A cool night with patchy cloud, with an overnight low of 7.9c. Currently; sunny spells,cool. Temp 8.7c Dp 8c Wind South 4mph Humidity 92% Rain Today 0mm Rain Yesterday 9.9mm

Will never forget that winter SS, nearly 3ft level here and snowed in for 2.5 weeks until the lanes were cleared. If we had a Nov/Dec/2010 this year, and another March blizzard where there were 16ft drifts in places here, I would be a very happy man.

A cloudy breezy night, with rain spreading in during the early hours, An overnight low of 10.2c. Currently; Moderate rain, Temp 10.6c Dp 9.7c Wind N/W 8mph Rain Since Midnight 6.9mm

Another dry night with fog forming during the early hours, im just on the fog line now with clear blue skys clearing above. Temp is now 9.4c the coldest it's been all night... Temp 9.4c Dp 8.2c Wind N/W 1mph Humidity 92% Rain Since Midnight 0mm

Could not stop myself posting the far distant chart from the GFS, showing a nice cold PM N/W flow. We would see the first snow over the Scottish mountains with that chart.

As the BBC keep saying, "drastic changes by the weekend". The models beyond this are really struggling with this up coming pattern change. An interesting few days model watching coming up..

QUIET SUNSPOTS: All of the sunspots on the Earthside of the sun are stable and quiet. NOAA forecasters estimate a slight 5% chance of M-class solar flares and no more than a 1% chance of X-class flares on Sept. 4th. http://www.spaceweather.com/

Another dry night, with clear periods and fog forming during the early hours, An overnight low of 9.1c Currently; Dry and clear, The sun has now broken through, with fog sitting in the valleys below. Temp 10c Dp 8.9c Wind S/W 2mph Humidity 93% Rain Since Midnight 0mm

Some fantastic footage from Alaska from last weekend, over 8 hours worth ! http://vimeo.com/73630309

Mathew Stewart shares with us this nice time lapse aurora video he captured very early this morning over Gull Lake, Alberta, Canada.

Another dry night.. with clear spells and patchy cloud. Fog formed above 400m in the early hours, but has all cleared now. An overnight low of 12.8c. Currently; Dry with hazy sunshine and patchy cloud. Temp 15.2c Dp 13.6c Wind N/W 4mph Humidity 90% Rain Since Midnight 0mm

1st of September Auroras. Geomagnetic Storming is not necessary in order to see the northern lights. Stuart Cant located in Scotland shot this fine example he captured last night . Even with a listed Kp Index of 2, here you can see a faint green glow and purple beams in the distance.

Checked mine last night to, the pinging sound reminded me of the coming season.

I'll take that chart CC...

Thought i would pop this in here from the BBC, talking about this years melt... http://www.bbc.co.uk/weather/feeds/23904997

A dry breezy night with sky's clearing at times, An overnight low of 11.1c. Currently; Dry and breezy, patchy cloud. Temp 11.9c Dp 10.4c Wind N/W 13 mph Gusting 32mph at 1.32am Humidity 91% Rain Since Midnight 0mm

Hope Lorenzo doesn't mind me copying his detailed thoughts from the regional thread... "Think my prediction about the atmosphere not kicking on until there was a Hurricane from a couple of weeks back is carrying some weight now." A couple of invest in the Atlantic , one with a chance of a tropical depression status in 6 days marries up well with the MJO pulling out of dormancy and the extra tropics being owned by weak Kelvin wave action. MJO kicking through the maritimes is like an ignition paper for upper level divergence, a cheeky wheelspin of African equatorial waves which will ignite tropical season, the following pacific action killing the wave 3 anchor across the hemispher and heralding a more mobile pattern. It's weird writing on the forum where winter north south divide is so very different from summer. The south hanging onto some good ridging and reasonable uppers. One major standout from the dogs breakfast ECM of the scrambled Scandi high for +144 next week is the Greenland Tip. There is a wee hint that what caused the trough disruption of winters past is a good 300 miles further east this year. If this is so and the atmosphere want to ghost this synoptic, without Stratospheric influence, whereby this year is a weak analog, then we are looking at a strongly mobile winter. Caveat is that this is just an early autumn read on seeing the trough disruption in FI, and for a good idea ahead we need to see the atmosphere base pattern ( strongly a drop in trough right now ) and shredding of systems... AFTER this MJO phase.. So November 05 12 GWO and MJO will be predictor of winter 13 -14, anything before that has some mighty guesswork. This year a late read, odds on no SSW influence, Brewer Dobson annihalated in summer , ozone transport delayed. at a guess now late feb / march again. with a zonal winter. until the 05th week November cannot tell http://forum.netweather.tv/topic/77270-scotland-regional-discussion16th-july-2013-onwards/page-24#entry277860

Thanks Lorenzo. Looks like you will be taking over GP's job during the Autumn/Winter months here on the forum ! Your input/thoughts will be greatly appreciated, as others..

Mega-Canyon Discovered Beneath Greenland Ice. August 29, 2013: Data from a NASA airborne science mission has revealed an immense and previously unknown canyon hidden under a mile of Greenland ice. "One might assume that the landscape of the Earth has been fully explored and mapped," said Jonathan Bamber, professor of physical geography at the University of Bristol in the United Kingdom, and lead author of the study published in today's issue of Science. "Our research shows there's still a lot left to discover." Hidden for all of human history, a 460 mile long canyon has been discovered below Greenland's ice sheet. Using radar data from NASA's Operation IceBridge, scientists found the canyon runs from near the center of the island northward to the fjord of the Petermann Glacier. http://science.nasa.gov/science-news/science-at-nasa/2013/29aug_megacanyon/
