Which Type(s) Of Snowfall Event(s) Are Best In Your Location?

[Bobby]

Battleground events is where we get most of our snow from. The altitude helps when it's marginal and the surrounding mountains intensify the precipitation . We've had some decent falls in recent years from NWly streamers though, one last December gave about 10 inches in a few hours. Some most recent battleground snowfalls here...

I have no idea what would be best for my location in North oxfordshire

18th December last yr gave 10 inches so that type I guess.

[cheeky_monkey]

For my locations i have lived

Chelmsford - Essex - Easterly, Streamers any time from December through February..can dump large amounts of snow

Exeter - Devon - Easterly (Channel low) January & February..can cause blizzards and huge amounts of Snow and drifts (unfortunately rare)

Edmonton - Canada..can be from anywhere at any time from October - May..prolonged cold enusre anything that falls from the sky is snow in the winter months..a slow moving developing Alberta clipper can dump largish falls of dry blowing snow followed by brutal cold.

[greybing]

Any ideas what would be best for Manchester.Im guessing battleground.Also what is a streamer.

Of the above the 2 in 2009 were channel lows pushing E/NE with cold air over the UK, they weren't really battleground events.

Feb 9h 2007 wasn't really a battle ground event either,

However the other 2 were and I can generally see why battleground events are very good for your location.

[Richard2901]

A convective northerly is the best for snowfall here as it brings lots of sunshine and interesting cloudscapes as well as snow.

Best time to get them is in December - over Christmas - though as we saw in 2006 even with the stronger sun northerlies can still deliver plenty of snow as late as March.

Any direction from north west clockwise to east usually delivers the goods here although easterlies are usually grey and have been feeble in recent years. South easterlies are useless giving just rain or sleet while westerlies and south westerlies are dry.

Let's keep these coming in.

Even if an area or type of snowfall is already there, you can still post it and we could see which type of snowfall in which area is the best for the most members.

Also I'd like to see more localized events like Streamers from certain geographical features. We're also waiting for posts from the Northern Isles, Highlands, SW Scotland & the Lothians Borders and East Midlands.

[I remember Atlantic 252]

yeah, easterly definitely the snowiest wind direction here, not just convective either, 18th and 22 Dec last year, 8-9 feb 07, 5th Feb 09, 18th Feb 10, 19th Nov 96,

17th Dec 1997, 01 Jan 1997, 30th Dec 1996, 13th Jan 2010, most of them frontal snow, but still an easterly wind

but on other wind directions frontal snow fails usually, 12 Mar 2006 failure, 29-30th Dec 2000, failure, 27/28th Dec 2010 failure

[GulberwickWeather]

Shame the questions didn't allow more than one response! Up here anything with a Northern element si good for snow N/NE/NW and we've also had snow from the west. E or SE is no good at all. Even a short lived cold spell like 2-3 days is enough to give us some decent snowfall though. Although I've gone for a Polar low setup as being best, showers will do it as well as we can get some pretty beefy showers driven on strong winds.

Being an island group surrounded by water we tend not to get hard frosts like on the mainland but we can get dumped on as troughs etc pass over us. Also being and isolated island group we can get weather thats "not as forecast" i.e. different to that being progged for the mainland.

[BlueHedgehog074]

Types: Snow showers and frontal snow

Region: West Midands

Area: Solihull

Geographical Features Involved: Fairly flat land near the middle of England. A fair way inland from the surround seas of the UK.

Suitable Conditions: For frontal snow, battleground events with a front approaching from the South/South-West banging against colder air to the East. Most of these frontal events start off as heavy snow, but if the mild air winds out, they can sometimes turn to rain before clearing to the North-East/North.

Very occasionaly, we may get the odd front running down from the North making it here delivering some light to moderate snowfall.

For convective snow, winds from a direct North-Easterly direction tends to be ideal for this area, with 5 to 10 minute snow/wintry hail showers of moderate intensity. Some can be squally too, with sudden strong gusts of wind. We can also do reasonably well with a East-North-East wind too, although if streamers form, they may just miss us to the North. this happened last year near the end of November, although we did manange to get some light snow from the odd part of a streamer making it a little further South.

