Bostonians may want to keep an umbrella close at hand as sporadic showers and thunderstorms are predicted to dot the week ahead. The National Weather Service cautions a 40% chance of precipitation Monday with possible showers and thunderstorms breaking through in the afternoon, adding drips and drabs to the holiday mood. Clouds will command the sky with the occasional rumble, as winds take a turn from the east, nudging the thermometer to a comfortable 70 degrees.

Into Monday night, the city gets a 100% guarantee of wetness, with showers likely escalating to a thunderstorm, showers may challenge outdoor plans for Memorial Day and beyond, with new rainfall amounting up to half an inch in some areas. The warmth isn't backing down, though; Tuesday could press temps as high as 81 degrees despite a 50% shot of thunderstorms.

Clear skies make a fleeting comeback Tuesday night, but don't stow the rain boots yet. The week's weather narrative holds on to a repetitive beat with the potential for showers returning Wednesday afternoon, affecting a mostly sunny day, with a high near 79 degrees, according to forecast.weather.gov.

According to a report by NBC Boston, the following days mellow with a cooler ambience, mainly dry, though Thursday could bring more showers before noon, and the skies will clear up towards the end of the week with mostly sunny conditions prevailing by Friday. Boston's notorious fickle weather is living up to its reputation this week, as temperatures dance across the spectrum while the city flirts with the possibility of a thunderstorm popping up here and there.
