Center of Attention


The surface LOW pressure center passed just S of Westhampton Beach , NY...home of the KFOK ASOS this afternoon. ASOS observed it passage just before 3 PM EST (20z).

Note the breezy 17G25KT wind from the ENE back into NW then N...and diminish to all of 3KT. Blowin' like stink one minute...almost dead calm the next. About 35 minutes of becalmed conditions ended when the backside of the LOW blew in on a 24G33KT wind bringing FZRA and sharply colder temperatures with it. The temperature fell 8°C (~14°F) in about 90 minutes. The 40°F mP dew point dropped to 25°F in cP.

The reason the horizontal wind stops blowing in the center of circulation is b/c all the air movement is going straight up.
