Warm, moist tropical air during the day on Thursday helped to spark severe storms that began to develop during the late afternoon hours. These storms continued through the evening before the severe threat switched over to a flooding threat during the overnight hours. Heavy rain continued to fall across much of the area throughout the overnight as a cold front pushed eastward. Numerous trees and power lines were reported down south of M-59 while northwest/northern areas dealt with significant flooding. Over 6 inches of rain fell across the Tri-Cities region. June monthly rainfall total at Saginaw ended up being 10.76 inches, the most on record for June.
