What yer gonna need is your everyday WEATHER ROCK!
Tells time and weather both.
What ya do is get a rock, a rather large rock, and put out in the yard free of overhead structure.
When the rock is dry the weather is dry.
When the rock is wet the weather is rainy.
When the rock is cool the temperature is going to be cool.
When the rock is warm the temperature is going to be warm.
When the rock has sunshine on it, it is daytime.
When the rock is dark it is nighttime.
Got it all covered.
