It was looking promising that the
residents of Gungahlin (Canberra) would wake to a 'winter
wonderland' scene, with a thin layer of snow covering the ground
on July 18.
The ACT Weather Bureau had forecast
snow down to 500m o/night on July 17 and into July 18. The
Gungahlin Weather Centre is 634m.
The forecast read "A very
cold air mass associated with the change is expected to bring
showers, falling as snow to around the 500-600 metre mark across
the ACT Tuesday night into Wednesday, with good potential for some
snow showers to fall over the Suburbs of Canberra".
Unfortunately, despite the hype, all
we woke to on 18 July was cold SW winds and mostly clearing skies.
Snow had fallen across the Brindabella Ranges to low levels, and
the snow capped mountains surrounding the city looked spectacular
in the early morning sun.
The expected cold change did bring
2.5mm of rain to Gungahlin o/night, but this fell between 6.30pm
and 7pm when the temperatures were still too warm for snow.
It was 4.6°C
at 6.30pm, and 3.3°C at 7pm. No
rain fell after 8.15pm (temp 3.4°C)
and by mid-night there were stars in the sky and the temp was 1.6°C.
Hopefully it won't be long until we get that snow fall the kids of
the region are waiting for - including big kids like me!
