Following another day of locally heavy rain across parts of the Plains and Midwest, flooding remains a threat for many areas. The risk extends beyond flash and urban flooding.
Since Wednesday, rainfall amounts of 1-2 inches have been common from central Nebraska, Kansas and Oklahoma into Iowa, Wisconsin, western Illinois, Missouri and Arkansas.
Some of the heaviest rainfall on Thursday was seen in Coffeyville, Kan., where 4.07 inches was record.
Elsewhere, 3.36 inches fell in Little Rock, Ark., and 1.88 inches in Wichita, Kan., both of which broke daily rainfall records for the date.
The slow movement of this storm system means that areas from eastern Oklahoma into Michigan and the Ohio Valley will be at risk for flooding through Saturday.
Some cities at risk during this time include Tulsa, Okla., St. Louis, Chicago, Indianapolis and Detroit.
The combination of rain and thunderstorms will result in new rainfall amounts of 2-4 inches from eastern Oklahoma into Arkansas and Missouri as well as across much of the Ohio Valley and southern Michigan.
This amount of rainfall on top of areas already soaked by recent rains have prompted flood watches and warnings from eastern Oklahoma into northern Arkansas and northward into Illinois as of Friday morning. These areas are where the heaviest rainfall is expected through Friday night.
On Saturday, the threat for heaviest rainfall will shift eastward into southern Michigan, western Ohio, Indiana, southern Illinois, southeastern Missouri and Arkansas. These areas can expect strong thunderstorms with heavy rainfall leading to flooding of area streams and rises on rivers.
The storms on Saturday will be capable of producing damaging winds, large hail and isolated tornadoes, adding to the problems expected across the region from the flooding rainfall.
This storm system will finally head farther east Sunday into Monday; however, no widespread flooding problems are expected across Northeast or mid-Atlantic.
Gusty thunderstorms will target the northeastern United States on Monday, but will fail to sweep away the heat wave baking the region.
Dangerous heat will surge northward and send temperatures rising across the northwestern United States this week.
Downpours will spread from the lower Mississippi Valley to eastern and central Texas early this week, delivering needed rain but raising the concern for flash flooding.
A renewed risk of severe weather will threaten portions of the north-central United States early this week.
With the heat of summer comes many unwelcomed pests, including mosquitoes, ants, fruit flies, wasps and stink bugs, into outdoor spaces and homes.
