### Instantiate a `high_temp` and `low_temp` variable
We're assigning the temperature from the 0th record in the array to get started.
```jinja
{% set high_temp = weather[0].temperature %}
{% set low_temp = weather[0].templow %}
The weather entity stores forecast data in the forecast attribute as an array of forecasts.
The forecast array looks a little like this.
Now it's only in this writeup that I've made the realisation that I got some fundamental concepts in my video wrong.
Each item in the "forecast" array is actually for a "Day" not an hour..... OOPS!.
```yaml
forecast:
- condition: partlycloudy
datetime: '2023-06-05T02:00:00+00:00'
wind_bearing: 118.2
temperature: 17.7
templow: 8.5
wind_speed: 18.4
precipitation: 2.7
- condition: partlycloudy
datetime: '2023-06-06T02:00:00+00:00'
wind_bearing: 14.2
temperature: 17.8
templow: 11.8
wind_speed: 21.2
precipitation: 0.1
- condition: rainy
datetime: '2023-06-07T02:00:00+00:00'
wind_bearing: 20.6
temperature: 17.3
templow: 12.7
wind_speed: 18.7
precipitation: 23.9
- condition: partlycloudy
datetime: '2023-06-08T02:00:00+00:00'
wind_bearing: 277.1
temperature: 14.6
templow: 10.3
wind_speed: 15.8
precipitation: 0.6
- condition: partlycloudy
datetime: '2023-06-09T02:00:00+00:00'
wind_bearing: 281.9
temperature: 13.8
templow: 10.4
wind_speed: 20.2
precipitation: 0.4
```
### Iterate through the array and set the `high_temp` or `low_temp` variables accordingly.
I've also added an `if` statement in here to announce if any of the forecast conditions are `rainy` and the `hour` that the rain is forecast for and to tell us to take an umbrella.
I've surrounded that code block with `###########` for clarity
```jinja
{% for entry in weather %}
{% if entry.temperature > high_temp %}
{% set high_temp = entry.temperature %}
{% endif %}
{% if entry.templow <low_temp%}
{% set low_temp = entry.templow %}
{% endif %}
###########
# While we're here, if the condition for this hour is `rainy` let's announce that
{% if entry.condition == 'rainy'%}
It looks like there's rain expected at around {{ entry.datetime.split('T')[1][:2] }} o'clock.
You might want to take an umbrella if you're leaving the house.
{% endif %}
###########
{% endfor %}
{% set high_temp = weather[0].temperature %}
{% set low_temp = weather[0].templow %}
```
