quality being diminished likely when it gets this hot. theylso justssued that air quality alert, air quality alert meaning ' you young or old you want to take it easy but the heat out there is excuse enough to take it easy and then over the weend we have an excessive heat watch in effect. talking about a lot of advisories and warngs, what's the difference? here's the difference. a watch means that something could happen. so that excessive heat watch over the weekend means we could be dealing with dangerous heat and an advisory means it's happening and the risk level is aoderate situation. in our area a heat advisory does constitute dangerous heat for us here, what we're accustomed to dealing with. a excessive heat warning means it's a high-risk situation. everybody really needs to heed caution to the weather alert, and an emergency would be soething like what we saw a week ago with that flood emergency issued on monday. here's how hot it's feelingow tomot 8:00 a. i can't believe these numbers. mo's already feeling close to 90

for of us at 8:00 a.m. lunchtime it's feeling anywhere rom 100 to 105 degrees out here.t 110 degrees for the feels-like temperature, and that's why i think we could see the upgrade to an a excessive heat warning out there. even tomorrow night at 7:00 p.m., you're thinking the sun is starting to go down, a little bit of relief and maybe the kids can get outside and play. case.e still in that heat advisory criteria until about can the p.m., and we have that excessive at wdayat br utchvee oweth over. our temperatures remain , stiflingo if you don't have air conditioning, you don't get relief out there. something to be taken very . seriously up in one fatalities related to weather in the united states are actually heat-related, and here'the heat index over the weekend. tomorrow feeling about 110. this is worst case scenario, 1s n friday. saturdaye fing about 1 is15

degrees and sunday 113 with then heat humidity. that mean you need to think about pets because the a phalt temperature is much greater than the air temperature. if you can put the top of your hands wa the si, if you can't keep it there for seven seconds, it's too hot for your dog. 100 on saturday and 99 on sunday and maybe some thunderstorms later sunday. on monday thunderstorms are likely. i'm going tore have mo on how hot it the feels over the weend, and when reliefek a
