Even the heat is getting to the good folks over at Upton:
"
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
Forecast area will remain at the southern edge of the westerlies
with broad upper ridging across the southern half of the country
merging with the subtropical high over the western Atlantic.
Anomalously warm heights aloft, deep westerly flow, and high
boundary layer moisture (high humidity) will result in dangerous
heat indices through early this evening. Even overnight, the
urban corridor and coastal sections will see dewpoints in the
mid 80s to around 90. While there will be some relief overnight,
it will remain a hazard for living premises that are not ventilated
well or do not have AC.
