Bostonians, brace yourselves for a mixed bag of weather in the coming days, as the forecast hints at comfortable afternoons, potential showers, and the effects of a distant hurricane stirring the coastal waters.

According to the National Weather Service, today will see partially sunny skies with highs around a pleasant 73 degrees. However, keep a light jacket close by, as clouds are set to increase with east winds picking up throughout the morning. Tonight's forecast predicts mostly cloudy conditions, and mild temperatures holding near 60 degrees. Come Wednesday, Boston could see some showers, particularly in the afternoon, with overcast skies and highs near 72. The chance of rain isn't set in stone, sitting at 30% but bring an umbrella along if you're out and about.

The latter half of the week is looking up – literally, toward clearer skies. A slight chance of rain lingers on Thursday morning, yet sunshine is on the forecast's horizon with a high again near 73 degrees. As the workweek wraps, Friday promises to greet us with sunny warmth, and temperatures are expected to rise to a comfortable 77.

Eyeing the weekend, the clear skies seem to hold steady, offering up an ideal backdrop for any outdoor endeavors. Saturday and Sunday temperatures will climb into the 80s, heralding what appears to be a slice of late summer generosity. However, while Erin, now a Category 3 hurricane, churns to our south – it could churn up life-threatening surf and rip currents. According to a report by Boston 25 News, advisories have been issued for the South Coast including Cape Cod and the Islands, with surf advisory extending through Thursday evening.
