I admit I enjoy the heat in general (a sure sign I'm not a Mainer originally...well, that and the super tight suits and tolerance for traffic) ; but yesterday was a bit much. Most of southern and western Maine hit at least 95 F and humidity was hovering somewhere between "oppressive" and "Honestly-I'm-Not-Really-A-Sweaty-Person!"

Humidity will remain high today, but the bigger story will be the possibility for severe thunderstorms this afternoon.

Today: Hazy, hot and humid through the first part of the day with a mixture of sun and clouds. However, showers and thunderstorms are already developing in New Hampshire and far western Maine. These showers and storms are running out ahead of an approaching cold front that will arrive later this afternoon. In short; the atmosphere looks pretty ripe for severe thunderstorms today. The thunderstorm activity will pick up in earnest by 1 PM with storm cells popping up left and right. My largest concern for these storms is the possibility of damaging straight line winds and some large hail. We will keep you up to date as the individual storms develop. High temperatures will end up in the upper 80s to low 90s in most spots, despite the relatively brief sunshine.

Tonight: An early thunderstorm is possible but the activity should clear Downeast by 9 PM. After that look for rapid clearing with winds shift to the northwest. We will start out very humid but gradually dry out by the early morning hours.

Sunday: Ahhhh so fresh and so clean, clean. Behind the cold front a Canadian high pressure system will build down and provide much cooler and drier air for Sunday. Dew points will drop into the 50s and even 40s on a strong northwest wind. The result will be a pleasant and sunny day with highs around 78-80. Awesome day.

Monday will be similar to Sunday with high pressure still in place. Mostly sunny skies will prevail and dew points will remain very comfortable. Highs in the low 80s will be common.

A chance of showers returns to the forecast for Tuesday afternoon through Wednesday, but it doesn't look like anything too heavy.

Overall we will snap back into a cooler patter in the 5-7 day range with no big heat waves in the forecast.
