Why does the weather do this?

Every year it seems that the end of March and the beginning of April is beautiful weather. More often than not, you see farmers itching to start running the first week of April if not sooner anymore. The weather and conditions are usually fit at this point in time for fieldwork to begin. However, it always seems towards the end of April, it turns off extremely cold and wet. This makes it a difficult decision to decide whether to being fieldwork. Do you risk the weather and try to get the benefits of the early start, or play it safe and risk running behind? Ultimately from experiences I have seen, I would say it’s worth the risk to try and get the benefits of the early spring. It seems the crops today can withstand these conditions and provide excellent benefits making it much worth the risk of beginning early.
