The unusual part of the forecast comes before sunrise
Columbus residents looking for the clearest sign of this week’s unusual weather will find it in the morning readings rather than the afternoon forecast. Overnight temperatures have been running about 8 to 16 degrees above normal for late October, even as daytime highs remain generally close to seasonal levels.
The official observations from Columbus Airport show the contrast. Thursday’s high reached 80 degrees, compared with a normal high of 74 for the date. That reading was warmer than average but not exceptional. The morning low, however, was 59 degrees, while the usual low at this point in October is 51 degrees.
Forecasters with the National Weather Service office in Peachtree City expect that pattern to continue through the next seven days across west Georgia and east Alabama. Afternoon temperatures are projected to remain near their typical range, while nighttime readings stay noticeably milder than the calendar would suggest.
Cloud cover is limiting the overnight cooldown
Clear skies normally allow the ground to release heat after sunset, causing temperatures to fall steadily toward dawn. This week, a layer of middle- and upper-level clouds moving in from the west is interrupting that process. The cloud cover is helping retain some of the heat near the surface and sending part of it back toward the ground.
That effect is reflected in Columbus’ forecast lows. The expected overnight readings are 62 degrees, followed by 60 Saturday night and 57 Sunday night. Each would remain above the late-October normal of 51 degrees.
- Thursday morning low: 59 degrees
- Normal late-October low: 51 degrees
- Forecast low Friday night: 62 degrees
- Forecast low Saturday night: 60 degrees
- Forecast low Sunday night: 57 degrees
Warm, but not close to Columbus records
The current spell is not approaching the city’s October temperature extremes. Records covering 78 years show that the warmest reading for Oct. 30 in Columbus was 90 degrees in 1984. The coldest was 24 degrees in 1952. A forecast high near 81 remains well below the warmest mark and far above the coldest.
That distinction matters because the week’s warmth is most apparent when compared with normal values, particularly during the hours before daylight. The available forecast does not point to record heat; instead, it describes a sustained run of warmer-than-usual mornings beneath partly or mostly cloudy conditions.
Columbus has also had a wetter-than-normal year
The temperature pattern comes as Columbus’ precipitation totals remain ahead of average. Since Jan. 1, the city has received 43.64 inches of rain, compared with a normal total of 40.06 inches by this date. October also finished wetter than typical through Oct. 29, with 3.30 inches recorded against a normal of 2.61 inches.
| Measure | Columbus total | Normal |
|---|---|---|
| Rain since Jan. 1 | 43.64 inches | 40.06 inches |
| October rainfall through Oct. 29 | 3.30 inches | 2.61 inches |
Showers and storms may bring a sharper change
Forecasters expect showers and thunderstorms to become more likely Wednesday. The following Thursday morning could bring the first noticeably cooler start of this stretch, with a projected low of 52 degrees in Columbus. That would place the overnight temperature much closer to the level normally expected for the end of October.
Until then, the main weather story remains the persistence of mild nights rather than extreme daytime heat. Cloud cover is helping Columbus hold onto warmth after sunset, while the city’s rainfall ledger continues to run above normal. The expected midweek rain and the cooler reading afterward could mark the transition back toward more typical late-October conditions.
