BOSTON (CBS) — You can cut the air with a knife! The humidity is back and our temps are set to skyrocket into the upper 80s and lower 90s. With the high humidity we expect our heat index values to be in the upper 90s. Definitely a pool or beach day! However, keep an eye to the sky because there is a slight risk for severe storms late this afternoon.

Forecast models are still in disagreement on the exact placement of the storms. Regardless, areas north and west of Boston will see some storms after 2 p.m. The question is. . . how far south does the energy expand?

Location

Sunshine will help to elevate our instability this afternoon. There is also a chance for the storms to organize into a larger complex, which could give us a higher impact event with widespread damaging wind. If that complex develops it could spread to areas south of the Mass Pike. We just have to see how the environment acts.

The hour-by-hour timing shows storms north of Boston by 3 p.m. These stay isolated in nature. More storms erupt in the evening and spread as far south as the Mass Pike by 8 p.m. The storms may impact Boston between 8 p.m. and 11 p.m. as they move southeast. Keep an eye on radar using our weather app if you will be out and about.

Damaging wind is the primary threat, along with large hail, flooding rain. Thunder and lightning will be possible with any storm that develops. A spin-up tornado can’t be ruled out either, but is not likely.
