James Spann: A few rounds of storms for Alabama this week; very warm through Thursday

RADAR CHECK: Showers and thunderstorms are moving across the northern quarter of Alabama early this morning; heavier storms are producing small hail and gusty winds. We also note a few isolated showers south of Montgomery. Otherwise, we expect a mix of sun and clouds today with a few widely scattered showers or storms this afternoon. The high will be in the mid to upper 80s in most places; the average high for Birmingham on May 6 is 80.
The weather won’t change much Tuesday. With a partly sunny sky the high will be between 85 and 90 degrees with a few showers or storms; they will be random and scattered, and mostly during the afternoon and evening.
WEDNESDAY/THURSDAY: Looks like Wednesday will be the warmest day so far this year, with many places touching 90 degrees. This will make the air unstable and will open the door for a few strong to severe thunderstorms by afternoon and into Wednesday night. The Storm Prediction Center has defined a severe weather threat for the northern half of the state, and the main concern will come from hail and strong winds. The main dynamic support and wind profiles needed for tornadoes will be north and west of Alabama, based on current model data.
A few lingering showers or thunderstorms are possible Thursday; for now, no severe weather risk is defined since the air could be worked over by storms Wednesday night. The high Thursday will be in the mid 80s.
FRIDAY AND THE WEEKEND: A refreshing, cool, dry air mass will drop into Alabama, setting the stage for sunny, pleasant days and clear, cool nights. Highs will be mostly in the 70s, with lows in the 50s. Colder spots across north Alabama could easily dip into the 40s Saturday morning. We do note some model inconsistencies in the weather Sunday, but we will stick with the reliable European global model, which keeps our weather dry.
ON THIS DATE IN 1967: An EF-2 tornado tore through Birmingham that Saturday evening just west of downtown. Some of the heaviest damage was along Lomb Avenue, near Rickwood Field and the GES store (the Walmart of the day). One person was killed and 25 people were injured along the four-mile path. Two homes were destroyed and 60 damaged. Thirty industrial buildings were damaged.
ON THIS DATE IN 1975: A massive tornado hit Omaha, Nebraska, killing three people, injuring 133 others and causing more than $250 million damage. The tornado struck during the late afternoon, moving northeastward through the industrial and residential areas of west-central Omaha and lifting over the northern section of the city. The twister cut a swath 10 miles long and as much as a quarter-mile wide. It was the costliest in U.S. history at that time.
