Hartford is getting a foggy start Thursday, but the gray patch should burn off before a sunny and unusually mild afternoon. Temperatures will climb from the upper 30s early in the morning to about 69 degrees, giving the city one more warm fall day before a cooler Halloween weekend.

Patchy fog is expected to linger until around 9 a.m., followed by mostly sunny skies and south winds of 2 to 12 mph. The National Weather Service is forecasting no rain Thursday, with partly cloudy skies and a low near 51 Thursday night.

Friday Turns Gusty Before Halloween

Friday will stay sunny with a high in the mid-60s, but the breeze will be a bigger factor as west winds pick up through the day. Gusts could reach about 29 mph, so lightweight decorations, patio umbrellas and anything else not firmly secured may have a brief appointment with the Connecticut River.

Friday night will be mostly clear but much colder, with temperatures dropping to around 38 and northwest gusts reaching about 25 mph. Saturday, October 31, should bring sunny skies and a high near 60, followed by a chilly low near 42 for Halloween night.

Mostly Dry Into Early November

Sunday will be mostly cloudy and milder, with a high near 64 and light winds. Monday should remain partly sunny and reach about 66, keeping outdoor plans comfortable once the morning chill fades.

A slight chance of showers is forecast Tuesday into Wednesday. Wednesday remains partly sunny with a high near 66, according to the latest forecast.

The outlook is a substantive update from Wednesday's Hoodline forecast, which had called for a slightly warmer Friday and a less sharply defined early-week rain threat. For now, Hartford's best stretch for outdoor plans runs from Thursday afternoon through Monday, with the main nuisances being Thursday morning fog, Friday wind and Saturday night's early-season chill.
