Forecast: Storm Misses Boston Today; Mass. To Swelter In Likely Heat Wave Starting This Weekend

A storm this morning is passing east of the region and just clipping parts of Cape Cod with a few potential showers. This afternoon, another shower or two may pop up from the west as a separate and weak storm crosses the region.

Once each of these weather systems moves out of the picture the heat starts arriving on Saturday and then really takes off Sunday.

There is a chance many of you will see temperatures reach at least 90 degrees or even the mid-90s Sunday, Monday and Tuesday. This would be another heat wave, and the second heat wave this year. If that occurred, we won't know until later Tuesday, this would be the earliest two heat waves have ever been happened so soon in the season. Records go back to 1872 — so that would be a big deal.

If you are headed to northern New England it will be hottest on Sunday as well. Tomorrow there is the chance for showers or a thunderstorm, and the lakes region are most likely to see the rain.
