After a tepid June with warm and cool spells mixed with times of wet weather, meteorological summer is off to a reasonable, seasonable start on Long Island. In the last week of astronomical spring, summer-like weather will be in full force, with sun, heat, humidity and thunderstorms.
After another beautiful weekend, high pressure starts to lose its hold on the area's weather on Monday. Another cool night with lows in the 50s for Long Island Sunday night leads to a warmer Monday with highs around 80 degrees. There will be a limited seabreeze for our shoreline friends. Humidity levels, at a comfortable level over the weekend, will be noticeably higher on Monday.
An area of showers with embedded thunderstorms will approach the tri-state area Monday evening and Monday night. This could touch off some rain to come through very quickly with little fanfare. This brings a warm front through, which leads to hotter temperatures for the middle of the week.
Tuesday will be a favorite among summer lovers. Mostly sunny skies and higher humidity levels are expected with highs in the 80s. A seabreeze keeps it a bit cooler at the south shore, but not by much with such strong mid-June sunshine.
Wednesday, a cold front approaches bringing the chance of thunderstorms late in the day. Otherwise, it's summer to the max. Even a little sun, and some areas of Long Island could see 90 degrees for a high temperature.
Overnight lows are in the 70s with a muggy feel, so rev up the air conditioning.
The cold front comes through, but just barely. It may get hung up just to our south, keeping us in the clouds Thursday and maybe Friday as well. Thunderstorms may be in the forecast for Thursday, should the front stall close enough.
