In addition, the ambient air within the stratiform region has usually already been evaporatively cooled to a significant degree by the preceding convection. Meanwhile, the rainfall rate in the stratiform region is much less, which results in less potential for evaporative cooling. Rainfall rates will likely be much higher in the strongest convection, thus increasing the potential for strong evaporative cooling.

This can be explained further by comparing the rainfall rate in the region of strongest convection to the stratiform region. Within this area, evaporational cooling is not able to balance the adiabatic warming that occurs due to the descending rear inflow jet. As described by Johnson and Hamilton (1988), wake lows form within the stratiform precipitation region behind the strongest convection. This data is consistent with other case studies ( Handel and Santos, 2005) and numerical modeling of wake lows ( Johnson, 2001). At the same time, the temperature rose 7 degrees and the dew point dropped 7 degrees. The wind gust peak at 69 mph around 0753Z and again at 0841Z. The rapid fall drop in pressure between 0700Z and 0800Z corresponds to a sudden increase in sustained winds and gusts.

The changes in temperature, pressure, and wind are best seen through these time series charts.
