#Drought News: Cooler-than-average temperatures over parts of Colorado this past week

Click here to go to the US Drought Monitor website hosted by the Colorado Climate Center. Here’s an excerpt:


This week a southwesterly flow returned to the Southeast, ushering in a tropical like air mass that produced widespread precipitation across the region. Meanwhile, a strong upper level low developed in the Midwest, producing heavy rains, which prompted flash flood watches. Warm, dry air continued to dominate the West…

Northern Rockies / Plains and Northwest

Above-normal precipitation effected western South Dakota, southeast Montana and northeast Wyoming during the period. Temperatures in those areas were running as much as 6 degrees above normal. As a result of the recent rains, the remaining D0 was removed in Nebraska and South Dakota. Warmer-than-normal temperatures and large precipitation deficits continued to hold their grip on Washington and Oregon this week. D3 conditions were expanded in Washington where hay growers are suffering from millions of dollars in losses due to the ongoing warm, dry conditions. It was also reported that pear and apple trees are stressed along with hops…


The monsoon season brought some good rains into Arizona prompting drought improvements in southeast Arizona. Cooler-than-average temperatures were seen in portions of Colorado and Utah. It was reported that eastern Colorado had started to dry out, but thanks to the spring moisture and cooler than normal temperatures for much of the summer, evaporative demand has been lower than average. Consequently, the soils have been able to retain the moisture and prevent drought degradation. Temperatures for the period were generally warmer than average across the region. Drought was contracted in southeast Arizona and southwest New Mexico…


California continues to deal with its ongoing drought. Water managers and farmers are adapting their practices to help conserve water and reduce economic loss in the state. Temperatures in California were warmer than average in the south, gradually transitioning to cooler than average northwards. The only precipitation that fell during the period was in south and east Nevada…

Looking Ahead

During the next 6-10 days, the probability of cooler than normal temperatures are high in the Ohio and Tennessee River Valley’s extending into the Great Lakes and Midwest. Chances are likely that the rest of the country will experience warmer than normal temperatures, especially in the Northeast, Southeast, and Southwest.

Over the same period, precipitation associated with the large system centered over Wisconsin will move through the Great Lakes area. Further south, the precipitation will slowly move eastward and dissipate as the low pressure moves into Canada. Another, less powerful and dryer system will follow producing the heaviest precipitation in the Midwest. Ridging continues to hold its grip in the West while monsoonal precipitation may bring light drought relief in the Southwest.
