TODAY'S WEATHER ACROSS UK & EUROPE
By Mark Vogan

WITH THE EXCEPTIONS OF SCANDINAVIA AND RUSSIA, ALL OF EUROPE IS FLOODED BY WARM, ATLANTIC AIR, BUT THINGS LOOK TO BE CHANGING AROUND JAN 25TH!

Just take a look at how stormy the UK has become as the breakdown of the Greenland block has allowed an open door of Atlantic air to return to Britain as well as an active jet stream which storm systems form and ride along. This jet which typically roars across northern Britain at this time of year has been displaced down across Spain and the Med, bringing stormy, colder than normal conditions much farther south than normal thanks to that bloocking high pressure system over Greenland, but now that the NAO (North Atlantic Oscillation) is positive, we see lower pressures at our latitude and the colder is ejected north and east for a change therefore stormy, wetter, milder weather has indeed returned and milder air has indeed flooded pretty much all of Europe creating flooding as there was such a cold, snowy spell last month for all of us. We have seen a very wet day across Britain, particularly over western and central Scotland and Cumbria. Sustained winds of between 25-35 mph have blew in from the typically mild southwest direction with gusts beyond 50 mph on exposed coasts and hills and has helped raise temperatures to 11C (51 degrees) here at my house and in several locales across western and central Scotland high's have reached 12C, an amazing 53-54 degrees and well above normal for this time of year.

Check out this vid from the state tourism deparment. You can have a clear idea of how much ice accumulated at Chipinque Park which is above 4000 ft and less than 8 mi from downtown. Local rangers claim old trees fell due to the weight of ice, something really uncommon. Ice started around tuesday night and lasted until yesterday by noon. Lowest temps around metropolitan area fluctuated between 0-2°C or around 32- 36°F with thursday being the coldest day so far.

Flurries could be in the air for Sunday's Bears game; threat of more significant early week snow being monitored

Bears fans, hardly strangers over the years to bitter subzero wind chills and even snow during home play-off games, are likely to take Sunday's modest brand of January chill and restrained winds in relative stride. Mother Nature has served up far harsher conditions in the past.

Flurries may flutter to earth at times Sunday, the by-product of a disturbance predicted in the area. The early take on the system is that snows will be light--most likely on the order of a dusting in some areas. Hints by one prediction model that a small feature referred to by meteorologists as a "meso-low" may develop and sit over southern Lake Michigan at some point Sunday. It's the type of system which could enhance snowfall more than currently predicted. But the details of such features aren't easily pinned down this far in advance. Prospects for a meso-low getting involved in Sunday's snow production are low--but they're not zero--so this is a situation which will be monitored.

While chilly Sunday, the game's midday kick-off is to take place amid temperatures in the low 20s--not warm, to be sure--but only a moderate level of chill by January standards. The light/variable winds predicted during the game are likely to fall in the 7 to 8 mph range generating wind chills in the teens.

The weather next week is to become challenging on several fronts. Snow and bitter cold are to enter the picture. Early projections suggest moisture levels with a vigorous southeast-bound Alberta Clipper-type system may be sufficient to produce snowfalls approaching 4 inches Monday afternoon and night in the Chicago area. The system has traversed the Pacific beneath the nose of an eye-catching 200 mph jet stream. Winds aloft of that strength are capable of producing especially vigorous weather systems. This disturbance is no exception but is projected to track across southern Wisconsin--not generally a track which produces Chicago's biggest snows. But warmth and a prolific flow of moisture up its front side plus the insistence of a majority of computer forecast models that the bulk of its precipitation is to fall as snow or a snow/sleet mix, supports predictions of up to 4 inches of snow. More precise accumulation figures will become available in coming days. READ MORE

Cross polar jet stream infuses frigid Canadian air mass with Siberian air; some Yukon temps down 50-degrees in the past week

Temperatures have plunged over the past week in northwest Canada. At Whitehorse in the Yukon Territory, readings dropped from a high of +11-degrees on Monday to a Friday morning low of -40-degrees--a 51-degree dive in just 5 days. It's part of an intensification of a frigid air mass there which has resulted from an infusion of bitter Siberian air riding a powerful cross-polar jet stream from Russia. Barometric pressures in the region have soared as the cold, dense air has strengthened. Peak barometer readings late Friday soared to 1058 mb. (31.24 inches).

Winter's coldest air to sweep into Chicago in two powerful waves next week, the first Tuesday; a second Thursday and Friday

It's unusual for arctic highs of such strength not to ultimately spill southward into the U.S. The expectation is the first wave of cold air is to send Chicago temperatures into a tailspin Tuesday--and that a second surge of bitterly cold air is to plunge into the area Thursday and Friday. Together, they threaten to send metro area temperatures to the lowest levels to date this winter and potentially among the coldest readings of the past two years.
