The August 9th-11th Rain Event

 

A slow moving upper level low pressure system rotated across Southeast Michigan, bringing a prolonged period

of steady rainfall to much of the area, beginning Thursday the 9th and lasting through early Saturday morning the

11th. For much of the area, this rain provided relief from the moderate to severe drought which had gripped Southern

Michigan since June. However, some locations received too much rain and experienced flooding. Over these two days

most of southeast Michigan received between one and three inches of rain. However, the Saginaw Valley  received

between 3 and 8 inches and a few local spots along the M 59 corridor received 3 to 6 inches. Tri Cities airport (MBS)

had a two day rainfall total of just over 8 inches! Of this, 6.93 inches fell during Friday the 10th. This shattered the

previous 1 day record of 5.51 inches which occurred on September 10th, 1986 during one of the most extreme rain

events in recent history. Prior to this rainfall, Saginaw was on target to have one of its driest summers on record.

After this rainfall event, the rainfall total for the summer of 2012 (Jun-Aug) stands at 14.81 inches which now ranks

as the 4th wettest summer on record. Below is a list of storm total rainfall reports along with an image of the total

rainfall from August 9th through the morning of August 11th based off radar estimates.
