This Week’s Drought Summary

This U.S. Drought Monitor week saw continued improvements in drought conditions as a large-scale, low-pressure system last week delivered moderate-to-heavy precipitation accumulations ranging from 2 to 7 inches leading to widespread improvements across portions of the South, Southeast, Mid-Atlantic, and the lower Midwest. For October, these regions saw well-above-normal precipitation that has helped alleviate drought conditions, especially in the Southeast. Out West, generally dry conditions prevailed with the exception of some mountain snow showers in the central and northern Rockies of Montana, Wyoming, and Colorado. In California, fire-weather conditions improved allowing firefighters in southern and northern California to help contain several large wildfires. According to the NOAA National Centers for Environmental Information (NCEI), the contiguous U.S. experienced its 21st coolest and 8th wettest October on record…

High Plains

On this week’s map, no changes were made across the region. For the week, the entire region was relatively dry with below-normal temperatures. Average temperatures ranged from 2-to-20 degrees below normal with the greatest negative anomalies observed in north-central and eastern Wyoming as well as eastern Colorado. According to NOAA NCEI, the Northern Rockies and Plains Climate Region experienced its 4th coolest and 26th wettest October on record. Additionally, the region had its wettest 3-month (Aug-Oct 2019), 9-month (Feb-Oct 2019), and 12-month (Nov 2018-Oct-2019) periods on record…

West

On this week’s map, no changes were made in the region. An on-going assessment of the abnormally dry conditions in California (since the beginning of the wet season) is currently underway by the U.S. Drought Monitor and the California Drought Coordination Team in order to ascertain the spatial extent and possible impacts being observed across the state. From a hydrologic perspective, despite below-normal precipitation during the past 60 days, nearly all of California’s major reservoirs are currently at or above historical averages for this time of year. Elsewhere in the region, portions of the central and northern Rockies received some snow shower activity during this past week. According the NWS NOHRSC’s regional snow analyses, 68.8% of the Northern Rockies and 59.7% of the Central Rockies are currently covered by snow. Additionally, the NRCS SNOTEL network is showing above-normal Water Year to Date (Since Oct 1) precipitation (liquid and frozen) in the mountains of northeastern Oregon, central Idaho, western Montana, northern Wyoming, and north-central Colorado. Elsewhere, stations are reporting below-normal precipitation for the same period. According to NOAA NCEI, the West Climate Region experienced its 11th driest and 19th coolest October on record while the Northwest Climate Region had its 49th driest and 2nd coolest October…

South

One this week’s map, recent rainfall across eastern portions of Texas, Arkansas, Louisiana, Mississippi, and Tennessee led to continued widespread improvement in conditions. Rainfall accumulations across the region ranged from 1 to 8 inches with the heaviest accumulations observed in Mississippi. This week’s precipitation improved soil moisture and streamflows leading to one-category improvements in areas of Severe Drought (D2), Moderate Drought (D1), and Abnormally Dry (D0). In portions of southern, central, and western Texas, dry conditions prevailed leading to some minor expansion of drought. As a region, the South experienced its 23rd wettest October on record, while at a state level Mississippi experienced its wettest October on record. For the week, average temperatures were below normal across the entire region with the greatest negative anomalies observed across the northern half of Texas and western Oklahoma where temperatures were 10-to-20 degrees below normal. As a region, the South Climate Region had its 36th coolest on record for October…

Looking Ahead

The NWS WPC 7-Day Quantitative Precipitation Forecast (QPF) calls for moderate-to-heavy accumulations ranging from 1 to 4 inches across a swath extending from northern Texas to Kentucky later this week. Further south, light-to-moderate accumulations (1-to-2 inches) are expected along the Gulf Coast and in south Texas. Along the Great Lakes and the Northeast, periods of precipitation (accumulations generally <1 inch liquid), including some heavy lake-effect snowfall, are expected. Out West, primarily warm and dry conditions will prevail with the exception of northern portions of the Pacific Northwest and northern Rockies that may see periods of mountain snow. The CPC 6–10-day Outlook calls for a high probability of above-normal temperatures west of the Rockies while areas east of the Rockies are expected to be below normal. In terms of precipitation, there is a moderate-to-high probability of below-normal levels across most of the West including the Intermountain West, Great Basin, California, and the Pacific Northwest while there is a moderate probability of above-normal precipitation in eastern Montana and western portions of the northern Plains. Likewise, above-normal precipitation (moderate probability) is expected in the southern tier from Texas to Florida and extending up the Eastern Seaboard.
