Storm Prediction Center in an unsettled week: Alabama waits between calm Tuesday and possible Wednesday night storms
Just after the First Alert Weather Day ended in Alabama, the night stayed noisy enough that some people could still hear rumbles outside, as scattered storms and pockets of locally heavy rain lingered. In that in-between moment—when rain tapers but certainty doesn’t—many residents turn their attention to the storm prediction center mindset: watching the next window, checking timing, and weighing what “possible” could mean by Wednesday night.
What is changing between Tuesday and Wednesday night?
Tuesday is expected to be the breather. Conditions are described as much calmer, with a mostly cloudy sky and only a slight chance of isolated showers in parts of the area. In Birmingham, the chance for isolated showers is described as 20%, with highs in the 80s. In Central and South Alabama, Tuesday is framed as the best day for outdoor plans, with only a slight chance of showers mainly across northern portions of the area and highs climbing into the low 80s.
By Wednesday, the tone shifts back to watchful. Wednesday is expected to start off dry, warm, and muggy, before a chance for heavier rain and storms arrives late Wednesday night. Central and South Alabama are described as staying locked into a warm, wet pattern that persists through Wednesday, with showers and thunderstorms developing and becoming more numerous through the afternoon and evening.
How serious could the midweek storms become?
The midweek system carries the week’s clearest warning language. From late Wednesday night through Thursday morning, forecasters are continuing to highlight the potential for heavier rain, strong straight-line wind gusts, and hail. In Central and South Alabama, the main threats mentioned include damaging wind gusts and large hail, with a note that some storms could become strong to severe.
There is also mention of tornado potential during the stronger system expected to move into Central and South Alabama: a line of storms is expected to develop and move across the region, bringing heavy rain, frequent lightning, strong winds, and the potential for a few tornadoes. The tornado risk is described as low at this time, but not zero.
At the same time, not every signal is trending worse. Recent model runs have backed off considerably on instability, which is described as an encouraging trend, even while the First Alert Weather Day remains highlighted for the late Wednesday night into Thursday morning period.
What comes after the storms: a brief cool-down, then more swings
Behind the Wednesday night into Thursday morning system, the pattern is expected to change quickly. In the Birmingham area, a sharp cool-down is expected, with lows dropping into the upper 30s and lower 40s by Friday morning. In Central and South Alabama, a strong cold front is expected to move through Wednesday night into Thursday morning, bringing a temporary shift: Thursday starts with a chance of showers early before conditions gradually improve, and highs only reach the low 60s—described as a noticeable drop from the mid-80s expected on Wednesday.
The cool-down does not last long. Conditions are expected to clear out Friday with sunny skies and highs in the low 70s, followed by a warming trend into the weekend with highs climbing back into the upper 70s. Beyond that, the broader message is continued variability as winter closes out: temperatures are expected to rebound to above-normal levels by the weekend before dropping again early next week, while an unsettled pattern continues.
Forecast discussions also point to another possible turn later: there are signs of another surge of even colder air around St. Patrick’s Day, with the next system potentially bringing another round of heavier rain and storms Sunday night into Monday, followed by the potential for freezing temperatures. With that kind of swing, the storm prediction center approach—treating calm periods as preparation time—remains the practical posture for many households.
