What you may not know is that these are both produced from the same event. Severe thunderstorms are likely to produce damaging winds and large hailstones in the warning area over the next several hours," the warning said. Most likely time for hail, heavy rain, frequent lightning, strong winds, and tornadoes. Expert Answer 100% (1 rating) Previous question Next question Get more help from Chegg. What type of weather will this region most likely experience due to the incoming air mass? Relatively weak … Thunderstorms form from cumulonimbus clouds, but they don't have to be low.

"Locations which may be affected include Orange, Mudgee, Bathurst, Dubbo, Parkes, Wagga Wagga, Albury, West Wyalong and Tumbarumba." Scientists don't know how a mesocyclone transforms into a tornado, but maybe a downdraft pushes the mesocyclone down until it reaches the ground. Conditions for either storm are very good at this stage. These storms are likely to produce large to very large hail and locally damaging wind gusts. And, the collision between the ice particles is what scientists think generates the static electricity that forms lightning. Learn vocabulary, terms, and more with flashcards, games, and other study tools. First there needs to be some atmospheric instability, so a layer of warmer air above a layer of colder air. The greater the difference, the strongest the weather. The Bureau of Meteorology has issued a severe thunderstorm warning for part of the Northern Rivers Forecast District, warning of showers of storms likely to produce heavy rainfall which could lead to flash flooding.

Severe thunderstorms are defined as having sustained winds above 93 kilometers (58 miles) per hour or unusually large hail, and there are two key factors that fuel their formation: convective available potential energy (CAPE) and strong wind shear. a. When the unstable air collides, it starts rolling on its side like a barrel. Polar regions, including Antarctica, are too cold to have moisture sufficient for the condensation and deposition required to support thunderstorms, even in the summer. Jane filled one glass with warm water and one with ice water. The warm, moist air stays near the ground. Lifting Mechanism, Fronts, Moisture . Start studying Chapter 7 test practice.

SEVERE THUNDERSTORM WARNING – A severe thunderstorm (damaging winds of 58 miles per hour or more, or hail three-fourths of an inch in diameter or greater) is taking place in your area. An air mass is unstable when cool dry air is near the surface and warm moist air is aloft. The strongest cells may also produce a tornado or two.
