Boston residents can expect a notable shift in weather, with the forecast predicting a medley of showers and thunderstorms punctuated by sunny intervals. The city will experience a high of 92 degrees today, with the potential for the heat index to climb as high as 100 before a "backdoor" cold front sweeps through on Wednesday, causing temperatures to plunge by 15 to 20 degrees, according to National Weather Service.

As reported by NBC Boston, it's not just the sweltering heat Bostonians must beware; the primary concern is the high humidity which might spawn storms capable of discharging torrential rain that could lead to localized flooding especially given forecasters predict a 40 to 60 percent chance of precipitation moving into the evening, alongside a moderate chance of thunderstorms post-2pm with new rainfall amounts of less than a tenth of an inch, though storms could bring higher totals.

While gusty winds and frequent lightning are also on the table, heavy rainfall and subsequent flooding remain the overriding anxiety, with most storms anticipated for Tuesday afternoon and evening, the downpours expected to possibly extend into the night. Post-frontal conditions on Wednesday forecast cooler temperatures as well as early rain, which might abate as we transition into the afternoon with the eastern wind introducing a fresher airmass, as the probability of precipitation persists at around 60% with showers likely before 11 a.m., and a chance of additional showers and thunderstorms later in the day.

Looking ahead to the remainder of the week, forecasts indicate more showers for Thursday with a 50 percent possibility for precipitation, and cooling temperatures as we head into the evening, Boston will witness a cloudy Thursday night with a chance of showers and thunderstorms the daytime high likely peaking at 74 degrees east wind around 6 mph, then milder conditions are expected to prevail heading into the weekend, with partly sunny skies and a more comfortable high near 83 by Saturday.
