Fishers residents with tender plants still outdoors may want to cover them tonight.
The National Weather Service in Indianapolis has issued a frost advisory for much of central Indiana, including Hamilton County, from 2 a.m. to 9 a.m. Monday. Forecasters say temperatures could dip as low as 35 degrees, cold enough for frost to form on grass, rooftops, car windshields and exposed vegetation.
The advisory also covers portions of east central, north central, south central, southeast, southwest and west central Indiana.
According to the weather service, frost could damage sensitive outdoor vegetation, and plants left uncovered may be killed.
Tonight is expected to be clear with a low around 36 and a light southeast wind. Clear skies and light winds are the classic recipe for frost because heat escapes quickly from the ground overnight, allowing frost to form even when the official air temperature stays a few degrees above freezing.
Protecting your plants
Gardeners can take a few simple steps before heading to bed Sunday night:
- Bring potted plants, hanging baskets and herbs indoors or into a garage.
- Cover in-ground plants with old sheets, blankets or burlap, letting the fabric reach the ground to trap warmth. Avoid letting plastic touch the leaves directly.
- Harvest any remaining tomatoes, peppers, basil and other cold-sensitive produce.
- Remove coverings Monday morning once temperatures rise.
Hardy fall favorites such as mums, pansies, kale and ornamental cabbage typically handle a light frost without trouble.
Monday morning commute
Drivers should allow a few extra minutes Monday to scrape frosty windshields. P
Warm, dry week ahead
The chill will not last long. Monday is forecast to be sunny with a high near 68 and calm winds, and temperatures will climb into the low 70s by midweek.
The forecast calls for sunshine every day through Saturday:
- Monday: Patchy frost early, then sunny, high near 68. Low around 38.
- Tuesday: Sunny, high near 70. Low around 42.
- Wednesday: Sunny, high near 71. Low around 43.
- Thursday: Sunny, high near 71. Low around 46.
- Friday: Sunny, high near 69. Low around 44.
- Saturday: Sunny, high near 69.
The stretch of dry, mild weather should be good news for fall yard work and weekend outdoor events across Fishers.
Frost advisories are a regular part of the season in central Indiana as fall settles in. Once a hard, widespread freeze ends the growing season, the weather service typically stops issuing frost advisories for the area until spring.
