Observed radar reflectivity mosaic (dBZ) at 2 km MSL from KTLX, KVNX, KFDR, and KINX Doppler radars valid at (a) 2200, (b) 2220, (c) 2240, and (d) 2300 UTC; simulated radar reflectivity (dBZ), horizontal winds, and vertical vorticity (contours starting at 0.004 s−1 with an interval of 0.002 s−1) at 2 km MSL from NoDP2 valid at (e) 2200, (f) 2220, (g) 2240, and (h) 2400 UTC, and from DP2 valid at (i) 2200, (j) 2220, (k) 2240, and (l) 2300 UTC. The duration 2200–2300 UTC covers the 1 h forecast period.
