Hail Reports
Sun 7th	Golf ball sized hail observed on the Central Coast during the early afternoon.
Mon 8th	Golf ball sized hail observed in Raymond Terrace during the afternoon ~1545 according to the ABC radio.
	On my travels around RT soon after I found no evidence of any hail at all in the local area, we did however
	receive torrential rains with the storm that produced some localised flash flooding. BoM stated the hail size
	in their warning as an actual report. Possibly occurred in a nearby area (probably toward the N) with the
	heavy rains ensuring anything icey would have melted quickly.
Mon 29th	A large storm moved in ~1445 producing gusty winds to 64.4km/h, torrential rain (highest ever rainfall
	rate I have recorded so far of 300mm/h), along with a light amount of small hail. Medowie also received small
	hail though golf ball sized hail was seen both in Morrisset on the Karuah bypass, all from this one cell.
Instrument Additions & Alterations
Thu 4th	Electronic grass thermometer stopped working due to old age. Attempted to replace with a new sensor but
	the small wooden box it was housed in also disintegrated due to old age. Used standard BoM grass
	thermometer from fri 5th onwards until I can put another box together.
