A pair of stormy periods here 7.15am, and later in the morning (I was driving to Melb then), and persistent light easterly drizzle since has provided 20.75mm to start us off for this event. Here is the present synoptic:
This is (to me) still a unique situation. We have an anomalously strong (for early Jan) high 1026hPa at a sub-Tassie latitude, a classic summer easterly dip over inland E/SE Aus continent, and for Gippsland, ....we have a fresh easterly, with the classic low level scud clouds and persistent thick drizzle training in from the east all day, ...yet the rain bands when tracked via the radar, are arriving in streams from the NNW (the "normal" storm tracks).
Normally in these situations, the radar shows the rain bands tracking along (matching) the mean sea level pressure gradients.
If I'm wrong in this perception, please let me know. We are always learning, ......and as you get older you finally realise "you aint yet seen it all".
