Severe Threat Targets South, East Mid-Week
Another round of unseasonably warm temperatures will lead to another threat for severe weather across parts of the South and Midwest on Tuesday and Wednesday.
An enhanced risk for severe weather is in place across parts of the Ozarks and the mid-Mississippi River valley for Tuesday as more warm temperatures and high dewpoints fuel possible thunderstorm development. All modes of severe weather, including tornadoes, large hail and strong winds, are possible on Tuesday, particularly in the orange-shaded enhanced risk zone.
By Wednesday, the threat expands and shifts further east, covering much of the eastern time zone. At this point, the primary hazard appears to be a straight-line wind damage threat, although tornadoes and large hail could also develop on Wednesday in these areas as well, particularly in the 30 percent zone.
This week’s severe weather possibility comes on the heels of a highly unusual severe weather outbreak on Saturday across the East Coast, including a confirmed EF-2 tornado in Pennsylvania, only the second recorded tornado in Pennsylvania history, and the first since 1990.
It’s part of an above-average trend for severe weather, and specifically tornadoes, so far in 2017 across the country. So far, 180-190 preliminary tornadoes have touched down nationwide, approximately three times above the year-to-date average. Warm Gulf of Mexico sea-surface temperatures and an overall warm pattern across the eastern and southern portions of the country have helped contribute to the strong early bout of severe weather.
