ROB MARCIANO, AMS METEOROLOGIST: You're looking at a picture of a tornado that touched down in south central Minnesota over the weekend; look at that thing. Hayfield, Minnesota, about an hour or so south of Minneapolis, this was rated an EF-1. A little bit of damage but no injuries to report, certainly a dramatic video though, as that tornado touched down late in the day on Friday. Good morning again, everybody, I'm Rob Marciano, in the CNN's Severe Weather Center. We do have the threat of severe weather as the northern part of that front makes its way east. It is bringing some relief to the central plains but some rough weather this morning rolling across the I-90 in upstate New York. This severe thunderstorm watch in effect for 1:00 this afternoon; they may drop it sooner than that but some of this individual cells are rolling eastward about 35, 40 miles an hour and they could have some gusty and damaging winds. All right, some rotation, a little bit of a circulation here, this is what's left over of tropical depression number 5, which kind of did a loopy-loop and is now kind of meandering here in the Gulf of Mexico. The National Hurricane Center is watching that for potentially getting back to tropical depression status; airplane flying in there later today. A hundred to 105 degree heat indices here in eastern Texas and parts of the Deep South. Notice that most of the real hot air has been pushed south where it belongs but also across parts of the Pacific Northwest, where heat advisories and excessive heat warnings are in effect for Seattle, where they set a record yesterday of 96 degrees, it was 97 degrees in Olympia. They don't have the oppressive humidity, but folks who live in this part of the world, not everybody has air conditioning. So it is enough to take the body by surprise, for sure. One hundred today in Dallas, it will be 87 degrees in St. Louis, 88 degrees with afternoon thunderstorms in New York City. But 89 in Kansas City and 79 in Minneapolis, that is definitely cooler than it was around this time last week. That's a quick check on weather. AMERICAN MORNING is coming right back.
