Hail Reports
~ Mon 3rd - My parents observed at least marble sized hail & torrential rain to the near W of RT.
~ Sun 9th - A little further from home but impressive nonetheless, Sydney observed hail in the 7-8cm range. Even heard
reports that their 2nd largest stone was even observed!
Weather Chases
~ Tue 4th - Chased storms in the hunter from the Maitland area.
Instrument Additions
~ Mon 10th - Installed new Rain Gauge (TB3), I will begin officially using from 1 Jan. My Nylex will be used as a backup.
~ Purchased a wireless thermometer for use in the Barrington Tops. Began testing from the 13th against both my AWS &
official BoM standard thermometer. Accuracy seems excellent so far, will continue testing thru Jan.
Instrument Repairs
~ Tue 11th - AWS thermometer began having problems after the cable was disturbed the previous day with my TB3.
I ended up replacing both the modular plug & joiner. This thankfully fixed the problem.
