Forecast: Sunny Today, Muggy With Possible Thunderstorms Tuesday

You might have thought Sunday was too cool for the first half of August, and indeed, temperatures averaged below what’s typica forl Aug. 9 by around 10 degrees. The lack of humidity along with the lack of heat, however, made for a very pleasant working day outside.

Today features more in the way of sunshine as high pressure remains in control of the weather. Temperatures won’t be as cool, reaching into the 70s to near 80 by 2 p.m. This is seasonably warm. I do expect even warmer readings to show up later this week, after some much needed rainfall.

On Tuesday, a kink in the jet stream will funnel moist and humid air northward and eastward into New England. I expect clouds to dominate all day, and if you are in vacation mode, this is the day this week to plan on taking in a summer movie, doing some shopping or perhaps just staying in bed late.

If you are in work mode, plan on some additional traffic headaches perhaps as early as the morning commute west of Boston as showers move into the region. The showers could be heavy at times and may be accompanied by a thunderstorm with torrential downpours. Throughout Tuesday, I’ll be updating the progress of the rain on Twitter @growingwisdom.

Once the system passes the area Tuesday night, skies will partially clear. It will be somewhat muggy and the humidity will stay high Wednesday morning before falling somewhat during the afternoon and evening. If you use your air conditioner Tuesday for the humidity, you might be able to get away with it off Wednesday night.

The rest of the week looks dry and warm with a moderate amount of humidity, but the air won’t feel oppressive. All in all, it’s a nice week to be off.

Today: Mostly sunny, with a high near 80.

Tonight: Partly cloudy, with a low 61-65.

Tuesday: Muggy with clouds and showers. Some thunderstorms are possible. Highs in the mid 70s.

Wednesday: A blend of clouds and sunshine. A brief midday shower possible. Highs in the lower 80s.

Thursday: Mostly sunny, with a high near 80-84.

Friday: Sunny, with a high near 85.
