The episode as NWS GJT wrote it up.
Drought conditions remained unchanged across most of eastern Utah in March as below normal precipitation continued to impact the region. The eastern Uinta Basin received close to normal precipitation at 0.68 inches, but most of this fell with one storm early in the month. Areas of southern Utah didn't fare as well with a deficit of liquid precipitation close to 0.75 of an inch near Moab. As a result severe to moderate drought conditions remained in place through the month.
