Where is this nor Easter coming from?
The low pressure system causes clouds to form and a storm to develop. A nor’easter forms when cold air often originating in Canada blows over the warm Atlantic Ocean off the coast of the eastern United States.
What caused the 2021 winter storm?
A combination of a large trough in place over the Central United States, a large polar airmass being channeled southward, and moisture from the Gulf of Mexico caused snow and freezing rain to fall over the Southern States.
What states are affected by nor Easter?
A nor’easter is a storm or wind blowing from the North American northeast. The storm develops between Georgia and New Jersey, but hits the New England area with maximum intensity, according to the NOAA.
How cold did it get in Texas in 2021?
As can be seen, large swaths of southeast Oklahoma and eastern Texas dropped below -10°F to -20°F during the February 2021 event.
Why is Texas getting snow?
Climate change makes storms worse and more unpredictable. Global warming and higher temperatures lead to increased evaporation. Eventually, this increased evaporation leads to increased precipitation. At certain times, when temperatures are cold enough, this precipitation is snowfall.
What air mass produces nor Easter?
polar cold air mass
Nor’easters bring very cold air down from the Arctic. Nor’easters thrive on the converging air masses; that is, the polar cold air mass and the warmer ocean water of the Gulf Stream. Nor’easters will usually develop between 30° N.
How is lake effect snow formed?
Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. The air rises, clouds form and grow into narrow band that produces 2 to 3 inches of snow per hour or more. Wind direction is a key component in determining which areas will receive lake effect snow.
