Models in agreement for a reasonably good coastal deluge with the brief formation of a coastal low. Good marine instability for coastal NSW, north of Newcastle IMO. The catalyst is the convergence of the polar upper-level cold pool and moist onshore flow off the Tasman. EC suggesting the low will land somewhere off the mid-north coast. Good directional shear and stacked PWAT should deliver falls upwards of 70-80mm in isolated areas, Monday into Tuesday. Snow lowering to 900m for the South Coastal Districts, early Tuesday IMO.
