NEWS article

Mount Mawson 6th March 2019

quote from Ben ” 6th March 2019

Today’s taste of wintry weather comes less than a week after the state endured a day of record-breaking March heat.

Dover’s 40.1 degrees on Sunday was the first time on record any location in Tasmania has exceeded 40 degrees during March.

Eight other weather stations, including Hobart (39.1C), also beat Tasmania’s previous March maximum temperature record of 38.0 degrees on Sunday.

Impressively, Hobart’s 39.1 degrees on Sunday was also hotter than any day in the city during summer. Last season’s highest temperature was 37.9 degrees.

Sunday’s heat now seems like a distant memory, as much colder southwesterly winds flow over the state today.

Hobart was only sitting on 13 degrees at 10am, although wind chill was making it feel more like eight degrees.”

Report from Katoomba
by ‘IPEX’
http://forum.weatherzone.com.au/ubbthreads.php/topics/1272243/Re_Snow_31_July_2_Aug#Post1272243
“Very fortunate to be in Katoomba over the weekend and experience quite a good snowfall during dinner at the Savoy in Katoomba St on Friday night. About halfway through the meal there was a sudden murmur of delight and excitement in the restaurant, and I looked up and saw it was snowing outside. Quite a few people (myself included) went outside to experience the flakes close up. It eased up within a few minutes but settled well on the cars in that short time.

Then 30-40 minutes later (wasn’t really watching the clock) it started snowing again – this time much harder and for longer. We were leaving the restaurant at this time and walking up to the Carrington, and were quite impressed with the downdrafts and amount of snow falling. This time, it was sticking to the ground and on plants, not just cars, and for a time, it was quite blizzard-like, with the trees in Carrington Park bending and swaying in the wind and snow blowing everywhere. smile Lots of snow on the ground the next morning (Hinkler Park on Warialda/Katoomba Street had impress snow-drifts – for some reason, there seemed to be more snow there than anywhere else) and patches of snow persisted in the shade all through Saturday. On Saturday night, there was still snow in the backyard at the B&B we were staying in!
