Today's high and tonight's low, tracked live Tested
The dashed line is the forecast we issued before each high or low window began, kept fixed so you can see how the day compares with it. Once the window starts, the high or low is adjusted for how warm or cool the day is running against that line. Tested on a past year, by 3 PM this cut the typical miss on the day's high from 1.6° to 0.6°, and by 3 AM the miss on the night's low from 1.7° to 1.0°. The ± is the range that held 8 times in 10 at that hour.
The next 24 hours every 3 hours
Temperature follows our forecast where we have it, the model blend elsewhere. Sky and wind are the model blend. "Rain in runs" is the share of about 120 ensemble model runs showing rain in those 3 hours. It runs higher than what reaches the station's gauge, so the rain chance on the cards above, calibrated against the gauge, is the one to plan by.
The week ahead
Over the next week, highs range from 68° on Monday to 71° on Wednesday. No period looks likely to be wet; the best chance is Saturday night, at 13%.

Each bar runs from the night's low to the day's high; the faint band behind it is our 80% range. Rain is the higher of the day and night chances. Frost is shown when its chance is 30% or more.
Around us right now airports
The automated airports within 45 miles (Marion, Kokomo, Grissom, Huntington, Logansport, Rochester, Fort Wayne, Muncie, Anderson, Warsaw), read every 15 minutes and weighted toward Somerset by distance. "Upwind" compares the airports the wind is blowing from with our own station: air on its way here.
