U.S. Drought Monitor Update for July 19, 2016

July 19, 2016, U.S. Drought Monitor Map

According to the July 19, 2016, U.S. Drought Monitor, moderate to exceptional drought covers 18.8% of the contiguous United States, an increase from last week’s 17.7%. The worst drought categories (extreme to exceptional drought) also increased from 2.6% last week to 2.9%.

A subtropical high pressure ridge dominated the Southern Plains to Southwest this U.S. Drought Monitor week, keeping the weather hot and dry. An upper-level low pressure trough held sway across the Pacific Northwest, keeping temperatures cooler than normal in the Northwest to Northern Plains. This circulation pattern kept the storm track across the northern tier states, with fronts and low pressure systems bringing areas of above-normal rainfall to parts of the Northern and Central Plains and Midwest. Some of the fronts managed to penetrate into the Southeast, bringing some areas of rainfall. But, dry weather still dominated in parts of the Northern Plains, most of the Northeast, and a large part of the Southeast.
