There will be two parts to today’s weather. The first is already underway across the region and will feature variable clouds, warm temps, and slowly but surely increasing humidity. Highs will warm into the 80’s for most with some upper 70’s along the coast. All in all, most of the day will be absolutely lovely, albeit a bit sticky. The second part of the day will begin in the late afternoon over Western NH and slowly move E into Maine by late evening. This will be the showers and thunderstorms section of today’s weather. The ingredients are not here for big severe storms, but there is plenty of moisture in the air and a period of wet weather is expected, possibly with a few rumbles. The best chance for a thunderstorm will be over western NH where a few strong wind gusts are possible. Otherwise, most areas just see showers.
Here’s a bit of a visual on how I think things play out this evening. A band of showers will likely impact everyone with light to moderate rain. Within that band, there will likely be pockets of heavier rain that not everyone sees. There are also likely to be a few rumbles of thunder especially over Western areas. Strong storms from NY and VT could hold on to produce a few strong wind gusts in Western NH but overall no severe weather is expected. Thunderstorms will enter NH late this afternoon between 2 and 4 PM before moving east and weakening into a band of showers that will move into Maine in the evening between 5 and 7 PM. The map shown is valid at 8 PM but is not intended to pinpoint details. I just wanted to give a sense of what the situation might look like come evening. Rain will move out early in the overnight hours and tomorrow looks like another lovely summer day.
