Not sure if this is the best place, However this an interesting read Re: the ultra cold that the east is having recently.. http://news.sciencemag.org/asia/2014/10/arctic-sea-ice-loss-responsible-eurasias-deep-chill From the article: A deadly winter cold wave settled over Europe at the end of January 2012, blanketing much of the continent with snow and ultimately causing more than 800 deaths. Such severe winters are becoming more common across Eurasia—and some scientists contend that sea ice loss, by altering circulation patterns, is ultimately to blame for these frequent deep chills. But as climate simulations haven’t yet parsed out the atmospheric response to the loss of sea ice, its influence on Eurasian winters remains a question mark. Now, a new modeling study finds a link between these winters and the decline of sea ice in a part of the Arctic Ocean known as the Barents-Kara sea region, bordering Norway and Russia. The researchers identified several key circulation patterns that affected the winter temperatures from 1979 to 2013, particularly the Arctic Oscillation (a climate pattern that circulates around the Arctic Ocean and tends to confine colder air to the polar latitudes) and a second pattern they call Warm Arctic and Cold Eurasia (WACE), which they found correlates to sea ice loss as well as to particularly strong winters. WACE has been going strong since about 2004 or 2005—and as a result, the probability of severe winters has more than doubled in central Eurasia, they report online today in Nature Geoscience. But these severe winters may be a temporary phase within longer term warming: By the end of the century, the researchers report, the Arctic Oscillation could overpower the cooling effect from WACE—and winter temperatures over Eurasia will gradually increase.

ESTOFEX.ORG have some interesting information today especially how the jet interacts with this low pressure. Storm Forecast Valid: Tue 21 Oct 2014 06:00 to Wed 22 Oct 2014 06:00 UTC Issued: Mon 20 Oct 2014 22:47 Forecaster: PISTOTNIK A level 1 and level 2 were issued for SE England, BeNeLux, N and E France, Switzerland, central and S Germany, the Czech Republic and Austria mainly for severe wind gusts and to a lesser extent for tornadoes. A level 1 and level 2 were issued for NE Italy, the N Adriatic Sea, Slovenia, the N parts of Croatia, Bosnia-Hercegovina and Serbia, and the W parts of Hungary and Slovakia mainly for severe wind gusts and tornadoes, and to a lesser extent for excessive precipitation. A level 1 was issued from Scotland into NW Germany mainly for severe wind gusts. SYNOPSIS A strong zonal flow is present across Europe. A first cyclone tracks eastward into Russia and brings wintry conditions into Scandinavia and northeastern Europe in its wake. Behind a transient and progressive ridge over central Europe, the next cyclone (ex-hurricane "Gonzalo") moves from Scotland towards Denmark, and a new trough ejects from the British Isles into central Europe. Quiescent conditions prevail over southwestern and southern Europe, apart from quickly increasing Mistral and Tramontana winds over the western Mediterranean Sea at the rear flank of the amplifying central European trough. DISCUSSION ... England into BeNeLux, NE France, Switzerland, central and S Germany, Czech Republic, Austria ... A powerful jet streak (>50 m/s at 500 hPa) digs southeastward at the flank of the Scottish cyclone. In the course of the day, its axis is forecast to point across northern and eastern France into Switzerland and northern Italy. Very strong vorticity advection will be present at its cyclonic flank, which is forecast to catch up with the cold front around 09 UTC over southeastern England. Under the influence of its lift, a band of neutral to slightly unstable profiles will likely establish ahead of the cold front, largely overlapping with the very strong wind field of the jet streak. In the 09 to 15 UTC time frame, thunderstorms become increasingly likely while the cold front moves from England into the Netherlands, Belgium and northern France. Storms will soon organize into multicells and bowing lines, and the risk of severe wind gusts increases betimes. In a strongly sheared and helical flow even in the lowest levels (15-20 m/s of 0-1 km shear and 200-400 m^2/s^2 of 0-1 km storm-relative helicity, respectively), any updraft that manages to stay more discrete may also acquire rotation and produce a tornado. After 15 UTC the limited area models show convincing signals that the convective activity will be bundled into one dominant line along the cold front, as it moves into Germany, Luxemburg and eastern France. Deep-layer shear increases from 20 m/s near the northern fringe of the unstable area to almost 50 m/s beneath the jet axis over France and Switzerland. A level 2 for severe wind gusts is issued for those areas where a robust overlap of strong shear, strong synoptic lift and at least a little CAPE exists, surrounded by a broad level 1. Limiting factors are the relaxing shear towards the north and the decreasing depth of the convective line towards the south, which makes it less likely that the immense shear beneath the jet axis can be fully consumed. Until 00 UTC, the convective line is forecast to cross central and southern Germany, the Czech Republic and much of Austria. Along the northern Alpine rim, ageostrophic flow due to channelling (indicated by forecast pressure tendencies up to 10hPa/3h) may further enhance the strength of the wind gusts. ... NE Italy, N Adriatic Sea, Slovenia, N parts of Croatia, Bosnia-Hercegovina and Serbia, and W parts of Hungary and Slovakia ... Unseasonably rich low-level moisture is present in the range of an old frontal boundary, left over by the departing low over Russia. Backing and increasing low-level winds in response to strong pressure falls in the evening may advect further Adriatic moisture into the northern Balkans and onto the Pannonian plains, maybe even into Slovakia (depending on a possible mesolow development along the approaching cold front). The most aggressive solutions (WRF) show surface dewpoints around 14°C and 925 hPa dewpoints around 12°C over Slovenia, Croatia and western Hungary at midnight, yielding CAPE up to 500 J/kg under a strongly sheared and helical flow. With the arrival of the vorticity lobe aloft, prefrontal storms may start to form in the late evening over eastern Austria, western Hungary, Slovenia and northeastern Italy. They will probably be elevated in the beginning, but in case they manage to root down to the surface, they can easily turn into tornadic supercells in this almost saturated and strongly sheared environment. Any prefrontal activity will sooner or later be engulfed by the following convective line, which will cross much of Hungary and the northern Balkans until Wednesday 06 UTC. While it gradually decelerates and outruns the strongest wind field and synoptic-scale lift, the risk of severe wind gusts will start to decrease. However, a limited risk of training storms with localized flooding may evolve instead, especially in Slovenia and Croatia where storms from the northern Adriatic Sea may move onshore for a few hours while they are undercut by northeasterly surface winds and turn elevated. ... Scotland and E England, as well as BeNeLux and NW Germany coasts after 15 UTC... Showers and weakly electrified thunderstorms will form in the stream of deeply mixed polar air behind the cold front. Vertical wind shear will be limited, but the strong background wind field may support wind gusts slightly above 25 m/s even with poorly organized convection. Besides, an isolated tornado is not ruled out along windward coasts where the sudden increase of surface friction ramps up low-level wind shear. The exact track of the compact center of the cyclone is still uncertain. The majority of forecast models simulate a landfall in Denmark towards the end of the forecast period, which could result in a dramatic increase of wind speeds in a confined area in northwestern Germany near its back-bent occlusion. Since it is unclear how much deep convection will be involved and if this will happen at all until Wednesday 06 UTC, no level 2 was issued.

