Change is the keyword in the weather outlook for the next week, with a distinct warming trend underway with some temperatures in the mid- to upper 80s in parts of the Plains to start the week. Aside from a quick cooldown in the nation’s center with some snowfall chances in the northwestern High Plains around midweek, the trend toward generally warming temperatures will accelerate spring fieldwork and planting in much of the country. But they won’t last; low-pressure troughs connected to cold air masses around the Artic could cool temperatures in some areas of the Pacific Northwest and northern Plains into next week. Those “brief shots of cold air” won’t cause major long-term cooling and the planting window will likely remain wide-open through at least mid-April, according to the latest outlook. See more here.
