  • A cooler air mass remain is place across much of BC behind the last low pressure system that moved through yesterday
  • Below seasonal, nay 'winter' temps are locked in over the central and northern half of the province 
  • For us on the coast, a ridge is attempting to clear out some of that lingering cloud this morning; looks like a mix of sun and cloud at least by later this afternoon
  • The next low pressure system however will reach the north coast tomorrow morning bringing strong winds and rain to Haida Gwaii. Clouds ahead of the system will prevail for Vancouver tomorrow before the rain slides south tomorrow overnight and into Wednesday
  • For Thursday a brief ridge sets up again for likely the best day this week because an Alaskan low will drop southward for a soggy Fri/Sat/Sun and a general cooling trend as the low pulls down cooler air
  • High for Vancouver will be around the normal of 10-13 this week but overnight lows are dropping by the times we get to the weekend to the low single digits. I would not say we are done with winter yet as that cold Alaskan low has the potential to bring winter back
  • More snow for the passes will likely not be a huge problem though this week anyway as freezing levels remain generally above the pass levels

Cold Temperatures For Much of Canada This Week
  • A series of waves in the jet stream will send a few round of winter temps from west to east across the country. The first is settled in across the prairies today with -20 wind chills across AB, SK & MB!
  • The cold air will reach southern Ontario for Thu/Fri, dropping temps from 15 degrees tomorrow in Toronto to 1 with snow for Thursday
  • The next 'cold outbreak' will start in BC late this weekend but something to keep an eye on for it's progression across the country after that

US Tornado Potential Today & Through the Week
  • A large contrast in air masses (thanks in part to the cold air across the Prairies today) is colliding with warm moist air on the other side of the country
  • The collision line was over Kansas & Missouri yesterday where a round of storms produced at least one tornado
  • Today the line is shifting eastward and the risk is increasing for dangerous t-storms & tornadoes from Dallas to Kansas City
  • And each day this week, the line of t-storms will slowly track eastward. By Wed/Thu the risk will line up with Mississippi valley and into southern Ontario
More hurricanes to hit Western Europe due to global warming
  • A new paper published today expects that Europe will see a large increase in Hurricane Sandy-like hybrid storms by the end of the century due to global warming

Ice cores preserve 1,800 years of climate
  • Two ice cores from the tropical Peruvian Andes reveal Earth's detailed tropical climate history year by year for nearly 1,800 years, researchers say.
  • Researchers at Ohio State University who retrieved the cores from a Peruvian ice cap in 2003 are calling them "Rosetta Stone" samples with which to compare other climate histories from Earth's tropical and subtropical regions over the last two millennia.
