Severe Thunderstorms and Flash Flooding threaten mid-west

A moving cold front from the North-West is going to clash with the warm air from the Gulf of Mexico and the jet stream should create severe weather across the Mid-West. There is a chance of an isolated tornado or two. These storms will bring strong winds and some hail. Due to the amount of rain from these storms there is a possibility of flash flooding occurring.

"In addition to the severe threat, flash flooding is also a concern over the next couple of days because any storms that form will have plenty of moisture to work with, due to a southerly wind flow off the Gulf of Mexico, so excessive rain amounts are possible within a short period of time...A broad swath of 1- to 3-inch rain amounts is expected across parts of the northern Plains and Upper Midwest through Wednesday, with isolated areas seeing upwards of 3 to 5 inches. Keep in mind, a lot of this rain may fall in a short period of time, hence the risk of flash flooding."

"The heaviest rain looks to set up over parts of Iowa, Minnesota and Wisconsin."
