RADAR CHECK: Isolated showers and thunderstorms persist across northeast Alabama this afternoon; a few of them are producing heavy downpours along with frequent lightning. But most of the state is dry with a partly sunny sky. Temperatures are between 87 and 92 for most communities.
Showers and storms will fade away tonight as the air cools and becomes more stable.
FRIDAY THROUGH THE WEEKEND: An upper ridge will ease into the region from the west, meaning few, if any, showers and hotter afternoons. Look for mostly sunny days and fair nights. The high will be close to 90 Friday, followed by low to mid 90s over the weekend. The chance of any one spot getting wet all three days is only 5-10%.
NEXT WEEK: Moisture levels will rise a bit and the weather looks very routine for August in Alabama — partly sunny, hot, humid days with random, scattered, mostly afternoon and evening showers and storms. Highs will be mostly in the low 90s, right at seasonal averages for this time of the year.
TROPICS: The Atlantic Basin is quiet, and tropical storm formation is not expected through the weekend.
NOAA issued its updated hurricane season outlook this morning. Some notes from that release:
“This is one of the most active seasonal forecasts that NOAA has produced in its 22-year history of hurricane outlooks. NOAA will continue to provide the best possible science and service to communities across the nation for the remainder of hurricane season to ensure public readiness and safety,” said U.S. Secretary of Commerce Wilbur Ross. “We encourage all Americans to do their part by getting prepared, remaining vigilant and being ready to take action when necessary.”
The updated outlook calls for 19-25 named storms (winds of 39 mph or greater), of which seven to 11 will become hurricanes (winds of 74 mph or greater), including three to six major hurricanes (winds of 111 mph or greater). This update covers the entire six-month hurricane season, which ends Nov. 30, and includes the nine named storms to date.
Current oceanic and atmospheric conditions that make an “extremely active” hurricane season possible are warmer-than-average sea-surface temperatures in the tropical Atlantic Ocean and Caribbean Sea, reduced vertical wind shear, weaker tropical Atlantic trade winds and an enhanced west African monsoon. These conditions are expected to continue for the next several months. A main climate factor behind these conditions is the ongoing warm phase of the Atlantic Multi-Decadal Oscillation, which reappeared in 1995 and has been favoring more active hurricane seasons since that time.
Another contributing climate factor this year is the possibility of La Nina developing in the months ahead. Indicative of cooler-than-average sea-surface temperatures in the equatorial regions of the eastern Pacific Ocean, La Nina can further weaken the wind shear over the Atlantic Basin, allowing storms to develop and intensify.
ON THIS DATE IN 1993: Virginia experienced its worst tornado outbreak ever as 18 tornadoes ripped through the state in five hours. The most devastating tornado caused severe damage in the historic part of Petersburg. The storm then moved on to Pocahontas Island and into Colonial Heights. There, the storm ripped apart a Walmart store, killing three people and injuring nearly 200. The F4 twister was the first known violent tornado in Virginia history. It killed four people and injured 246 along its 12-mile path.
