Multiple cold fronts progressed across the central and eastern U.S. during mid to late June with widespread showers and thundershowers from the Great Plains east to the East Coast. During the past week (June 18 to 24), heavy rainfall (2 to 6 inches) maintained excessively wet conditions across eastern portions of the Great Plains, middle Mississippi Valley, and Ohio Valley. Diurnal convection resulted in locally heavy rainfall (more than 2 inches) from the Florida Panhandle south to the central Florida Peninsula. An unseasonably strong low pressure system resulted in accumulating snow to the northern and central Rockies on the first full day of the summer. More than a foot of snow was observed at elevations above 9,000 feet in the Colorado Rockies. During mid to late June, cooler-than-normal temperatures persisted throughout the western and central Corn Belt. Above average rainfall has occurred throughout a majority of the central and eastern U.S. during the past 30 days, with below average rainfall limited to scattered areas of the Southeast, south Texas, the northern Great Plains, upper Mississippi Valley, and Pacific Northwest.
