[ARCHIVED] Severe weather possible Wednesday afternoon, evening


A possibility of isolated severe storms exists for Allen late this afternoon into this evening. The primary threat will be large hail and tornadoes.

Midday storms are possible around lunchtime but are not expected to be severe. A better chance of severe storms will develop this evening, estimated around 7 p.m. Though the threat of severe weather is low, residents are urged to monitor the weather and have a method to receive weather alerts this afternoon into this evening.

Receiving alerts

The best source of weather alerts is a NOAA all-hazards weather radio which activates when it receives a radio signal from the National Weather Service. These radios can be kept in your vehicle, in your home or carried while camping/attending an outdoor event to alert you to severe weather in your area.

Backup options include:

Outdoor sirens

To provide additional warning to people who are outdoors, Allen operates 23 outdoor warning sirens that sound during severe weather events. You may not hear them inside as air conditioning, thunder, wind, rain and other conditions can drown out the sound. Sirens are activated for:

  • Hail greater than 1 inch in size
  • Winds greater than 70 mph
  • Tornado warnings from the National Weather Service naming Allen in the path
