Widespread precipitation amounts of more than 0.5 inch along with much cooler temperatures resulted in improvements throughout Minnesota. D1 was expanded across central and eastern Kentucky along with southwestern Ohio based on 30 to 90-day SPI and soil moisture. D1 was slightly expanded across southwestern Indiana due to increasing short-term dryness. A slight reduction in D0 and D1 occurred in parts of central Illinois that received 0.5 to 2 inches of precipitation. This heavy precipitation extended south into northwestern Indiana and northeastern Illinois where a 1-category improvement was also made. MidwestĪbnormal dryness (D0) and moderate short-term drought (D1) were increased to the east of Lake Michigan, while recent precipitation (more than 2 inches) resulted in a 1-category improvement across southern lower Michigan. Increasing short-term dryness led to an expansion of abnormal dryness (D0) and moderate drought (D1) across Tennessee. The 90-day SPEI also supported an expansion of D4 across northeastern Louisiana. Impacts in Mississippi include poor pasture conditions, soybean and peanut losses, and cattle sell offs. Based on 90-day SPEI, an expansion of D2-D4 was made to parts of Mississippi. Drought coverage and intensity across Texas peaked in early September when 85.68 percent of the state was covered with drought (D1 or higher) and two-thirds of the state was designated with severe (D2) to exceptional (D4) drought.

For areas that received more than 3 inches of precipitation and there was support from the NDMC’s drought blends, a 2-category improvement was justified across southwestern Arkansas, northeastern Texas, and the Texas Gulf Coast. SPIs at multiple time scales, soil moisture, and 28-day average streamflows were also factors in determining where to depict the improvements. SouthĪ broad 1-category improvement was made to southern Arkansas, northwestern Louisiana, southeastern Oklahoma, and eastern to central Texas where more than 1.5 inches of precipitation occurred this past week. D2 was expanded slightly east across the Florida Panhandle, while moderate short-term drought (D1) was added to north-central Florida with support from the 30-day SPI, soil moisture, and 28-day average streamflow. Severe drought (D2) was expanded southwest across western Virginia based on 6-month SPI and river levels below the 10th percentile. Given the lack of precipitation during the past 4 to 6 weeks, abnormal dryness (D0) expanded north into southwestern and south-central Virginia. Based on these short-term indicators, severe drought (D2) coverage was increased across parts of Alabama and added to the northwest corner of Georgia. The drought expansion and intensification was based on 30 to 60-day SPI/SPEI, NDMC’s short-term blend, and soil moisture. SoutheastĪnother week of 1-category degradations were necessary for parts of Alabama, Georgia, and the Carolinas. No changes were made to the Mid-Atlantic, while heavy rainfall this past week maintained excessive wetness across New England. Conversely, heavy precipitation (1 to 2.5 inches) led to a 1-category improvement across western New York. Increasing short-term precipitation deficits led to a slight increase in D0 (abnormal dryness) and D1 (moderate drought) across western West Virginia. Drought continues to intensify across parts of Maui and the Big Island. Heavy rainfall, associated with Tropical Storm Philippe, resulted in improving drought for eastern Puerto Rico. Following a wet September, minor improvements were warranted for parts of Washington. Father to the south, short-term drought continued to expand north and east across the Southeast.

As the cold front progressed eastward, drought-easing rainfall overspread parts of Illinois, northern Indiana, southern Michigan, and western New York. The first frost or freeze of the fall affected the Northern to Central Great Plains on October 7. to start October, the cold front ushered in much cooler temperatures from October 5 to 7. Following anomalous heat across the central U.S.

The most widespread improvements were made to southern Arkansas, northwestern Louisiana, southeastern Oklahoma, and eastern to central Texas where more than 2 inches of precipitation was observed this past week. A strong cold front resulted in moderate to heavy precipitation across the Great Plains, Ozarks, and western Gulf Coast during the first week of October.
