— The Leonid Meteor Shower will peak this weekend.
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.

Partly sunny, mild and muggy through the morning. Scattered thunderstorms develop into afternoon. Severe storms not expected but brief, heavy rainfall, gusty winds and lightning possible. Highs will climb into the lower to middle 80s. Storms will taper off this evening and become partly cloudy overnight. Lows in the upper 60s - Storm Center 7 Meteorologist McCall Vrydaghs said.
Sunday: Partly sunny, hot and humid. Slight chance for a pop-up shower or storm. Highs in the upper 80s, but feeling like the lower 90s.
Monday / Memorial Day: Lots of sunshine, hot and humid again. Highs will top out near 90 degrees with a heat index from 90 to 95 degrees.
Tuesday: Expect partly cloudy skies with muggy conditions and a high near 90 degrees.
Wednesday: Skies will become mostly cloudy with scattered showers and storms developing. Highs will drop back into the middle 80s.

— 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.
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.
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.

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:
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.
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.
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.
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.
HOW DO I SEE THE LATEST LIST OF SCHOOL/ BUSINESS CLOSINGS AND DELAYS?
We've added the latest list of school and business closings and delays in the WHIO Weather App so you can check the list from wherever you're located. Simply open the app, along the bottom is a tool bar, 'Closings' is the third option from the left. This will take you directly to the most recently updated list. This new feature will better help you plan your day, allowing you to adjust as needed when your kids' school or your place of business issues a delay or closes due to road conditions or other reasons.
I MISSED A NEWSCAST, HOW CAN I GET MY FORECAST?
If you miss a TV newscast, you can still keep up with the latest video forecasts our meteorologists create throughout the day. These short weather video segments tell the weather story of the day, how it will impact you, and contain their scientific explanations for unique elements of the forecast you won't get in a written story or graphic. This is a great tool during severe weather days and when a big winter storm may impact the Miami Valley. These custom video forecasts created by the StormCenter7 team of Meteorologists can be found under the 'Video' tab.
WHAT CAN I SEE ON THE INTERACTIVE RADAR BESIDES RAIN AND SNOW?
The Interactive Radar is available year-round in the WHIO Weather App. Features on the app allow you to see lightning strikes along with satellite and radar. Under the 'Radar' tab you can click on the 'Layer' icon to overlay things like watches and warnings so you can see where storms and alerts are in relation to your location.
