Example The North American blizzard of 2005 was a three- day storm that affected large areas of the northern United States, dropping more than 3 feet (0.9 m) of snow in parts of southeastern Massachusetts, as well as much of the Boston metropolitan area. While this was by far the hardest hit region, it was also a significant snowstorm for the Philadelphia and New York City areas, which both suffered occasional blizzard conditions and inch (30-38 cm) snow accumulations.storm United StatesMassachusettsBoston snowstormPhiladelphiaNew York Cityblizzard

Winter Storm Ingredients for Formation –Warm moist air from the South –Cold polar (continental polar) air flowing from the North Must be cold enough to cause freezing –Stationary fronts or Warm fronts lead to winter storms. –Jet stream usually dips down allowing polar air to affect the warmer southern air (maritime tropical) –The amount of snow or ice produced depends on the length of time the cold air is held in place and the amount of warm moist air pumped into the cold air.

Precipitation Ice Storms: Sleet/Freezing Rain/Hail –Rain encounters cold temps at or near the surface –Results in accumulation of ¼ in or more of ice Rain = Nor’easter –Named after strong North East winds produced –Warm moist air from the Gulf clashes with cold polar air from Canada. –Accompanied by strong winds and heavy rains. –Moves very slowly increasing the amount of damage to an area.

Precipitation Blizzards / Lake Effect: Snow –Low temps, usually 20 degrees or below –Wind speeds at least 35 mph –Jet stream dips down allowing cold polar air to strike moist warm air.

Caution!!!! SAFETY Don’t Drive: Only a small amount of precipitation can be dangerous. The high winds cause heat loss so bundle up. Generators, alternative source of heat, and lots of blankets available. Stay in a warm protected building. Always have extra food, water, and batteries.
