The radar image above shows a Doppler Radar Storm Relative Velocity (SRM) product from 0449 UTC or 0049 LT
over West-Central Northumberland county. The Green/Cool colors indicate motion toward the radar (inbound)
velocities) while the Red/Hot colors indicate motion away from the radar (outbound velocities). The coupled
inbound - 36 KT/outbound -48 KT velocities imply a rotation on the order of 40-45 KT associated with this
storm.
