No snow for me so far this Autunm/winter season but im hopefull that that will change later this month.
I last saw snow 11 months ago back in early Jan when i had about 3 inches.

Many thanks. The attention to detail under which the competition was managed was impressive as always.
The competition is just another element here that makes netweather.tv the best on the web!
Well done AF in winning the competition. I cant belive how well i did myself this year. Also well done to LP

I prefer prolonged Easterly spells because for my location as there is always a better chance of snow with showers coming in off the Irish sea. For me Northerly cold spells usually mean dry conditions,not always but alot of the time.

I think a cold Dec in store, i will go for around a degree below average at 4.0c

A cold frosty night last night with some freezing fog and severe frost. Min temp was -1.4c (coldest nov temp at my location since the cold snap in nov 2005).
Currently still frosty with fog,current temp -0.2c B)
-
-3.4c and very frosty
If it stays clear where you stormforce you should see -5c or -6c i would imagine
As for me i might see -2c,not bad for my location in late Nov,currently 0.7c here
-
Sharp frost this morning,lowest temp last night was 0.3c (coldest so far this month). A cold crisp day with plenty of clear skies,although it got rather cloudy for a while during the evening. Max temp today 3.6c (coldest day so far this season). Currently mostly clear again,some frost. Current temp 1.7c

Cold and clear here with a light breeze,current temp 2.4c
-
Winter hardly started at all the last 2 "winters"
Seriously though, its always been Dec 1st for me,although i often think of the 2nd half of Nov as kind of early winter
-
A mostly cloudy day with the odd spot of light rain but there were some bright spells also. Max temp 10.4c,currently partly cloudy with a temp of 9.0c

Great stuff guys
Im looking forward to Thursday. You guys certainly know your stuff.
BTW the video and sound worked well for me

Had some frost this morning with last nights min getting down to 1.8c,a lovely sunny morning. It clouded up later in the day but remained dry. Currently cloudy, current temp 7.1c (which is also todays max,so far)
-
Great photos

SP
MY min last night was 9.4.
My max today of 11.2c was only about 2hrs ago. The Temps the last few days have certainly been boring. But heres to next week hopefully. :lol:

The polar vortex is a persistent large-scale anti clockwise cyclonic circulation pattern in the middle and upper troposphere and the stratosphere, centered generally in the polar regions of each hemisphere. In the Arctic, the vortex is asymmetric and typically features a trough (an elongated area of low pressure) over eastern North America and over NE Siberia. The polar vortex is not a surface pattern. It tends to be well expressed at upper levels of the atmosphere (that is, above about five kilometers). When the polar vortex is strong, deep purples can be seen on the 500hPa charts as shown below:
When these deep purples are situated over Greenland and Iceland then lower pressure dominates in the upper atmosphere which has a knock on effect to the lower levels. This tends to drive Atlantic based weather to these shores, giving us mild, wet weather. The stronger the polar vortex over the Arctic the Arctic Oscillation (known as the AO) will be more positive. When the AO is negative the polar vortex tends to be weaker and disrupted with areas of upper high pressure forming. These can 'block' the normal path of westerly surface low pressure systems and are known as blocking highs, and in the right position can lead to colder polar air heading southwards towards us.
How does it affect the BI if the pv is near NE Siberia? I presume its better to have it there then near Greenland for a chance of polar air?

A very interesting forecast and if it comes off it would be a very interesting winter.
I wish BFTP and Roger the best of luck with it

A hoar frost is the frost that occurs on the more say funny objects like trees i think. Is this the frost where the tempeature has to be below zero for though?
I dont think to get an hoar frost the temp has to be below 0c,ive seen hoar frosts when the temp was 1 or 2 degrees
-
Can someone tells me the difference between an air frost and a hoar frost?? Am i right in saying a hoar frost is classed as a hoar frost if you see frost on trees for example?.
Ground frosts can occur between 1-4C i think, depend on the ground/grass temperture though.
I think an hoar frost is that really kind of thick frost you can get on the grass etc and i suppose on trees too,i think you get hoar frosts when the humidity is fairly high and of course if its cold enough for a frost.
Like how much frost you get can often depend on how much humidity is in the air,if the humidity is low and the temp was -2c for example you might not get as much frost,if just say the temp was 0c but the humidity in the air was alot higher.
