Weather & Harvest Updates

The USDA’s December 5 bulletin reports heavy precipitation occurred in parts of the Pacific Northwest and drought-stricken Gulf coast states. Meanwhile, the upper Midwest finished the month with record low rainfall totals. Dry conditions persisted throughout much of the Plains regions as well as Central and Southern California and South Florida. In areas that permitted fieldwork, late planting of winter wheat and summer crop harvesting neared completion. Near or below normal average temperatures dominated much of the country this week as rising average temperatures moved in later in the week.
