SNOW AND HAIL-21st September
- Very cold air following a severe cold front which moved through north-east New South Wales late on the 20th produced showers of snow and hail on the higher areas of the Northern Tablelands. In Guyra there were a several light snow showers during the morning after 9am with a heavier snow shower at around 2pm which briefly settled on the ground. At 4pm there was a heavy shower of small hail (sometimes referred to as sago snow) which lasted for about ten minutes with 80 per cent of the ground whitened. Maximum temp: 6.5C, rain to 9am on 22nd: 0.4 mm, maximum wind gust: 55 km/hr at 12.45pm.

RAIN, SNOW, HAIL-24th August
- A severe cold front passed through north-eastern New South Wales in the early hours bringing moderate falls of rain to the Northern Tablelands and snow in elevated areas. In Guyra rain in the early morning turned to snow at around 7am, but only settled briefly on the ground. A moderate snow shower at around 11am, lasting about 30 minutes, also settled briefly before melting. During the afternoon there were a number of brief light snow showers, and also small hail (often referred to as sago snow or sleet). The maximum temperature was 4.4C at 9.50am, but strong winds throughout the day gusting to 60 km per hour kept the wind chill temperature well below zero degrees. Rainfall: 33.8 mm for the 4 hours to 9am with a further 6.0 mm falling during the day.
Further light showers of snow fell in the early morning of the 25th.


SNOW EVENT 20th-21st July -
A cold front with associated upper level cold air moved through the Northern Tablelands bringing snow to areas around Walcha and to the Guyra-Black Mountain-Ben Lomond area. In Guyra snow showers commenced at around 10pm on the 20th with snow settling on the ground. Further snow showers occurred through the night and morning of the 21st. At 6am snow was about 4 cms deep on the ground but gradually melted later in the morning. Very light snow continued until around 12 noon.

SNOW EVENT 9th-10th June
- Low temperatures, strong winds and showers of rain and snow occurred on the Northern Tablelands after a cold front passed through the region late on the 8th. A low pressure system associated with the front developed over southern New South Wales on the 9th which generated cold west to north-westerly winds over the north of the state. This surface system combined with upper level cold air caused snow to fall over the higher areas of the tablelands including Guyra, Black Mountain and Glen Innes on the 9th and 10th.
In Guyra:
Wed 9th - light flurries during the day, heavier in the evening with snow settling on the ground to a depth of about 4cm. Max temp: 4.4C.
Thurs 10th - light snow showers during the day but not settling. Heavier snow in the evening between 9pm and around midnight with snow settling to a depth of 8 to 9 cms. Max temp: 2.5C
Fri 11th - rain and higher temperatures in the early hours of the morning caused the snow to melt.



2020

2020 MONTHLY STATISTICS TABLE here.

2020 RAINFALL TOTAL: 
978 mm, 105 mm higher than the average. January, February, March and December all recorded above average rain with December being the wettest month recording 204 mm.

DRIEST NOVEMBER FOR 84 YEARS -
With a total of just 15.0 mm on 4 days it was Guyra’s driest November since 1936 which recorded 14.2 mm. Higher than normal temperatures and a lack of rain bearing systems resulted in the unusually dry conditions.

GUYRA HOTTER THAN ARMIDALE
- 30th November - The maximum temperature of 32.2C was a full 5.2C higher than the maximum in Armidale. This rather unusual event was brought about by a low pressure trough-line extending from the north-west of New South Wales towards the south-east passing between Armidale and Guyra. It remained in this position for most of the day. Thus north of the trough-line experienced hot north-westerly winds, while south of it enjoyed milder south-easterlies during the day. Glen Innes also experienced the “benefit” of this event with a maximum of 34.5C. Armidale recorded just 27.0C.

HAIL AND LIGHT SNOW -
22nd August - A severe cold front which passed through north-east New South Wales in the early morning brought showers of small hail and snow to higher parts of the Northern Tablelands. In Guyra there were a number of showers of soft hail (often referred to as sago snow or sleet) throughout the day, however there was only one brief very light shower of snow at around 12.20pm when the temperature dropped to 0.5C. The maximum for the day was 6.2C at 11am, however strong westerly winds kept the wind chill temperature to below zero degrees for most of the day.
Not recorded as a “snow” day.


AUGUST SNOW -
9th August - Light snow fell briefly at around 7am and 12 noon, and again in the evening. It did not settle on the ground but the Ben Lomond area received heavier falls which settled in the evening of the 9th and early morning of the 10th. An upper level cold pool of air combined with cold surface southerly winds associated with a low pressure trough produced the snowy conditions. The maximum temperature on the 9th was 4.4C.

LIGHT SNOW - 13th July - Very light snow fell briefly between 5 and 6pm but did not settle on the ground. Heavier falls occurred further north around Llangothlin and Ben Lomond. The icy conditions were caused by cold surface westerly winds generated by a low pressure system over southern New South Wales combining with upper level cold air. The maximum temperature on the following day the 14th was 5.0C.

COLD OUTBREAK AND SNOW
- 22nd-23rd June - Very cold winds combined with an upper level cold pool following a cold front which passed through eastern New South Wales on Sunday 21st, resulted in very light snow on the higher parts of the Northern Tablelands on Monday evening the 22nd. Light non-settling snow fell briefly in the evening at around 9pm in Guyra. Low day temperatures followed on Tuesday 23rd with Guyra recording a maximum of just 3.8C.

JUNE SNOW -
2nd June - Snow fell for about an hour from 8.30 to 9.30am but did not settle on the ground. Very cold conditions resulted in light snowfalls along parts of the Northern Tablelands including Armidale. Cold south-westerly winds following the passage of a cold front the previous evening, and an upper level cold pool caused the extreme wintry weather. The maximum temperature in Guyra for the day was 5.3C.

The unusually hot conditions were caused by low pressure troughs lingering over western New South Wales for most of the month drawing hot air into the state from central Australia.
