freeze warning concerns are rising as rain exits Alabama and colder air settles in, setting up a clear, cold night and a late-season freeze early next week across much of the state’s northern zones.
What Happens When the rain clears and colder air moves in?
The immediate severe weather threat has ended in Alabama, with the earlier line of strong to severe thunderstorms leaving the southeast corner of the state shortly after 5: 00 a. m. Light rain remained over parts of East and South Alabama near daybreak, with the expectation that it will move out soon. The near-term pattern shifts quickly: the day turns breezy and cooler as skies clear, and North Alabama is not expected to climb out of the 50s this afternoon even with sunshine returning.
Overnight, the setup turns more favorable for cold conditions: skies are expected to be clear and temperatures will fall. By early tomorrow morning, readings are projected to drop into the 30s over the northern third of Alabama, where scattered frost is possible. Farther south, temperatures are expected to bottom out in the 40s. This is the first step in a larger temperature swing that culminates early next week.
What If a warming stretch arrives before the next front?
After the clear and cold night, the forecast turns brighter and warmer for a brief window. Tomorrow and Saturday are expected to feature abundant sunshine and a warming trend. High temperatures tomorrow are forecast in the 65–75 degree range, with Saturday afternoon highs projected between 73 and 83 degrees.
Sunday is expected to remain partly sunny and warm, with moisture beginning to increase. Even so, only isolated afternoon showers are anticipated and most of the state is expected to stay dry. High temperatures on Sunday are projected to run in the 70s and 80s. The key point for readers tracking a potential freeze warning scenario is that this warming stretch does not last long; it is followed by a sharp shift as the next system arrives late Sunday night into Monday morning.
What Happens When the sharp cold front arrives and a late-season freeze follows?
Next week’s turning point is tied to a sharp cold front expected to bring rain into Alabama after midnight Sunday night into Monday morning. Moisture is expected to be limited with this system, and projected rain amounts should be a quarter inch or less for most locations. After the rain Monday morning, the forecast calls for the rest of the week to be rain-free.
Behind the front, much colder air is expected to spill in. High temperatures are forecast to sit in the upper 40s across the Tennessee Valley on both Monday and Tuesday. The coldest signal arrives early Tuesday: a late-season freeze is likely for the northern two-thirds of the state Tuesday morning, with low temperatures projected between 24 and 34 degrees. Another freeze is also likely early Wednesday across North Alabama.
These conditions are why freeze warning attention is sharpening in the northern part of the state, even after a warm weekend feel. The forecast then turns back toward moderation: a warming trend begins Wednesday afternoon, and highs are expected to return to the 70s by Friday.
