Cooler air blew across Alabama Tuesday morning, and more is on the way.

As of 6 a.m. Tuesday, temperatures ranged from a decidedly cold 39 degrees in Gadsden and 43 degrees in Haleyville to a warmer 62 degrees in Mobile, according to surface observations from the National Weather Service.

Temperatures today are only expected to climb into the high 60s in northern Alabama. Forecasts say central Alabama will peak in the upper 60s to low 70s, and southern Alabama will be warmer with highs around 80 degrees.

The weather service said freeze warnings were not out of the question for parts of northern Alabama this week, but had not issued one as of Tuesday morning.

Temperatures are expected to moderate from Thursday and warmer weather is expected over the weekend.
