A few morning showers will make for a damp start to the day on Sunday but they should last only until late morning when the cloudy skies make way for some sun.
"The last chance for showers should be late morning and then it should be partly sunny in the afternoon," said John Bristantello, a meteorologist for the National Weather Service in Upton. Highs will be in the mid-60s and lows will dip to around 40 degrees.
Lots of sun is predicted for Monday's bright start to the workweek when there's no rain in the forecast and highs will reach the mid-50s and lows will be in the mid-30s.
"Tuesday should be another sunny day with highs in the upper 50s and lows in the mid-40s," Bristantello said.
A chance for rain returns Wednesday when it will be cloudy and highs around 60 are expected. "There's a chance of rain more so in the afternoon and nighttime hours," Bristantello said. At night the temperature will drop into the mid-50s.
The clouds hang around for Thursday and Friday but the start of the weekend should be dry.
"Thursday starts out cloudy and there could be a shower -- most likely in the morning -- but it'll be mostly dry with highs in the mid-60s," Bristantello said. "There'll be a brief warmup then at night it will be in the upper 40s."
"It looks dry and partly cloudy for Friday," Bristantello said. Things cool down a bit with highs reaching only in the upper 50s and lows in the low 40s.
Bristantello said the temperatures for the week are fairly seasonable for this time of year at Islip when the highs are usually about 60 and the lows at night are in the 40s.
