About 4:30 PM today it got dark enough in the house to turn the lights on. Clouds built up steadily all day and it began to rain about 4:30 PM.
We didn't have cumulus clouds today but layer after layer of clouds.
Our forecast predicted rain for this afternoon , evening , night and tomorrow. So you know that a major system is moving into the area. The radar map show a large cloud system slowly moving north from Montana and curving in toward the Rocky Mountains. This is when we get a major rainfall. As I said in a post before, the air mass has to rise when it hits the Rockies and when it rises it cools and dumps the rain on us. This system has come over the mountains of the north western states. Somehow much of the moisture remained in the system and it is released over us.
When we get west winds we don't get rain. The air moves over the Rockies and all the moisture falls on the west slopes of the Rockies.
So you see at 4:30 PM this afternoon we had a huge build up of cloud which was full of moisture and some of it fell on us. With a very thick cloud layer much sunlight is blocked so we have to sit in the dark or turn the lights on.
Since I like rain I'm fine. I like going out for a long walk in the rain. I think I'll have a good chance to walk in the rain tomorrow.
