National Weather Person's Day!

Today is National Weather Person's Day! Today the Weather on the Ones Team thanks our partners at the National Weather Service Offices in the Carolinas who have a great working relationship with the media!

Here's more information on the day from a press release issued by the National Weather Service Office in Raleigh --

Thursday, February 5 is National Weatherman's Day, commemorating the birth of John Jeffries in 1744. Jeffries, one of America's first weather observers, began taking daily weather observations in Boston in 1774 and he took the first balloon observation in 1784. This is a day to recognize the men and women who collectively provide Americans with the best weather, water, and climate forecasts and warning services of any nation.

Many of us take weather information for granted. Turn on a light switch, you get light. Turn on your television or radio, or check a web site and you get the weather forecast. It’s easy to forget that around the clock, dedicated meteorologists and weathercasters are vigilantly creating forecasts to help you plan your day, and issuing warnings to help keep you safe.

The men and women at your local National Weather Service (NWS) forecast office gather the raw weather data, analyze the data, and study numerical computer models in order to issue the weather and river forecasts and warnings to protect life and property. Specialized marine and aviation forecasts help enhance the Nation’s economy. Spot forecasts help firefighters control wildfires and emergency management officials contain hazardous chemical spills. Extensive climate records help engineers, architects, researchers, insurance companies and utilities.

The primary mission of the NWS is to provide the American public with the best possible warning service to save lives. Recent severe weather statistics show that we continue to improve our capability to warn the public of impending hazardous weather. Nationally, lead time for flash flood warnings improved from 22 minutes in 1993 to 78 minutes in 2008. Accuracy over the same time period increased from 71 percent to 91 percent. Lead time for tornado warnings has increased from 6 minutes in 1993 to nearly 15 minutes today. Tornado warning accuracy increased from 43 percent to 75 percent. Winter storm accuracy in 2008 was 89 percent with an average lead time of 17 hours. Since 1990, the Tropical Prediction Center’s 24 to 72 hour tropical storm forecast track errors have been reduced by more than 50%. These more accurate and longer lead time warnings help communities stay safe.

Locally, the Raleigh NWS forecast office, which serves 31 counties in central North Carolina, had an accuracy of 83 percent for tornado warnings in 2008 with an average lead time of 15 minutes. For the stronger and more dangerous EF2 and greater tornadoes, the numbers improve to 100 percent detection with 20 minutes of lead time. Flash flood warning accuracy was 90 percent with an average lead time of 60 minutes. For the recent winter storm, the first to impact the area in five years, accuracy was 100 percent with an average Winter Storm Watch lead time of 29 hours.

But the NWS couldn't accomplish its mission without a diverse group of partners helping in the process.

Nationwide, more than 11,000 volunteer Cooperative Observers take regular measurements of temperature, precipitation and other data, which is used by forecasters and climatologists. Nearly 300,000 volunteer storm spotters are trained by the NWS to provide visual reports of severe weather conditions to forecast offices and local emergency management officials. Volunteer amateur radio operators provide critical emergency communications during severe weather.

The Raleigh NWS office has a network of 80 dedicated volunteer Cooperative Observers throughout central North Carolina. Nearly 500 volunteer observers report through the new Community Collaborative Rain, Hail, and Snow (CoCoRaHS) network. Thousands of people attend SKYWARN severe storm spotter training classes in the local area each year.

Most of the colorful weather graphics seen on television and in newspapers come from another member of the America's weather team. Commercial weather companies enhance the presentation of the NWS data and information for their clients in the media and in many weather-sensitive industries, and provide customized forecasts and services for clients.
And finally, television weathercasters are the most visible members of the America's weather team. They are the trusted faces many people turn to for weather information, and they relay the NWS’s official watches and warnings for hazardous weather.

On National Weatherman's Day, the NWS would like to thank all of the volunteers and our partners in television and commercial weather services. Thank you!
