980517 - Our target was the dry line in the Texas panhandle.  As in
previous days, we were plagued by low visibility from the smoke making
visual identification of targets difficult.  Since no significant
convection developed before dark, this was not a problem.  Two mobile
mesonet vehicles made multiple passes through the dry line collecting high
resolution data on this feature.  Not suprisingly, the structure was quite
complex and showed large variations from one pass to the next.  Sounding
data from AMA indicated that there was little or no CIN left and convection
should have initiated during the afternoon.  This case should provide some
interesting data for the analysis of dry line structure at the surface.
