Big Story Weather from June 29-July 1:
The major story of the weekend was the heat that continued to affect well over 2/3 of the country from the Plains all the way east and south. This weekend´s temps were record breaking for many places as they topped out above 105F. A few places that did have the record heat were Memphis TN, St. Louis MO. Both of these places cleared well over 100F. Another major huge story from the weekend was the Derecho that went from Iowa to Maryland bringing with it winds well over 60mph to many places. The National Weather Service reported on June 29 that there were over 1,000 strong wind reports from this Derecho. Also, a few tornadoes were spawned off of the system. As for June 30, we saw one tornado in Virginia and another associated with Tropical Squalls in Louisiana. On July 1 we saw another day with well over 500 strong wind reports throughout the Mid-Atlantic and Southeast. So what is a Derecho? The best way to answer this is think of a large massive line of thunderstorms that are moving fairly fast. When the gust front or the leading edge of the thunderstorm clouds arrive the winds instantly increase to well over 60mph and this strong increase leads to straight line wind damage.

Big Story Weather Outlook for July 2: The big story of the day will be the heat that will spread from the Northeast all the way back into the Plains and towards the Southeast. Look for isolated thunderstorms in the Northeast. Also, extending back from the Carolina´s into the Gulf Coast there will be a chance to see afternoon isolated thunderstorms.  Baltimore will see partly cloudy skies and a high in the upper 80´s which will be cooler than the last few days. Atlanta will be hot today as temps rise into the upper 90´s to near 100F. Houston will see partly cloudy skies as high temps rise into the upper 80´s to lower 90´s through the region. The Northern Plains will be dealing with a frontal boundary moving through the area which will bring with it scattered thunderstorms. Some will approach the severe level today so be on the watch for possible wind damage and large hail along with isolated tornadoes. Sioux Falls looks for high temps near 90 along with afternoon thunderstorms. Partly cloudy skies will be found from the Rockies westward to the West Coast. Seattle will see high temps in the 70´s with partly cloudy skies.

Big Story Weather International Outlook: A frontal boundary extending through Japan and back to the eastern portion of China will be bringing partly cloudy skies to places like Tokyo and back into Seoul and down the east coast of China. Hong Kong will have isolated showers. High pressure will dominate the Middle East bringing another warm and dry day to the region. Low pressure moving towards England will bring showers and cooler weather. Look for partly cloudy skies to extend into Spain and France. High pressure will be in control of the weather for the majority of Australia today making way for partly cloudy skies and a nice winter day.

Big Story Weather Oceans for July 2, 2012: This morning in the tropics we are watching three areas of interest. The first is located to the southwest of Central America. The estimated pressure is around 1009mb with winds near 20kts. The second location is passing over top of the Philippines this morning with an estimated pressure of 1007mb and winds near 15kts. The third location is to the southwest of Guam. Winds are estimated to be around 20kts with a pressure of 1007mb. 96E is showing the potential to develop in the near term along with 97W.

An adventure to the Land Down Under. If you are taking a trip down under, here are some of the water temps this morning around the country. SST temps around Australia, as they are now into their winter months. The temps off the coast of Perth are between 20-22C, while if you head eastward towards Sydney the temps drop quickly into the 17-19C range. Moving back towards the warmer northern section of Australia near Brisbane the temps warm back into a nice 25-27C range.
