SNOW SQUALLS: Dangerous winter driving conditions

Published: Friday, December 09, 2016 @ 4:29 PM

Be prepared this winter to know what to do if you find yourself driving in a Snow Squall this Winter.

We see snow squalls in the Miami Valley nearly every winter season, even though they are most common in lake effect snow areas. 

WHAT IS A SNOW SQUALL?

StormCenter7 Meteorologist Kirstie Zontini describes a snow squall as a burst of snow that quickly drops visibility levels to zero. They are usually accompanied by gusty winds which only make visibility worse as snow blows and falls simultaneously. 

WHY ARE SNOW SQUALLS DANGEROUS? 

Snow squalls are very localized. Driving conditions and roadways can look clear and safe one minute, and a minute later, you can't see. Drivers are caught in the whiteout as they are traveling at fair weather speeds which can result in chain reaction rear-end crashes like the incidents below.

Humidity brings increased threat for showers, storms this weekend

Published: Friday, July 21, 2017 @ 7:16 PM

Weekend Weather Threats for the Miami Valley

The high heat and humidity will stick around for the weekend, along with the threat for thunderstorms.

While storms may cool us down from time to time, our team of Storm Center 7 meteorologist say not to expect much relief from the steamy conditions until late Sunday or Monday.

A cold front will slowly push into the region over the weekend, which will lead to an increased threat for showers and storms.

5 Day Forecast with Chief Meteorologist Eric Elwell

"The added heat and humidity will only help fuel the storms," Storm Center 7 Chief Meteorologist Eric Elwell said. "This could create storms capable of not only producing flash flooding, but also a threat for damaging wind gusts."  

Two rounds of storms will be possible, Elwell said, with one expected early Saturday morning and another round either Saturday evening or even late at night. Both rounds of storms could create problems with heavy rain and strong winds. The storms are expected to slowly move out of the region on Sunday with humidity levels finally dropping. The relief from the heat should last into early next week.

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 

WHIO weather app

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.
