Live Storm Investigation : Pressure Drop 1/9/98
As the frontal system moved out of the NE US on Friday,
it brought high winds to isolated areas including Central Pennsylvania.
Member Howard Reicher files this report of
a sudden pressure fall. Unfortunately no other CASI members or reporting
stations were close enough to record additional data on the event.
Neither Pittsburgh nor Washington was able to record this rare mesoscale
event. If anyone has any additional data on pressure fluctuations that
night please e-mail CASI.
