Dry & Cool Forecast Continues...Warm-up for End of Week...Jan 15th

High pressure continues to be the dominating factor in Vancouver's weather over the next few days. YVR dropped down to 1 degree but many other locations dipped below zero. Untreated roads/sidewalks did ice up this morning.

Snow still on ground..

-An inversion is developing..where the lower levels of the atmosphere are cooler than above. So mountain temps will be warmer than the ground over next couple of days! Temps for us will be cool still in the overnights (-2/-3) but afternoon highs today, tomorrow & Thursday a few degrees above zero.
- The warm-up to seasonal will come for Friday as our high pressure system sinks south and east.. so we are still under the influence for sunny skies but shifting winds will bring as back to seasonal 6/7 in the afternoons. A decent weekend forecast at this point.
- Warming of the higher elevations has brought avalanche risk to considerable for many regions (3/5 on risk scale).
- Air quality will continue to deteriorate with our inversion and stagnant air pattern.
- Fog and lower stratus may also come into play over the next couple of days but it will be patchy and should burn off with the sun.
 
Prairie Clipper
- A low pressure system is now tracking from Northern Alberta into central Saskatchewan. It is helping to usher in Arctco temperatures, as we talked about yesterday. But it is also bringing a quick 5-10 cm and gusty winds as it races across to Ontario for the end of the week
 
Globe experiences 10th warmest year on record in 2012
- The Earth has apparently entered a new climate regime in which it is locked into warmer than normal temperatures. In 2012 - the temperature of the globe once again rose above the long-term average, joining the 35 years preceding it.
- Specifically, the Earth's temperature in 2012 was the 10th warmest year since records began in 1880 NOAA announced today. NASA, which independently evaluates global temperature records, found it was the 9th warmest year on record.

Deep Under Antarctica, Looking for Signs of Life
- Three major scientific projects set out this season to seek evidence of life in lakes deep under the Antarctic ice -- evidence that could provide clues in the search for evidence of life elsewhere in the solar system..
- But only one of the projects, a $10 million expedition from the United States, has a chance of identifying long-hidden microbes before the weather on the frigid continent puts an end to drilling in about a month.
- The British effort, ran into technical trouble and had to be called off for this season. An expedition from Russia will be returning samples to be analysed later.

Discovery of largest structure in Universe questions Einstein's assumption
- The Huge-LQG is 4 billion light years in length, that is, light would take 4 billion years to cross it end to end. That's nearly one-twentieth the estimated diameter of the whole known Universe. The team used data from the Sloan Digital Sky Survey, the most comprehensive 3D map of the universe
- Till the discovery of the Huge-LGQ, it was assumed that the upper limit of size for cosmic structures was somewhere around one billion light years.
