The next 2 weeks:

Here are the Long Island temperatures from the Euro for the next 2 weeks for the general idea, even though the ensemble mean is usually 2 or 3 degrees too low. Strong cold front with heavy rain and strong wind gusts (potential Wind Advisory scenario) for around next Sunday afternoon/evening, so temps might get close to 60 degrees next Sunday ahead of the front and only be in the mid 40's next Monday. Next Saturday looks like a good day for outdoor plans/activities with highs likely in the low to mid 50's on Long Island.
