A late summer deluge caused some very localized yet extensive flooding near Sault Ste. Marie Monday night into the early hours of Tuesday.
A warm front has lifted across the region as of Tuesday morning. As that warmer air arrived, thunderstorms blew up over Lake Superior Monday evening and just brushed the far northern reaches of the Eastern Upper Peninsula with a very sharp contrast from flooding rains to areas that saw none at all. Radar and spotter reports indicate anywhere from 2.50" up to 5.00" of rain fell in a short period of time.
Sault Ste. Marie broke a daily rainfall record for September 9th with 2.56" of rain Monday. That shattered by more than an inch the previous record of 1.54" set in September of 2001.
We did receive reports of some streets flooding in the city of Sault Ste. Marie with numerous roads washing out overnight on Sugar Island including 1 1/2 mile Rd. along with Westshore Drive. Hilltop Rd. was also washed out on the island.
While the Eastern U.P. will remain on the cloudier side of things Tuesday with high in the 70's to near 80F, it will be much different across Northern Lower Michigan. With this area firmly entrenched in the warm air, temperatures will skyrocket with temperatures jumping well into the 80's and even low-90's Tuesday. Our warmest spots will be south/east of a line from Rogers City to Traverse City with temperatures at places like Traverse City, Houghton Lake, Clare, Alpena, and Big Rapids spiking to 90F if not a little higher.
It will not be long lived however, as a cold front will cross the area Tuesday night. That frontal boundary will sweep in a few showers/thunderstorms over Lower Michigan Tuesday night. Temperatures then take a dramatic downward turn by the end of the week. Expect 70's Wednesday, 60's Thursday, and only upper-50's Friday.
