August of 2023 was 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.
