Wow, you have some proper winter weather Roman - i'm jealous!

Good to hear it's getting a bit more wintry for you Martin!  You can really see on the rainfall radar on the met office how that polar front splits into the distinct warm and cold sectors over Northern Ireland.  Met office are updating their weather advisories / warnings very rapidly this afternoon!  I should be seeing snow proper in the next couple of 4 hours or so...  Grin

Jonathan, no depth at all because it isn't cold enough for it to settle yet, it has stopped now but further showers should move in tonight when the temp drops so I expect (hope) it will stay on the ground then.

18Z Update

Atlantic Situation remains firmly blocked with large upper and surface anticylones over Greenland and NW Atlantic.  Cold front is surging south over the UK with arctic airmass moving south - though this will be modified over the next 48 hrs by convection and its assoc latent heat and SSTs

Cold front /occlusion is now moving south, the 12Z GFS, NAE & HIRLAM have a fair representation of the front.  Front is classic rearward sloping feature with cold high density hair surging into the rear of the feature.  Ahead of it - Higher WBPT is being advected in to form a kind of Pseudo warm sector.   Very cold air in the SE this evening (-5 to -7 in places) Milder air is now present on western coasts.

As the front comes south it remains a messy affair - Rain, Sleet and Snow.  Mostly Rain/Sleet in Coastal NW England, Lowland Wales and SW England, (largely within the 4C WBPT isotherm....... progressively more wintry as you move east away from this.  Midlands into Eastern England mostly Snow, though initial brief period of sleet, and again in the SE, largely Snow.  Again some heavy snow likely as the front comes SE across the Midlands towards the NW Home COunties. (best forcing is towards the east)

1-3cm in the West Midlands and CS England as the front clears, 3-6cm further east, and isolated more on the Chilterns where a second trough comes SE during early Sunday Morning.

Very cold tonight in the Snowfields (Tulloch Bridge already -8C) and this the theme for the next few nights.

Sunday sees a lot of snow showers across Scotland and N Ireland . Need to watch the very cold clusters nr 65N 3W where a Polar Low may form and sink S.  Significant risk of heavy snow and large accumulations across  NE N Ireland, SW Scotland and into N England.

Question Marks remain into next week-- I will discuss these tomorrow

Storm Forecast Issued: 2009-12-19 23:29:00
Valid: 2009-12-19 23:00:00 - 2009-12-20 22:59:00

Regions Affected
Northern Ireland, north Wales, Northwest England, western Ireland and most of Scotland (excluding the far east, which is included in the WATCH, along with the remainder of the United Kingdom)

Synopsis

A complex area of LOW pressure situated over northern United Kingdom will dominate the weather during Sunday. Behind a cold front sinking southeastwards during the early hours, exiting into France by dawn, a cold and unstable Arctic airmass is advected southwards across the whole of the British Isles.

Showers will develop, due to the large temperature differences between the upper atmosphere and the sea surface - these mainly affecting those areas exposed to the gusty northwesterly winds (thus northern and western areas). The showers will be frequent, forming into bands (or troughs) at times, and providing significant snowfall in places due to the cold airmass. Electrical activity seems possible, and hence thundersnow is a strong possibility.

There is a chance for a weak funnel or waterspout to develop. Showers will continue to affect the same areas well into the night.

Change that to 6" here now, we tried to drive out but the car could barely make it so we had to retreat home bringing an end to my plan for snow images today which is a shame. Got a few snaps from the garden though. Some convection here and mammatus, more snow showers to come. Watch out for the Moon, Jupiter, Mercury conjunction after sunset and for aurora later.

Hope you get some shots Jonathan.
