Boston Weather: 83.0°F | Partly Cloudy

Weather: The Heat is Gone

By Michael J. Ring
STAFF METEOROLOGIST -- After the summerlike weather of late last week, today’s forecast brings a return to reality with more seasonable temperatures and the threat of showers several days this week.

The meteorological conditions over the past few days have been a stark contrast at the different ends of the North American continent, thanks to different systems in the West and East. A weak ridge over the Southwest brought unseasonably warm temperatures west of the Rockies as the jet stream has been pushed northward toward Canada. Over the eastern half of the continent, however, the jet stream plunged southward, carrying with it the cooler temperatures seen in the East over the past few days.

As the trough and an associated front both slide eastward today we should see some clearing; however temperatures will remain seasonable throughout the week. Nor will the weather remain dry for the next few days -- weak weather systems moving through on Wednesday and Thursday mean each day features the threat of showers.
