Read the full account →A midlevel Pacific low pressure system undercut the area of high pressure over the Great Basin as it dropped into the Northern Rockies. Monsoon moisture increased across the region with precipitable water values ranging from 125 to 175% of normal across the Four Corners.
Read the full account →Monsoon moisture increased across the region as the area of high pressure shifted towards the Southern Plains. The abundance of moisture fueled numerous showers and thunderstorms during the afternoon and evening hours. Storms were slow moving and produced heavy rain.

Read the full account →The moist airmass that was in place at the end of July, remained in place into August, with widespread afternoon thunderstorms across Utah. While flash flooding and severe thunderstorms were reported in both northern and southern Utah, the flooding primarily occurred across the…
Read the full account →Monsoon moisture moved into southern and central Utah in mid-July, allowing thunderstorms to become more widespread each afternoon. This moisture, combined with the fact that many of these thunderstorms were slow moving, led to flash flooding in many locations across southern…
Read the full account →Additional moisture moved into Utah in early September, helping to initiate scattered showers and thunderstorms, with some reports of flash flooding on the 5th through 7th.
Read the full account →The daily potential for flash flooding was relentless through the middle of July, with multiple flash floods during this period resulting in property damage.
Read the full account →A largely ridge-dominated pattern persisted, resulting in anomalously warm temperatures. These hot temperatures resulted in at least one instance of a heat related fatality.
