Initial Impressions:  This flight consisted of the basic Flight Track 1 survey (minus the C-F-G triangle).  Large-scale conditions included warm, SSE flow at low-levels with continuous precipitation mostly in the northern portion of the experimental domain.  The 500’ run along the coast found first easterlies of about 15 knots out of Cross Sound and then a gradual windshift towards winds from about 135 degrees at 30-35 knots near the north end.  The thetae generally was lower in the outflow air than the more coast-parallel flow farther north.  The stack between C and E encountered a couple of weak shore parallel rainbands.  The first run out to E indicated somewhat cooler temperatures near the coast but little in the way of a wind shift.  The stack and the porpoising indicated weak convective instability in the lowest few thousand feet.  The wind speeds were more or less constant between about 500’ and 2K’; veering was noted in the lowest 1K’, presumably mostly due to friction.  Significant turbulence was confined to near the surface.  The instrumentation seemed to work well, with the exception of a glitch in the data recording system, which caused an outage of two minutes in the 500’ leg from C to D’.
