More of the same. In general terms, that’s what we expect to see in the next couple of weeks in the Northeastern United States. The humidity will be somewhere between muggy and tropical through early-August. The shower and thunderstorm threat diminishes between Friday and Monday, with just a pop-up t-storm or two possible on Saturday as a front eases through. It will be seasonably warm during the day with highs in the 80s. Expect warmer-than-normal nights with lows in the 60s Sunday and Monday, then back into the 70s for most of next week.
Showers and t-storms will become more numerous by late Wednesday into early Thursday. The best chance of heavy rain is Wednesday night. Scattered showers and storms continue through the day on Thursday. There is a decent chance that many RI towns will get about an inch of rain in the next couple of days. Of course with a tropical airmass in place and the showery nature, the potential exists for higher or lower amounts. It looks like western RI has the best chance for some 2″ amounts, and totals should be lower in Eastern MA – especially Cape Cod.
Friday will be a dry and warm day with some sunshine and muggy conditions. A cold front moving through late Friday night or Saturday is the impetus for scattered showers and t-storms. The timing of the front is important for outdoor events on Saturday. It may lag enough that showers/storms pop up midday into the afternoon, especially in Eastern MA.
Sunday and Monday looks fine with slightly lower humidity. The shower threat returns late Monday through the middle of next week. I do not expect total washouts any day next week, but splash and dashers are likely.
