NYC Weather Update – Sept 2, 2014

Despite the unofficial end of summer, today may very well turn out to be one of the hottest days of the summer! We’re looking at forecast high temperatures in the upper 80s into the lower 90s across urban areas. Some relief will be possible with afternoon thunderstorms, and then another round of showers and thunderstorms overnight. A few of these storms could be approach severe limits, however, despite the heat and humidity, atmospheric dynamics are not favorable for widespread severe weather.

Wednesday – despite the passage of the cold front above, temperatures will remain warm and humid with highs in the mid-upper 80s under sunny skies.

Thursday & Friday – essentially the same, hot, humid, sunny with highs in the mid-upper 80s. The culprit will be an area of high pressure that moves offshore and to the southeast Thursday. This setup will allow for hot, humid air from the Southeast of the country to pump into the area.

High pressure southeast of us allowing for hot, steamy air to enter the area.

The Weekend – we’ll finally see the heat break later Saturday and into Sunday as a stronger cold front brings in a cooler, drier Canadian airmass.
