Yahoo weather temperature forecasts for next week in Washington DC have been incredibly wrong when I used the weather app or checked the Yahoo website for the past week. Even now, on 1/24 at 7:30 pm EST, it's saying the low on Monday 1/26 will be -2 degrees F, when no one else is predicting below 8 degrees for Monday or Tuesday (except Accuweather, which I don't trust either). Earlier this week the Yahoo forecast for next week in DC (or Potomac MD just outside DC) said the temp would drop to a ridiculous -7 degrees, a temp not seen since 1934. I tried to send this as feedback to the app but that failed no matter what I tried.
