Weekend Outlook

Hello everyone!

I’m headed back offline this weekend so this post will contain forecast information to get you through until I’m back on Monday morning.

Tomorrow looks to be the nicer day of the weekend with sunny skies in the morning giving way to a few clouds in the afternoon. High pressure will be passing right overhead so clouds will be of the afternoon pop-up variety and are unlikely to drop more than a brief shower over the mountains and southern foothills. High temps will range through the mid/upper 70s for most with a sea breeze holding temps down along the coast.

Unsettled weather will return (again) on Sunday as low pressure moves up the Saint Lawrence Valley. Expect showers to be ongoing across most of the area as the sun comes up with the steadiest rain found up in the mountains closer to the storm. Warmer air will try to move in behind these showers midday, with some breaks of sun possible in southern and western NH. Just how much sun we get will determine how strong a round of afternoon showers and storms can get as that low drags a cold front through. Right now, the best shot at some afternoon sunshine and evening thunderstorms looks to be southwestern NH but if you see some sunshine in the ME foothills, keep the possibility of some rumbles in the back of your mind.

Thick cloud cover and onshore southeasterly breezes will hold temps in the mid 60s along the Midcoast with upper 60s to around 70 more common in the foothills and points west of Portland. Some spots in SW NH may run into the mid 70s if the sun can come out, but that’s not a guarantee.

Showers and storms will fade around sunset before quieter weather returns to start the week.

I’ll be back again on Monday.

Another Round of Afternoon Showers and Storms Today

Hello everyone!

Today will feature another round of afternoon showers and thunderstorms as pockets of cooler air aloft continue to provide instability across the area. Skies will start off mostly sunny this morning before becoming mostly cloudy this afternoon as instability is generated by the contrast between warming air near the ground and cooling air aloft. Any one of these afternoon clouds will be capable of dropping some rain and gusty winds given the setup. The best chance for a severe storm (producing winds strong enough to maybe cause a power outage or two) will be in southern NH and far SW ME where more instability will be present. These storms shouldn’t last too long so if one drifts by your area, just duck inside for a few minutes to let it pass. Shower activity will fade around and after sunset as we lose daytime heating.

High temps will remain seasonably cool, ranging from the upper 60s up north to the upper 70s in southern NH.
