James Spann: Scattered strong to severe storms forming in Alabama today

James Spann has the midweek forecast for Alabama from Alabama NewsCenter on Vimeo.

SCATTERED THUNDERSTORMS LATER TODAY: Skies are mostly clear in Alabama early this morning with temperatures in the 70s; Today we soar back into the 90s with a partly sunny sky. During the heat of the day, scattered and random thunderstorms are likely to form over the southern two-thirds of the state and could have a major impact. The Storm Prediction Center maintains a slight risk (level 2 of 5) for severe thunderstorms today primarily for areas south of I-59.The main threat of stronger storms will come from strong straight-line winds. Of course, all summer thunderstorms produce a large amount of cloud-to-ground lightning and are efficient rainmakers. It won’t rain everywhere today; the chances of any location seeing a storm are 30-40% south of I-59 and 10-20% in the northern third of the state.

THURSDAY THROUGH THE WEEKEND: We will maintain some risk of isolated afternoon and evening storms in the forecast for Thursday and Friday, but most places will be hot and dry, with highs in the mid-90s. A drier air mass falls into the state on Friday night and into the weekend will feature sunny days, lower humidity levels and cooler nights. Some of the coldest places in North Alabama could reach 50 degrees early Sunday morning; highs will be mostly in the low 90s.

NEXT WEEK: Humidity levels rise again and heat levels remain elevated. Highs will be mostly in the 90s, lows in the 70s, and afternoon and evening showers and thunderstorms should be fairly rare below the upper high. Temperatures are likely to remain above average for the rest of June.TROPICAL ZONE: Satellite images and surface observations indicate a small area of ​​low pressure over the southwestern tip of the Caribbean Sea, near the east coast of Nicaragua. This system is accompanied by showers and disorganized thunderstorms. Development is possible as the system moves northwest near the coasts of Nicaragua and Honduras, and could become a tropical depression later this week if the disturbance continues over water. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the system later today if necessary. Regardless of development, the low could produce periods of heavy rain in parts of eastern Nicaragua and eastern Honduras through the end of this week.

The National Hurricane Center gives the system a 40% chance of developing over the next five days. If anything forms here, it will stay well south of the north central Gulf Coast (places like Gulf Shores, Destin, and Panama City Beach). The rest of the Atlantic basin is very calm.

ON THIS DATE IN 1991: The second largest volcanic eruption of the 20th century began when Mount Pinatubo injected 15 to 30 million tons of sulfur dioxide 100,000 feet into the atmosphere. As a result of the eruptions, 343 people died in the Philippines and 200,000 were left homeless. Material from the explosion would spread across the globe, causing climate changes around the world, as energy from the sun would be blocked and global temperatures would cool by up to one degree Fahrenheit. The following year, 1992, was one of the coldest globally since the 1970s.
