Aug 31, 2012: Cooler Start To September

Thursday, August 30 Observations:

Morning temperatures were quite chilly with the trough over the region from Wednesday, dropping as low as 47 degrees in interior areas, with widespread 50s observed outside of NYC. Lows in NYC dropped into the low to mid 60s.

High temperatures were warmer than Wednesday as the high pressure on top of the region continued to slide southeast, with a more westerly flow developing resulting in a very warm air mass quickly making its way in. Temperatures reached the low to mid 80s across most of the area with upper 70s in a few spots.

Friday, August 31 Observations:

A brief yet intense surge of heat moved through the region on Friday into Saturday, bringing a quick 2-day round of 90 degree temperatures. Highs reached the upper 80s to low 90s across most of the area with mostly sunny skies, with cooler temperatures observed further east into eastern Long Island. The hottest temperature was 94 degrees in Newark.

Forecast Overview:

Following today’s brief heat surge, cooler temperatures will return into the area for the weekend along with dry conditions persisting, with highs on Saturday in the mid 80s for most of the area, a bit warmer in the immediate NYC area and cooler further east, and dropping into the mid 70s to low 80s for Sunday and Monday with more cloud cover and the risk of a few isolated showers.

More widespread storms are expected for Tuesday and Wednesday, especially late into Tuesday, as Isaac’s remnants drift into the region. Risk of severe weather, if any, is still uncertain, although the potential is there for heavy rain with the remnants. Temperatures are likely to remain in the upper half of the 70s with occasional low 80s. Drier conditions appear to return for the end of next week, although no significant change in temperatures appears to be on the way, at least not yet.

More information on the outlook for Isaac’s remnants, as well as an update on Tropical Storm Leslie, will be posted on Saturday.
