I Heart Weather Data

Anytime we have interesting weather I love to pore over the data my weather station is collecting. The past two days have given me lots of chances to do just that.

On Friday we recorded our first 80 degree high of the year (84.4, to be exact):

The WGN Weather Blog reported it had been over six months since we last saw temperatures that high. Now that I've recorded about 10 months of weather data via WeatherUnderground, I pulled up a chart of temps for the last 6 months:

A quick scan verified that stat. Early October (the 12th, the be exact) was the last time temps were as high they were on Friday. The chart also reminded me just how cold it got in mid-January!

And then Saturday's weather was even more interesting. Here's a chart of temps:

We had two big temperature drops during the day: a 15-degree drop from 12:30 to 1:30, and a 10 degree drop between 4 and 5. These drops coincided, as you might imagine, with a change in wind. The first temperature drop happened right as the wind shifted suddenly from the SW to the NE:

While the second drop occurred right when the wind picked up again, after having died down for a couple of hours:

And, finally, we got about half an inch of rain over the afternoon and evening:


Wendy and I spent the first half of Saturday working in the yard, removing dead bushes, transplanting hostas, and pulling up weeds, so we got to experience the 15 degree temperature drop firsthand. Eventually the rain, and our stomachs crying out for lunch, forced us indoors.

After the 10 degree temperature drop in late afternoon we were forced to close all the doors and windows, because it was just cold with the wind blowing through our house.
