Weather Synopsis...

A 1018mb area of high pressure was located to the southeast of Cape Cod. The resultant synoptic wind flow is from the south and southeast.

Seabreeze Analysis...

The radar loop from KDIX shows the seabreeze forming along the entire length of the NJ coastline and then moving inland.

The graphs of air temperature and wind direction below for Avalon, Atlantic City, and Long Beach Island show that the seabreeze passed by these locations from north to south. At LBI, the farthest north location, the seabreeze passed by at around 1000 local time, or 1400Z. At Atlantic City the seabreeze passed by around 1100 local time, and it passed by Avalon around 1200 local time, or 1600Z.

SST Discussion...

The SST image from 0835Z shows pockets of cooler water off Absecon Island (Atlantic City) and Sandy Hook.

The 2354Z SST image indicates that the ocean water temperatures had rebounded to an almost uniform 21 degrees Celcius along the NJ coast. This is likely due to the advection of warmer offshore water by the east wind resulting from the seabreeze.

CODAR Information...

The CODAR plots shown below are from 12, 20, and 23Z. The 12Z plot shows a SW current right along the shoreline. By 20Z, the current had changed to an onshore direction. By 23Z, the effect of the seabreeze had diminished and the current had changed to a NE direction.
