James Spann forecasts a dry weekend for Alabama with lower humidity from Alabama News Center on Vimeo.

MOSTLY DRY WEATHER CONTINUES: The chance of any one spot seeing rain across Alabama today remains 10% or less; with a partly sunny sky, we project a high in the low 90s for most places this afternoon. The average high for Birmingham on Aug. 9 is 91.

For the weekend, a drier, continental air mass drops in from the north. This will mean lower humidity and cooler nights; lows will be in the mid to upper 60s over the northern half of the state early Sunday and Monday mornings. Highs will be close to 90 Saturday and Sunday.

NEXT WEEK: The quiet pattern continues. We will mention the risk of a few isolated showers over the latter half of the week, but still no chance of any widespread rain. Highs will be mostly in the low 90s, with lows in the low to mid 70s.

TROPICS: The remnant circulation of former Tropical Storm Debby is near the Virginia/North Carolina border this morning and will accelerate to the northeast today, bringing periods of heavy rain to the northern half of the eastern seaboard.

A tropical wave over the tropical Atlantic several hundred miles west-southwest of the Cabo Verde Islands is producing widespread disorganized showers and thunderstorms. Any development of the wave should be slow to occur during the next couple of days while it moves westward across the central tropical Atlantic.

Afterward, conditions are expected to become more conducive for development, and a tropical depression could form while it approaches the Lesser Antilles by early next week. The system is then forecast to move generally west-northwestward and could approach the Greater Antilles by the middle part of next week. The National Hurricane Center gives it a 50% chance of development. If a tropical cyclone does form, it will likely turn north before reaching the U.S. or the Gulf of Mexico, based on the forecast upper air pattern, in seven to 10 days.

ON THIS DATE IN 1878: The second-deadliest tornado in New England history struck Wallingford, Connecticut, killing 34 people, injuring 100 others and destroying 30 homes. The tornado started as a waterspout over a dam on the Quinnipiac River. It was 400 to 600 feet wide and had a short path length of two miles. The deadliest New England tornado occurred in 1953 when an F4 killed 90 people in Worcester, Massachusetts.

ON THIS DATE IN 1969: An F3 tornado hit Cincinnati, Ohio, killing four people and causing $15 million property damage.
