4/6/2023 0 Comments Weather across the us![]() ![]() Summertime thunderstorms, even when not severe, can turn deadly in a flash as people spend more time outdoors, where they are vulnerable to lightning strikes.Ī 2020 report from the National Lightning Safety Council analyzed lightning-related fatalities across the country from 2006 through 2019 and found July to be the deadliest month for lightning strikes, followed by June and August. Severe weather tends to decrease some in June, July and August, but thunderstorm activity generally becomes more widespread across the country. As a result, it will be difficult for a high frequency of thunderstorms to develop in this area and especially challenging for a tornado to reach the ground.Īny thunderstorms that do develop over these drought-stricken areas will bring beneficial rainfall for farmers, but large hail and strong winds could also lead to crop damage. Too much dry air and heat will put a cap on the severe potential across this region as the parched earth deprives the atmosphere of moisture. The worst drought in the entire country is currently ongoing in this zone, especially across western Kansas, according to the U.S. "Drought conditions will be across the central and southern Plains, especially the High Plains," Pastelok said. This is outside the area traditionally considered Tornado Alley, which extends from central Texas through South Dakota. The focal point of the worst severe weather outbreaks is likely to follow the trend of recent years when the worst of the storms unfolded over the eastern Plains into the Gulf Coast and Tennessee Valley.

However, there is a chance that the frequency of these events may be lower this year and could track farther south than in previous years.ĪccuWeather predicts 1,055 to 1,200 twisters will touch down across the United States throughout 2023, slightly below the historical average of 1,225.Įven with a fast and furious start to March, tornado activity for the month as a whole could finish near historical averages and significantly lower than what was observed in March 2022. ![]() When conditions are right, they can evolve into derechoes. These clusters of severe storms are common during the second half of spring and throughout the summer and are notorious for strong winds. Pastelok explained that long-lived complexes of thunderstorms could track across the northern Plains and into the Midwest in May. The resurgence of severe weather will include a new risk. The frequency of tornadoes and severe thunderstorms will rebound late in April and into May, as well as expand into the Southeast, Midwest and northern Plains. ![]()
