Ask The Weatherman for December 24, 2013:

Question: What is a CA air mass?

Answer: CA air mass stands for Continental Arctic. This means that the origin of this air mass comes from land, which is why we say continental. It also comes from the Arctic, meaning that it will be frigid air. This type of air is very common in the winter over the United States. Just this year we have seen a lot of these types of air masses already. With this type of air mass it is not uncommon for places in the Northern Plains to fall to around -40F. This air mass is also very dry, meaning not a lot of moisture will fall from it.

December 24, 2013 Storm Tracker Update:

Top Right Image: Tropical Cyclone Bruce. Bottom Right Image: Invest 95S near Australia.

Eastern Pacific Ocean: Low pressure in the Gulf of Alaska will bring more rain, snow and gusty winds to the region. Low pressure to the east of Hawaii continues tracking towards the east and will be nearing the SOCAL region later this week. Low pressure moving out of the Rockies will enter the Northern Plains bringing with it snow, gusty winds and cold temps.

Atlantic Ocean: Low pressure off the East coast of Canada will bring high seas to the open Atlantic. Low pressure near Iceland will bring another day of snow for Greenland and Iceland and showers for Western Europe.

Western Pacific: Low pressure moving into Eastern China will bring snow showers and cold weather to Eastern China. A second low is pushing away towards the Aleutian Islands with high seas and strong winds.

Indian Ocean: Tropical Cyclone Bruce has winds around 45kts and pressure near 989mb as it continues tracking southeastward now away from land. The remains of Amara continue tracking over the open Indian Ocean with winds near 30kts and pressure around 1000mb. This storm will dissipate in the next couple of days.

Southern Hemisphere: Multiple lows moving across the basin today. Impacts are currently being felt across Argentina in the form of showers and isolated thunderstorms. A second low is bringing a few showers and gusty southeast winds to Southern Africa, while the third low is impacting portions of Southeast Australia and into New Zealand with showers. We are also watching an area for possible tropical development over the Northwest part of Australia. Invest 95S currently has winds around 15kts and pressure near 1002mb. This area needs to be watched as it will bring heavy rainfall and gusty winds to Northwest Australia.

Major Weather Impacts Discussion for December 24, 2013:

Day 1-3: High pressure over the Ohio River Valley will bring partly cloudy skies to most of the East Coast and also cold weather to the region. This will extend into the Gulf Coast as well. Low pressure moving through the Northern Plains will bring snowfall to the region. This will extend into the Western Great Lakes. High pressure over the Central Rockies will bring cool and dry weather to the Southwest and most of the West Coast. On December 25th, the low pressure will bring light snow to the Great Lakes, while the rest of the country enjoys partly cloudy skies and cool weather. The period will finish with some light snow over the Northeast. Otherwise high pressure over the Eastern US and the Rockies will dominate the entire country with partly cloudy skies and cool weather.

Day 4-7: The period will start with a tranquil pattern as high pressure dominates most of the country with partly cloudy skies and some warming. On day five another clipper system will push through the Northern Plains bringing with it snowfall to the Plains and into the Great Lakes. On day six another huge area of high pressure will slide into the Northern Plains bringing yet another round of Arctic air to a large portion of the United States. The period will finish with a cold high pressure dominating most of the country. This will provide for partly cloudy skies and very cold temps with many places expected to be 10-20 degrees below normal.

Day 8-12: The period will start with high pressure along the Eastern US. A storm system will push into Mexico and will bring showers over portions of Southern Texas. By day nine the storm system will get organized over the Northwest Gulf of Mexico bringing heavy rainfall to the Gulf Coast. Another storm will be approaching the Pacific Northwest during this time as well. Day eleven will have a storm system moving up the Eastern US. The storm over the Pacific Northwest will bring heavy rains and higher elevation snows to the region. The period will finish with high pressure dominating most of the country.

Long Range Outlook: The period will start with high pressure over both the East and West Coast. Another storm system will begin to take shape over the Gulf of Mexico again bringing rain to Texas and the Gulf Coast. There will also be an area of wintry precipitation over parts of Oklahoma and Arkansas. The middle of the period will have low pressure moving through the Gulf of Mexico bringing cold rain to the Gulf Coast. A new storm system will be pushing towards the Pacific Northwest. Looking into week 2, we will be watching the storm system move up the Eastern US. A possible heavy snow and rain event will take shape for the Mid-Atlantic to the Northeast, while high pressure dominates the rest of the country with another round of cold weather. The period will end with a significant storm along the Eastern US bringing heavy rains, coastal flooding and heavy inland snowfall, while high pressure dominates the rest of the country with another round of cold weather.

Green Energy Report for December 24, 2013:

Wave Energy: There will be large amounts of energy across the Pacific Northwest and also over the Northeast. The Southwest and Southeast along with the Northern Gulf will see moderate amounts of energy today.

Hydro Energy: The best place for long term energy today will stretch from Eastern Montana all the way into the Western Great Lakes. This entire region will see around 1-5 inches of snowfall which will help build the long term energy bases up.

Solar Energy: There will be ample amounts of solar energy from the Southwest into the Southern Plains across the Gulf Coast and up the Southeast Coast into the Mid-Atlantic.

Wind Energy: The best places today will include behind the front over the Northern Plains, over the Great Lakes region with the stronger winds and lastly over the Northern Gulf winds will be in the 15-20mph range which will provide good amounts of energy.

Weather and Your Wallet for Fargo ND:

Low pressure moving through the region today will bring with it accumulating snowfall along with gusty southwest winds that will create blowing and drifting snow.

Dining: Today is a good day to enjoy lunch at work or at home if you’re on vacation now.

Transportation: There will be impacts on the roads today for travelers due to the combination of snow and blowing snow. This will create reduced visibilities. Make sure if you’re traveling to give yourself plenty of time. There will also be some delays at the airport today with a combination of reduced visibilities and also the need for de-icing of airplanes.

Shopping: For all of you last minute shoppers, expect to see some slippery travel on the roads as the snow will be falling and blowing. Make sure to bundle up as it will be cold and windy.

Electricity: There will be an extremely high demand for heating today due to the cold temps. High temps around 18F and low temps near 2F will give the region around 55HDD’s for the day.

Yard Work: If you’re going to be removing snow from the driveways, make sure to take it easy and give yourself time.

Construction: Indoor projects will be the best for today. There will also be an increase in snow removal projects today.

Outdoor Venues: Today will be an excellent day to reschedule any outdoor events you may have had.
