Forecasters say the region's first frost is possible Friday and Saturday nights after a mild start to the week.
Updated on Nov. 12, 2026 in Forecasts
Mobile is forecast to cool sharply this weekend, with the region's first frost possible Friday and Saturday nights. Tonight stays mild in the upper 50s, and Thursday brings mostly sunny skies with highs in the mid 70s before colder air arrives Thursday night.
Why it matters
The shift marks the start of colder seasonal temperatures for the Mobile area, bringing a practical need to protect plants and prepare for freezing overnight lows. Residents should expect a dry weekend with no rain forecast before scattered showers return early next week.
Forecast overnight lows drop to 37 degrees along I-10 Friday night and to the mid to upper 30s near the coast Saturday night, with low 30s inland. Exact frost coverage and timing remain subject to change as the cold air mass develops.
The details
Tonight is forecast to be mild with partly cloudy skies and temperatures in the upper 50s. Thursday brings mostly sunny skies and highs in the mid 70s, followed by a drop into the 40s Thursday night as colder air arrives, with temperatures plummeting Friday and Saturday nights.
Timeline
Tonight (Wednesday night): Mild, partly cloudy, upper 50s.
Thursday: Mostly sunny with mid 70s highs.
Thursday night: Lows drop into the 40s as chilly air arrives.
Friday night: First frost possible, lows near 37 degrees along I-10.
Saturday night: Frost conditions, mid to upper 30s coast and low 30s inland.
Seasonal Patterns
The forecast first frost places Mobile at the leading edge of typical first-frost timing for the Gulf Coast region documented in NOAA climate normals. The cold snap follows a mild week, reflecting the normal seasonal transition into cooler autumn temperatures.
Residents should cover or bring in sensitive plants and pipes before Friday and Saturday nights when frost is possible. Check local forecasts again before the weekend, since the exact timing and coverage of frost may shift.
The takeaway
Protecting tender plants and exposed pipes before Friday night is the most practical step ahead of the first frost. Monitoring updated forecasts will help confirm whether the coldest overnight lows materialize as expected.
What happens next
Scattered showers are forecast for Monday as another system approaches the area, with conditions expected to moderate slightly early next week.
