Today's Tornado and Severe Thunderstorm Threat

Storms have already developed and it is going to the a busy day.

Keeping in mind that 5% is the significant threshold, there is a large area where tornadoes are possible today. The hatching in the 10% area is where the Storm Prediction Center is forecasting violent tornadoes.

For thunderstorm-related winds of 58 mph or higher, 15% is the significant threshold. Probabilities are very high.

For 1" or larger hail, the significant threshold is 15%. The hatched area is where 2" or larger hail is forecast.

Thunderstorms have already developed in the region. AccuWeather is reporting more than 4,000 homes and businesses are without power in West Virginia. Here is the AccuWeather Regional Radar at 9:35am EDT:
While only JFK Airport has delays due to the storms at the moment, delays will rapidly increase with the thunderstorms. If you can get an earlier flight, it would be recommended.

If if you live in the area where tornadoes and damaging thunderstorm winds are forecast:
  • Bring in trampolines, grills and outdoor furniture
  • Put your car in the garage
  • Get some extra cash at the ATM
  • Pay attention to the wether today.
