JOHNSTON, Iowa --
The National Weather Service says another round of strong thunderstorms along the Iowa-Minnesota border late today into this evening raises the prospects for flash-flooding in an area that's already seen quite a bit of rain this week.
In Johnston, meteorologist Andrew Ansorge says the storm system's possible shift to the north may put heavier rain in southern Minnesota.
"We are watching northeast Iowa where we're seeing some trends toward some heavier rainfall tonight. We'll be assessing that through the rest of the afternoon through the evening."
Ansorge says a cold front coming into the state tomorrow brings with it a chance for severe weather across the state. He says that front will also bring cooler, windy weather starting Friday.
