Indianapolis, IN – Central Indiana residents can expect a warm-up and wet weather this week after a quiet, cool start to the weekend. High pressure dominating the region today will keep skies partly to mostly cloudy with seasonal highs in the 30s, but spring-like warmth is set to arrive starting Monday, signaling an unusual early January shift.
Monday Brings Early Week Warmth
A southwest flow returning to the Midwest and Ohio Valley will push an initial surge of warm air into Indiana on Monday. Highs are expected to reach the upper 40s, with a few areas potentially hitting 50°, marking a significant jump above average for January. Winds will be a touch breezy, though otherwise the day will remain largely dry.
Cloudy skies will dominate most of the week, except for Monday and Wednesday, typical of January’s gray conditions. Despite the clouds, temperatures will feel much milder than usual, giving residents a brief preview of what spring might bring.
Midweek Warmth: Highs in the 50s
Temperatures will continue to climb throughout the week. Forecasters predict:
- Tuesday: Highs in the 50s, slight chance of a stray northern shower
- Wednesday: Highs in the 50s, partly breezy
- Thursday: Upper 50s, increasing humidity and warmer conditions
For early January, these temperatures are well above average, with a stretch of several days in the 50°+ range not typically seen until later in the season.
Late Week Rain and Possible Thunderstorms
The main weather story will arrive Thursday into Friday, when a system moves into the region. Expect rain, potentially heavy at times, with isolated thunderstorms possible. While the exact timing and track of the system remain under review, forecasters caution that central Indiana could see a soggy, spring-like end to the work week, bringing both wet roads and elevated humidity.
Meteorologists are tracking rainfall totals carefully as forecast models are still being fine-tuned, but residents should plan for wet conditions and possible travel impacts heading into the weekend.
Historic Comparisons and Forecast Outlook
January typically sees an average of five days with highs above 50°, but this week alone could feature at least four such days, potentially marking the warmest stretch of January since 2023. For historical context, January 1880 recorded 22 days above 50°, the most on record. While this week won’t approach those numbers, the extended warmth is unusual for early January.
Forecasters remind residents that, despite the warmth, January weather remains unpredictable, and temperatures can drop quickly at night. Expect seasonal lows in the 30s even during this warm-up.
