Big Story Weather Discussion for August 14:
Surface Map: Low pressure pushing off the East Coast will leave the trailing cold front over the East Coast and back into the Gulf Coast. This will be the focus of showers and thunderstorms. Very heavy rainfall possible over the Gulf Coast which could lead to flooding. High pressure sliding in over the Ohio River Valley will bring nice weather to the region. This will extend into the Great Lakes as well. High pressure over the Rockies will bring partly cloudy skies and very warm weather to the region. The Northwest will also be very warm, while the southwest monsoon will bring another day of showers and thunderstorms to the region.
Severe Weather: Today we are looking at the potential for flooding rains and damaging winds along the East Coast. Along the Gulf Coast it will mostly be flooding rains. The Southwest will see heavy rains and large hail along with some damaging winds. The Central Plains into the western Great Lakes will be the focus for heavy rains, damaging winds and also large hail.
Tropical Weather: We are now watching two regions for possible tropical development. The first is just to the southeast of the Yucatan Peninsula. This area now has winds around 20kts and a pressure near 1009mb. There are favorable conditions in place for more development as it moves towards the Gulf of Mexico. People from Louisiana to Florida at this time need to be on watch for this system as a possible landfall may occur Friday into Saturday. The second area being watched just pushed off the coast of Africa. The winds with this region are around 20kts with pressure near 1010mb. This feature will move slowly to the west over the next few days.

August 14, 2013 Storm Tracker Update:
Eastern Pacific Ocean: Low pressure to the southwest of Hawaii is being watched for possible tropical development. Low pressure moving into Alaska will bring more showers to the region. Low pressure moving towards Western Canada will bring showers to the region. Another area is being watched just to the west of Mexico for possible tropical development.
Atlantic Ocean: Low pressure near the Yucatan Peninsula is being watched for possible tropical development as it pushes into the Gulf of Mexico and possibly makes landfall over the Northern Gulf Coast. Winds are around 20kts and pressure near 1009mb. Low pressure moving away from the Northeast will bring another day of showers and thunderstorms along the East Coast back into the Gulf Coast. A second wave that pushed west of Africa is also being watched for possible tropical development. Winds are around 20kts and pressure near 1010mb at this time. Low pressure moving towards Iceland will bring showers to the region. A second low pressure moving through Northern Russia will bring showers to places like Moscow.
Western Pacific: Typhoon Utor is making landfall along Southeast China at this time with winds gusting well over 60mph for many places. High storm surge has been inundating locations along the coast. Winds have creating a lot of damage and there is also significant flooding. Low pressure to the southwest of Guam is also being watched for possible tropical development. Low pressure moving over Northeast Russia will bring showers to the region. These showers and thunderstorms will extend into Northern Japan as well.
Indian Ocean: The monsoonal rains will continue to create havoc over India and Sri Lanka leading to more flooding.
Southern Hemisphere: Multiple areas of low pressure are moving through the basin again today. One area of low pressure is bringing showers and snow showers to Southern Chile and Argentina. A second low pressure is moving through Southern Africa with showers and gusty winds. A third low pressure is impacting Southwest Australia with showers and gusty winds.

Ask The Weatherman for August 14, 2013:
Question: What is offshore flow?
Answer: Yesterday we looked at onshore flow. Today we will look at the reverse known as offshore flow. This is when the winds are moving from land to the water. This type of scenario is very common in the United States along the Gulf Coast, especially during the summer.
