Snapshots of atmospheric surface pressure anomaly and radar reflectivity during the first MCS.
Contours of atmospheric surface pressure anomalies cubically interpolated from TA (circle) and tide gauge (triangle) stations at (a) 0509 UTC and (b) 1420 UTC, overlaid on base radar reflectivity images from NOAA/WSR-88D radar stations (a) KPBZ and (b) KDIX, with radar locations indicated by magenta circles. Positive (negative) pressure anomalies (in hPa) displayed by thick (thin) black lines. Maps were created with software Generic Mapping Tools (GMT v4.5.12; http://gmt.soest.hawaii.edu).
