The Providence area saw a third straight day with highs in the 90s on Saturday. It’s the first heat wave at TF Green Airport since mid-July of 2012. It is very likely that it will become a four-day heat wave on Sunday. Saturday night will be mainly clear to partly cloudy an quite mild. The humidity may drop just a bit overnight, but the temperature will stay in the low to mid 70s. A bit of patchy fog is possible near the coast.
Sunday will be another hot day with partly sunny skies. There is the chance of a passing afternoon or evening thunderstorm. The high temperature should be similar to the past few days, with highs in the low 90s inland and 80s at the coast. It may be a bit less humid inland, with dew points in the afternoon in the mid to upper 60s instead of the low 70s. If the wind is out of the southwest near the coast, that will help to keep the dew points in the 70s at the beach.
The wind will swing back around to the southwest for all of Southern New England Sunday night as a disturbance approaches from the west. The low temperature will be in the low to mid 70s, with the chance of a passing thunderstorm Sunday night. Monday will be partly sunny, breezy, very humid and warm, with scattered showers and thunderstorms possible throughout the day. Highs will be in the low to mid 80s near the coast, and 85-90° inland.
The weather looks fairly quiet on Tuesday in the wake of the departing disturbance. Highs will be in the 80s with partly sunny skies. Another front will approach Southern New England on Wednesday and Thursday bringing a renewed chance of scattered showers and thunderstorms. Highs will be in the 80s, and lows will be in the mid 60s to low 70s.
