Big Story Weather – December 5, 2013
redOrbit Meteorologist Joshua Kelly
Big Story Weather from December 4:
The big news from yesterday included the heavy snowfall from the Plains to the Rockies with some places seeing over 9 inches. Cold air settled in over the North with places from Montana to South Dakota seeing temps around -15 to -25F. Heat was in place over the Southeast with temps rising to near 80F. This has been leading to one of the largest temp contrasts that I have seen in a very long time. From north to south we are looking at 100 degree temp change, if not greater.
Big Story Weather Discussion for December 5:
Surface Map 11AM: Low pressure moving into Southeast Canada will bring a trailing cold front all the way to the Gulf Coast. There will be interesting weather with this. Look for rain ahead of the front from New York to the Gulf Coast. Behind the front the Arctic air will invade creating a large area of freezing rain and ice from the Tennessee River Valley into Arkansas, Northern MS, Northern LA and back into Oklahoma and Texas. Some of these places will also see snow mix in as well. A second low pressure is building over Southern Texas. This will enhance the warm air that will go up and over the cold surface layer setting the stage for another pocket of freezing rain over Texas. The Arctic High will be building in over the Northern Rockies and the Northern Plains. High temps will not rise above the zero mark for many locations today.
Surface Map 11PM: Low pressure will push into the Northeast. This will lead the trailing cold front to extend all the way to the Gulf Coast. Look for rain showers and isolated thunderstorms ahead of this front. The thunderstorms will be confined to the Gulf Coast. Behind the cold front the cold air will filter in and will bring not only cold air, but also a wide area of freezing rain from Southern Illinois into Arkansas and Texas and Oklahoma. These conditions are going to be very dangerous to travel. Snowfall will be in place from the Western Great Lakes to parts of Texas and Oklahoma in the colder air. The Arctic High will surge further south overnight bringing very cold air southward. Temps over the Northern Plains will fall into the -30F range overnight along with wind chill values near -50F – very dangerous weather.
Severe Weather: There is a small area of concern along the immediate Gulf Coast from Louisiana to Alabama. The biggest threat looks to be damaging winds.
Winter Weather: There are now winter storm watches/warnings in effect from the Great Lakes all the way southward into Texas and Oklahoma. This morning the winter storm watches/warnings have also now spread eastward into the Lower Mississippi River Valley. The biggest story in this region will be the threat for a large ice outbreak that could lead to serious troubles as power lines will be prone to falling which could leave many areas in the dark and also the cold which is very dangerous. Snow will fall over the Western Lakes to Texas. This area will see periods of heavy snow along with very cold air. There are ample amounts of wind chill watches/warnings in effect for the Northern Rockies and the Northern Plains as some places will see wind chill values fall to the -40F and -50F range overnight along with air temps in the -20 to -30F range. Frost and Freeze advisories are in place for portions of SOCAL and the Southwest extending into Central California due to temps falling to near record lows over this region.
Winds: There will be two areas of concern today. The first will be over the Great Lakes near the surface low. Winds could hit the 40-45mph range. The second will be over the Plains near and behind the cold front where winds will gust in the 30-45mph range.
72hr Westward Storm Watch: Storm 1 is pushing across the Eastern Pacific and headed towards SOCAL. This will bring rain to the valleys and higher elevation snows towards the weekend. Storm 2 is now pushing into Western Alaska and will bring a combination of snow and ice to Alaska.

Ask The Weatherman for December 5, 2013:
Question: What type of atmosphere creates fog?
Answer: There are multiple types of fog. For this question we will address advection fog. This is created by light winds when they blow warmer air over top of colder air. This type of fog is very common along SOCAL and also the Gulf Coast as the air blows from the warmer waters and pushes over top of the colder land.

December 5, 2013 Storm Tracker Update:
SST Analysis (right image): The ENSO Phase remains in the neutral phase.
Eastern Pacific Ocean: Low pressure to the south of Hawaii will bring high surf to the region. Low pressure moving towards Alaska will bring snow showers and freezing rain to the region. Low pressure moving over the Southwest US will bring winter weather to the region.
Atlantic Ocean: Low pressure near the Great Lakes will bring rain, snow and ice to a large portion of the Midwest. An area of low pressure to the west of Africa is being watched for possible tropical development. Winds are now around 50kts. Low pressure moving through Central Russia will bring snow and cold to the region.
Western Pacific: Low pressure pushing away from Guam and to the northeast will bring high seas to the open waters.
Indian Ocean: A tropical wave to the east of India is being watched for possible tropical development.
