Names for the Weather Today
A generator that produces one weather report in neighbor-language.
Run it. You get one report. Run it again, you get a different one.

# picks and combines but does not dilute.

四月五日，星期日

光线压得很低，正午也是。车开得比平时慢，没有什么原因。
不管怎样，带件毛衣。

天空像被水洗过。砖墙上的光一个小时没有动过。
不管怎样，带件毛衣。

四月五日，星期日

今天的空气是松的那一种。鸽子举止如常，这一点反倒值得一记。
不会下雨，但带上件有兜帽的东西。

光里有一种稀薄。猫进来，出去，又进来了。
计划别订死。
