Scattered damaging winds and a couple tornadoes are possible on Saturday from parts of Ohio into northern West Virginia/Maryland, central and western Pennsylvania, and western New York. The thunderstorm threat will move into the Northeast on Sunday. Prolonged heat will continue across the Southern Plains this weekend and into next week. Read More >
Arctic Outbreaks are very cold air masses that typically originate in the Siberian Region of Asia, cross over the north pole into Canada and push south and east into the lower United States. While such air masses occur annually, most do not reach the Gulf South due to steering currents that shunt the coldest air eastward. The strongest outbreaks do reach the Gulf States about every four to five years on average.
Impacts from these strong frigid air masses can be quite large, including unprotected pipes bursting, large fish kills in shallow estuaries, major agricultural losses to citrus trees, tropical foliage and seasonal strawberry crops, increased risk of structural fires due to faulty application of heating devices, and increased risk of carbon monoxide poisoning from inadequate ventilation of fuel-based heating devices. Economic impacts from Arctic Outbreaks along the Gulf Coast region can be comparable to a Category One hurricane impact. Below are a few of the more notable Arctic Outbreaks during local recorded weather history.
