>> What you should know before viewing a meteor shower

 The Leonid meteor shower is named on its radiant point, the constellation Leo the Lion, which will become more active before dawn Nov. 17 and 18.

The shower will peak heading into the start of the weekend. After midnight Thursday, Leo will rise in the night sky, bringing  an expected 10-15 meteors per hour.

The best time to see meteors is a few hours before dawn Friday. Unfortunately, our next storm system will likely get in the way of viewing meteors Saturday.

The moon sets the next couple of days early in the evening so that means the sky will stay dark overnight making the meteors easier to spot. Find an open spot without city lights to view this shower.

    Heat Index: What is it? Why does it matter?

    Published: Thursday, May 24, 2018 @ 6:35 AM

    Meteorologist Kirstie Zontini looks into what the heat index is and why it is important.

     In the winter we talk about wind chill and in the spring and summer, it is the heat index that is important, according to Storm Center 7 Meteorologist Kirstie Zontini.

    RELATED: What is UV Index and how to protect your skin

    Both are apparent or "feels like" temperatures. The heat index is a "feels like" temperature that looks at the actual air temperature and how much moisture is in the air, either with relative humidity or dew point. When it is hot, it can be uncomfortable. When it is hot and muggy, it is a different level for our bodies. 

    The amount of moisture in the air impacts how well our bodies can cool off. When you are hot, your body starts to sweat, that sweat is then evaporated from your body into the atmosphere. If the moisture content of the air is high, it is harder for that evaporation to take place, and harder then for your body to cool down. 

    LISTEN: Cloudy with a chance of Podcast: A podcast for weather fans 

    Here is the actual equation for calculating heat index: 

     

    HI = -42.379 + 2.04901523*T + 10.14333127*RH - .22475541*T*RH - .00683783*T*T - .05481717*RH*RH + .00122874*T*T*RH + .00085282*T*RH*RH - .00000199*T*T*RH*RH

     

    As the air temperature and relative humidity increase, the heat index will as well. If it is 88 degrees with a relative humidity of 55%, the heat index would be 93 degrees. If it was 100 degrees with a relative humidity of 55%, the heat index would reach 124 degrees. This makes being outside when it is hot and humid more dangerous. 

    • 80-90° - Use caution. Prolonged activity outside or exposure could be dangerous. 
    • 90-103°- Use extreme caution. Lengthy exposure can cause heat cramps, heat stroke or heat exhaustion
    • 103-124°- Danger! Heat cramps and heat exhaustion likely. Prolonged exposure can lead to heat stroke.

    Weather app
    Weather app

    The free WHIO Weather App will keep you alert and informed of changing weather conditions, no matter where you are, at home or traveling on the road.  You’ll be able to access a live radar anytime, anywhere. You’ll also receive weather watches and warnings no matter where you are.

    Install the WHIO Weather App free now from the Google Play or Apple store. Right at your fingertips, you'll have access to:

    • Live radar to track rain, lightning and storms
    • School closings 
    • Hour-by-hour forecasts 
    • Hyper-local forecasts for your county 
    • Forecasts wherever you travel in the U.S. 

    HOW DO I ADD MY CITY OR LOCATION IN THE APP?

    Once you have downloaded the app, it is time to setup the locations you would like to monitor. Remember, these can change whenever you'd like with a push of a button. 

    • Once in the WHIO Weather app, look for the 'plus sign' at the top left of your screen  
    • Click Current Location to save your first city 

    After that, you can save up to 10 locations by typing in the city and state. These locations can be anywhere you wish to receive weather updates. 

    SHOULD I "ENABLE" BACKGROUND TRACKING? 

    A new feature in the app is its ability to track storms even when the app isn't open and update you wherever you go...even out of state. If you travel into a location that is being impacted by weather, you will automatically be updated through the app. 

    • Once in the App, click the 'plus sign' at the top left of your screen 
    • Go to the Settings button at the bottom of your locations tab
    • Click Background Tracking, this will take you to your phone's settings
    • Make sure under the 'Location' option you chose 'always'

    DO I HAVE TO BE ALERTED TO EVERYTHING WEATHER RELATED? 

    The WHIO Weather App is unique because it allows you to choose which the weather alerts for which you want to receive notifications. All watches, warnings and advisories that the National Weather Service issues are available in our app. 

    • Make sure there is a check by the alerts you want to receive
    • You can turn off any notification you don't want by clicking the check mark 

    WHY DIDN'T THE WARNING GO OFF ON MY PHONE? 

    A special feature on the WHIO Weather App is the ability for the app to notify you ONLY when your GPS or saved locations are in the POLYGON for a warning. The National Weather Service draws polygons when it issues warnings and advisories. If your location isn't in the polygon, the alert will NOT go off. 

    WATCHES on the other hand are issued for entire counties, not polygons. If your location falls in a county where a watch is issued you WILL get an alert. 

    ISN'T THE 7-DAY JUST LIKE ANY OTHER WEATHER APP? 

    Unlike most apps that rely on a computer to just dump weather data on to their app, the StormCenter 7 Team updates the forecast on the WHIO Weather App each day, multiple times a day. With the WHIO Weather App you are getting a detailed forecast specifically created for the Miami Valley. It's not from a meteorologist many states away.
