James Spann: Mostly dry week ahead for Alabama; frost possible early Thursday By James Spann PLEASANT SPRING WEATHER CONTINUES: Dry air covers Alabama this morning. We expect a good supply of sunshine today with a high in the low 70s. Tuesday will be partly to mostly sunny with a high between 72 and 75 degrees, still a little below average for mid-April. A significant cold front will pass through the state late Tuesday night and early Wednesday. A sprinkle or two is possible over the Tennessee Valley of north Alabama, but this will be a mostly dry frontal passage with very little moisture to work with. Wednesday will be breezy and noticeably cooler; areas north of Birmingham won’t get out of the 50s despite a clearing sky.
