With a frontal boundary remaining to the north of the area, temperatures surged to summertime averages throughout the Mid Atlantic region, breaking records in parts of the NYC area. Similar warmth is expected to continue on Wednesday, but the heat will be short lasting as a back door cold front moves through on Thursday, resulting in much cooler temperatures and increased cloud cover ahead of a low pressure expected to produce heavy rain on Friday.
Tuesday, April 9 Observations:
A strong ridge set up over the eastern US with a stalled frontal boundary north of the area along with generally mostly sunny skies, setting up for what was a record warm day across the area. Temperatures surged into the mid to upper 70s inland and the low to mid 80s for the rest of the area, with a mainly west wind preventing a significant sea breeze from developing over Long Island. The highest temperature was in Newark, NJ, at 85 degrees. Newark, including Islip, JFK and Bridgeport, broke heat records that were set in 1991.
