#Drought news: No change in depiction for #Colorado

Click here to go to the US Drought Monitor websites. Here’s an excerpt:

Summary

Please note the Drought Monitor depicts conditions valid through Tuesday morning, 8 a.m., EDT (12 UTC); any of the recent locally heavy rain which fell after Tuesday morning (June 28) will be incorporated into next week’s drought assessment. For the 7-day period ending June 28, despite pockets of locally heavy rain (which led to catastrophic flooding in parts of West Virginia), above-normal temperatures and below-normal rainfall caused dryness and drought to expand or intensify across portions of the central and eastern U.S. Nationally, the percent of soil moisture rated poor to very poor climbed 5 points over last week to 31 percent (as of June 26, according to USDA-NASS), which was 14 percentage points higher than last year at the same time…

Northern Plains

Heat and dryness caused drought conditions to intensify locally. While showers were noted over northern-most portions of the region for a second consecutive week, drought intensified and expanded farther south. Areas hardest hit by the heat and dryness extend from northeastern Wyoming into western South Dakota. Severe Drought (D2) was expanded to encapsulate areas that have received less than 60 percent of normal (locally less than 50 percent) rainfall over the past 90 days. Furthermore, satellite-derived vegetation health imagery as well as rainfall data indicated conditions have rapidly worsened to Extreme Drought (D3) in a small area immediately adjacent to the Black Hills. Farther east, Abnormal Dryness (D0) also expanded across southern portions of South Dakota where 60-day rainfall was near or below 60 percent of normal. Likewise, D0 was expanded over northern Wyoming where similar short-term deficits were noted…

Central and Southern Plains

While much of the region remained mostly drought free, excessive heat (100°F or greater) coupled with pronounced short-term dryness necessitated the introduction of Moderate Drought (D1) in central Oklahoma. Over the past 60 days, this new D1 area has reported 30 to 55 percent of normal rainfall (locally less); rapid drought intensification in this area is likely if rain does not materialize soon…

Texas

Texas remained free of drought following a much-wetter-than-normal May. However, recent 100-degree heat and short-term dryness have raised concerns over the potential for a return to “flash” drought (rapidly occurring drought caused by a combination of dryness, high heat, and strong winds)…

Western U.S.

Due to the onset of the West’s “dry season”, changes to the region’s drought depiction during the summer months are usually minor, if any. However, Abnormal Dryness (D0) was expanded across northern Idaho to reflect declining soil moisture supplies brought on by a lack of rainfall over the past 60 days. Protracted short-term dryness — despite generally cooler-than-normal weather — has also been noted along the northern Pacific Coast. These more northerly coastal ranges typically receive some precipitation during the latter half of spring and early summer, and 60-day rainfall has tallied 30 to 50 percent of normal (deficits of 2 to 6 inches) from northwestern California to the Puget Sound…
