The best news in the weather forecast is the fact that it still looks to be frost-free in the Midwest (and in the Northern Plains and Canadian prairies for that matter) through the end of next week and quite possibly even longer than that. A slow-moving, closed, upper-level low pressure system that will be developing at the end of this week and quite possibly lasting well into next week will be largely responsible for the lack of freezing temperatures, as it will prevent the needed delivery of abnormally cold air in the middle part of the Nation (something obviously needed for a mid-September frost). That said, the weather system in question is not going to create especially favorable weather for crops trying to mature, and creates a lot of weather forecast headaches as well. When we see the upper-level low pressure system develop at the end of this week, temperatures across much of the Nation’s midsection will drop below normal…not due to especially cold air, but due to a lot of cloud cover and some rainfall.
My best guess right now is that rains from this system will cover the Plains and areas of the Corn Belt to the west of the Mississippi River by Saturday morning, and spread into the rest of the Corn Belt and the Delta for the weekend. I say that this is my “best guess” as these closed, upper-level low pressure systems are often times poorly handled by weather forecast models, and I think that this is going to be another classic case of this. Once it gets established at the end of this week, the weather models are in big disagreement on where the system goes, and how long it lasts. One can find models that move the system out of the region early next week…and others that keep the system alive and well in the Midwest through the end of the ten-day forecast. If the former scenario is correct, we will dry things out in the Midwest next week and probably warm things up. If the latter scenario is correct, then we will keep temperatures cool and keep a daily threat of rain in the forecast for parts of the region.
