recursive CTE from Ordinary CTE - sqlite

Question

I have a with clause that groups some weather data by time intervals and weather descriptions:
With
temp_table (counter, hour, current_Weather_description) as
(
SELECT count(*) as counter,
CASE WHEN strftime('%M', time_stamp) < '30'
THEN cast(strftime('%H', time_stamp) as int)
ELSE cast(strftime('%H', time_stamp, '+1 hours') as int)
END as hour,
current_weather_description
FROM weather_events
GROUP BY strftime('%H', time_stamp, '+30 minutes'),
current_Weather_Description
order by hour desc
)
select *
from temp_table
Result {counter, hour, current_weather_description}:
"1" "10" "Cloudy"
"2" "9" "Clear"
"1" "9" "Meatballs"
"2" "8" "Rain"
"2" "7" "Clear"
"2" "6" "Clear"
"1" "5" "Clear"
"1" "5" "Cloudy"
"1" "4" "Clear"
"1" "4" "Rain"
"1" "3" "Rain"
"1" "3" "Snow"
"1" "2" "Rain"
Now I would like to write a recursive query that goes hour by hour selecting the top row. The top row will always include the description with the highest occurrence (count) for that time interval or in case of a tie, it will still chose the top row.
Here's my first attempt:
With recursive
temp_table (counter, hour, current_Weather_description) as
(
SELECT count(*) as counter,
CASE WHEN strftime('%M', time_stamp) < '30'
THEN cast(strftime('%H', time_stamp) as int)
ELSE cast(strftime('%H', time_stamp, '+1 hours') as int)
END as hour,
current_weather_description
FROM weather_events
GROUP BY strftime('%H', time_stamp, '+30 minutes'),
current_Weather_Description
order by hour desc
),
segment (anchor_hour, hour, current_Weather_description) as
(
select cast(strftime('%H','2016-01-20 10:14:17') as int) as anchor_hour,
hour,
current_Weather_Description
from temp_table
where hour = anchor_hour
limit 1
union all
select segment.anchor_hour-1,
hour,
current_Weather_Description
from temp_table
where hour = anchor_hour - 1
limit 1
)
select *
from segment
From playing around with the query it seems it wants my recursive members "from" to be from "segment" instead of my temp_table. I don't understand why it wants me to do that. I'm trying to do something similar to this example, but I would like only 1 row from each recursive query.
This is the result I desire {count, hour, description}:
"1" "10" "Cloudy"
"2" "9" "Clear"
"2" "8" "Rain"
"2" "7" "Clear"
"2" "6" "Clear"
"1" "5" "Clear"
"1" "4" "Clear"
"1" "3" "Rain"
"1" "2" "Rain"

This can simply be done with another GROUP BY:
WITH
temp_table(counter, hour, current_Weather_description) AS (
...
),
segment(count, hour, description) AS (
SELECT MAX(counter),
hour,
current_Weather_description
FROM temp_table
GROUP BY hour
)
SELECT count, hour, description
FROM segment
ORDER BY hour DESC;
(In SQLite, MAX() can be used to select entire rows from a group.)
