August 24, 2016: Tornadoes in Indiana today; Half foot of rain in parts of northeast Iowa last night; Snow at Pikes Peak, Colorado today; Tropical storm or hurricane potential this weekend/next week for the southeast U.S. Cooler and less humid weather in the Northland through Friday

/Issued 5:06 PM CDT, Wednesday, August 24, 2016/

Potential weather setup for the week of August 28th -- One of the bigger weather stories next week could be a tropical system, maybe a hurricane that could affect portions of the southeast U.S.; If you live in or have travel plans to the red outlined area on the map make sure you're paying attention to the weather forecast during the next several days.

As for the Northland, it actually looks like a pretty mild weather pattern next week with the jet stream near or off to our north/west which will result in a west or southwest flow aloft.  A frontal boundary might trigger some showers and thunderstorms from time to time from the northern Plains to the western Great Lakes but timing on when these storms could hit and what areas could be affected is highly uncertain this far out.

This will get snow lovers excited - Snow at Pikes Peak, Colorado today.  Elevation is around 14,000 feet so it isn't too unusual to get snow in that area in late August but still cool to see in late summer.  Here's a webcam link showing the snow today
