Unfortunately, with the exception of a few locations in the Carolinas, the heaviest rain fell in areas lacking any dryness. SoutheastĪ trailing frontal boundary, associated with a storm system moving across the Great Lakes and Northeast toward the end of the week, resulted in pockets of heavy rainfall in excess of 2 inches across the central Gulf Coast, parts of the Coastal Plain of the Carolinas, and the Southern Appalachians. 7-day average stream flows have fallen below the 10th percentile of the historical distribution for this period and soil moisture continues to decline. In areas that experienced below average 7-day rainfall, expansion of abnormally dryness (D0) and moderate drought (D1) conditions is warranted, particularly across southern portions of the Northeast. Otherwise, the storm system did little to improve antecedent dryness, acting only to halt ongoing deterioration, with the help of below average maximum temperatures for this week. NortheastĪ storm system developed over the Midwest during the weekend and moved across the Northeast Monday into Tuesday bringing heavy rainfall to parts of the interior Northeast, warranting targeted improvements to the drought depiction in portions of northeastern Pennsylvania and interior New England. In areas that received below normal rainfall this week, drought worsened, as rainfall deficits continue to increase. From the eastern Great Plains to the Eastern Seaboard, 7-day rainfall surpluses are more scattered in nature, leading to only modest improvements in areas seeing the heaviest amounts. Improvements are mainly confined to the western Great Plains, where widespread 7-day rainfall totals exceeded 200 percent of average for the week, further adding to short-term precipitation surpluses. There is a mix of improving and worsening drought conditions across the Great Plains. The exception is the Pacific Northwest, where below normal precipitation and above normal temperatures resulted in worsening drought conditions along the northern Cascades. Above normal precipitation and below normal temperatures resulted in another week of targeted improvements across portions of the Intermountain West, adding to recent precipitation totals that have continued to improve long-term drought conditions.
