James Spann: Warming trend, generally dry pattern ahead for Alabama

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

RADAR CHECK: We note some light rain falling early this morning over far north Alabama, but most of the state is rain-free with temperatures generally in the 50s. Expect a partly sunny sky today with a high in the low 80s; the average high for May 13 at Birmingham is 81. Any afternoon showers will be few and far between.

REST OF THE WEEK AND THE WEEKEND: An upper ridge continues to build across the Gulf Coast region, pushing highs into the 80s. Humidity levels will be rising, and while a few isolated showers could pop up each day, odds of any one spot getting wet will be in the 10% to 20% range. Look for partly sunny days and mostly fair nights. Most of the rain and storms will be on the periphery of the upper ridge well to the west and north of Alabama.

NEXT WEEK: Not much change. The ridge stays in place, keeping Alabama in a very warm and mostly dry pattern. Expect highs mostly in the upper 80s, although a few spots could reach 90 degrees for the first time this year. Showers will remain few and far between. I think it is safe to say you can stick a fork in the spring severe weather season for “Dixie Alley”; the action has shifted to the Great Plains.

TROPICS: The National Hurricane Center is expecting a subtropical storm to develop off the U.S. East Coast late this weekend or early next week; it gives a 70% chance of development. The system will move northeast and will remain offshore, but it could bring rough surf and rip current danger to parts of the Atlantic coast.

ON THIS DATE IN 1995: An outbreak produced tornadoes extending from the Mississippi River near Burlington, Iowa, to the west of Bloomington, Illinois. Two violent tornadoes, each ranked at F4 intensity, were reported. The first tornado traveled 60 miles from near Fort Madison, Iowa, to the southeast of Galesburg, Illinois, producing more than $10 million damage. The town of Raritan, Illinois, was hit the hardest. The second violent tornado traveled 7 miles across Fulton County from Ipava to Lewistown, Illinois, producing $6 million damage.
