oklahoma ended years long drought. but caused deadly flooding and millions of dollars in damage. more tornadoes were reported last month than any time since april 2011. i heard you say earlier we have a slight chance of tornadic activity in our area? devon: a marginal risk. just incredible. going back to the story, there was extreme drought but a step further, which is called exceptional drought. it is the most extreme. they got rid of it in just a couple of weeks. but you are exactly correct. a risk of severe storms even a marginal risk. we were tracking storms that were west about the 6:00 hour. we thought that could spark some storms nighttime. we did. rocked a storm through frederick. trying to develop brain northwest of the sea south fairfax -- northwest of d.c. south fairfax, this william county, lawton county and into marshall. that is the storm activity rolling southeast. that means these storms got to folks southeast. that is not the normal track some of these storms take. real-time air temp feels closer to 90 when you factor in the humidity. the big picture of the next two days, mostly about humidity. storms tracking well away from the region and that is what it is that's what is making it extreme difficult. when you're closer to the storms, you know it will fire up to the farther way you get, it is a guessing game between whether those storms are like what we are doing overnight hours. warm and humid to start. storms fire up midmorning sunday. that would limit high temperatures. nor -- more cloud cover and more rain. however, if we push storms to the afternoon time period, maximum heating, more sunshine and a severe threat to come in. lower 90's would do it. if we had more cloud cover and 80's, that would hold that severe chance down. a slim chance on top of that, an isolated tornado. for the bay bridge slim, hot for air temps. water temps not bad. widely isolated storms coming in monday. still really hot and humid. lower to mid 90's, could feel like upper 90's and closer to 100. we've got that slight risk of severe storms that we are tracking closely. the seven-day forecast, really -- it looks like we got a mistake in the rundown. sunday forecast, chances of storms. lower 90's coming in with humidity. we could break that humidity with a strong cold front. but we will hold with the hot weather until we know more. kellye: sweet
