redOrbit Meteorologist Joshua Kelly
Big Story Weather from September 17: The heat continued in the Southwest, while the Gulf Coast got hit with heavy rainfall amounts between 1-3 inches and some higher amounts. The frost hit the pumpkins in the North and it evened snowed in Colorado. One tornado was reported in Kansas along with damaging winds along Lake Michigan and also a few reports in Kansas, Texas, Tennessee and southern Alabama.
Weather Outlook for September 18: A strong cold front will be pushing through the Northeast bringing with it strong to severe thunderstorms from Boston all the way southward into the Northeast part of the Gulf Coast region to places like Gulfport, while temps will range from the 70´s along the northern part of the front to 80´s along the southern part of the front. High pressure will be in control of a vast area of the remainder of the United States from the Plains westward into the Rockies and along the West Coast. Places like Sioux Falls will see temps in the lower 60´s, while Billings will be in the lower 80´s and Seattle will be near 80. All these places will see partly cloudy skies.
International Outlook: The remains of Sanba will spread showers across portions of Japan and the Korea´s. High pressure over the Himalayas will create a cease to the monsoonal rains over Southeast Asia. High pressure will also be in control over the Middle East making for a hot day. High pressure over Eastern Europe will bring partly cloudy skies to Germany and Italy along with France and portions of Spain, while an area of showers will still impact England. Tropical Storm Nadine will be impacting the Azores islands today. An area of low pressure south of the South American tip will interact with the high pressure to the north bringing a very strong gradient wind to the region today. The majority of Australia will be dealing with nice weather.
Atlantic Basin: Tropical Storm Nadine continues to track over the Azores islands with winds around 50kts and a pressure of 990mb. This storm should slowly begin to weaken. There is another area 92L that is just near the Windward Islands that has shown a little enhancement in convection since yesterday. The winds are estimated around 15kts with a pressure of 1013mb.
Eastern Pacific: Hurricane Lane remains a CAT 1 storm slowly drifting towards the west. Winds this morning are around 65kts with a pressure of 989mb.
Western Pacific: There is one area of concern this morning and that is 92W which is located to the east of the Philippines. It has estimated winds of 15kts and pressure of 1010mb.
ENSO Watch: The neutral phase is still occurring, but the convection along the Tropical Pacific has indications that we will start to see El-Nino towards the end of this month.

Major Weather Impacts Discussion for September 18, 2012:
Day 1-3: A strong cold front will move through the Northeast and Mid-Atlantic region bringing the chance for severe weather today. High pressure behind it will bring some of the coldest air of the season to the Plains and Great Lakes areas. A clipper system will move through the Great Lakes region by day 2 and 3.
Day 4-7: A strong cold area of high pressure will begin to move into the Plains and the Southeast bringing cooler weather.
Day 8-12: A strong storm system will move into the Gulf of Alaska bringing strong winds and heavy rain to the region along with high seas along the Pacific Northwest.
Day 13-15: A push of tropical moisture may return to the Gulf Coast region by this time period.

Ask The Weatherman for September 18:
Question: Why are some high pressure systems warm and others cold?
Answer: Thanks for the great question, the best way to look at this answer is to understand that there are two types of high pressure centers, one is called a warm core and the other is a cold core. The warm core high is the Bermuda Azores High or the Pacific High. These high pressure centers are semi-permanent features that are found over the oceans and migrate towards land in the summer bringing really warm conditions to places. The Canadian High is a cold core system which brings cold air down from Canada and impacts our area with cool-cold temps and clear skies.

Green Energy Weather Report for September 18:
*NEW* Our Green Weather Report will help you monitor the conditions of your new Green Energy sources and how their production will handle today´s weather conditions.
Wave Energy: Two favorable spots appear today. The first is along the Pacific Northwest as the continued seas move in from the Gulf of Alaska Low. The second favorable spot for wave energy today is along the Mid-Atlantic as our frontal boundary approaches look for an increase in wave action.
Solar Energy: Plenty of sunshine available for the Southwest making it a great place for solar energy today along with the Rockies and even into the Northern Plains as the high pressure settles into the region.
Wind Energy: Today´s big wind energy winner is on the back side of the cold front up in the Great Lakes region. The strong Northwesterly flow off the lakes will help increase winds to a very favorable speed to create wind energy today.
