Boston is gearing up for a diverse range of weather conditions as the weekend progresses into early next week. According to a forecast from the National Weather Service, today Bostonians can expect mostly sunny skies with highs peaking near 76 degrees. The calm northwest winds in the morning are set to shift east in the afternoon. However, tonight's forecast suggests a slight chance of showers after 2am with mostly cloudy conditions and a low around 63 degrees.

Transitioning into Sunday, after the possibility of overnight showers, the city will see mostly cloudy skies in the morning becoming sunny by the afternoon with a high near 81 degrees, as reported by Boston 25 News. While clouds will be increasing through the evening tonight, the rainfall should taper off before sunrise on Sunday, setting the stage for a brighter, warmer end to the weekend.

As Monday rolls in, residents can enjoy sunny skies with daytime temperatures hovering near 77 degrees. But a cooler trend is on the horizon, with a noticeable shift starting midweek. Come Wednesday, the high is expected to plummet to the low 60s, signaling an early taste of October as mornings grow chilly, dipping into the 30s and 40s.

In addition to concerning the daily forecasts, attention is drawn to the tropics, where Hurricane Humberto, currently a Category 4 storm, brandishes winds nearing 125 mph according to Boston 25 News. While weakening is forecasted next week as the storm tracks north and becomes extratropical, the impact on New England will be limited to dangerous surf and rip currents through early next week.

Elsewhere, the formation of Potential Tropical Cyclone Nine is being monitored near the Bahamas, expected to strengthen into a tropical storm, with a chance of achieving hurricane status by Monday. This system poses a threat to cause coastal flooding, winds, and heavy rain from Florida to the Carolinas, though it's too early to determine if a U.S. landfall will occur.
