Site log - Melbourne (February 1999) Flags: 1- Satellite coincidence data 2- Non-Satellite coincidence but still present in products A- Major problem (moderate to strong AP &/or widespread coverage) B- Minor problem (weak AP &/or very litte coverage) ***************************************************************************************** 01 Feb 99: Day starts with large area of weak to moderate stratiform precipitation moving predominantly onshore although motion of cellular components is slightly haphazard. Coverage of precipitation wanes near midday but increases and becomes more convective in nature after 13Z. By 18Z, a line of weak convection moves into range from the northwest, coupled with a strong cell just east of the radar. Convection intensifies and moves out over the Atlantic as the day closes.

At this time, another impulse of precipitation enters the radar's range from the west. By 18Z, a more impressive, weakly-organized line of convection enters the radar scope from the west. Convection holds together and intensifies slightly as the line moves across central Florida. By day's end, the still-significant convective line has pushed offshore.

Scattered convection develops ad moves into range from the west after 11Z. Cells stream westward, remaining north of the radar and training over the same latitudinal region, until dissipating by 15Z. More impressive convective cells enter the 150 km range from the west after 18Z. Once again the activity remains north of Melbourne as the cells track east and persist through the end of the day.