Amen, Just a line of CB's to my west.. Not moving at all.

We had a little rain today. Not even a slight breeze here.

Any update on this? How is it still looking? My brain breaks when we have a large low like this coming in with the Jet playing silly at the same time.. Just too much for me to look at with any confidence.

Ill go with.. There wont be any.

Distant thunder to my south. Wooooo

Absolutely honking it down here.. No thunder though. It appears to of died.

Dude.. Not sure where your looking... But we about to get something major.. Looking to my south now, Its a flash every second. Going offline now.. Gonna get real here soon.. very soon .. Gonna go move the car,...

Looked south? Flashing constant..

Storm to the south is doing the best part of 1 strike every 2 seconds. The sky to my south is just while flashes now.

Looks like SE is about to be "pounded" again.. Central South getting hit now and building like something out of hell. South west gonna be hit in the next few hours I think.

Wow... intense! next 48 hours are gonna be great for some people! so much potential coming from the south! it is... it just seems to be 5 mins out at the moment. exploding all over the south now

Huge storm here... Not being picked up by blitzortung yet.. HUGE

100% rain,

Just noticed the rate of convection and strikes.. Checked Estofex for an update as clearly a mesoscale discussion needs to be announced. and shock horror.... There is: http://www.estofex.org/cgi-bin/polygon/showforecast.cgi?map=yes&fcstfile=2014071820_201407181712_-_mesoscalediscussion.xml Proper gonna explode now!

Dont be fooled by the direction of the storms. The whole system itself is pushing north. So while "these" ones may not do anything for us.. Its what builds behind.

Epic wow! The speed at the increase of intensity. Its exploded... Gone from a few strikes to 700+ in 20 mins. eDIT: 1000+

Oh HELLS yeah!

Estofex are normally spot on with their forecasts. This give me hope of some massive imports..

Water & Dust & Pollution mostly.

Is it bad that the words loads of CAPE, and a cold front gave me shivvers ?

Wow, Looking at the Sat24 today, Looks like zero chance for sunshine around here today. I hope something pops up later down south. Last nights storm was something else. Flashes every 5 to 6 seconds. Constant rumbling. 1 in 10 was CG strikes however most was IC.

This explosion here is what we like!
