While a large portion of the country struggles with a heat wave, the upper midwest will be dealing with the possibility of strong storms later today and tomorrow.  While tornadoes are possible, the main threat looks to be strong winds and hail.

With any luck, the storms won't do any damage and may provide a brief respite for the upper midwest from the oppressive heat.

The rest of the country is experiencing significant above-average heat:

Remember that extreme temperatures are the #1 weather killer, more than tornadoes, hurricanes and lightning combined. If you must be outside, look for shade and avoid unnecessary physical exertion during peak heat hours (noon-5PM). Infants and elderly are especially at risk during extreme heat, and should be monitored closely.  Finally, drinking lots of water (16-32oz per hour) is a must to avoid dehydration.
