Hartford is waking Tuesday to clear skies, cool air and a brisk northwest breeze, with temperatures in the 40s early and a high near 59 degrees. The bigger weather story arrives after sunset, when temperatures could drop into the 30s and frost threatens sensitive plants across the region.
Frost Advisory Covers Tuesday Night
The National Weather Service has issued a Frost Advisory from 11 p.m. Tuesday through 9 a.m. Wednesday, with temperatures expected to reach 33 to 36 degrees in the coldest spots. Residents with flowers, herbs or other tender outdoor plants should cover them or bring them inside before the cold settles in, according to the National Weather Service.
Tuesday afternoon will stay sunny, though northwest winds of 8 to 12 mph may make it feel cooler than the thermometer suggests. Winds should ease overnight, setting up the clear, chilly conditions that allow frost to form.
Warm-Up Arrives By Thursday
Wednesday brings a quick rebound, with sunshine and a high near 65 degrees, although south winds could gust as high as 22 mph. Thursday's high will be near 67 degrees.
The sharp overnight chill is a notable update from the earlier week-ahead outlook, which had already pointed toward a cooler turn. The latest forecast now includes a specific frost threat for Hartford-area gardeners and anyone with outdoor plants, as detailed in an earlier Hoodline forecast.
Mostly Dry Through The Weekend
Friday and Saturday should remain sunny and seasonable. Sunday is expected to bring sunshine and a few clouds, while rain remains possible late in the weekend.
Columbus Day on Monday could bring sunshine, a few clouds and early showers. For now, the forecast favors a mostly dry week, with the coldest night arriving before the temperatures climb again.
