Boston Weather: 70.0°F | Partly Cloudy



Foliage Special

By Marek Zebrowski
staff meterologist

The cold and unstable flow of the past few days will turn more westerly and southerly, bringing fair and warmer weather for the end of this week. A surface high will slowly crest overhead on Friday and by Saturday we will be on the western, warmer side of this system. With clear conditions, dry airmass and a lower angle of the sun, a wide diurnal temperature range is to be expected: a touch of frost at sunrise (except on the immediate coast and in the city) will give way to pleasantly warm afternoons. A cold front should move through rather quickly on Sunday, ushering in colder, clear weather for Columbus Day and into midweek.

Today: Sunny and pleasant with light winds drifting into a seabreeze by midday. High 67F (19C).

Tonight: Clear and cool with lows around 48F (9C) in the city, and in the 30s to low 40s (0-5C) outside the metropolitan area.

Saturday: Mostly sunny and warmer with highs around 72F (22C), southwesterly winds 10-15 mph (16-24 kph).

Sunday: Cloudy with some showers. Highs in mid 60s (16-18C), lows in low 50s (10-12C). Clearing and colder with increasing northwesterly winds by evening.

Monday: Fair, windy and colder. Highs around 60F (15C), lows in low 40s (5-7C).
