If we want to judge conditions for the way they affect us, you judge the conditions with how we live in them. Of course it is easiest to eliminate external variables affecting the weather readings at an airport, but since buildings, pavement, etc in cities have a significant affect on weather conditions, this should be taken into account. The whole point of a heat index is to tell us what it FEELS like outside. Again, difficult to do in practice, but how heat is actually affecting us it isn't just academic.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3483614767822693875.post-61181862976405607622011-07-19T23:27:37.665-05:002011-07-19T23:27:37.665-05:00Thanks for the great input, Nick.

As it turns out, airports almost always meet all of these criteria, and most of the surface weather observations we rely on in this state come from airports.<br /><br />I'm not sure how much of a role, if any, the NWS plays in the siting or maintenance of the weather observation network in this state; in Oklahoma, where I went to college, there was a state agency that managed all of that; I suspect it's mostly a mix of the FAA/NWS up here.Nick Bensonhttps://www.blogger.com/profile/05992303938849328959noreply@blogger.comtag:blogger.com,1999:blog-3483614767822693875.post-86146604484148784252011-07-19T22:07:29.963-05:002011-07-19T22:07:29.963-05:00http://www.crh.noaa.gov/news/display_cmsstory.php?...http://www.crh.noaa.gov/news/display_cmsstory.php?wfo=arx&storyid=70928&source=0<br /><br />Some of the heat indices reported from around the area...Dennisnoreply@blogger.comtag:blogger.com,1999:blog-3483614767822693875.post-17314266244406534872011-07-19T19:49:32.171-05:002011-07-19T19:49:32.171-05:00There also seems to be some question as to whether...There also seems to be some question as to whether the 119 heat index was tied. Several forecasters tweeted the 119 but Paul Douglas's blog says only 118 was confirmed.
