Maine Supercells Loom with EF2 Tornado, 70 MPH Wind Threats — SevereWX

Storms are firing up across western Maine this afternoon, where mid-70s temperatures and mid-60s dewpoints are fueling a surge in coverage and intensity. The Storm Prediction Center highlights 35-40 knots of shear supporting storm organization, including supercell structures.

While instability remains relatively weak—which tempers expectations for widespread severity—a few robust storms could still deliver serious hazards. SPC pegs peak threats at:

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

This setup prompts a Mesoscale Discussion (1708) with a 40% chance of a severe thunderstorm watch through around 2:45 PM EDT. Activity should peak amid continued daytime heating.

The affected area spans a large swath of Maine, from roughly the western border eastward. Keep an eye on SPC's mesoanalysis and regional radars for updates.

Stay prepared: Monitor local warnings via NOAA Weather Radio or apps, secure outdoor items, and have a severe weather plan ready. If storms approach, seek shelter in an interior room away from windows.
