A line of strong thunderstorms moved across Texas into SE Louisiana. Behind
the front associated with this squall line winds are from the N. The timing
of frontal passage was not optimal for producing a fallout but the N winds
and the fact that this is the absolute peak of migration when the traffic
rate is at its highest should make up for any other factors to produce a
respectable grounding of migrants in the short term. As high pressure
settles in and brings a stable and tranquil airmass over the wester Gulf
coast the emphasis will shift from diurnal arrivals of trans-Gulf migrants
to evening departures.
