Showers and heavy thunderstorms will bring the risk of flash and urban flooding to portions of Kansas, Missouri, Oklahoma and Arkansas Monday into Tuesday.
The storms have the potential to drop from 1 to 3 inches of rain in as many hours with a half a foot of rain a possibility during the event in a few locations.
Cities in the risk area for blinding downpours, travel delays and flash flooding include Wichita, Kan., Tulsa and Oklahoma City, Okla., Springfield and St. Louis, Mo., and Fort Smith, Ark.
The storms will form and move slowly eastward along the boundary between cool air to the north and hot, humid air to the south.
A few of the storms along the southern edge can also bring severe weather with damaging wind gusts, hail and frequent lightning strikes.
Heavy rain has fallen on parts of Oklahoma and southern Kansas during the last couple of weeks of July. Since July 1, Oklahoma City has received over three times their normal rainfall with 8.62 inches. Wichita has received two and a half times their normal rainfall with 7.67 inches, since the start of the month.
As a result, much of the rain in this area will run off, rather than be soaked up by the ground, which will elevate the flooding potential.
The central Plains will remain in a region where additional rounds of showers and thunderstorms will occur through the balance of the week, so it is possible the region will continue to experience problems related to heavy rain and flooding.
A "blob" of abnormally cold water in the North Atlantic, located near Greenland, has the potential to put enough drag on the ocean current to impact weather conditions in the years to come.

Residents from McPherson, Kansas, to Norman, Oklahoma, told the USGS that they felt the earthquake, according to the USGS website.
After a period of above-average temperatures across the Northeast for much of this week, a return to more fall-like conditions will be in store this weekend.
A strengthening storm system will bring the threat for flooding, mudslides and severe thunderstorms to areas from Italy into the Balkans later Friday into the weekend.
“It was by far the most intimidating natural disaster I have ever chased,” Storm Chaser and Extreme Meteorologist Reed Timmer said of the historic flooding in South Carolina.
