This Week's Drought Summary (12/20)

December 21, 2017

Snow fell across most of the Northeast, but it was dry across most of the contiguous United States, with much of the country receiving less than 0.10 inch of precipitation and many areas receiving nothing at all. Part of the South, from eastern Texas to western Alabama, did receive more than an inch of rain, with locally heavier amounts, which helped improve dry conditions. Temperatures were generally below average across the eastern third of the U.S. and above average across most of the western two-thirds. Warmth was notable in eastern Montana and the Dakotas where temperatures were up to 20°F above normal. It was around 5-10°F above normal in the central U.S., an area that continued to see dry conditions this past week. In general, drought expanded across parts of the West, Southern Plains, Midwest, Southeast, and Mid-Atlantic and contracted across part of the South.
