Notes:

• I'm experimenting with displaying 48 hours of past data. This lets us compare today with yesterday.

• During subfreezing conditions, the rain information is bogus because I don't have a heated tipping bucket.

Other presentations:

• Historical data and other whatnot,
  currently just plots of High/Low temperatures during recent months.

• Historical data from an interactive form.
  My weather data lives in a database. This tool let's you say what you want to look at and then gives it to you graphically.

Originally I had to run Davis's WeatherLink while I was working on a Linux interface and working on getting away from Windows altogether. The graphs in the Linux presentation are now in pretty good shape I think are better than what I can play with from WeatherLink. In particular, I can put multiple variables on a single graph, very useful for things like air temperature and dew point. I've also forced some vertical scales to meet minimums, so you can glance at the barometer graph and tell if the barometer is low or high. The vertical scale runs from 29.40" to 30.60" instead of WeatherLink's stretch to fit graph.

Non-weather local links: Yes, Penacook has a home page. Penacook is a village that straddles the Concord and Boscawen town line. It also straddles the Contoocook River near where it joins the Merrimack. Hannah Dustin was an early visitor here. Unfortunately, she had been kidnapped by indians several days earlier. They killed her infant child to help speed their flight from Haverhill, Massachusetts. The statue to the right commemorates how she escaped by killing and scalping ten of her captors on an island at the confluence. My home page. Paula Werme's DCYF Web site. Nearby Geocaches.
