Big Story Weather from May 18-20, 2012: The tropics became active over the weekend as our first tropical storm of the season formed off the Carolina coast and spent the weekend drifting southward. Indications are that it´s now moving slowly eastward and should then start turning away from land. Friday brought one tornado to the Wyoming region with the majority of our hail reports also coming from the Dakota´s and Minnesota with isolated spots throughout Florida also. Saturday saw a drastic increase in severe weather with well over 20 tornadoes with the majority found in Kansas and Nebraska and also an isolated tornado reported along the Gulf coast of Florida near St. Petersburg. On Sunday we did not have any reported tornadoes, however, we still had hail from Wisconsin southward along the frontal boundary.

Big Story Weather Outlook for May 21: Tropical Storm Alberto will continue to move off the shore of South Carolina and Florida bringing thunderstorms and increased cloud cover to the region. A frontal boundary will extend from the Great Lakes all the way down into the Gulf Coast bringing with it showers and thunderstorms.  High pressure begins to build in over the Southern Plains which will lead to a very nice day from North Dakota all the way southward into Texas. Partly cloudy skies will extend over the Western United States. The only area of concern will be up in the Northwest Pacific where we will see showers in the Seattle Metro area.

Big Story Weather Outlook International: A weak area of low pressure will move up along the East Coast of Japan bringing with it scattered showers to the capital. Low pressure moving into Europe will bring mostly cloudy skies and showers to England and over into France and Spain for the day. High pressure will be in control of the weather over Australia bringing a nice day to the region.

Big Story Weather Tropics: Tropical Storm Alberto formed over the weekend off the coast of South Carolina and will continue to drift slowly eastward and then northeastward over the next 24hrs. Estimated winds are around 35kts and a pressure near 1000mb. In the Eastern Pacific we are watching TD#2E which has formed just off the coast of Central America with an estimated pressure of 1005mb and winds near 30kts. This system should become a tropical storm later today. In the Western Pacific we have TD#3E which has formed just southwest of Guam and should remain just west of Guam as it increases into a Tropical Storm. Currently estimated winds are near 25kts and a pressure around 1004mb. Outside of these places no other tropical activity is forecasted for today.
