Rockford tallying double the amount of rain of a typical June

After last night’s flooding rainfall, the rain total for the month has jumped into the top 5 for wettest Junes on record with a third of the month to go.

The official total for Rockford is up to 9.33" as of Tuesday evening. This is already double what a typical June gets (4.65"), and is well past last June, when 7.49" fell along with flash flooding toward the end of the month.

This is the wettest June in 25 years. In fact, 1993 is in the record books as the wettest June for Rockford, when 11.85" of rain fell. 

The amount of water that fell in Winnebago County Monday night was staggering. The 3-5" that fell within a few hours translates to 27 trillion gallons of water, or 3.6 trillion cubic feet. If 593,000 cubic feet of water is discharged from the Mississippi River every second, then 70 days’ worth of water from the Mississippi hit Rockford and Winnebago county Monday evening.

The forecast is expected to be drier for a few days, with another chance at scattered showers and storms by Friday. The weekend and early next week are also looking fairly dry, but low chances for rain linger before the end of the month. Only another 2.5" of rain is need to tie the wettest June on record, but hopefully that amount doesn’t come all at once like on Monday.
