Bostonians, brace yourselves for a mixed bag of weather ahead. Today's forecast predicts a chance of showers and thunderstorms, particularly after noon, with mostly cloudy skies and a high temperature hovering around 87 degrees. Winds are set to shift from southwest to east in the afternoon, and while there's a 50 percent chance of precipitation, rainfall amounts are expected to be moderate, save for potential higher quantities during thunderstorms, as per National Weather Service's report.

Tonight, the weather will take a turn for the better, with skies clearing up and lows dropping to around 69 degrees. According to NBC Boston, "Storms will likely diminish later tonight," providing some respite from what seems like a week of relentless humidity and unpredictable downpours. The week has indeed been eventful with a range of weather extremes, from scorching heat to sudden flash flooding.

Looking forward, the weekend promises more favorable conditions. Friday's forecast offers sunny skies with high temperatures in the mid to upper 70s and a pleasant east wind, giving Bostonians a break from the muggier air. Saturday will sustain this comfort, with continued sunshine and lower humidity, as daytime highs are expected to reach the low 80s.

Enjoy the reprieve while it lasts because Sunday marks the return of the heat with temperatures set to rise near the 90-degree mark. However, a cold front is anticipated to bring cooler weather as the new week begins, according to both the National Weather Service and NBC Boston. "Temperatures will heat back up to near 90 degrees by Sunday," NBC Boston reported, preempting another bout of high heat before the front's intervention.

In the midst of local weather developments, a bigger picture looms with Tropical Storm Erin gaining strength over the Atlantic. Although the storm poses no immediate threat to land, NBC Boston advises vigilance as Erin is on course to become a major hurricane by the weekend and its trajectory could still alter.
