U.S. Drought Monitor Update for August 9, 2016

August 9, 2016 U.S. Drought Monitor Map

According to the August 9, 2016, U.S. Drought Monitor, moderate to exceptional drought covers 21.8% of the contiguous United States, an increase from last week’s 21.1%. The worst drought categories (extreme to exceptional drought) decreased slightly from 2.9% last week to 2.8%. 

This USDM week saw the continuation of the battle between a subtropical high pressure ridge across the southern tier States and the jet stream and storm track across the northern tier States. But the weather pattern was complicated by a low pressure center which developed across northern Florida and slowly moved westward along the Gulf of Mexico coast later in the week, by a frontal system which sagged into the Southeast and stalled out, and by a resurgence of monsoon showers over the Southwest.  As a result, weekly precipitation was above normal in the Southwest and along the stalled front and Gulf Low, and drier than normal across the rest of the West, much of the Plains, and Great Lakes to Northeast.  Temperatures were warmer than normal from the Southern Plains to Great Lakes and cooler than normal across much of the West to Central and Northern Plains.
