Summer of 2023 Weather Review

The summer of 2023 started out cool and wet, especially across southeast Colorado, where several storm systems brought record precipitation in the month of June. Colorado Springs recorded 9.62 inches of precipitation through the month of June, which not only set a record for the most precipitation in the month of June, but also becomes the wettest month ever in Colorado Springs, surpassing the 8.13 inches recorded in May of 2015.

July was "A Tale of of Two Cities" across southern Colorado, with dry and warm conditions prevailing across south central Colorado, while cooler and unsettled weather prevailed across southeastern Colorado. Alamosa received 0.01 inches of precipitation through out the month July, making July of 2023 the driest July on record in Alamosa, while Campo and Walsh Colorado received 6.33 inches and 6.39 inches respectively, in July, becoming the 5th and 4th wettest July's respectively. Unfortunately, the unsettled weather across the southeast plains also brought bouts of severe weather, with large hail of 2 to 4 inches in diameter, flash flooding, strong damaging wind gusts and tornadoes all observed across southeast Colorado through out the month of July.

August was a generally warm and dry month across the region, with upper level ridging parked across the southern High Plains through the Desert Southwest and Great Basin through the first half of the month, keeping monsoonal moisture south and west of the Rockies. This anomalous weather pattern kept eastern Colorado in northwest flow and continued bouts of severe weather, including August 5th, when several funnel clouds where reported across El Paso county. The upper ridge broke down through the end of the month, bringing a few bouts of monsoonal moisture and locally heavy rainfall to portions of south central and southeast Colorado.
