Lake-effect Snow and Whiteout Conditions in the Great Lakes Region; Below-average Temperatures in the East

A coastal low will produce moderate to heavy snow over parts of southern and eastern New England into the afternoon. Below average temperatures are expected across the eastern U.S., particularly with chilly morning temperatures. Read More >

Overview

Tropical Depression Cristobal tacked across much of the mid and upper Mississippi River Valley on the morning and afternoon of June 9, 2020. Very high levels of moisture were brought in tow, bringing very heavy rainfall to much of the region, especially eastern Iowa. By the time it was said and done, rainfall amounts of 2 - 4 inches fell roughly west of a line from Keosauqua IA, to Burlington IA, to Guttenberg IA. Localized amounts of 4 - 5 inches were reported near Belle Plaine, IA.

This torrential rainfall led to numerous reports of flooded roadways, road closures and creeks out of the their banks. In addition, area rivers also showed response, with some rising near to well above flood stage.
