A heat wave is on for the end of August, and will persist into the beginning of September. A hot, humid tropical airmass will be firmly in control through out the early and mid-week period before we get some heat relief late in the week. The hot temperatures and a lack of widespread precipitation may allow drought to redevelop in some parts of the region, and worsen over Long Island.
Rest of today – possibly the hottest day of the week, with temperatures in the low-mid 90s inland despite some cloud cover and uncomfortable humidity levels.
Tuesday – a weak backdoor cold front pushes through overnight, although no precipitation is anticipated due to insufficient instability. Tomorrow should see high temperatures in the lower 90s again under sunnier skies.
Wednesday – the heat wave continues with temperatures yet again expected to top out in the low-mid 90s with sunny skies. There could be a few isolated pop-up showers/thunderstorms late in the day with very limited coverage.
Thursday – expected to be the last day of the heat wave, sunny with high temperatures at or above 90.
The heat will be the main weather story of this week, with temperatures of 90ºF or higher forecast to occur for a majority of the week. This heat does not appear to abate until at least this weekend. Incidentally, according to the Chinese lunar calendar, we’ve just hit 大暑 (literally “big heat”), a period of 2 weeks that are supposed to be the hottest of the summer. Fans of the heat, it is time for you to rejoice.
Rest of today – clouds this morning should slowly give way to more sun in the afternoon. The cloud cover now will help keep temperatures in the mid-80s.
Tuesday – a chance of showers and thunderstorms in the morning, but otherwise hot with highs in the low-90s and a good amount of sunshine.
Wednesday – shaping up to be the hottest day of the week, with high temperatures in the mid-90s.
Thursday – with a cold front approaching from the west, there may be a few thunderstorms in the afternoon on Thursday which might grant some reprieve from the heat. Otherwise, sun and clouds with a high temperature in the low-90s.
The first half of this first full week of the summer felt very much like mid-summer, with hot, humid conditions and even some severe thunderstorms. The second half of this week, along with the weekend will feel a lot more like late spring, with Saturday afternoon into Sunday morning shaping up to be a washout.
Rest of today – pleasant, sunny skies, with a wind from the northwest, will yield comfortable high temperatures in the mid-80s.
Friday – an area of low pressure will be tracking eastward from the Midwest along a nearly stationary frontal boundary that will be positioned over southern New Jersey. The timing of this wave of low pressure will be overnight Thursday into Friday morning. Rain should end by noon Friday. With mostly cloudy skies, high temperatures will only top out in the mid-70s.

Saturday – the respite from the rain will be short-lived. Saturday morning into the early afternoon should remain rain-free, though temperatures will again be suppressed in the low-mid 70s. Another, more potent area of low pressure will make its approach from the west during the day Saturday. The precipitation shield associated with this low should begin to fill in over the area beginning in the mid-afternoon hours. Periods of showers will continue falling, with moderate to heavy rain at times, throughout the remainder of the day and overnight Saturday.

Sunday – rain begins to taper off on Sunday from south to north as the center of the low pressure responsible for this storm moves to our northeast. Rain should end in the early afternoon hours. Mostly cloudy skies are expected with temperatures in the mid-70s. Rain from last week has put a dent in drought conditions across New York state, but areas of Central upstate New York and eastern Long Island could still use this rain. The downside is that it will put a damper on many outdoor plans for the first full weekend of the summer, and the first weekend after school ends here.
Monday – conditions improve on Monday as the low pressure continues to pull away. High temperatures should remain in the mid-70s with cloud cover decreasingly steadily.
