Frontal Passage "Gust Front" March 29,
2003
A convective line of thunderstorms
passed over WeatherMatrix HQ in State College PA just before 11am on March 29,
2003. This line, although up to 56dbZ on radar, contained no lightning, as
reported by official (GAI) and unofficial (our
detector) sources. 56dbZ is very high to not be producing lightning and the
resulting "gust front" looked no different than a summer thunderstorm gust
front. High winds were observed and the pressure spiked 0.06" in about 15
minutes while the temperature fell 10 degrees in 10 minutes (see graphs
below).
