Severe Nighttime Temperature Increase!!! 12 Nov 2006
« on: 13 November 2006, 04:28:22 PM »
Look I know this is pushing the boundary of "severe weather" But I can't believe what has happened here tonight. I can't recall ever seeing such a sharp temperature increase at night time like this ever at Penrith. Check out these obs because between 9pm and 945 pm the temperature rose 7 degrees from 23.5 to 30.3!!! Yes it is nighttime! The rise was accompanyied by strong NW winds coming off the Blue Mountains and i'm sure we just had possible foehn style wind event here. As you know falling air off mountains can heat up quite rapidly as it drys out and as I talk i'm breaking into a sweat at 1025pm!!! What a strange year we are having! And to think that there is a major cold pool coming the likes of which we didn't even see last winter!

Jeff.

Obs from 10:11 backwards with the temp at 10:11 of 29.4
