What is an anomaly?

Every day, the Global Historical Climatology Network collects temperatures from 90,000 weather stations. Dating back as far as the late 1700's, the records provide an incredible source of insight into our changing climate.

Using this data, we can determine what the weather is normally like for most places on Earth. We can tell you that the average low temperature in New York City on January 11th is 29°F and that the average high temperature in Los Angeles on July 24th is 80°F.

Once we know what temperatures to expect on any given day with a certain degree of confidence, we can sift out the uneventful days, leaving only anomalous weather events.

3. Not looking too good for the midwest, if trends keep up.

Otherwise, the highs are higher and the lows are lower and I think we already caught on to that.
