Maine Thunderstorms Gain Strength, Fueling Supercell and Watch Concerns — SevereWX

Storms are firing up across western Maine this afternoon, where mid-70s temperatures and mid-60s dewpoints are driving destabilization. As heating continues, expect broader storm coverage with 35-40 knots of shear helping storms organize—potentially into supercells.

SPC's Mesoscale Discussion 1708 highlights this setup, valid until around 2:45 PM EDT. While instability is on the weaker side, limiting severe coverage confidence, any storms that tap into it could pack serious punch: tornadoes up to 90 mph (EF2 intensity), wind gusts of 55-70 mph, and hail to 1.25 inches.

A severe thunderstorm watch carries 40% odds if threats materialize, covering much of the state. This comes amid ongoing Maine storm activity, but forecasters note the shear's role in boosting organization.

Key Threats:

• Tornadoes: Up to 90 mph
• Winds: 55-70 mph
• Hail: Up to 1.25 inches

Monitor radar closely, especially if you're in the affected area from western Maine eastward. Have your severe weather plan ready—know where to shelter, charge devices, and stay tuned to local NWS updates via www.weather.gov.

Stay safe out there.
