anyone got snow this morning? plenty of showers around.
-
No mate, it only effects weather patterns in the short term as it fluctuates up and down. Its basically represents the pressure patterns in the Atlantic, so if we have High pressure over Northern Atlantic towards Greenland ( not a Greenland surface high ) and lower pressure down towards the Azores then that's a negative NAO and favors colder weather for us. Positive NAO is pretty much the opposite and is the normal typical zonal weather we see here with lower pressure in the Northern Atlantic and higher pressure towards the Azores.
So if we see the NAO drop negative then it increases the chance of snow in the short term and will not affect years ahead. Hope this helps. I'm only a novice and im sure someone could explain it better.

That's kinda odd.. I'd expect York to have an air frost more then us..
I use York university's weather station. Its very high tech and would be surprised if its wrong. Played golf in York this morning and it certainly wasn't as frosty in York as it was here near Malton. Strange one really :S
Just noticed Linton on Ouse 8 miles northeast of York official Met Office weather station got down to -2.7Cat 5am. Must be an error with the University's station.
-
Currently -0.2C. Frost reforming after a slight thaw although grass in shade stayed frosty all day. Max 3.1C and a beautiful crisp winters day. Second best to snow
-
Had 3 air frosts and 3 ground frosts here, got down to -3.2 last night, the lowest so far this winter. Frost lasted all day and is growing currently although i expect to be gone by morning. 15 miles west York has had no air frost with a low of 0.1 last night
-
0.8C here and clear skies. Grass frost already
-
just had heavy sleet here, left alot of the roads flooded. shame it didnt fall as snow
-
Clear blue skies, 1C and frosty. Few showers made it this far east but fell as rain due to being light.
-
Wahey snow made it to the North York Moors. Few cm at the top of Sutton Bank. Bit dodgy driving up a 25% gradient hill in the snow but worth it when i reached the top. Snow line is around 250m. Nice to see some eastern parts can get snow too
-
In North Yorkshire the North York Moors is defiantly the best place to be, high elevation and very exposed to both Northerly and Easterly winds. After that the Yorkshire wolds can receive massive accumulations of snow whereas the vale of York can sometimes have 50% less. Last December we had 13 inches in York, whereas Thixendale in the wolds 18 miles east had 24 inches. Last winter Westerdale in the North York moors received 44 inches during November and December which is just mind blowing.

Could have gotten an air frost here, but of course, wind or cloud ruined the chances! If this type of thing is gonna occur every clear night then I get the feeling that December will be air frost free! (okay, so that's unlikely, but still!)
You seen radar mate? Could be something wintry anywhere with elevation near you.
-
1.8c here so a ground frost for certain not sure about air frost as I hear talk of an easterly breeze and I'm only 20 miles from the coast hope it stays off till the morn.
-
Beautiful day here. Nice for it to feel like November for once with a max of 9.6C. Took dog for walk this afternoon and the contrast between golden trees and clear blue skies was gorgeous. Temp dropping already now to 8.3.
-
.I think that while we are all looking for the next pattern change, we are missing the fact that almost no rain looks to fall in eastern England for the next week or so. Exceptionally dry.
Glad to have a dry week here. Our garden is a mudbath and extremely saturated. 18z ensembles still keeping the cooler trend with more members going even colder in F.I. Mean still around average but still positive signs heading into the latter part of the month. Also worth noting that the pub run is on the warm side throughout the run.
-
7.7c here. Been cloudy with drizzle this afternoon skies have now cleared leaving a lovely evening for fireworks.
-
Raw CFS data looks good
Fancy sharing a cheeky chart for those poorer snow freaks?
looks interesting....very interesting.....
-
If we are still getting Southerlys by 240hr il be very surprised. I think a pattern change is inevitable and by this time next week we will know exactly what will happen. Not sure exactly how accurate the ensembles are but for a few days now I've been watching them and a cooler trend towards the end of month is looking more likely. For Aberdeen the ensemble mean drops to near -5 hpa and for here around 0 hpa. This would suggest a northerly wind is most likely. Definatley going to be watching the charts closely over the next week.
-
Fantastic storm. Chased it from malton to Scarborough and watched it head north from olivers mount. Very unexpected and certainly the latest in a year I've ever seen a thunderstorm. Constant flashes and some close cg's when driving through the Yorkshire wolds. Great stuff!
-
Cold again this morning with a minimum of 4.4C clouded over around 7am but it's now sunny again and feeling pleasant with rising temperatures at 11.4C. A fine weekend so far.
-
Currently 14.1C and clear blue skies, overnight low was 4.3C very close to a ground frost. Beautiful autumnal day

Earliest 19th of October and latest 5th of December. Most likely to have the first air frost here around mid November id say.
-
Top temp of 13.9 today. Rather blustery. Currently 12.8 and feeling more like autumn. 12 degrees colder today than yesterday. So although today's temperature was about average for the time of year its has come as a shock to most.
-
23.3C here today. Bit gusty tho with an average wind speed of 21mph. Looking forward to colder days and nights. Feels strange when its so warm yet everywhere looks so autumnal.
-
Having looked through the ensembles from tonights 12z the operational from the GFS seems to be on the high side compared with the bulk of the other runs. There still appears to be a big dip as we head into October. Not sure what to read into this but a more seasonal feel could be on the cards during the first week in October.
Ecm maybe the first model to clock on to this cooler spell in October. Will feel very autumnal if that run verifys. May change but could be the start of trend, defiantly one to keep an eye on. All eyes on the 18z.
Stratosphere Temperature Watch 2011/2012

Strangely not. I believe a warming of the stratosphere would split the polar vortex allowing high pressure to build in the arctic increasing our chances of a colder shot from the north/east. We have an VERY cold stratosphere at the moment and that's what causes the typical low pressure moving west to east over the British Isles keeping us away from the coldest weather. Still a learner so please correct me experts if this is misleading or incorrect.
Regarding last Nov/Dec cold spell did we have a SSW prior to this, if so when and was it a major warming?
