Indianapolis woke Sunday, October 18, to clear skies, temperatures in the upper 30s and a quick reminder that fall is not playing around. A Frost Advisory remains in effect until 9 a.m., followed by bright sunshine and an afternoon high near 64 degrees.
Residents with tender outdoor plants should cover them before the advisory ends, since frost could damage sensitive vegetation. After the chilly start, south-southeast winds will stay light at 2 to 6 mph, with no rain in the forecast.
Sunny Warmup Arrives This Week
The temperature rebound begins Monday, October 19, with sunny skies and a high near 68 degrees. Tuesday should reach 71, followed by highs around 72 Wednesday and 73 Thursday, according to the National Weather Service.
The forecast stays dry and mostly sunny through Saturday, October 24, with afternoon temperatures holding near the low 70s. It is a sizable turnaround from Sunday morning's frost risk, although the nights will remain cool, dropping to the upper 30s Sunday night and then gradually warming through the 40s.
Cool Mornings, Comfortable Afternoons
Sunday night will be clear with a low around 38 degrees, while Monday night falls near 40. Overnight lows rise to about 43 Tuesday, 45 Wednesday and the upper 40s later in the week, so early risers will still want a jacket even as afternoons turn pleasantly mild.
For Indianapolis residents planning outdoor errands or activities, the best window Sunday comes after the morning frost lifts. After that, the week offers plenty of sunshine and unusually warm October afternoons, with little weather drama on the horizon.
