redOrbit Meteorologist Joshua Kelly
Big Story Weather from July 23: The heat was on in the middle part of the United States as many places saw temps reach into the triple digits along with heat index values over 105. The majority of the severe weather was found in the Northeast yesterday extending down into the Mid-Atlantic. Along the frontal boundary, hail and wind damage were the primary reports. Many hail reports came in over 1.5 inches and larger. Heavy tropical rains were found in Florida with a tropical wave that is moving through the area.
Big Story Weather Outlook for July 24: A frontal boundary moving through the Northeast will bring thunderstorms and cooling temps throughout the next 24 hours for places like Boston. The highs will be in the mid 80´s with thunderstorms. Isolated thunderstorms will be found throughout the Mid-Atlantic into the Southeast and Gulf Coast region with places like Gulfport MS seeing high temps in the lower 90´s. Interaction between the high pressure over Canada and the developing low over the Northern Plains will impact the weather for places like St. Louis where they will see high temps in the mid 90´s with isolated thunderstorms during the afternoon. Monsoonal moisture will impact the Southwest today, while a weak area of high pressure will begin to ridge in from the Pacific bringing partly cloudy skies to places like Denver and Seattle. Expect to see high temps in the lower 90´s for Denver and a nice cool 75 for Seattle.
Big Story Weather International Outlook: Typhoon Vicente continues to push on shore over Southeast China impacting places like Hong Kong with very heavy rain and strong winds. Partly cloudy skies will prevail form Japan back west into the Korea´s. The monsoonal trough will continue to bring heavy rain to places like India and the Southeastern portion of Asia. A weak frontal boundary may bring some isolated showers and thunderstorms to the Middle East. High pressure over Central Europe will bring partly cloudy skies to places like France and Spain and also southward into Italy. A weak area of low pressure will move over England today bringing with it mostly cloudy skies and a few passing showers. High pressure off the Pacific coast of South America will bring partly cloudy skies to Peru. High pressure will dominate the weather throughout Australia with partly cloudy skies and light winds.
Big Story Weather Oceans for July 24, 2012: Typhoon Vicente continues to impact Southeast China with very strong typhoon force winds. Impacted regions include the area of Hong Kong. Estimated winds are currently around 100kts with an estimated pressure near 948mb. Also in the Western Pacific there is area 93W which is just to the east of the Philippines with an estimated pressure of 1010mb and winds near 15kts. It will continue to move westward over the Philippines. The Eastern Pacific currently has 90E which has continued to intensify over the last 24 hours with estimated winds now near 30kts with pressure near 1007mb. This feature will probably become the next tropical storm of the Eastern Pacific within the next 24-36 hours. The Atlantic remains quiet this morning.

Tropics Watch: This morning looking at the temps over near the coast of Africa we see that temps range from a small pocket of 27-28C near the coast and then dropping to the 25-26 range off the coast and all the way across the Atlantic. These temps are warm enough to support tropical development, and as we start to work our way into August this is the region to watch for tropical development. However, if El-Nino continues to set up, this region may be very quiet this year.
