James Spann: Hotter, drier weather for Alabama later this week

RADAR CHECK: We have a number of showers and strong thunderstorms across Alabama this afternoon. They are moving eastward, and stronger storms are producing very heavy rain, gusty winds and frequent lightning. The Storm Prediction Center maintains a low-end, marginal risk (level 1 of 5) for the northern half of the state through the evening.

Showers and storms will fade away after sunset.

The weather won’t change much Tuesday; it will be partly sunny with scattered showers and thunderstorms developing by afternoon. Odds of any one spot getting wet will be in the 50% to 60% range and the high will be close to 90 degrees.

WEDNESDAY THROUGH FRIDAY: An upper ridge will strengthen over the Deep South, meaning hot and mostly dry weather on these three days. Look for partly sunny days, fair nights and highs between 91 and 94. The chance of a shower is not zero, but they should be few and far between.

LABOR DAY WEEKEND: Heat levels will come down; we expect highs in the mid to upper 80s Saturday through Monday. Showers should be widely scattered Saturday, then a bit more numerous Sunday and Monday (but no washout). As usual, most of the showers and storms will come during the afternoon and evening hours.

NEXT WEEK: A pattern change will bring two fronts into the state. The first one arrives Monday, the second one most likely Wednesday. There will be a chance of showers and storms with each front, and following the second one we expect a nice surge of cooler air with lower humidity. By Thursday and Friday of next week highs drop into the low 80s, with lows in the 50s over a decent part of north Alabama.

TROPICS: The National Hurricane Center is monitoring three tropical waves. One is expected to emerge off the coast of Africa in a day or two. Gradual development of this system will be possible through the end of the week while it moves slowly westward over the far eastern tropical Atlantic Ocean. There’s no way of knowing now whether this will affect the U.S. If it does, it is at least seven to 10 days away.

A broad area of low pressure associated with a tropical wave over the central Caribbean Sea has changed little in organization since Sunday, and satellite-derived winds indicate there is no closed circulation. However, environmental conditions are expected to gradually become more conducive for development, and a tropical depression is likely to form during the next couple of days while the system moves westward at 15 to 20 mph. Odds are high that this system will keep moving westward into Central America without moving northward into the Gulf of Mexico.

An area of low pressure is about 135 miles southeast of Wilmington, North Carolina. This system continues to become better organized, and a tropical depression is expected to form later today or tonight while the system moves northeastward, near but offshore of the southeastern coast of the United States and then away from land. An Air Force Reserve Hurricane Hunter aircraft is en route to investigate the system this afternoon.

There are no systems threatening the Gulf Coast for the Labor Day weekend; the weather looks routine there, with the usual mix of sun and scattered thunderstorms.

ON THIS DATE IN 1935: The most intense hurricane to make landfall was a modest tropical depression on this day. Called the Labor Day Hurricane, this storm went through phenomenal intensification to become a Category 5 hurricane by Sept. 2.
