Boston citizens are in for a wet day, as confirmed by the National Weather Service, which has forecasted showers and potentially a thunderstorm before 8 am. The rest of the day isn't looking much drier with showers likely to continue between 8 am and 1 pm, followed by more showers and possibly another thunderstorm after 1 pm. The deluge contributes to a patchy, dense fog with the high hovering near 73 degrees under gusty conditions that could reach as high as 22 mph. The chance of precipitation is pegged at a soaking 90%, with new rainfall amounts between a half and three quarters of an inch possible.

Later in the day, the rain could persist, "showers likely and possibly a thunderstorm before 2 am, then a slight chance of showers between 2 am and 3 am," according to the NWS forecast. The lows will be around a humid 66 degrees, accompanied by patchy fog and gusty winds continuing to blow south at speeds up to 23 mph. The likelihood of precipitation drops to 60% tonight, with fresh precipitation between a tenth and quarter of an inch, except in thunderstorms where higher amounts are plausible.

Looking ahead to Friday, the weather situation seems to brighten up a tad by the morning as the fog clears. Bostonians can expect partly sunny skies with high temperatures nearing 81 degrees, and lighter west winds skirting around 8 mph, as determined by the National Weather Service.

Weekend weather offers a mixed bag, with Saturday anticipated to be mostly sunny and a comfortable 74 degrees. However, NBC Boston cautions "Sunday could see a few showers sneak in south of the Massachusetts Turnpike in the afternoon." If the showers do materialize, they're not expected to pose significant disruptions with their light and spotty nature, so local events, including the Patriots game, should proceed without weather-related hindrances.

Boston's early week forecast offers a return to sunny conditions, but nearby marine activity is worth noting. Two tropical systems—Humberto and possibly Imelda—are reportedly "swimming around in the Atlantic," although they are expected to stay clear of the New England coast courtesy of a formidable high-pressure system, as reported by NBC Boston. While winds may pick up and temperatures may take a slight dip throughout the week, the situation is generally favorable. "Better than a hurricane any day," adds NBC's coverage, providing a moment of sardonic relief to those navigating today's downpours.
