Maybe to protect against hot jet blasts souring the reports Have to wonder how different the records would be if that rule did not exist. Plus...in a time before automated stations did somebody really stand outside for minutes to make sure the analog thermometer stayed there before declaring the high?!

The term weenie now applies to heatwaves. lol I like seeing such enthusiasm for weather. I've been into it for as long as I can remember and this board is one heck of a gathering place for like minded people. I never paid attention to heat much in the past. I blame amwx for furthering my affliction for wx. Link to comment Share on other sites More sharing options...

Ian Posted July 7, 2012 Share Posted July 7, 2012 Regarding the 100s at IAD it is an interesting stat. While BWI and DCA obviously observe more overall, the same can generally be seen at those locations the last three years. They both avg about 1 per year through the record--or did before 2010. DCA has now done 4, 5, 4 the last three years and BWI has done 7, 5, 2. I guess we hope it's just a bump in the long term road. Link to comment Share on other sites More sharing options...

mattmfm Posted July 7, 2012 Share Posted July 7, 2012 Dr. Forbes, speaking about the Philadelphia area: "You need to move indoors right now." #severe That line doesn't even look severe at this point.

CapitalClimate Posted July 7, 2012 Share Posted July 7, 2012 And speaking of bad data, why does the 6:28 LWX AFD show this for the climo section?

Looks like TWC has joined the post-derecho pandaemonium, after calling it a derecho earlier. Well it's had a history of producing some pretty wicked wind gusts...a spotter in Lehigh County measured a wind gust to 68mph. Not saying the damage would be widespread, but if you get hit, you'll get it good. Link to comment Share on other sites More sharing options...

That part probably was not updated - it was probably an update for the STW. If you wanted climate info/record info you need to read the climate report not the AFD.

They probably have the same rounding error that wunderground does. They use the already rounded celsius temperature to convert to Fahrenheit. That introduces problems at certain temps.
