Why Middle Tennessee isn't under a freeze warning Wednesday morning
NASHVILLE, Tenn. (WKRN) — Temperatures are forecasted to drop near and below freezing across all of Middle Tennessee and Southern Kentucky on Wednesday morning. Freeze warnings or frost advisories have been issued in Southern Kentucky, West Tennessee, and North Alabama, but not in Middle Tennessee. News 2 spoke to the National Weather Service in Nashville to learn why.
According to Caleb Cravens, a meteorologist at the National Weather Service in Nashville, frost advisories and freeze warnings will only be issued during the growing season. He said they use past weather data and spoke with local farmers to determine the growing season to be from May 1st until September 30th.

'In this area we standardize our frost advisories and our freeze warnings and we only issue them when it's outside of climatological normal to see freezing temperatures, and so in Middle Tennessee on average our last freeze is going to be between April 10th and the 15th, and because of that, because it's not unnormal to see freezing temperatures until April 10th or 15th we will not issue a frost advisory or freeze warning before that date,' Cravens told News 2.
Along with Nashville, the National Weather Service office in Morristown, Tennessee, also follows these dates, while other surrounding offices follow different criteria.
The offices that change their criteria year to year are in communication with local farmers to determine when to start issuing frost advisories and freeze warnings. National Weather Service Huntsville meteorologist Dan Dixon said, 'The growing season is primarily based on the status of growing vegetation in our region.'

All the different criteria can be confusing. So the easiest way to know if you are going to get a frost is to watch the News 2 Weather Authority team's forecasts!

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A severe tornado warning was issued early Friday morning by the National Weather Service in Tulsa, Oklahoma, urging residents in Osage and Pawnee counties to take cover immediately. At 3:09 a.m. CDT, radar detected a severe thunderstorm with rotation, located approximately nine miles east of Marland, and moving east at 35 miles per hour. The storm was reported capable of producing a tornado and half-dollar-sized hail, prompting officials to warn that flying debris could pose significant danger to anyone caught outside without shelter. Interactive maps from showed the paths of the storms. What To Know Early Morning Tornado Threat in Northern Oklahoma The National Weather Service (NWS) in Tulsa issued a tornado warning effective from 3:10 a.m. CDT to 3:45 a.m. CDT on June 6, 2025, for Osage and Pawnee counties. Officials reported radar-indicated rotation within a severe thunderstorm east of Marland, with hazards including the potential for tornado formation and hail up to half-dollar size. The NWS advised that "flying debris will be dangerous to those caught without shelter," and noted wind damage to mobile homes, vehicles, roofs, and windows was likely. Communities at Risk and Safety Instructions Ralston and Fairfax were identified as being within or near the storm's projected path during the warning period. Residents in affected areas received instructions to immediately move to basements or interior rooms on the lowest floor of sturdy buildings, and to avoid windows. Those in vehicles, mobile homes, or outdoors were urged to seek substantial shelter and protect themselves from flying debris. The NWS emphasized that timely compliance with these safety instructions can be lifesaving during rapidly developing tornado threats. Wider Severe Weather Outlook for the Central U.S. The tornado warning was part of a broader severe weather pattern across the central and southern High Plains. Forecasters anticipated scattered severe thunderstorms throughout the day, with associated risks including very large hail, damaging winds, and additional tornadoes. Tornado History in the Region Oklahoma regularly experiences severe weather, as evidenced by a tornado in Norman on June 3, 2025. During that storm, the National Weather Service confirmed a tornado, though officials reported "hardly any damage" in the Oklahoma City metro area. Nonetheless, the region saw significant rainfall, hail, heavy winds, and flooding. Preparedness and Monitoring The National Weather Service urged continued vigilance as the storm track shifted eastward. Emergency officials stressed the importance of monitoring weather updates and local alerts. Real-time impacts and damage reports were made available through NWS networks nationwide, helping residents stay informed and safe during ongoing severe weather activity. Why It Matters The latest severe weather outbreak highlights the persistent tornado risk across the central United States, particularly in Oklahoma, which sits within what is often referred to as "Tornado Alley." Extreme weather events like these endanger lives, disrupt communities, and test emergency preparedness systems. Understanding and responding to warnings from the National Weather Service remains critical for public safety, especially as spring and early summer bring a heightened risk of violent storms to the region. What Happens Next The National Weather Service continued to monitor conditions in Osage, Pawnee, and surrounding counties for further tornado development, issuing updates as the situation evolved. Residents were advised to heed official warnings throughout the severe weather cycle and stay alert for any additional storm advisories or emergency instructions.

Tornado warnings give Lubbock first true test of new outdoor warning system
Lubbock's relatively new Outdoor Warning System got its first true test in a non-simulated situation Thursday when a line of tornado-warned storms moved through the county. The sirens came through loud and clear, adding a layer of alerts to the smart phone notifications, local media and other warnings residents received after the National Weather Service in Lubbock issued multiple tornado warnings Thursday evening. More: Check here for live updates as storms bring tornado damage in West Texas, watch remains While the storm system produced several confirmed tornadoes west of the city - including in Hockley and Cochran counties - and NWS Lubbock forecasters saw enough indicators to issue warnings for Lubbock County and the city, there were no confirmed reports of tornadoes touching down in Lubbock during Thursday's weather event, according to the city of Lubbock. The outdoor warning system, with 45 sirens, came online in 2022 and has periodically been tested by the city - typically on Friday mornings once a month. The City of Lubbock initially budgeted around $1 million for the project and approved a contract with the Oklahoma-based Goddard Enterprises in February 2021 for $710,415, the Avalanche-Journal reported at the time. The city of Lubbock released a statement late Thursday after the severe weather system moved through the area. "At approximately 6:55 p.m., the National Weather Service included Lubbock, Texas in a Tornado Warning. This warning activated the Outdoor Warning System (OWS). This Tornado Warning also activated the Integrated Public Alert Warning System (IPAWS). These emergency warnings provided our citizens the best opportunity to get indoors & seek shelter immediately before the storm entered the City of Lubbock, Texas. Currently, the City of Lubbock does not have any confirmation of a tornado touching down within the city limits of Lubbock, Texas. Additionally, the City of Lubbock has zero reported injuries related to the storm. The storm that did come through the City of Lubbock posed a great amount of structural damage, debris in roadways, and severe roadway flooding. Several residents within the city limits are experiencing power outages. Lubbock Power & Light and South Plains Electric Cooperative are actively working to restore power and will continue to work throughout the night. Lubbock Power & Light is reporting approximately 1,400 customers without power. Lubbock Fire Rescue, Lubbock Police Department, the City of Lubbock Office of Emergency Management will continue to monitor damages and conditions."
