![]() ![]() Doppler observations can also reveal the presence of flocks of birds over Port Phillip Bay, which appear as thin lines, and generally have a higher velocity than the surrounding area. These appear as radials of incorrect Doppler velocities in the area to the northeast of the radar. These echoes may be distinguished from rain as they do not move with the wind and end abruptly at the shoreline of the bay.Doppler observations are occasionally affected by multi path reflections off Melbourne City buildings and approaching rain bands. Because the radar has an unobstructed view of Port Phillip Bay out to about 25km, sea-clutter may be seen over the bay during strong winds. These usually become more noticeable on cold, clear, winter nights or early winter mornings. These echoes usually occur along ridges and peaks as isolated, stationary patches, being most common near the Yarra Ranges to the ENE and Mount Macedon to the north. Occasionally, some permanent echoes will not be completely removed from the display. Non-meteorological aspects In most cases the processing of the radar signal removes permanent echoes caused by obstructions such as hills, buildings and other solid objects rather than rainfall. The location on the floor of a wide basin is ideal for Doppler observations which provide wind speed information. Similarly, cold fronts and associated rain and thunderstorms approaching from the northwest, through west and south are well detected. ![]() Summer thunderstorms that develop on the surrounding hills and mountains may be observed in detail. ![]() The high ground from the east, through north and to the south west tends to obscure shallow rain falling further away. Meteorological Aspects The radar is well sited to provide very good coverage for the Greater Melbourne Metropolitan Area. The most significant obstructions, starting from the east, are: Mt Dandenong 644m high, 53km to the east Yarra ranges 1219m, 83km to ENE Mt Macedon 1013m, 56km to the north Pentland Hills 763m and the Brisbane ranges 421m, 45km from the NNW through to the west and the You Yangs 363m, 30km to the SW. The Great Dividing Range dominates the topography from the east, through the north to the west.

The radar is on a tower 24m above ground level. Weather forecast and conditions for Houston, Texas and surrounding areas. All Rights Reserved.Geographical Situation The radar is situated on the western plains of the Melbourne basin some 19km west-south-west of the Central Business District, about six kilometres from the western shores of Port Phillip bay and on a low rise about 20m above mean sea level. This will need to be monitored over the next couple of days with updates to come. The entire area is under at least a marginal risk of flooding, but there's a slightly greater risk in and around the city and across the interior. Looking Ahead: Sunday looks more active, especially in the afternoon and evening, with the potential for a few strong storms and even some flash flooding. ![]() As for tomorrow, expect iso'd showers and rumbles of thunder with highs in the mid 80s and feels like temps near 90. The shower/t'storm activity should wind down by about 8PM with things remaining quiet the remainder of the night. Expect highs in the 80s with feels like temperatures near 90.

The main threat from these storms will be locally heavy rain that could lead to some flooding. Houston Weather: Fourth of July Forecast. Forecast: Today will be another hot, sticky day with a chance of some isolated showers/t'storms this afternoon, especially inland. ![]()
