Maine Afternoon Storms Poised for Supercell Surge, Watch in Play — SevereWX

Storms are firing up across western Maine amid mid-70s temperatures and mid-60s dewpoints, setting the stage for broader coverage and intensification through the afternoon.

SPC's Mesoscale Discussion 1708 highlights 35-40 knots of shear supporting storm organization, including supercell potential. While instability remains on the weaker side, any severe development could prompt a thunderstorm watch—rated at 40% odds.

Peak threats include:

• Tornadoes: Up to 90 mph (EF2 intensity)
• Winds: 55-70 mph gusts
• Hail: Up to 1.25 inches

Activity should ramp up ahead of initial clusters, focusing on a large swath of the state through late afternoon (valid until 221845Z).

This comes as recent severe weather shifts eastward, with Maine now in the spotlight for isolated but potent storms. Monitor radar closely as heating peaks.

Stay prepared: Review your severe weather plan, ensure mobile alerts are on, and seek shelter if warnings issue. Check SPC.noaa.gov and local NWS for updates.
