#Drought news: #Colorado is drought free

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

Summary

The USDM week (May 23‐30) was characterized by above normal precipitation across much of the Southeast and Mid‐Atlantic. Soaking rains fell in the eastern half of the country during the first half of the week, providing drought relief in the hardest hit areas of Georgia and northern Florida. By the time the system had moved out on May 27, much of the region had received more than double the rainfall (2 inches or more) of what is typically expected for the week. Drought and dryness continued in the High Plains, parts of the South and much of the Southwest. Temperatures across much of the country were at or below normal for the period. However, the Northwest was 5‐10 degrees above normal…

High Plains

Objective short‐term blends indicated conditions quickly deteriorating in the Dakotas and eastern Montana. Less than one‐half inch of precipitation has fallen (50 percent of normal) during the last 30‐ days and percentiles were in the D1‐D3 range. This prompted the expansion of both D0 and D1 in the area. Based on USDA’s crop progress report released on May 30, North Dakota’s pasture and range conditions are rated 21 percent poor to very poor while its topsoils and subsoils were rated at 36 percent and 23 percent, respectively. South Dakota’s pasture and range conditions are rated 26 percent poor to very poor and subsoils were rated at 38 percent and 39 percent, respectively. Montana’s pasture and range conditions are rated 17 percent poor to very poor while its topsoils and subsoils were rated at 34 percent and 20 percent, respectively.

In Colorado, cooler‐than‐normal temperatures have slowed the snow melt resulting in below average streamflow conditions in the Yampa, White and Colorado Rivers. Streams are particularly sensitive to these patterns as the flows normally begin to peak this time of year. The remaining snowpack across the region remains above normal across the Upper Colorado River Basins and eastern Colorado for this time of year. The small pocket of abnormal dryness in central Colorado is reflective of drier‐than‐normal areas of vegetation and soils…

West*

Temperatures in the West during the last 7 days have generally been 4‐8 degrees above normal. Coolerthan‐ normal temperatures were observed for the central California coast, southeast Idaho and northeast Utah. Drought changes in California remain curbed as the dry season marches on. Further north, D0 was expanded in eastern Montana. Percent of normal precipitation is 5 percent or less in the area during the last 14 and 30 days.

Looking Ahead

For days 1‐3 (June 1‐4) the heaviest precipitation will be confined along the Gulf Coast, much of Oklahoma, eastern Missouri and northern Illinois. Parts of Florida are also forecasted to receive 1 inch of rain or more. Meanwhile, temperatures will begin warmer than normal in the West and cooler than normal in the Midwest. The abnormal warmth will quickly spread eastward affecting the Northern Plains on June 2 and the Midwest by June 3. By June 4, much of the CONUS will be warmer than normal with a few exceptions in the Deep South and parts of the Northeast.

According to NOAA’s 6‐10 day outlook, odds are in favor of warmer than normal conditions west of the Rockies, while cooler than normal conditions dominate the east. Odds are in favor of below‐normal precipitation in the Northwest and Midwest while the probability of above‐normal precipitation is high along the eastern seaboard.
