Big Story Weather – September 26, 2012
redOrbit Meteorologist Joshua Kelly
Big Story Weather from September 25: A big day in the severe weather arena as our frontal boundary gained a lot more strength than I thought it would and was responsible for tornadoes in and around Indiana. There were multiple reports of large hail from Indiana westward through Missouri and southward back into the Southern Plains from Kansas to Texas. We also saw a lot of wind damage reports in the same area yesterday. The rainfall rates were heavy enough that a few places even had to deal with flash flooding on top of all the severe weather.
Weather Outlook September 26: Stationary boundary and an associated low pressure will bring heavy rain, thunderstorms and severe weather from Texas eastward towards the Ohio River Valley and overnight into the Northeast. High pressure will bring another nice day to the Northern Plains and westward into the Rockies and also the West Coast. Here is the weather for a few select cities:
Boston MA: P/C (Evening storms) 75F | Tampa FL: P/C (storms) 88F | Memphis TN: T/S 85F | Billings MT: P/C 77F | Las Vegas NV: P/C 83F
International Outlook: A tropical storm will bring increased rain towards mainland Japan today, while it will remain mostly cloudy for the Korea’s. High pressure over the Tibetan Plateau will bring partly cloudy skies to the region and also decrease the monsoonal rains for Southeast Asia. Low pressure moving over Eastern Europe will make for a rainy and cool day in this region from Germany westward into France. England will be in the middle of high pressure and the area of low pressure resulting in a mostly cloudy day. High pressure will bring a nice day to the southern portion of South America. Low pressure south of Australia and the associated cold front will bring some scattered showers to the Southern portion of Australia.
Atlantic Basin: Tropical Storm Nadine still hanging in strong out over the Eastern Atlantic with winds near 40kts and a pressure of 998mb. This storm is drifting very slowly.
Eastern Pacific: Miriam has been downgraded to a Tropical storm as it continues to head over colder waters this morning pressure is around 990mb with winds at 60kts. This storm will continue to slowly drift northward and eventually over the Baja.
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 towards Japan and may impact the central part of Japan over the next few days. Tropical Storm Ewiniar continues moving just north of Iwo To and is headed to the east of Tokyo, however it will bring stronger winds and higher surf to the east coast of Japan along with some passing showers.
ENSO Watch: Conditions are still favorable for the development of El-Nino within the next few weeks.
Five Day Storm Index Outlook:
Boston MA: This evening showers/storms will begin to make their way into the area expect to see a slight impact today through the next couple of days.
Tampa FL: There will be a slight chance of impacts today, however a moderate chance of impacts as storms begin to increase in coverage during the afternoon hours for the remainder of the days.
Memphis TN: The frontal boundary will be near the area today bringing a moderate chance of storms and impacts, followed by three days of seeing more slight impacts as the boundary slowly drifts away from the area.
Billings MT: A tranquil week of warmer conditions and also drier weather will leave no impacts on the area.
Las Vegas NV: A great week to head out to Vegas as they will be warm and dry for the most part of the next five days.

Major Weather Impacts Discussion for September 26, 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: A very strong 1044mb high and a weak frontal boundary will begin to move into the Northern Plains section providing the region a chance to see some snowflakes along with colder weather. Another developing low will start to take shape of the coast of Florida and begin making its way up the coast.
Day 13-15: The strong high pressure will continue to ridge into the Plains and slowly start pushing eastward. Ahead of it a new low will begin to develop and this low will have plenty of showers and storms with it and also the potential to see some wrap around snowflakes in the Northern Michigan area.

Ask The Weatherman for September 26:
Question: What is storm surge?
Answer: Today’s question comes from Hurricane land. When we hear the word storm surge we think of hurricanes. Storm surge is the rapid rise in water above normal levels. This happened during Hurricane Katrina when the Mississippi Gulf Coast saw the waters rise to 24ft or higher in some places. That rapid rise of water is called storm surge. Storm surge is created by intense winds that blow onshore for long periods of time.
