“Use my location” asks your browser for your coordinates so we can load your local forecast and any official warnings for your area. Your coordinates are used for that request only: they are not stored on our servers, sold, or used to build a profile. If your browser blocks location, we fall back to an approximate city-level lookup from your IP address.
How accurate is the Grand Prairie, Texas forecast?
Every night WeatherSignal writes down what it is predicting for Grand Prairie, Texas for the next five days. Once a day is over, the same coordinates are checked against the measured record and the difference is published here — including the times we got it wrong. Nothing is back-filled, because a forecast written after the fact is not a forecast.

What changed since yesterday
Nothing moved enough to mention. When a day’s high shifts by 4°F or more, or the rain chance swings by 20 points, it is listed here instead of being quietly rewritten.
These scores cover WeatherSignal’s own published forecast for this exact location. Measured values come from the same public analysis archive used for historical weather, and can be revised upstream. A day only appears once it has been both recorded in advance and scored afterwards.
