U.S. Drought Monitor Update for November 15, 2016
According to the November 15, 2016, U.S. Drought Monitor, moderate to exceptional drought covers 30.1% of the contiguous United States, an increase from last week’s 27.4%. The worst drought categories (extreme to exceptional drought) also increased from 5.0% last week to 6.4%.
A large upper-level ridge of high pressure dominated the Lower 48 states this U.S. Drought Monitor week, keeping much of the country warmer and drier than normal. Low pressure troughs moving in the jet stream flow brought precipitation to the Pacific Northwest, northwest California, and the Northern Rockies; parts of Texas and the Gulf of Mexico Coast; and the coastal Southeast to Mid-Atlantic states and eastern Great Lakes.
But, except for Texas and a few areas in the coastal Carolinas, even with the precipitation, the week was drier than normal. The continued and prolonged dryness in many areas resulted in expanding and intensifying drought, especially in the Central to Southern Plains, Lower Mississippi Valley to Ohio Valley, and Southeast to Northeast.
