Surface Map 11AM: High pressure will make for a pleasant fall day up and down the East Coast. This will extend back into the Ohio River Valley and the Gulf Coast. High pressure will push into the Northern Plains as well bringing cold air to the region. Powerful low pressure will push into the Rockies bringing heavy snowfall to all high elevations of the west and will also start to push into the Western Plains with showers will stretching into SOCAL.
Surface Map 11PM: High pressure will push into the Great Lakes overnight. The strong storm system will push into Utah and Colorado bringing heavy snowfall to the Rockies and into the Plains. Near blizzard conditions will be possible due to the strong winds as well. Thunderstorms will also develop over the Southern Plains.
Severe Weather: Later this afternoon and evening there will be an area of severe weather possible over Kansas and Oklahoma. The primary threat will be damaging winds, however an isolated tornado will also be possible.
Winter Weather: A major winter storm will bring impacts for the West into the Rockies and spread into the Northern Plains. Snowfall totals will range from 4-6 inches over the Plains to well over 1ft in the higher elevations of the Rockies and upwards to 1ft in the higher elevations of the West.
Flooding: There will be the continued threat for flooding over Southeast Texas and also over the majority of Hawaii.
Tropical Weather: No impacts across the Atlantic Basin.
Winds: Strong gradient winds behind the cold front will bring 40-50mph winds to the Western Rockies. There will also be strong winds ahead of the storm due to gradient induced winds from the strong high to the east. Winds of 30-40mph will be possible over the Plains.

Ask The Weatherman for October 25, 2013:
Question: What is convergence?
Answer: The term convergence can be used to identify many things in weather. The basic term means to merge something together. For weather, when the winds meet each other, they are converging together. This is very common in the upper level jet stream pattern. The winds converging together can also lead to instability which can in return lead to thunderstorms.

October 28, 2013 Storm Tracker Update:
Latest Right Image: Tropical Storm Raymond continues to hold just to the southwest of the Baja and is slowly drifting northeastward.
Eastern Pacific Ocean: Tropical Storm Raymond has winds around 45kts and pressure near 1001mb and is continuing to track slowly towards the Baja. Showers over Hawaii will bring another day of potential flooding to the region. Low pressure will move into the Gulf of Alaska again bringing rain and snow to the region. Low pressure moving into the Rockies will bring significant snows, heavy rains and severe weather to the Rockies and the Plains.
Atlantic Ocean: Low pressure off the east coast of Canada will bring showers to Greenland. A very powerful storm system will move into Western Europe bringing heavy rains, flooding and damaging winds to places from England to Spain and France.
Western Pacific: Low pressure moving through Central China will bring showers and snow showers to the region. An area of low pressure to the northwest of Guam is being watched for possible tropical development.
Indian Ocean: Multiple lows moving through the basin will have limited impacts over land and should remain over open waters.
Southern Hemisphere: Low pressure moving to the south of South America will bring showers to Argentina and Chile. Another area of low pressure to the south of South Africa will bring gusty winds to the area.
Major Weather Impacts Discussion for October 28, 2013:
Day 1-3: High pressure along the East Coast will keep the region nice today. This will extend into the Gulf Coast and also the Ohio River Valley. High pressure will also quickly slide through the Northern Plains today bringing another shot of cooler weather to the region. The strong low pressure system will take shape over the Southwest and Southern Rockies today. Look for heavy snowfall from the Sierra Nevada’s to the Cascades and into the Rockies. There will also be a pocket of freezing rain over portions of Western Nebraska. Look for severe weather to develop over Oklahoma and Kansas later today. Snowfall totals will be around 6-12 inches mostly in the Rockies with some isolated higher amounts. Day two high pressure will dominate the Eastern US and the West Coast as low pressure pushes into the Plains. Look for severe weather from Kansas to Texas. Showers and snow showers will push across the Northern Plains. The period will end with high pressure over the East Coast, while the storm system moves into the Mid-Mississippi River Valley. Expect to see severe weather extend from the Gulf Coast to the Arkansas and Tennessee region. Showers will extend northward towards the Great Lakes and some snow showers will still be over the Northern Plains.
Day 4-7: The period will start with a strong low pressure area in the Great Lakes bringing rain and snow to the Western Lakes. Showers and thunderstorms will extend from Chicago to the Gulf Coast. Expect to see some severe weather over the Gulf Coast as well. High pressure will dominate the weather for both the West and East coasts. Day five the storm system will push into the Northeast. Look for rain and snow over the Eastern Lakes and also in the Northeast. Showers and thunderstorms will be possible from the Mid-Atlantic to the Gulf Coast. Some severe weather will be possible along the Gulf Coast. Day six the storm system will push off the East Coast, while a cold area of high pressure settles into the Plains and the Gulf Coast. A new storm system will begin to approach the Northwest. The period will end with high pressure dominating the weather from the East Coast to the Plains and the Rockies, while rain and snow pushes across the Northwest and portions of the Northern Rockies.
Day 8-12: The period will start with high pressure over the East Coast. The storm system will move into the Rockies bringing showers and snow showers. A small piece of energy will also push into the Southwest bringing a few showers to the region. Day nine high pressure will be along the East Coast. Two storm systems will impact the Plains. One over the Northern Plains will bring rain and snow to the region. The second will bring rain and thunderstorms to the Southern Plains. A new storm system will enter the Pacific Northwest as well. Day ten the storm system will move into the Great Lakes. Look for rain and snow showers over the lakes. Rain and thunderstorms will extend from the Ohio River Valley to the Gulf Coast. There will be another storm system entering the Pacific Northwest during this time.
Long Range Outlook: The period will start with high pressure over the Eastern US extending back into the Plains and the Gulf Coast. The storm system in the Pacific Northwest will bring showers to the region along with higher elevation snows. The potential is there for a possible tropical wave to develop to the southeast of Puerto Rico as well. The middle of the period will have most of the US experiencing high pressure and tranquil weather. The period will finish with a new low developing over the Southwest US, while another low pressure begins to push into the Pacific Northwest.
Green Energy Report for October 28:
Wave Energy: There will be moderate levels of energy along the entire East Coast extending into the Gulf Coast. There will be extreme levels of energy over the Southwest Coast which could lead to flooding issues for the area. The Pacific Northwest will have moderate levels of energy.
Hydro Energy: There will be ample amounts of short term energy over SOCAL. The Rockies, Cascades and the Sierra Nevada’s will all have moderate amounts of long term energy. This will expand out into the Plains as well.
