After another dry day with summer-like weather across much of Long Island, it will be a comfortable evening. Temperatures are cooling down now from highs mostly in the 70s and 80s. Overnight lows will mostly be in the 50s to lower 60s with a mainly cloudy sky, some patchy fog and a brief passing rain shower.

It will be another much warmer-than-average day on Friday, but not as hot with temperatures mostly in the lower to middle 70s. It will be in the 60s at the beaches. There will also be a spotty shower and downpour chance in the afternoon and evening, but any rain will be short-lived and isolated. Much of the day is dry with more clouds than sun at times.

Much cooler air arrives over the weekend and into next week. Saturday will be more seasonable with high temperatures in the upper 50s to lower 60s under a partly sunny sky. Highs will be down into the 50s on Sunday and Sunday will finally bring a chance of much-needed rain. Expect periods of moderate rain off and on through the day. Around one-half inch to one inch of rain is possible.

After the weekend, we return to drier weather for most of next week, but also even cooler air. Highs will be in the upper 40s to lower 50s on Monday and Tuesday, with even some frost possible - mostly Monday night into Tuesday morning.

Parts of Nassau County are officially in a moderate drought as of today's drought monitor update. While the dry weather is great for outdoor activities, Long Island does need more rain. If not, the drought conditions will likely worsen, despite the rain on Sunday.

Tree pollen levels continue to be very high and you are probably noticing that you are experiencing plenty of seasonal allergy symptoms. Sunday's rain should temporarily help with pollen before the dry weather returns for most of next week.
