This Week's Drought Summary (1/9)

January 9, 2020


Over the past week, primarily light to moderate precipitation fell from east Texas northeast through New England. Heavier precipitation amounts of 2 to 6 inches were embedded within the larger precipitation swath, affecting areas from southwest Louisiana to the southern Appalachian Mountains. Heavy precipitation amounts, including mountain snow, fell in the Pacific Northwest and in the central and northern Rocky Mountains. Warmer than normal temperatures also covered most of the continental U.S., with the warmest conditions (compared to normal) taking place in the northern states. In the West, many areas that received significant mountain snow in the past few weeks saw an improvement in drought conditions, while areas that missed out on the snow or still had significant precipitation deficits did not see improvements to their drought depiction. Improvements or degradations in conditions east of the Rocky Mountains were primarily in response to significant precipitation occurring, or lack thereof, over the past several weeks. Degradations made in parts of central and southern Texas also occurred due to high evaporative demand and the associated negative impacts on soil moisture.
