This Week’s Drought Summary

As Tropical Storm Isaias made its way up the east coast, many areas in the Northeast were beneficiaries of good precipitation amounts, but others missed out completely. In typical summer fashion, rains were hit and miss across the country, with the West and into the southern Plains as well as most areas of the South mainly being missed. Mixed precipitation was recorded through the Plains and Midwest as well as portions of the Southeast. A strong derecho ripped across the Midwest on August 10th with over 100 mph straight line winds doing damage to crops and property. Temperatures were cooler than normal over much of the Midwest and High Plains, with portions of Missouri and Illinois 6-8 degrees below normal for the week. Temperatures were near normal along much of the east coast and 6-8 degrees above normal over west Texas and into New Mexico…

High Plains

Spotty precipitation was common through the area, with dry conditions through most of Kansas and Nebraska and above-normal precipitation in central North Dakota, central to southeast South Dakota and pockets of northeast Wyoming and northwest South Dakota. Temperatures were cooler than normal over the eastern portions of the region to normal to slightly above over the western portions. Changes to drought status this week include an expansion of severe drought in both western and eastern Nebraska, expansion of moderate drought and abnormally dry conditions in central Nebraska, expansion of moderate drought in western Nebraska and some improvement of abnormally dry conditions in the central portion of the state. Southeast Kansas saw improvements to abnormally dry and moderate drought conditions this week. In South Dakota, abnormally dry and moderate drought conditions were expanded in the northeast while there was improvement to abnormally dry conditions in the east. North Dakota had some improvements to moderate drought and abnormally dry conditions over the north central portion of the state and expansion of moderate drought and abnormally dry conditions over the central area. Wyoming had an expansion of moderate drought and abnormally dry conditions over the southeast while portions of eastern Colorado had improvements to severe and extreme drought…


Much of the West was dry this week, with just some spotty summer rains along the coast and very spotty monsoonal rains in the Southwest. Temperatures were cooler than normal over southern Nevada and southern California as well as into the Pacific Northwest and northern Rocky Mountains. This was not the case in Arizona and New Mexico, where temperatures continued to be well above normal with departures of 3-5 degrees above normal. In Oregon, severe and extreme drought conditions were expanded slightly to account for the continued dry conditions throughout the current water year. Southern Utah and western Colorado had severe and extreme drought expand this week along with moderate drought in northeast Utah and northwest Colorado. Extreme drought was also expanded over southeast Nevada. Extreme drought was improved over southern Colorado in response to some rains in the area easing conditions. Moderate to severe drought was also expanded over most of central Colorado. Abnormally dry conditions were expanded over western Wyoming as well…


Temperatures were 2-4 degrees below normal over much of Oklahoma, Arkansas, western Mississippi and Tennessee, northern Louisiana, and portions of northeast Texas. Temperatures were warmer than normal from central Texas into the west and Panhandle, where departures were 3-5 degrees above normal. Outside of areas of Oklahoma, western Arkansas and north Texas, it was a dry week over the region. Coupled with the warm temperatures, much of the state of Texas had degradation shown this week. Improvements were shown over the Oklahoma and Texas panhandles as well as in eastern Oklahoma. Abnormally dry conditions and moderate drought were expanded over northeast Arkansas, with abnormally dry conditions expanded over western Mississippi. Tennessee had improvements to abnormally dry conditions in the east, but saw expansion of those conditions in the south along with the introduction of some moderate drought…

Looking Ahead

Over the next 5-7 days, it is anticipated that much of the area west of the Continental Divide will be dry. Areas of the central plains and upper Midwest will see an active pattern for precipitation while much of the area of the southeast into the Mid-Atlantic should also see the greatest precipitation during the period. Temperatures during this time should be well above normal over the West, with departures of 6-9 degrees above normal. In the areas anticipated to see the most precipitation, from the northern Plains to the Mid-Atlantic, temperatures will be cooler than normal as a trough digs into the region out of Canada.

The 6-10 day outlooks show a divide in temperatures, with the western half of the United States, including Alaska, having above-normal chances of seeing above-normal temperatures and the eastern half having above-normal chances of below-normal temperatures. A drier than normal outlook is expected over much of the country, with the area having the greatest probability of below-normal precipitation centered on the Midwest. Areas of the Mid-Atlantic south to Florida have the greatest chances of having above-normal precipitation.
