More Record-Warmth Today...Few Showers Tomorrow..Then the Cool-Down...Nov 13th
- An unstable, but mild airmass is in place across the south coast of BC. Chance of an isolated shower will remain in the forecast especially for the north shore and through the Fraser Valley this afternoon and again tomorrow morning
- But in between the clouds, gorgeous blues skies along with temps in the mid-teens again today. YVR broke a temp a 1953 record yesterday at 14.6, as did West Vancouver, breaking a 2001 record at 16.8
- Winds will be shifting & picking up tomorrow afternoon bringing the risk for showers along with cool air. Sun should be back by the afteroon though.
- But it will be Friday that the temps really drop as a stronger system slides in bringing end of week rain and dropping snow levels
- Afternoon highs starting Friday into early next week will struggle to get much above 6 degrees! And as overnight lows also drop as we head into the weekend, the rain may turn to wet flurries at higher elevations for Vancouver on Saturday! And this means heavy snow for the mountains
- Hoping for a sunny but cold one on Sunday but flurries still in the forecast next week!
Super Typhoon Haiyan's Intensification and Unusually Warm Sub-Surface Waters
- An interesting discussion on the remarkable warming of the sub-surface Pacific waters east of the Philippines in recent decades...could be responsible for the rapid intensification of Super Typhoon Haiyan.
- Hurricanes are heat engines, which means they take heat energy out of the ocean, and convert it to kinetic energy in the form of wind.
- According to recent studies - the sub-surface waters east of the Philippines have warmed dramatically over the past twenty years.
- Some good graphics showing the path of Haiyan over the warmer waters...almost like a pathway right into the Philippines
- Also, interesting data from the iCyclone chase team who took measurements on the ground in Tacloban during the strike. Not official yet but already helping to tell the story:
Big Temperature Changes Ahead for Western Canada
- After record breaking warmth (high teens) for parts of BC & AB yesterday & today...arctic air is a coming
- An Arctic front pushing through on tomorrow will help temperatures drop several degrees by Friday and the weekend for Vancouver & Calgary
- By Saturday, many places will see a daytime high colder than -10 in Alberta with up to 10 cm for central AB
- Meanwhile Vancouver could see wet snow this weekend at higher elevations
- But all of this good news for the skis and boards...
Missing Heat' Discovery Prompts New Estimate of Global Warming
- An interdisciplinary team of researchers (including Canadian) say they have found 'missing heat' in the climate system, casting doubt on suggestions that global warming has slowed or stopped over the past decade.
