Saturday was a spectacular late-September day in Southern New England. The high temperature was in the low to mid 70s in RI and upper 60s to low 70s in SE MA. The afternoon sky was a combination of deep blue and white puffy clouds. Saturday night will be mainly clear and cool, with lows in the 40s in the countryside and near 50 in the cities and at the coast. Incidentally, Saturday’s low temperature was 48° at TF Green Airport. That is the 12th day this month with a low temperature at TF Green below 50°. That has not happened since 1988.
After a clear cool start, with great weather for the runners of the Rock ‘n’ Roll 1/2 Marathon in Providence, the afternoon should be just fine in Southern New England. It will likely be a few degrees cooler than Saturday, but close to normal, with highs in the mid to upper 60s. There will be a 10 mph easterly breeze. It will be mainly clear Sunday evening, with clouds increasing after midnight. Lows will be in the low to mid 50s with a northeast breeze.
The forecast is tricky for Monday. Even at this late stage of the game it is uncertain whether an ocean storm will have an impact in Southern New England. Right now, it looks like the storm will stay far enough offshore to, at worst, throw some rain showers and a gusty northeast breeze at RI and SE MA. It’s still possible the storm is far enough offshore that there will be no rain or noticeable increase in the breeze. The forecast is for mostly cloudy skies, scattered showers and a 10-20 mph north-northeast breeze with a few higher gusts in E MA. Highs will be in the low to mid 60s.
After a cool September, October will begin with warmer than normal weather. Tuesday should be mostly sunny with highs in the low to mid 70s. It will be even warmer on Wednesday and Thursday. Wednesday looks like the warmest day of the week. Highs will flirt with 80° inland, and it will be in the 70s near the coast. Skies will remain mostly sunny. The weather will stay fine, and warmer than normal through the end of the workweek. The outlook for next weekend is for some showers as a cold front moves through the Northeast. The timing is uncertain, with a early estimate of mid-weekend as the most likely time for showers.
