West, Northwest and Southwest
Light precipitation fell in parts of Wyoming, southern Utah, much of Arizona, New Mexico and Colorado. Average temperatures were generally 2-6 degrees F below normal in those areas. Some readings were as much as 8-10 degrees F below normal. Based on 30 and 60 day departures, D0 was expanded in the south and an expansion of D1 was made in western Montana and eastern Idaho. In Colorado, a 1-cat improvement was made in the southwest based on 30- and 60-day percent of normal precipitation. The Southwest monsoon produced another round of precipitation for eastern New Mexico during the period. But it was not enough to affect drought conditions there. It is the dry season, so little to no precipitation is not surprising in California. Drought conditions there will remain status quo for the time being.
