Weekly Outlook: August 12-18, 2019

After a pretty- good weekend weatherwise, we’ve got another decent day today, though humidity levels will start to creep up. After that, there’s some rain in our future.

High pressure remains in control today, but it will be offshore, so we’ll see moisture start to move into the region. You’ll notice it both at the surface, where dewpoints will start to creep up, and later of aloft, as some clouds start to move into the region. A few showers are possible Monday night as a cold front starts to approach the region, but the bulk of the activity will wait until Tuesday when the front moves through. Some thunderstorms are also possible, especially towards the South Coast where there is the potential for some heavy downpours.

The front pushes offshore Tuesday night then stalls south of New England while high pressure tries to build in to the north. As a result, we may have clouds lingering near the south coast while sunshine dominates farther north.

Another weak disturbance will move through on Thursday with some additional clouds and possibly a few more showers, then high pressure builds in for Friday and the weekend with conditions fairly similar to what we just had this past weekend. This also includes the chance for a few widely scattered pop-up showers. These won’t be an issue for 90-95% of the region, but if you’re one of the unlucky 5-10%, they won’t last too long and shouldn’t be that heavy. Certainly nothing to cancel any plans over.

While we’re talking about next weekend, we just wanted to let you know that next week’s outlook will likely be posted at some point next Sunday morning, and not early Monday morning as usual. We’ll return to the Monday morning posting the following week.

Monday: Morning sunshine starts to fade behind increasing high clouds in the afternoon, becoming humid. High 80-87.

Monday night: Becoming mostly cloudy with a few showers possible, especially across southern New Hampshire and northern Massachusetts. Low 64-71.

Wednesday: Partly to mostly sunny from the Merrimack Valley northward, intervals of clouds and sunshine elsewhere. High 73-80, coolest along the coast.

Thursday: A mix of sun and clouds, chance for a shower or two. High 72-79.
