A hazy start to the day will result in a hot, humid, and hazy finish. Humidity levels (in terms of the dew point temperature) rose about 10° from Tuesday to Wednesday as warmer, humid air moved in from the Mid-Atlantic and Midwest U.S.
A Heat Advisory is in effect for Wednesday afternoon, more specifically 12 p.m. - 8 p.m. This is for the Champlain Valley and St. Lawrence Valley (Montreal) where temperatures will get the hottest. The temperature, combined with the humidly level will create a heat index (or what it feels like to the skin) of about 100° in the afternoon!
We here at the SkyTracker weather center have been consistently forecasting 90s for Wednesday/Thursday since late last week. The numbers continue to look like this:
These numbers are for Wednesday, June 20. Thursday will be just as hot, if not, one or two degrees hotter. I do believe we'll have another Heat Advisory issued by the National Weather Service for the area Thursday.
The heat isn't totally unusual for this time of year, although it is still very hot. The average high this time of year in Burlington is 78°. However the records are close to the forecast high, so it is a once-in-a-while instance.

The air quality is going to be tough today and tomorrow. There are no Air Quality Alerts out at the moment from the National Weather Service, but dew point levels will be in the 60s and close to 70° at some point in the day which will make the air feel very uncomfortable. As the Heat Advisory points to, it will make things dangerous in some situations as well. Heavy outdoor exercising in the sunlight during the afternoon hours is strongly discouraged. Be sure to keep up on the clear liquids (of course water!) avoid the sunlight, stay inside if you can, and don't leave pets or children in the cars!
