torrential downpours all the way from houston to new orleans and across parts of the florida gulf coast. really much of florida will be looking at some substantial rain as we go through the first part of this week. things are changing. heat-wise. we had low humidity here in the northeast over the weekend. things are changing because of this big high pressure dome. it's going to bring really, really high temperatures in the triple digits across the plains and eventually all this heat will be moving to the east. places like washington, new york, philadelphia, will be feeling heat and humidity even by tomorrow. >> a lot to watch out for, especially those areas affected by wildfire. bonnie schneider, thank you for that. after capturing the city of mosul from isis control. >> up next, live to london after the bloody battle for the country's second largest city. keep it here, everybody. across the country, we walk. carrying flowers that signify why we want to end alzheimer's disease.
