Heavy Rains & Thunderstorms

The last several days and potentially the next several have been filled with rounds of thunderstorms. Creating flooding concerns and the potential for severe weather during every event, luckily so far there hasn't been any truly dangerous situations. This morning we have thunderstorms developing in northwestern Iowa as well as moving into the area from SD/NE. These thunderstorms will likely work across the northern portions of the state throughout the morning hours, with some clearing taking place behind them. This clearing will potentially set the stage for more severe weather this evening over areas of northwestern Iowa and adjacent areas of NE/SD/MN. The western half of the state is in a 'slight' risk for severe weather this afternoon/evening; with the potential for large hail, damaging winds and an isolated tornado. The best tornado chances are currently forecasted to occur 50 miles east/west of a Omaha to Sioux Falls line. With any thunderstorms that train over the state, it is likely that flash flood warnings or flood warnings may be issued. Several counties in northwest Iowa and even central Iowa are currently under flood or flash flood warnings this morning. Additional updates on today's severe risk may be posted later...

Highs for Monday ranging from 80 degrees in the northeast to the lower 90s possible in the southwest. Lows tonight from the mid 60s in the north to the lower 70s in the south. As mentioned, thunderstorms chances exist for a majority of the state both today and overnight.
