• Description:
  With the increased emphasis on putting more resolution into the local forecast, forecasters may tend to look for clues in the mesoscale; whereas, the answer may lie in the synoptic scale. This may be true even in the doldrum days of mid summer. In this paper, a case is presented in which the synoptic scale overwhelmed mesoscale influences; yet detail could still be added to the forecast by being familiar with the cloud distribution model associated with a vorticity maximum as described by (Weldon, 1983) . More importantly, the forecaster can avoid wrongly updating a forecast (to agree with observed conditions) simply because radar shows the echoes to be moving away from the area of concern, by being aware of Weldon's model.
