Despite a mostly dry week across southern South Dakota, a reassessment of current indicators such as NDMC’s drought blends supported a decrease in abnormal dryness (D0) and moderate drought (D1) in that area. Increasing 30 to 60-day deficits along with support from SPIs at various time scales and the NDMC’s short-term drought blend, a 1-category degradation was made to northeastern Kansas and southeastern Nebraska.
Parts of Kentucky, southern Illinois, Minnesota, and Wisconsin had a 1-category improvement after heavy rainfall (more than 1.5 inches) the previous week. Based on NDMC’s short to long-term blends and soil moisture, extreme (D3) and exceptional (D4) drought was expanded across eastern Iowa. The largest areas of degradation were focused across Indiana and Ohio where many areas have received less than 25 percent of their normal precipitation during the past 30 days and soil moisture indicators continue to decline. MidwestĪ mix of degradations and improvements were made this past week across the Middle to Upper Mississippi Valley, Ohio Valley, and Corn Belt. Based on state recommendations and consistent with the NDMC drought blends, the extreme drought (D3) was slightly reduced across western Texas. Heavy rainfall (more than 2 inches) on October 2nd supported a 1-category improvement across the Oklahoma Panhandle and western Texas. Severe (D2) to exceptional (D4) drought persists across much of Mississippi and Louisiana, while drought of varying intensity affects the Southern Great Plains. Impacts in Mississippi include poor pasture conditions, soybean and peanut losses, and cattle sell offs. SouthĪ broad 1-category degradation was made to the Lower Mississippi Valley and Tennessee Valley as 30-60 day SPI/SPEI, NDMC short-term blend, soil moisture, and impacts supported expanding/intensifying drought. There was a slight northward expansion of D0 and moderate drought (D1) in Hillsborough and Pasco counties of Florida. Heavy rainfall prompted a removal of abnormal dryness (D0) along coastal northeastern Florida, while D0 expanded across the interior areas of northeastern Florida. Severe drought (D2) was introduced to the southwest corner of Georgia and expanded across the Florida Panhandle, supported by soil moisture and NDMC’s short-term blend. This recent dryness is even leading to much lower 28-day average streamflows. The largest 30-day precipitation deficits (3 to 5 inches) are centered across the Southern Appalachians. The drought expansion and intensification was based on 30 to 60-day SPI/SPEI, NDMC’s short-term blend, and soil moisture. SoutheastĪ broad 1-category degradation was necessary for much of Alabama, Georgia, and the western Carolinas. Despite near to above-average precipitation last month, longer-term precipitation deficits support a continuation of D0 and D1 across parts of southern Pennsylvania, Maryland, and eastern West Virginia. Severe drought (D2) was added to western New York, based on 60-day SPI and 28-day average streamflows below the 10th percentile. NortheastĪ drier-than-normal September (precipitation deficits of 2 to 4 inches) resulted in an expansion of abnormal dryness (D0) and moderate short-term drought (D1) across western parts of Pennsylvania, New York, and West Virginia.
Drought continues to worsen along the leeward side of Maui. Early fall precipitation began to ease drought along the coastal Pacific Northwest. A suppressed 2023 Monsoon led to intensifying drought across Arizona and western New Mexico. However, heavy rainfall at the beginning of October resulted in improvement for the Southern High Plains. Drought of varying intensity persists across the Middle to Upper Mississippi Valley and parts of the Great Plains. A drier-than-normal September led to an expansion of abnormal dryness (D0) and moderate short-term drought (D1) across the Upper Ohio Valley, Eastern Corn Belt, and western parts of Pennsylvania, New York, and West Virginia. The rapid onset and intensification of drought continued across the South with drought expanding northeast from the Lower Mississippi Valley to the Tennessee Valley and Southern Appalachians.
