. Perhaps this fellow came home long enough to eat supper and then headed back to the campus or the National Weather Station a few miles away to work and could not be there later in the evening to personally observe anything. The rest of the measurements are taken from equipment recordings. Notice that the temperature dropped 42 degrees at 5:00 PM to 10 degrees by midnight as reported in the station manager's remarks to the right. The low of 6 degrees would have been reached early on the 26th. prior to the sunrise. So, what does this mean to the case? Probably not much of anything because snow never fell on the west or the north sides of the house that evening - the crime scene photos and individual witnesses prove that - regardless of when it fell. And, one hundredth of an inch or less of snow over 3 hours is not much, maybe one flake per square inch. The snow that was there on the Ramsey lawn was left over from several days prior and much of that had been melted in the interim by the sun until what was there was in random patches - certainly not covering the entire yard.
