500 mb heights and vorticity, March 7, 00z and 12z
Notes:
At 500 mb, a strong short wave tracked northeast from the Gulf coast states up the east coast to the northern mid-Atlantic area. The heights associated with this system indicated some deepening with time, but the upper low did not close off at 500 mb through 12z on the 7th.
