redOrbit Meteorologist Joshua Kelly
Big Story Weather from September 26: Another severe weather day from the Texas Panhandle all the way northeastward into the Ohio River Valley and parts of the Mid-Atlantic. These areas dealt with strong winds, damaging hail and heavy flooding rains. Also the cool weather was in place over the Northern Plains yesterday morning.
Weather Outlook for September 27: Stationary boundary and the associated low will again create a severe weather setup from the Mid-Atlantic back westward into Texas look for strong winds, large hail as the primary threats. High pressure will be shifting in over the Great Lakes bringing cooler weather to that region and the west will see yet another dry and warm day. Let´s take a look at the weather for a few select cities:
Baltimore MD: P/C (storms) 76F | Mobile AL: P/C 80F | Kansas City: P/C 66F | Denver CO: P/C 64F | San Diego CA: P/C 70F
International Outlook: Tropical moisture will be abundant in the Tokyo Metro area and also along a good portion of the East Coast of Japan. A frontal boundary will begin to move across the Korea´s and Eastern China bringing with it a chance of showers. High pressure over Eastern Europe will provide some relief to Western Europe bringing partly cloudy skies from east to west across the region. England will be dealing with more clouds and showers today. High pressure will be impacting the majority of the Southern portion of South America with partly cloudy skies. Transition between the low to the south and an area of High pressure to the west will bring partly cloudy skies to the majority of Australia.
Atlantic Basin: Tropical Storm Nadine still hanging in strong and showed signs of strengthening. Winds are near 45kts with a drop in pressure to 993mb.
Eastern Pacific: Miriam has been downgraded to a tropical storm as it continues to head over colder waters this morning. Pressure is around 997mb with winds at 45kts. This storm will continue to slowly drift northward and eventually over the Baja. A new area of development has begun to show interest just off the coast of Mexico and does have the potential to develop towards the weekend into another tropical system. Winds are around 25kts with a pressure of 1007mb.
Western Pacific: Super Typhoon Jelawat continues to impact the Philippines with winds in excess of 135kts and a pressure of 922mb. This system will slowly drift northward and have a direct impact in the Okinawa region again with very strong winds. After that it will slowly push northward towards the Kanto Region of Japan. Tropical Storm Ewiniar continues to move slowly northward and is directly south of Tokyo Japan at this time with winds near 55kts and a pressure of 982mb.
ENSO Watch: Conditions are still favorable for the development of El-Nino within the next few weeks.

Major Weather Impacts Discussion for September 27, 2012:
Day 1-3: The frontal boundary and associated low pressure moving through the Southern Plains and Ohio River valley and then towards the Northeast will be the big impact for the day with severe weather possible in these regions.
Day 4-7: The associated low will finally begin to push off the East Coast and the trailing frontal boundary will be in the Gulf Coast region bringing with it showers and storms to the region. The majority of the region will enjoy high pressure for the remainder of this forecast period.
Day 8-12: Interaction between a strong high pressure moving in over Western Canada and a developing low pressure over the Rockies will provide a chance to see some wintry precipitation in the Northern Plains.
Day 13-15: The strong high pressure building in over the Northern Plains will provide some cooler temps. Also the developing low pressure system near Florida will bring an increase in moisture to the Northern Gulf Coast and also up the East Coast, along with another low pressure moving through the Great Lakes.

Ask The Weatherman for September 27:
Question: What side is the worst of the hurricane?
Answer: Every time you listen to a news report, they say that the right, front part of the storm is the worst to be in, but why? Here are a few things that occur. First of all, the winds are strongest in the storm in this area and also rapidly change directions quickly which leads to the increased chance of tornadic storms to form. Secondly, this portion of the storm is where all the water is being pushed up from the ocean on to the shore, these are just a few reasons why this right, front side of the storm is the danger zone.
