Big Story Weather from August 17-19:
On Friday the frontal boundary continued to be the source of severe weather with the majority of the reports being strong wind damage from Texas into the Carolina´s. A few hail reports were also found in Kansas and Texas along with Arkansas. Saturday saw damaging winds in the Southern Plains and also very heavy rain along the Gulf Coast. On Sunday we saw more heavy rain along the Gulf Coast and also isolated hail reports in the Great Lakes and back into the Southwest.

Big Story Weather Outlook for August 20: A frontal boundary just off the Mid-Atlantic will bring a few thunderstorms back to the region, however nice conditions will prevail for places like Buffalo as temps get into the upper 70´s. A stationary boundary will extend across the Gulf Coast bringing scattered showers and thunderstorms to the region, while places like Atlanta will be partly cloudy with temps in the mid 80´s. High pressure will control the weather from the Plains all the way into the Midwest for places like Chicago were the temps will be in the lower 70´s with partly cloudy skies. High pressure will also be in control of the weather over the western two-thirds of the United States bringing partly cloudy skies to places like Denver and Seattle were temps will be in the upper 70´s to lower 80´s. A few thunderstorms will be found in the Southwest along the monsoonal trough.

Big Story Weather International Outlook:
Typhoon Tembin continues to track towards Southeast Asia bringing very heavy rains and strong winds to the region. High pressure will bring partly cloudy skies to places from Tokyo westward into the Korean Peninsula. Interaction between the typhoon and the monsoonal trough will bring heavier rain to Southeast Asia.  Hurricane Gordon continues to track towards Europe. While another strong wave is getting ready to push off Africa within the next 30hrs and head towards the Verde Islands. High pressure will bring partly cloudy skies to the Northern portion of Australia, while two areas of low pressure bring rainy conditions to the southern portion of Australia.
