Boston Weather: 38.0°F | A Few Clouds and Windy

Weather: Fall Around the Corner

By VÉronique Bugnion
STAFF METEOROLOGIST --

The ridge of high pressure which allowed us to deny that fall was just around the corner is slowly weakening and drifting towards Nova Scotia. Meanwhile, the jet stream is making a major excursion from its usual West to East track and is dipping as far South as Texas. The upper-level disturbance associated with this movement of air masses will influence our weather later this week. A surface low pressure center will develop at the core of this trough but will remain in Canada. On Wednesday in Boston, the cold front extending along the leading edge of this disturbance will bring us numerous clouds. Rain and possibly strong South-Westerly winds are in store for Thursday. This may yet again increase the rainfall total for the month of September, currently at 11.18 inches. The old record of 11.04 inches set back in 1933 has already been broken.

We will only briefly be exposed to colder air on Friday before returning to normal temperatures over the weekend.
