Another factor contributing to this unusual summer Florida drought is the periods of excessive heat. However, the west-central Florida Peninsula continues to see a lack of summer sea breeze thunderstorms and a persistence of drought of varying intensity. The majority of the Southeast is drought-free with above normal precipitation for most areas dating back 90 and 180 days.

Based on 30 to 90-day SPI, D0 was added to Nantucket and Martha’s Vineyard in southeastern Massachusetts. Recent rainfall of more than 1.5 inches led to a reduction of D0 across northern West Virginia. Heavy rainfall (locally more than 3 inches) led to the removal of D0 in central New York, while D0 and D1 continues on Long Island. However, long-term indicators continue to support abnormal dryness (D0) and moderate drought (D1) along and to the west of I-95. NortheastĪ 1-category improvement was made in the DC/Baltimore areas after more than 1.5 inches of rainfall. Short-term drought expanded this past week across parts of the Hawaiian Islands. On August 7, a severe weather outbreak with heavy rainfall affected the East. Farther to the north, drought continues to intensify across Wisconsin. The wet start to August resulted in improving drought across parts of the Corn Belt. During the first week of August, parts of Missouri received 5 to 10 inches (locally more) of rainfall. Frequent rounds of heavy rainfall occurred from the central Great Plains southeastward to the middle Mississippi Valley. The Monsoon remains suppressed with increasing short-term drought across Arizona, New Mexico and southwest Colorado. The persistence of this pattern led to rapidly developing and intensifying drought across Texas and the lower Mississippi Valley. Weekly temperatures (August 2 to 8) averaged more than 6 degrees F above normal across portions of Louisiana, Texas, and southern New Mexico. A strong area of mid-level high pressure, anchored over the southern tier of the country, continued to promote above-normal temperatures and mostly dry weather across the Rio Grande Valley, Texas, and the lower Mississippi Valley.
