Hartford is starting Sunday with temperatures near freezing and areas of frost, but the chilly opening act will give way to bright sunshine. The city is expected to reach about 57 degrees, making for a crisp morning and a much easier afternoon outdoors.

Frost should linger before 10 a.m., with light north winds around 3 mph and no rain in the forecast. The National Weather Service expects clear skies tonight, when temperatures fall back to around 36 degrees.

Another Frosty Start Before A Milder Monday

Monday morning could bring patchy frost before 8 a.m., followed by mostly sunny skies and a high near 61. Monday night turns mostly cloudy with a low around 43, but precipitation chances remain minimal across Hartford.

Breezier Midweek Weather Stays Mostly Dry

Tuesday should be partly sunny and warmer, with a high near 64 and north winds between 10 and 14 mph. Wednesday turns sunny but cooler, topping out near 58, while Thursday could see a slight shower chance before 8 a.m. before returning to mostly sunny conditions.

The broader outlook keeps Hartford mainly dry through Saturday, with highs generally in the upper 50s and low 60s. The updated forecast is a modest shift from Saturday's Hoodline forecast, nudging Sunday's high upward while extending the calm, sunny stretch into the workweek.
