Comparing 4 Different Weather Forecasts

I jotted down weather forecasts for Lafayette from 4 different sources: WLFI, the National Weather Service in Indianapolis, the Weather Channel, and AccuWeather on the evening of June 17th to see they would do with a 7 day forecast. I'm just using temperatures for this "contest". Here are the forecasts for yesterday and the actual numbers, plus the margin of error for each in ( ).

June 18
WLFI: 92º/75º (+10º/+7º)
NWS IND: 84º/71º (+2º/+3º)
TWC: 87º/69º (+5º/+1º)
AccuWx: 85º/69º (+3º/+1º)
Actual: 82º/68º


Forecasts for today (again from 6/17):
WLFI: 93º/73º
NWS IND: 83º/67º
TWC: 83º/67º
AccuWx: 88º/72º

  2. Accuweather beat the NWS in the overall. Never would have guessed that.