Southern Hemisphere: Three waves of importance moving through the basin. Look for showers and thunderstorms over Southern South America. Showers and thunderstorms are also possible over South Africa. A third low moving into Southern Australia will bring showers and thunderstorms to the region.
Major Weather Impacts Discussion for December 5, 2013:
Day 1-3: Low pressure near the Great Lakes will bring rain to the East Coast. This will extend into the Southeast and Gulf Coast as well. We may see some isolated thunderstorms along the Gulf Coast. Behind the cold front, look for an area of ice to develop from Eastern Texas into Southern Illinois. The hardest area of impact looks to be the state of Arkansas. Snowfall is in store from the Great Lakes into portions of Oklahoma and Texas. Arctic high pressure will bring very cold air with temps falling to the -20 to -30F range over the Rockies and Northern Plains. Day two a major winter storm will be impacting areas from Texas to Ohio and across portions of the Gulf Coast. Look for multiple places to be recording dangerous amounts of ice along with snow and cold rain. The Arctic high will slide further south bringing the cold air to the Southern Plains. A new low pressure will be pushing into the Pacific Northwest with showers and snow showers. The period will finish with a cold front extending from the Northeast to the Gulf Coast, while the Arctic High will push into the Missouri region bringing very cold air to many places again through the region. Low pressure will slide into the Southwest US setting the stage for more winter weather.
Day 4-7 The period will start with another low pressure area over Western Texas. This will bring showers, snow showers and more ice from Texas to the Mid-Atlantic, including the Gulf of Mexico. Another Arctic high will slide into the Pacific Northwest. Day five a storm system will extend across the entire East Coast and Gulf Coast with showers, ice and snow. High pressure will dominate the weather from the Plains to the West Coast with another shot of cold air for many places. The period will finish with another storm system entering the Pacific Northwest.
Day 8-12: The period will start with an Arctic high bringing cold air from the East Coast to the Plains and into the Gulf Coast. The next storm system will push through the Pacific Northwest and into the Northern Rockies with snow showers and gusty winds. Day ten we will have another winter storm on our hands with more rain, snow, ice, thunderstorms from Texas to the Ohio River valley into the Gulf Coast and Southeast. The period will finish with a major storm system covering from the Midwest to the Northeast and into the Gulf Coast and Southeast with plenty of rain, snow, ice and thunderstorms.
Long Range Outlook: The period will start with another Gulf Low developing and moving northward along with another shot of Arctic Air. This will create yet another winter storm with plenty of rain, thunderstorms, snow and ice for many places from the Southern Plains to the Great Lakes and through the Gulf Coast. Another powerful storm will enter the Pacific Northwest during this time as well. The middle of the period we will have a major winter storm along the East Coast, an Arctic High in the middle of the US, and another powerful storm system over the Pacific Northwest.
Green Energy Report for December 5, 2013:
Wave Energy: There will be ample amounts of wave energy from the Northeast all the way into the Gulf Coast ahead of the strong cold front. The entire West Coast will again see high amounts of energy due to the continued flow of storm systems over the region.
Hydro Energy: There will be plenty of short term energy from the Gulf Coast into portions of the Tennessee River Valley. There will be a combination of short and long term energy from Eastern Texas to Missouri. There will also be an area of long term energy from Western Texas to Ohio. There will be large amounts of long term energy over the Colorado Rockies and portions of the Southwest US.
Solar Energy: The best place for solar energy today will be over Southern Florida. Look for a good share of energy over SOCAL and parts of the Pacific Northwest.
Wind Energy: There will be ample amounts of wind energy from the Great Lakes to Texas along the cold front.
Weather and Your Wallet for Fargo ND:
Arctic high pressure will begin to settle into the region. Expect to see cold weather and dangerous wind chill values approaching -60F.
Dining: It would be wise to stay indoors and eat at the office today.
Transportation: There will be moderate delays on the roads today as blowing and drifting snow will create slowdowns on the roads. The airport will also see delays due to the cold weather.
Shopping: Today will be a day to run quickly from the car to the mall as the cold weather will be in full force.
Electricity: The region will have a high demand for heating all day long. High temps around 7F and low temps near -4F. This will bring a 24hr total of HDD’s near 64.
Yard Work: If you have plans to clean the snow today, take it easy as it’s going to be really cold.
Construction: The best jobs today will be those indoor projects that have heat around them. Outside work will be dangerous and could lead to frost bite in a short period of time if not dressed properly.
Outdoor Venues: Today will be a good day to reschedule any outdoor plans. If you have pets, make sure to bring them inside during this cold weather.
