HELTER-SKELTER IN THE SUMMER SWELTER


1. Weekend weather will be characterized by warm and increasingly humid conditions, with the best chance of afternoon/evening storms (scattered) coming on Saturday.

2. Hottest day of the summer thus far is poised to arrive for Sunday; temps make a run at 90 at most locations. Even Long island’s shore communities can briefly touch 90 degrees before the local sea breeze develops in the afternoon. Although actual highs will be in the lower 90s, very humid conditions will make it feel like it’s in the upper 90s to near 100. 

3. Strong potential for heavy rain/thunderstorms Monday, in the late morning/early afternoon. Unstable air mass Monday will have the “trigger” in the form of a potent cold front as well as a mid-level disturbance to spark widespread storms.  Update coming Sunday to address this further.

4. Tuesday and Wednesday are warm, but less humid, with perhaps a light passing shower on Tuesday evening. Next chance for more organized storms comes about next Friday.

A LOOK AT THE WEEK AHEAD

1. After a classic summer weekend of sunshine and temps in the 80s and 90s, we'll see slightly cooler conditions for Monday. Light southeast winds will keep temps in the mid 80s under sunny skies. Clouds come in late in the day and continue to build overhead for Monday night, with an isolated shower in a few places very late Monday night.

2. Tuesday is cloudy and humid. Late day showers and thunderstorms are a good bet Tuesday afternoon and night .  Weak steering flow in the atmosphere will allow storms to dump heavy rain.

3. Position of a weakening cold front will determine Wednesday's overall weather. Low confidence due to the variability of the models; this will have to be addressed in an update, which will come sometime tomorrow night. For now, plan for a good chance of an afternoon or evening shower or thunderstorm.

4. Sunshine returns Thursday through Friday, with less humid conditions. Temps will stay in the 80s. More humid Saturday; an isolated shot at scattered storms comes about by Saturday afternoon and night, with the greatest risk for storms during the weekend being Sunday as a cold front enters the region.
