Low pressure over the Southwest will bring rain and snow all the way from Arizona to the Dakotas and into the Southern Plains. Some heavy snowfall will be possible at higher elevations. High pressure over the Northern Rockies is going to bring another shot of Arctic Air southward with temps only in the teens over the Plains today.

Ask The Weatherman for November 21, 2013:
Question: What is cold air advection?
Answer: Today we look at cold air advection. This is when the transportation of cold air either horizontally or vertically is taking place. This type of advection takes place in the Northern Hemisphere. When northerly winds blow, they push the colder air from Canada and the Arctic southward into the United States. When a cold front passes your area, you notice the temps usually get colder. This is cold air advection taking place.

Eastern Pacific Ocean: Low pressure moving into the Gulf of Alaska will bring strong winds and heavy snowfall to Alaska. Low pressure over the Southwest US will bring rain, winds and snowfall to a large portion of the region.
Atlantic Ocean: Low pressure is moving over the open Atlantic towards Iceland (Melissa). Low pressure over Western Europe will bring showers to Italy and Spain and snow to the Alps. Low pressure moving through the Middle East will bring showers, thunderstorms and rare flooding to the region.
Western Pacific: Low pressure moving away from Japan will bring a few snow showers to Northern Japan.

Major Weather Impacts Discussion for November 21, 2013:
Day 1-3: High pressure over the Eastern US will bring another nice day to the region. This will extend into the Eastern Lakes and all the way into the Gulf Coast. A new storm system over the Southwest will have large impacts from the Dakotas to Texas and the Southwest with heavy rain, heavy snow and strong winds. High pressure over the Northern Rockies is going to bring some cold air to the Northern Plains with temps in the single digits and wind chill values below zero. The Pacific Northwest will enjoy partly cloudy skies today. High pressure will slide into the Central Plains. Showers will extend ahead of this high over the Ohio River Valley and into the Gulf Coast. A second piece of energy will be over the Southwest bringing another day of showers and snow showers for the region. The period will finish with high pressure dominating most of the US with very cold weather. Low pressure over the Baja will bring showers and snow showers to the Southwest.
Day 4-7: The period will start with high pressure sliding into the Eastern US, while the low pressure over the Baja will move into Mexico bringing showers to Texas. Day five the storm will push into the Gulf of Mexico bringing very heavy rainfall and thunderstorms to the Gulf Coast. High pressure will dominate a good portion of the country. There will be snow showers over the Great Lakes. Day six the low will move into the Florida Panhandle bringing heavy rains to the Gulf Coast and the Southeast. There may be some snow mixed in over Arkansas and Northern Mississippi as well. The period will end with low pressure exiting the Eastern US. Look for another cold high pressure to settle in over a good portion of the US.
Day 8-12: The period will start with a clipper system moving through the Northern Plains bringing light snow to the area as another strong shot of cold air moves into the Plains. Day ten the storm system will push into the Southern Plains bringing rain and snow to the area. The cold air will settle southward. The period will end with high pressure over the Ohio River Valley and low pressure over Texas bringing rain and possibly heavy snowfall to the Southern Plains.
Long Range Outlook: The long range will be very active with multiple storm systems moving through the country with the potential for heavy snowfall from the Dakotas to the East Coast. Along with that, another round of cold air will settle in over most of the United States.
