      This has been my experience when looking at the hourly temperature predictions. The “day” starts at a normal wakeup time

    It’s right in your title:

    predicted low

    Predictions are not guaranteed to occur, thats why they call it a prediction and not a prophecy.

        Not when it’s early morning. The temperature is on the rise from the previous night. The prediction you’re seeing is for the coming night.

    1. Weather predictions are not 100% accurate.
    2. The place making the predictions may be using different instrumentation or be in a different location than the instrumentation used to give you real time info. This is also why what the app says it is and what a thermometer right in front of you says can also be different.

    This depends on the implementation of whatever you are looking at. The weather app I use does integrate actual measurements in the forecast for today.

    Aren’t the highs / lows what were forecast and the current temperature based on actual measurements from weather stations?

    I guess they don’t update the high/low to match observed readings.

    The announced numbers are based on the station that records the data which likely has a different microclimate.

    An example, the weather station I use is recorded at an international airport so the heat of the sun reflecting off the concrete causes the low to be higher than my place on the other side of a hill which gets the sun later in the day.

    Forecasts are generalisation of weather as predicting the future is not possible.

    Thermometer reading vs perceived temperature? Factoring in wind-chill, humidity, etc with “Realfeel” or some other estimate.

    I know it doesn’t really answer your question, but that UI is so confusing. What does “13°F Today 29°F/16°F” mean? We can assume that it means it’s 13°F right now, and today was predicted to be a high of 29° and a low of 16°, but there isn’t really enough information to know for sure without additional context. The 29°F/16°F could be the predicted highs for the morning/evening instead. 13°F could also be the predicted temperature for today and 29°F/16°F could be tomorrow’s predicted temperature. There’s just not enough info to know what the numbers are saying.

      Out of context you’re right, but most of the time when you open a weather app you’ll get a more detailed view where you can see, in this example, that 29 is the high and 16 is the low for the day with 13 being the current temperature. Once you look at that one time you would know what these numbers are in this shortened view.

    What’s that “F” behind the number? Does it stand for "F"uckinghelliamlivinginacountrywithouthealthcare?