Snow showers from a North-West direction can also reach here, although from past experiences, they can be more of a hit and miss affair and don't always make it as far as here (probably thanks to some of the North-Western hilly areas in Wales the snow showers have to travel over).

Duration: Single event = 2+ hours.

Depths: Frontal snow: 2 to 10cm, and perhaps upto 20cm if the snowfall is particularly heavy and lasts for a long time. And for snow showers: 0 to 5cm.

Effects: Snowfalls of around 10cm+ can cause a lot of disruption to buses and sometimes, train networks. I walked 4 miles home in the snow last year when we had that December the 18th event with the buses not running.

Very hard ice-days can also cause some disruption, especially if their is a layer of icy snow on top.

Example: February 8th and 9th 2007. Brought two heavy frontal snowfalls from the South-West bringing 12cm in total:

Event News: http://news.bbc.co.uk/1/hi/6338151.stm

Extra Information: We usually tend to get 5 to 10 snowfalls/showers every Winter. Sometimes more or less than that depending on how mild, cold and dry the Winter has been.

[Northernlights]

N/ NE winds are best for here with covective showers off the North Sea along with polar lows which can be so localised that you can see a line drawn acrooss the land where snowfall starts and finishes. Late winter is probably best for this to give you the massive contrasts in colours between the the sea sky and clouds due to stronger light.Have also seen the odd battleground event over the years quite often on S or SE winds but we need a very vigourous depression or front to give us any heavy snowfall as the Cairngorms to the south usually save us from anything to severe(snowshadow effect)

[Norrance]

I can answer for my home area in Highland Perthshire. There battleground situations are great as it stays just that bit colder for longer in that area. From Blackford/Auchterarder through to the Dunkeld and Aberfeldy areas battleground and frontal snow delivers. Easterlies also are good but the convective showers can sometimes lose a bit of their oomph by the time they get well inland.

For the East West valleys PM Westerlies can also give large falls from showers such as in Jan 1984.

Northerly convection tends to die out as it reaches the Southern Highlands.

Aberfeldy's snow lying days for the last three Winters are 65, 65 and 37 in 2008/9. [22 in 2007/8].Not bad for an altitude of 100 mtrs asl!

I also lived in Aberdeen for a few years but I see that Richard has covered that area well.

I'd say here, the best set up (in terms of giving the most snowfall) would be a battleground event, or (although not exactly listed) a channel low. Though it would have to be cold enough and not marginal at low levels, which usually means significant enough embedded cold, or very cold easterly winds pushing against the front and under cutting it.

A geographical feature would I guess be the English Channel. Dartmoor/Exmoor tend to block weather/showers more here as we tend to be in the rain (or snow) shadow of them.

There have been a few examples recently including the 5th/6th February 2009 which is an example where it was marginal at low levels, with me getting a patchy ~1cm cover! A few miles further inland, and Exeter had an inch or 2 of wet/slushy snow I think, but the hills near me had at least 4-5 inches of good quality 'powdery-ish' snow clinging to all the tree branches where it wasn't blown turning them white, which I was lucky enough to see, while other parts of Devon especially towards Mid Devon had up to a foot. Dartmoor may have had even more. (also saw the day after)

The 6th January 2010 was a kind of channel low that I think moved down from the NE (not sliding along from the W) that gave 6cm of snow here and wasn't very marginal. This lasted 6-7 days and was the most snow I'd seen at my house at the time. Further east there was up to a foot (I remember 27cm at Reading)

The 20th December 2010 event is by far the best snow event I've seen here - at least 20cm on top of some snow already lying giving totals that were nearly a foot in places. TWS mentioned this in one if his earlier posts in this thread, though I'd suggest this was a small channel low rather than from a PM airmass as I remember it sliding along the channel and me being concerned it might turn to rain here or warm up a bit during the day. Thankfully that didn't happen too much. (Though thinking about it, the airmass in place was Polar/Arctic maritime!)

We had a couple snowfalls on the 17th/18th from Arctic/polar maritime flow - probably the most picturesque snow I have seen.

The 20th December 2010 event caused this here:
