Today will feature another day of hot and humid weather and afternoon thunderstorms, though today’s fireworks show looks a bit more widespread and intense as a cold front approaches from the north. Skies are partly to mostly sunny this morning and remnant cloud cover especially over the north should gradually subside over the next few hours. The strong sunshine and southwesterly breezes will push temps into the mid 80s up north and low to mid 90s down south, with marine influences once again limited to the islands of Penobscot Bay and the southern tips of Midcoast peninsulas.
By around noon, storms will begin to fire up in the mountains as the front approaches. Storms will then move towards the coast during the afternoon hours and could pack quite the punch given how much energy our hot and humid airmass will provide. All cells will produce dangerous lightning and heavy rain while many will also pack strong winds capable of producing power outages. A few folks might see some hail today, but the middle part of the atmosphere isn’t quite set up right for widespread big hail concerns. The lower part of the atmosphere is teetering on the edge of being favorable for tornadoes, and I wouldn’t be surprised to see a warning or two issued for someone in the Sebago Lake region. Make sure you have a way of receiving warning information in the event one is issued for your location.
Storms will sweep offshore this evening with another broken line of showers along a secondary boundary potentially moving into the mountains around sunset.
